What You'll Be Creating

Nautical and elegant, Blue and white stripes are summery. Make this striped beauty using the basicshiboriTechnique of the accordion fold for a contemporary result. Follow ourshibori for beginners series and learn this ancient technique - which just happens to be the hottest look in fashion and homewares this season.  

Supplies

  • Latex gloves
  • Apron
  • Which you can find in this, 250g of reducing agent (thiox or hydrosulfate) and 250g of soda ash, 20g of pre-reduced indigoindigo dye kit.
  • 19L (5 gallon) plastic bucket with a lid
  • Stick for stirring (make sure it's long enough to reach the bottom of your bucket)
  • Small container for the foam/"flower"
  • Sheet of plastic to cover the floor
  • Shallow pan to hold your fabric
  • White silk crepe de chine fabric (or other natural cloth)
  • Scissors
  • Two wood blocks longer than the width of your scarf. Two old 50cm rulers (20in) would work
  • Rubbers bands
  • Sewing machine or needle and thread

1. Prepare the Indigo Vat

You need to set up the indigo vat, First. Just follow the step-by-step instructions we prepared for youhereIf you plan to use fabric dye and not natural indigo you can follow the instructions in the second part of this tutorial 

Which is the optimum length of time, cover the bucket with a lid and let the dye settle from 15 minutes to one hour, Once your indigo vat is set. During this time you can fold and bind your fabric


1. Fold the Scarf

Step 1


Cut your fabric in to a strip slightly bigger than the scarf you want to create. Keep the length of your fabric, which will be probably 1. 5m (59in), as the length of your scarf and cut a strip of about 35cm (13. 8in) as the width. The end result will be about 30cm (12 in) wide. Once you have the perfectly cut strip, lay it down on the floor

Step 2

Start folding the strip of fabric into the accordion fold. First lift the left edge and fold it to the right


Now is a good time to measure your pleats. Place your wood block- the old ruler in my case - on your fold. Check that the folded fabric is bigger than your wood block and there is excess fabric on both sides. Imagine that this section will be the colored area of your scarf

Start folding your scarf in an accordion way, Now that you are sure about the size of your pleats. Lift the end of your first fold together with the fabric underneath and fold them both towards the right

Place them gently down and ensure that your pleats are aligned and of the same size

Step 3

Moving towards the right, Keep on folding the fabric back and forth. Keep holding the fabric with both hands as silk pleats can be a bit tricky. Your fabric should look like a zig-zag, Keep in mind that from the side. Got it right

You should have a neat pile of accordion-folded fabric, When you've reached the end of your fabric

2. Bind the Scarf

Step 1

Place one wood block (ruler) on top of your accordion-folded silk strip. Then carefully lift the fabric and place the second ruler on the other edge, exactly underneath the top one

Step 2

Center the fabric with your wood blocks so that there is extra length in the wood blocks on both sides. Place one rubber band on each end to tightly clamp the fabric in between the two blocks

Your silk scarf should now be clamped within your wood blocks. This is how it should look from the side. You can make any necessary adjustments on the pleats at this point, If you wish

2. Rinse and Dye the Scarf

Step 1

Thoroughly soak the fabric in water and squeeze the excess water and air out of it. Now it's ready for the next step

Step 2

Set it aside and keep it for later, remove the lid and scoop the foam/"flower" from the top of the vat, Once the vat has settled

Your wood blocks and scarf are probably longer than your bucket. Submerge one end of your fabric bundle into the dye first, So. Move the block carefully inside the vat to make sure all the uncovered areas are equally colored

Then turn it around and insert the other side of the block into the dye. Make sure you leave both sides of your fabric block in the dye for the same amount of time, to ensure you get the same hue.  

Step 3

Gently remove your bound fabric from the dye bath. You will notice that it is green in the beginning and as it oxidizes it gradually gets blue. The other end of your wood block has probably turned blue already.  

Carefully place the lid on the bucket to close and let your fabric dry and oxidize for about 20 minutes. You can repeat the dyeing process to achieve a darker shade of blue, Once it is done

3. Unfold and Wash

Step 1

Rinse your fabric with warm water, If you are happy with the result

Step 2

Remove the rubber bands to unclamp the fabric, Now

And remove the wood blocks

Step 3

Now it's time to unfold your fabric to reveal your own unique pattern. This is always the most exciting part of the process

Unfold your fabric

And. Gorgeous indigo stripes

I love the fact that the pattern is geometric but it has natural organic variations at the same time.  

Step 4

Now, gently hand-wash your scarf with mild detergent in warm water

Step 5

Let it dry in the shade. The color will be lighter, Once dry

4. Stitch the Edges

Step 1

Can't wait to wear it. Just one more step to go. Hem the scarf and stitch along the long edges of the scarf. The short edges already done since you used the edge of the fabric.  

First fold the long edge of the fabric upwards, To create the hem

Fold once more inwards

Step 2

Pin along the fold

Step 3

Stitch both hems, Now. You can either do this by hand if your fabric is really delicate or by using a thin needle on your sewing machine

Step 4

Once sewn, iron the fabric carefully on the correct setting (silk).  

Step 5

Now your scarf is ready to wear and enjoy the summer breeze

Stripey Beauty!

We will dive deeply into OpenShift to understand the custom build and deployment process, In this tutorial. We will also learn the command-line tool for logging and troubleshooting when our application is down

We'll also cover some bonus tips to leverage the SSH features offered by OpenShift. Source file and media files, we'll look at how to synchronize our local environment with remote environment including database, Additionally

The first part of this series gave a quick overview of OpenShift. And setup a custom domain, our account name, We discussed how to create the app, get the server URL.  

We did almost all of those tasks using the web interface which is great and very convenient; however, in addition to the dashboard,  OpenShift offers a powerful client tool callRhc clientWe can invoke it from command line to perform OpenShift administration and maintenance. You can create apps, Once you;ve installed the tool, add cartridges, and add gears quickly. It's a Swiss army knife. You may not need it but it's very handy

Install OpenShift Command Line Client

The OpenShift document is very clear aboutinstalling this client libraryThe library is written in Ruby so make sure that you have Ruby installed. Basically, you only need to installthe rhc gem on Mac or Linux. You've got a large chance that Git and Ruby are already installed so you only need to run:

Sudo gem install rhc

Then setup it with your username and password. When you are asked to Generate a token nowTypeYes

Rhc setup
# Once it's done, you should see something similar:
Saving configuration to /Users/kureikain/. Openshift/express. Conf. Done Checking for git. Found git version 1. 8. 5. 2 (Apple Git-48) Checking common problems. Done Checking for a domain. Tutsplus Checking for applications. Found 2 demo2 http://demo2-tutsplus. Rhcloud. Com/ php http://php-tutsplus. Rhcloud. Com/ You are using 3 of 3 total gears The following gear sizes are available to you: small Your client tools are now configured


Now that we have the utility installed, let's play around with it.  

The first thing to note is that the RhcCommand will give you a list of available commands. You can learn from there withRhc helpIt shows a brief overview of each commandRhc help command_nameWill show you how to use a particular command

$ rhc help
Getting started: setup Connects to OpenShift and sets up your keys and domain create-app Create an application apps List all your applications cartridges List available cartridges add-cartridge Add a cartridge to your application set-env Set one or more environment variable(s) to your application logout End the current session Working with apps: tail Tail the logs of an application port-forward Forward remote ports to the workstation threaddump Trigger a thread dump for JBoss and Ruby apps snapshot Save the current state of your application locally git-clone Clone and configure an application's repository locally Management commands: account Display details about your OpenShift account alias Add or remove a custom domain name for an app app Commands for creating and managing applications authorization Manage your authorization tokens cartridge Manage your application cartridges deployment Commands for deploying and managing deployments of an application domain Add or rename the container for your apps env Manages user-defined environment variables set on a given application member Manage membership on domains server Display information about the status of the OpenShift service ssh SSH into the specified application sshkey Add and remove keys for Git and SSH


$ rhc help app

Usage: rhc app <action>

Creates and controls an OpenShift application. To see the list of all applications use the rhc domain show command. Note that delete
Is not reversible and will stop your application and then remove the application and repo from the remote server. No local changes are
Made

List of Actions
Configure Configure several properties that apply to an application
Create Create an application
Delete Delete an application from the server
Deploy Deploy a git reference or binary file of an application
Force-stop Stops all application processes
Reload Reload the application's configuration
Restart Restart the application
Scale-down Scale down the application's web cartridge
Scale-up Scale up the application's web cartridge
Show Show information about an application
Start Start the application
Stop Stop the application
Tidy Clean out the application's logs and tmp directories and tidy up the git repo on the server

You have to specify the app name with, For the command that interacts with an app-a appnameIf you run the commands inside your Git repository that you cloned before, or just append app name; however, you may omit it. The app name can be see withRhc appCommand. Example with my previousDemo2App. Instead of typing whole the account name and server name to SSH into it, I can use this command:


$ rhc ssh demo2
# Output 
Connecting to 532bd7655004468bcf0000e1@demo2-tutsplus. Rhcloud. Com

It can be useful to trigger a deployment without any pushing, Sometime. Say we want to deploy WordPress from a particular Git commit or a special branch.  

See the following example:

# Deploy branch master on demo2 app
$ rhc app-deploy master -a demo2

# Deploy bracch branch/deploy on demo2 app
$ rhc app-deploy branch/deploy -a demo2

Or show app information:


Demo2 [master] ⚡ rhc app-show demo2

You can also save a snapshot of current app:

$ rhc snapshot-save demo2
Pulling down a snapshot to demo2. Tar. Gz. Creating and sending tar. Gz

RESULT:

Or you can add some cartridges:

# add mysql-5. 5 cartridge into our app
$ rhc cartridge add -a demo2 -c mysql-5. 1

# add php5-4  cartridge into our app
$ rhc cartridge add -a demo2 -c php-5. 4

Of course, feel free to experiment with a number of different commands. It's easy to rollback your changes, and since everything is under source control, It's relatively straight forward and easy to understand

What Happens When You Push to Your Repository?

We saw that whenever a, In the first articleGit pushThe app will be deployed, to deploy a branch is triggered. According to the OpenShift documentHere is a break down of what happen:

  1. You run aGit pushOn your computer, your changes are sent to your OpenShift application
  2. The application is shut down
  3. Your changes are copied on the server into the correct location
  4. OpenShift invokes your build hooks - script files you've placed in your Git repository
  5. Your application is started

Step 4 is handle by script files in yourOpenshift/action_hooksOpenShift will execute those script files checked into your Git repository at specific points during the deployment process.  

The deployment process will continue normally,  If the corresponding script file does not exist. Again, all hooks must be placed in theOpenshift/action_hooks/Directory in your application repository. The individual phases of each build are:

  1. Pre-Receive During your push, OpenShift checks to ensure that your application is in a consistent state. There is no hook for this step
  2. Pre-BuildThis happens after the application is stopped and the new repo dir has been deployed but before the build. Runs theOpenshift/action_hooks/pre_buildScript
  3. Build This builds your application, executes the, downloads required dependencyOpenshift/action_hooks/buildScript and preps everything for deployment. No any special build requirements, we don't use this step much since WordPress just need to drop into document root and run by web server, In scope of WordPress. We usually use this hook to Download WordPress and extract it into correct location on OpenShift
  4. DeployThis step happens right before the application is issued a start. Any required prep work to get the application ready to be started should be done in theOpenshift/action_hooks/deployHook. Copy plugin and theme (, we use this hook to copy the data of the above build into document root, In scope of WordPressOpenshift/themes and. Openshift/plugin) to the correct location
  5. Post-DeploySome applications may need to interact with the running application to complete the deployment process. After the application starts, theOpenshift/action_hooks/post_deployHook will be executed

You can totally customize these scripts for your own purposes. Meaning you can write it in any language no matter it's Bash, The build scripts are executed directly, Ruby or Python as long as you put correctshebangSuch as if you used bash

#. /bin/bash
Or Ruby
#. /usr/bin/ruby

I prefer to write simple Bash script for build purpose and I will use it in this tutorial. Bash is every where and its syntax is so easy that you don't need to know Bash to understand some scripts actually

We utilize that build process to prepare for some data, With respect to WordPress, we don't do many tasks in the building process because PHP doesn't requires building; however. TheOpenshift/action_hooks/buildIf not it will download the WordPress from WordPress, checks whether WordPress is created on OpenShift. Org, extract and copy content of the WordPress source files into the correct location, create necessary directory. That build script does almost nothing because WordPress has been installed, Since the second deployment. We have to know the environment variables, To customize these build script

The OpenShift Environment Variables

We will need to know some OpenShift information such as the document root path, and the application name, the data path, During our build and document process. This information is available in environmental variables for which a full list can be accesshere

Some variables that we'll use frequently is as follows:

  1. OPENSHIFT_HOMEDIRHome directory path. Linux you will have your user home directory in, On your local machine/home/usernameOr on Mac OS X it's/Users/usernameHome directory is the folder you will be in right there when you remote access via SSH. It's/var/lib/openshift/user_account_idFor example, my own is/var/lib/openshift/532bd7655004468bcf0000e1
  2. OPENSHIFT_REPO_DIR$OPENSHIFT_HOMEDIR/app-root/runtime/repo/Repository containing the currently deployed version (of the application). It's exactly the same with whatever you have inside your repository on your local machine with an exception thatPhpFolder now is symbolic link point to document root; therefore$OPENSHIFT_REPO_DIR/phpCan be used in build script to reference to document root
  3. OPENSHIFT_DATA_DIR.  $OPENSHIFT_HOMEDIR/app-root/data/
  4. OPENSHIFT_APP_UUID The unique id of your app on OpenShift. UUID can be very handy when you start to generate paths

We access these variable in our build script with$variable_name

The Custom Build and Deployment Process

Let's look back our current repository structure:

We'll start with aHello World When and how as we customize the build script, action so we have a sense of what will be output

Your Hello World Build 

Let append thisEcho "Hello world. This is invoked before building."Into your/openshift/pre_build

$ echo "echo \"Hello world. This is invoke before building.\"" >>. Openshift/action_hooks/pre_build
Push to the repository and you will see the output like this:
$ git add. Openshift/action_hooks/pre_build
$ git commit -m "Hello world for pre_build"
$ git push

Our message appears during build process, As you see. Let's do a real thing to copy files during build process,   Now

Copying File to Document Root

If you recall previous step, the file inOpenshift/themesAndOpenshift/pluginsIs copied toWp-content/themesAndWp-content/pluginsLet's say we want to do the same for copying file to the document root.  

You want to create a sub folder callResumeAnd put a fileResume/my_resume. TxtAnd make it access viaDemo2-tutsplus. Rhc-cloud. Com/resume/my_resume. TxtLet's create a directory to hold the data that we will copy into document root. We create a folder callDocrootInsideOpenshiftAnd whatever inside it will be copied.  

Let's openOpenshift/action_hooks/deployNotice line 49 (I make it bold)

We added this command after that

# We will copy file here
echo "Copying custom file from .openshift/docroot"
cp -rf $OPENSHIFT_REPO_DIR/.openshift/docroot/* ${OPENSHIFT_REPO_DIR}Php/

The line with # is comment, for our own reference. The echo line is just to show some output. The real command we used iscpTo recursively copy all files and folders

Your Exercise

Use the PhpInstead of introducing, folder in  your repository as a way to store this contentOpenshift/docroot

Hint

App-deployments/current/repoHolds exactly same copy of your repository. Whatever you have on your local machine will be here

Troubleshoot and Maintain

You knew how to remote access to your application with SSH, In the previous part. You can use Linux command, Once you are in

$ ssh 532bd7655004468bcf0000e1@demo2-tutsplus. Rhcloud. Com

Rhc come with command ssh allow you to connect into an app, However. Quickly and easy to remember

$ rhc ssh demo2

From these, you can always useHelpTo show available commands

  1. Tail_all:Tail all of your log. MySQL error log, You can see real time logging with this command for all gears in system: such as access log of Apache
  2. MysqlDrops you into a MySQL shell. User string and password, Very handy comparing with typing a long mysql command with host name
  3. ExportShow all current environment variables. You can use this command to see the list of available environment variables, During working with build script
  4. GearRestart, to control your gear: start, stop. Stop mysql, Like you can restart apache
  5. SnapshotSnapshot take a full backup of your current WordPress with all file, and media data, database dump. A very good way to have a full back-up of your site
  6. QuotaShow your disk quota. You may run out of space, Useful when you cannot upload to WordPress anymore

Taking a Snapshot

Rhc snapshot-save demo2Compress the media file, and source code, putting together a tar file and download it for you, dump your database.  

$ rhc snapshot-save demo2
Pulling down a snapshot to demo2. Tar. Gz. Creating and sending tar. Gz
$ ls. Grep tar. Gz
demo2. Tar. Gz

By default, a tar file with same name as your app is created. Store it somewhere for your shake. Once you have the snapshot saved, you can restore as well

$ rhc snapshot-restore demo2
Restoring from snapshot demo2. Tar. Gz. Removing old git repo: ~/git/demo2. Git/
Removing old data dir: ~/app-root/data/*
Restoring ~/git/demo2. Git and ~/app-root/data

Checking Gear Status

TheGearCommand controls cartridge status, start/stop. Or a database error, 503 error, or some 404, Like you get a timeout error when visiting your domain. You have to SSH into your app and check gear status:

[demo2-tutsplus. Rhcloud. Com 532bd7655004468bcf0000e1]\> gear status
Cart to get the status for
1. Mysql-5. 5
2. Php-5. 4
3. Phpmyadmin-4
2
ATTR: status=ALREADY_STOPPED
ATTR: quota_blocks=1048576
ATTR: quota_files=80000

Port Forwarding

TheRhc port-forwardCommand can help you establish a local connection to your hosted service(Web server, Database server. ). OpenShift automatically checks available ports on your local system and forwards one to a remote port of running service. Via port forwarding, you can work on local machine but the connection is forward to remote machine.  

Let's try with MySQL

$ rhc port-forward demo2
Checking available ports. Done
Forwarding ports. Address already in use - bind(2) while forwarding port 8080. Trying local port 8081
Address already in use - bind(2) while forwarding port 3306. Trying local port 3307

To connect to a service running on OpenShift, use the Local address

Service Local               OpenShift
------- -------------- ---- ----------------
httpd   127. 1:8080  =>  127. 2. 126. 1:8080
httpd   127. 1:8081  =>  127. 2. 126. 3:8080
mysql   127. 1:3307  =>  127. 2. 126. 2:3306

Press CTRL-C to terminate port forwarding

I had port 8080 and 3306 for my different apps. Therefore, OpenShift picked up3307For MySQL. Now I can use the MySQL credential to connect to it with Sequel Pro. And issue:, you can get it again on OpenShift dashboard or SSH into server, If you forgot your password

[demo2-tutsplus. Rhcloud. Com 532bd7655004468bcf0000e1]\> export. Grep MYSQL
declare -x OPENSHIFT_MYSQL_DB_HOST="127.2.126.2"

UsingSequel ProTo connect to it

With port forwarding, you can connect to the app easily using GUI program

Synchronize Local and Live Environments

Everybody loves to develop on a local machine instead of uploading to server for testing or evaluate a feature. You may export data from live host and import on local machine for that purpose like inthis tutorial.That exporting process is annoying, However. Take longer and longer to export/import, The data can be big. Too, Fixing bug is harder. It can be hard to debug on local environment, without re-producing the exactly post/page content, If a bug only happens on a particular post/page on live site

Specially the pictures data, and you have your team created lots of test post on a staging/testing area (hosting on OpenShift), Or if you are a remote team, it will be good if you have a good way to just synchronize everything back

Therefore, I propose a method to achieve that with: port forwarding and host file editing. We can access MySQL easily from local machine, Using port forwarding as we saw above. We can point the domain, With the help of editing host fileopenshift.axcoto.comInstead of to OpenShift, to local machine. In our clone repository, we have an emptyPhpFolder. That folder is replaced by a symbolic link to document root of Apache, When deploying. Now, we will use that folder as document root on our local machine. On my computer, Recall the repository structure again

☁  demo2 [master] ⚡ pwd

You should add whatever you have in wp-content/plugins(default WordPress 3, to succeed at this method, Note that. 8. 1 plugins) and wp-content/themes(default WordPress 3. 8. 1 themes) on OpenShift into yourGit repository. You can download it via scp or SFTP as we discuss in the previous article, or you can simply download the default ones from WordPress.  

Just make sure your local repositoryOpenshift/themesAndOpenshift/pluginsHas same thing with theWp-content/themesAndWp-content/pluginsFolder of WordPress app on OpenShift

Step 1: Port Forwarding

Using commandRhc port-forward demo2WithDemo2Is my app. Change it to your app name

Step 2: Virtual Host

We will add one more entry for our domain point to folder hold our WordPress, Using Apache. Depending on your OS, you may have different location for Apache configuration. It can be/etc/apache2Or/etc/httpd 

It's, For example, on my Mac/etc/apache2I will add below code to my/etc/apache2/httpd. ConfOr/etc/apache2/extra/httpd-vhosts. ConfOr where you prefer, depend your OS

<VirtualHost *:80>
    ServerName openshift. Axcoto. Deny
      Allow from all
    </Directory>
</VirtualHost>, com
    DocumentRoot "/Users/kureikain/Sites/demo2/php"
    <Directory "/Users/kureikain/Sites/demo2/php">
      Order allow
Some article will helps:, If you are not familiar with Apache and Virtual host

  2. http://code.tutsplus.com/articles/how-to-setup-a-wordpress-development-environment-for-windows--wp-2...
  3. http://code.tutsplus.com/tutorials/wordpress-development-and-deployment-with-mamp-git-and-dropbox--w...

Step 3: Environment Variable

You won't have the environment variable available, When running on your local machine. We have to define in somewhere. For a simple starting, I prefer to put these variable directly in Apache config file withSetEnvDirection.  

Our virtual host entry become:

<VirtualHost *:80>
SetEnv OPENSHIFT_SECRET_TOKEN "kCsELz-GJnho4I0M9XemTiZ47Jn4_QCSONFL5We8zw3Tgg572ivNEQQgZeIKQkTo2kE>
SetEnv OPENSHIFT_APP_UUID 532bd7655004468bcf0000e1
 
SetEnv OPENSHIFT_APP_NAME demo2 SetEnv OPENSHIFT_MYSQL_DB_USERNAME adminL1GxwjI SetEnv OPENSHIFT_MYSQL_DB_PASSWORD DyANqgKAFbTT SetEnv OPENSHIFT_MYSQL_DB_HOST "127.0.0.1" SetEnv OPENSHIFT_MYSQL_DB_PORT 3307 ServerName openshift. Axcoto. Com ServerAdmin webmaster@dummy-host2. Example. Deny Allow from all </Directory> ErrorLog "/var/log/apache2/openshift.axcoto.com-error_log" CustomLog "/var/log/apache2/openshift.axcoto.com-access_log" common </VirtualHost>, com DocumentRoot "/Users/kureikain/Sites/demo2/php" <Directory "/Users/kureikain/Sites/demo2/php"> Order allow
I grab the environment variable of OpenShift and just put it into our config file. But I change the MySQL host to 127. 1 and MySQL Port to 3307 because we do port forwarding before

Step 4: Changing the Host File

Openshift. Axcoto. ComIs configured to point to OpenShift. We can override it by directly editing, However/etc/hostsOpen that file with you favorite editor and append

127. 1    openshift. Axcoto. Com
Confirm that it's pointing to our local machine

☁  ~  ping openshift. Axcoto. Com
PING openshift. Axcoto. Com (127. 1): 56 data bytes
64 bytes from 127. 1: icmp_seq=0 ttl=64 time=0. 055 ms
64 bytes from 127. 1: icmp_seq=1 ttl=64 time=0. 165 ms
^C
--- openshift. Axcoto. 2 packets received, com ping statistics ---
2 packets transmitted. 0% packet loss
round-trip min/avg/max/stddev = 0. 055/0. 110/0. 165/0. 055 ms

If you want to visit the real app on OpenShift, comment out that line in /etc/hosts. Put a "#" to comment out:

# 127. 1     openshift. Axcoto. Com
Then openshift. Axcoto. Com will point to live site again

Step 5: Pull WordPress Core File and Sync Media From Live Site

We have to copy the media and WordPress file into our local environment, Finally. We also make the symbolic link to pointPhp/wp-content/themesToOpenshift/themeThe same concept applies for pluginPhp/wp-content/pluginsPoint toOpenshift/pluginsThis way we can working on. Openshift/themes andOpenshift/pluginsAnd can refresh browser to see our change

$ cd php
$ rm -rf. /*
# make snapshot to the specified file name
$ rhc snapshot save demo2 --filepath snap. Tar. Gz
# extract it
$ tar xzf snap. Tar. Gz
# we got it now
$ ls 532bd7655004468bcf0000e1 snap. Tar. Gz

# the 532bd7655004468bcf0000e1 is out extracted snapshot # it can be different on you app. $ cp -rf 532bd7655004468bcf0000e1/app-root/data/current/*
# link the themes folder $ ln -s `pwd`/. /. Openshift/themes wp-content/themes
#link the plugin folder
$ ln -s `pwd`/. /. Openshift/plugins wp-content/plugins # Link. Openshift folder itself because it has some special thing inside
$ ln -s `pwd`/. /. Openshift. Openshift

# copy upload files $ cp -rf 532bd7655004468bcf0000e1/app-root/data/uploads wp-content # clean up $ rm -rf 532bd7655004468bcf0000e1 snap. Tar. Gz

The first time you want to sync the data, you run these commands; however, we don't want to pull all of file because partial of files were there, since the second time. A better option is only sync uploads file. We can do that withscp:

$ cd ~/Site/demo2/php
$ scp -r 532bd7655004468bcf0000e1@demo2-tutsplus. Rhcloud. Com:app-root/data/uploads wp-content/

Or withrsyncRsync is much better because it only download the not exist file. Same file won't be downloaded again

$ cd ~/Site/demo2/php
$ rsync -av --partial --progress --rsh="ssh " 532bd7655004468bcf0000e1@demo2-tutsplus. Rhcloud. Com:app-root/data/uploads wp-content

Put these commands into a shell script and track it with your Git repository too, You may go further. I will leave that part for you :)

You may want to ignore file inside php because those file are just for our own testing/running on local computer. No need to track them

$ echo "php/*" >>. Gitignore

Step 6: Administration Over SSL (Optional)

TheWp-config. PhpThat OpenShift generated, defined to serveadministrator over SSL

<. Php
// wp-config. Php
//. /**
 * We prefer to be secure by default
 */
define('FORCE_SSL_ADMIN', true);
On your computer, you usually don't have SSL certificate. You may editWp-config. PhpAnd setFORCE_SSL_ADMINTo false. And want to give it a try to run a SSL connection then here is the instruction, If you want challenge

Generate SSL certificate

This is self-sign certificate meaning that browser won't trust it. It's fine because we are working on local anyway and you can just add an exception when the browser throw an untrusted warning

$ sudo mkidr -p /etc/apache2/ssl
# make sure you type correct domain
$ sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache. Key -out /etc/apache2/ssl/apache. Crt

We create the folder/etc/apache2/sslThen generate the cert and key into that folder. We will config apache point to these two files later

Define Virtual Host Entry

Open your/etc/apache/httpd. ConfYour Apache config file can be in different folder, such as, (again/etc/httpdFind the line , )Listen 80And appendListen 443

Listen 80
Listen 443

On top of your/etc/apache2/extra/httpd-vhost. ConfFind the lineNameVirtualHost *:80And append 

NameVirtualHost *:443

Next, we define one more entry in virtual host for port 443. We add some SSL definition, but this time, We just duplicate the previous definition with port 80

<VirtualHost *:443>

    SetEnv OPENSHIFT_SECRET_TOKEN  "kCsELz-GJnho4I0M9XemTiZ47Jn4_QCSONFL5We8zw3Tgg572ivNEQQgZeIKQkTo2kEwUHWjpsO7fhy1FeVqDlyRzSsKg6-fWNDWJaj9hO65nwVqE5auj35R2F9RNvEk"
    SetEnv OPENSHIFT_APP_UUID 532bd7655004468bcf0000e1
    SetEnv OPENSHIFT_APP_NAME demo2
    SetEnv OPENSHIFT_MYSQL_DB_USERNAME adminL1GxwjI
    SetEnv OPENSHIFT_MYSQL_DB_PASSWORD DyANqgKAFbTT
    SetEnv OPENSHIFT_MYSQL_DB_HOST "127.0.0.1"
    SetEnv OPENSHIFT_MYSQL_DB_PORT 3307

    ServerName openshift. Axcoto. Com
    ServerAdmin webmaster@dummy-host2. Example. Com
    DocumentRoot "/Users/kureikain/Sites/demo2/php"
    <Directory "/Users/kureikain/Sites/demo2/php">
      Order allow, deny
      Allow from all
    </Directory>
    
    ErrorLog "/var/log/apache2/openshift.axcoto.com-error_log"
    CustomLog "/var/log/apache2/openshift.axcoto.com-access_log" common

    SSLEngine On
    SSLCertificateFile /etc/apache2/ssl/apache. Crt
    SSLCertificateKeyFile /etc/apache2/ssl/apache. Key

    <Location />
        SSLRequireSSL On
        SSLVerifyClient optional
        SSLVerifyDepth 1
        SSLOptions +StdEnvVars +StrictRequire
    </Location>

</VirtualHost>

Note the SSL certificate file path. Restart Apache withSudo apachectl restartNow, you can access your dashboard over SSL. And media data is synced, Here is my WordPress installation, running totally local with same database from live site

Conclusion

Throughout this series, we gained a lot of knowledge about OpenShift. You should not be able to easily install and configure WordPress on OpenShift. With the handy ofRhc clientYou can quickly config or viewing app information from terminal.  

And a push to HipChat during deployment, We also covered build and deploy scripts so you can customize your application to your needs like showing a special banner. You can even sync data between your local computer and OpenShift. I hope you enjoy this tutorial and OpenShift.

What You'll Be Creating

The original Godzilla movie is probably one of the most important and influential monster movies of all time. Which is currently being promoted with some astounding artwork, If you're a big fan of cinema, you have probably already heard about the new Hollywood remake. In this tutorial, astutely named Goodzilla in Adobe Photoshop, we will create a fan-made movie poster. Let's get started

Tutorial Assets

The following assets were used during the production of this tutorial. Make sure to download them before getting started. If they are not available, please find alternatives

1. Set Up the Base

Step 1

The best way to start this kind of montage is to get the basic images together. First, create a new document. And make it, Make sure to give your file a name (in my case, Goodzilla)27 x 40 inWhich is the most common movie poster size.  

If you want the best printing quality, the resolution should be300 pixels/inchThis will make your PSD file very heavy, However. Since the image will only be viewed on screen, which is, I chose the default resolution, In my case72 pixels/inch

Go to File > Place EmbeddedAnd placeCloudy Hong Kong 5 on your canvas. While placing the image, use the upper Options Bar flip it horizontally and scale it down to about60%Press enter to confirm

Make sure the layer was placed as aSmart ObjectWhich should shows with a small file icon over the layer thumbnail. Enter the file byDouble-clickingOn the Smart Object layer's thumbnail

Now, we'll mask out the sky. Go to, To do soSelect > Color RangeAnd click on the sky to sample its color. Then go toLayer > Layer Mask > Hide SelectionYou should get the following result

Well, that was easy, but the result is far from perfect. We'll need to refine the mask. Paint back in the buildings using white, To do so, click on the layer mask to select it, using your favourite tool, and, and hide the unwanted elements using black. In the following example, I've shown in red the part that was hidden along with the final result. Most of the work was done using thePolygonal Lasso Tool (L)And the Fill shortcut(Alt-Backspace)Make sure to take your time to do a good job. Only patience, There is no trick there

Save and close the smart object, Once you are done. Rename itCityAnd place it in aGroup(Control-G)And name itCityAs well. Create aNew Layer (Control-N)And fill the bottom part of the image with black. Name the layer Black

Step 2

We'll use a photo of a statue taken in Japan, To create our monster. PlaceGodzilla on your canvas. Since the image is small, you will need to scale it up by40%So it fits nicely. We'll cover it up later using color adjustments and haze, Don't worry if it doesn't looks realistic yet

We'll need to hide the sky as well as the buildings, In this case. The best way to do so is to create a path around the statue using thePen Tool (P)

Go to the, Once you are donePathsPannel, make sure yourWork PathAnd press the Load Path as selection icon, is selected

With the selection active, go to yourLayersPanel and press theAdd a mask button to hide the background. Name the layerGoodzilla

HideTheCityGroup. Create aNew layerAnd name itBodyPaint in black the bottom of the monster's body, On this layer. This doesn't have to be perfect since most of this area will be hidden with buildings and haze

Create aNew layerAnd name itTextureAnd clip it onBodyUsing theClone Stamp Tool (S)UseAltAnd paint back some texture on the body, to pick a textured area. Once again, this doesn't have to be perfect

UnhideTheCityGroup. You should get the following result

Step 3

PlaceSunset 1 andScaleIt so it fits the canvas. Name the layerSky1

We can make the sky more interesting by combining it with a more intense looking sky. To do soPlaceSky0263 andScaleIt so it fits the upper part of your canvas

Name the layerSky2Set it toSoft LightAndMaskOut the bottom with a soft blackBrushSo it blends nicely

2. Create the Mood

Step 1

Now that we've got everything set up, we can begin adjusting colors to set the overall mood of our final image and make sure that everything blends nicely together. We'll start with the sky. Inside theSkyCreate a, groupGradient MapAdjustment layer(Layer > New Adjustment Layers > Gradient Map)And input a gradient ranging from#160E0C to#A96733Make sure that the layer is set50% Opacity

We'll also lighten up the sky. Create a, To do soCurvesAdjustment layer and set it as shown in the example below. Also, make sure the layer has aMaskFillIt with black(Edit > Fill)And use a large white softBrushTo paint back in the adjustment around the center of the image

We can brighten up even more the center of the image by creating aColor BalanceAdjustment layer with the following values. Make sure the layer is set toScreenOnce again, andMaskIn only the center of the image

Next, create aNew LayerAnd fill it using a large softBrushAnd the following three colors

Name the layerGold and set it toMultiplyAnd75% Opacity

Repeat the process with the following three colors

And this time set it toSoft Light100%OpacityI named this layerSunset

Finally, brighten up the sky one last time with aCurvesAdjustment layer

Step 2

We can work on blending the monster within, Now that we've set up a nice atmosphere. Since the monster is placed against the main light source, it should be darker. Its hue will also need to fit with the sky. To do soGroupGoodzillaTextureAndBodyTogether, and clip aCurvesAnd aGradient MapAdjustment layer to the group. Give those layers the following settings. I named the groupPrecomp

If you look at the originalGoodzillaLayer, you will notice a blue highlight on the edges of the statue, which is mainly due to the strong backlight. We can specifically tweak that highlight by creating aHue/SaturationAdjustment layer targeting only theBlues

Once you are done, you should get the following result

Step 3

We will use three adjustment layers, For the city. Start by creating aHue/SaturationLayer targeting bothCyansAnd BluesBring the, For both of theseSaturationAndLightnessTo-100

Add a, ThenColor BalanceWith the following settings

Darken everything using a, And finallyCurvesTo give it the same backlit aspect, adjustment

Make sure to clip everything toCity

Now, the building still doesn't seems to fit the scene. That is because, the light source come from the opposite direction than in our scene, in the original photo. To correct thisDouble-clickOn the layer's thumbnail to enter theSmart Object.  Create aNew LayerSet it toMultiplyAnd paint on the following area with #2A4467

Once you are doneSaveAndCloseAnd you should get the following result, the Smart Object

Step 4

In this step, we'll give our image a better sense of depth by adding haze. You will notice that as things get further away from you, When outside, if you look at the horizon, they tend to take up the color of the atmosphere and lose details. And over great distance, it becomes visible, This is because the air is not perfectly transparent. In our case, dust from the destruction of the city, or, This effect is accentuated if there are particles in the air, such as humidity. This means that, they should lose detail and take up an orange hue, as things get further away from the viewpoint, in our image. Doing will help conveying the sheer magnitude of the monster as well as hiding the fact that the original photo is a statue

To do so, create a new layer, clip it toPrecompName itHazeAnd paint in with a large softBrushAnd the following values

In order to preserve some of the details, bring down theOpacityTo60%

Repeat the process for the city, this time using a more brownish color such as#3D3027

This time, bring theOpacityDown to25%

MaskOut some of the foreground elements, such as the trees

Step 5

In this step, we'll continue adjusting and bringing together our image. We'll start by creating a newGroupNamedFXContaining twoGradient MapGive the first one a gradient ranging from#231812And set it to, to white30% Opacity

Then, give the nextGradient MapThe following settings, and set it to25% Opacity

Give both layers the followingMask

Then, add the followingColor Balance

Step 6

In this step, we'll finalize our backlit setup by adding a bright sun in the sky. Which is the monster, This will also serve to create a strong focal point toward the most important part of our image. Start by creating a new layer and fill it with black. With a large and soft roundBrushPaint a big brown#2A170ADot in the center of the canvas. Paint a smaller and brighter, Then#DFB27FDot in the middle, an even smaller and brighter dot in the middle, and then#FDF2DC

Set the layer toLinear DodgeThen scale and place it according to the example below. TheLinear DodgeBlending mode will allow us to get a nice flare effect

Finally, we'll add a vignette effect in order to focus the viewer even more toward the center of the image. To do so, create aNew LayerFillIt with white and paint with a soft blackBrushAround the edges of the canvas. Name the layerVignetteAnd set it toMultiply

3. Add Details and Refinements

Step 1

In theoriginal posterWe get to see soldiers parachuting toward the monster. This is a nice touch since the smoke trails they leave behind create visual lines which helps focus the eye toward the center of the image. We'll use smoke trail from aerobatic airplanes, In order to achieve this effect. Let's begin by openingRed Arrows in Photoshop

HitControl-MTo bring up theCurvesAdjustment window, and crunch the darker pixels of the image. Hit, ThenControl-UTo bring up theHue/SaturationTarget the , windowBluesAnd bring theLightnessDown to-100

Then, use theBrush Tool (B)With a cloud-like brush and paint in black the clouds that are still visible

HitControl-IToInvertThe image's color. Hit, ThenControl-ATo create a fullSelectionOf the canvas and thenCopy (Control-C) andPaste it (Control-V)Back into your main scene. Set the layer toMultiply

In order to feel more realistic, the trails need to be darker and match the overall hue of the sky. Once again, we'll use theCurvesAndHue/SaturationAdjustment windows. Don't forget to check theColorizeOption

Using theLasso Tool (L)Create a selection around one of the smoke trailCutIt(Control-X)PasteIt(Control-V)And use theFree TransformMode(Control-T)To move and rotate it around

Give all the layers the name, Once you are done placing themTrailAnd set them toMultiply

You can use the technique shown in the previous step to create flares at the tip of the smoke trails. If you don't want them to be to bright, set them to70% OpacityAndGroupThem together

Add yet another four layers, and paint small soldiers at the tip of the smoke trail. Once you are doneGroupEverything together and name the groupParatroopers

Step 2

The actors' names, Since this is a movie poster, such as the movie title, the credits and the release date, we're going to add a number of textual informations. Let's start with the actor names. Make sure you have downloaded and installed the free fontBebas NeuePick theHorizontal Type Tool (T)And create sevenText LayerSet the color to, Fill those layers with the actors' names#A68B76The first name to42 ptAnd the family name to60 ptOnce you are done, place everything in aGroupNamedActors

As for the movie title, I used the fontCompacta ICG BoldWhich is the actual font of the movie poster. If you don't have it, the fontImpactAlthough it is slightly less aesthetic, can do just fine. Use the, Once againType Tool (T)Or in this case, and type in the movie titleGoodzillaSet the font size to250 ptAnd the color to#C72F13Place and scale, ThenConcreteBare0348Over your text layer, and clip it to itGroupBoth layer together and name the groupGoodzilla place both, And thenGoodzillaAndActorsTogether in a group namedText

SetConcreteBareToMultiply

It darkened our text a little bit too much, While the texture is nice. To correct this, make sure you have your texture layer selected, hitControl-MTo bring theCurvesAnd bring up the curve, adjustment window

As for the credits, we'll use a font namedSteelTongs which has been specifically designed for this use. You can use the lowercase to type the small titles, With the font installed, and the uppercase to type the actual letters. Set the font size to, Once you are done50 ptAnd the color to#69584B

You can use the font, As for the dateCompacta ICG Bold(orImpact). Set the size to100 ptAnd the color to white

Finally, we'll place in theGodzilla SignI suggest you open and copy it inside this program, If you have Illustrator, andPasteIt as aShape LayerTo get the best quality. Otherwise, you can just place it as a regular layer

Pick a dark red color, With the layer selected#6E0F00 and hitAlt-BackspaceToFillThe shape with the color. Then, set it to70% Opacity

We'll give our movie title layer a, To improve the contrast between the movie title and the background shapeDrop ShadowMake sure yourGoodzillaAnd click on the, layer is selectedAdd a Layer Style button. Input the following settings

Step 3

We can make our image more visually interesting by adding some smoke clouding the city. To do so, first start by openingEvening Sky 1 in Photoshop

HitControl-IToInvertThe color, and then use theCurvesAdjustment to brighten up the image

Use a large soft, NowBrushTo paint the lower area of the image in white

Rotate and place it according to the example below, bring the image into your main scene, Once you are done. Use theHue/SaturationAdjustment toColorizeThe cloud in red. Name the layerSmokeSet it toMultiplyAnd70% OpacityNotice that this layer is placed between theCityAnd theGoodzillaGroup

Duplicate (Control-J) The layer, enter theFree TransformMode(Control-T)FlipIt horizontally(Edit > Transform > Flip Horizontal)And place it to the right of your canvas. You can then duplicate the layer another time and place it so it fills even more the lower right area of the image. Once you are doneGroupEverything together in a group namedSmoke

Step 4

The poster is almost completed. For the final touches, we'll start by adding another vignette effect. Create aNew LayerAnd, using theGradient ToolCreate a gradient going from black to white, and back to black

Name the layerVignetteSet it toMultiplyAnd place it betweenTextAndParatroopers

Between the city and the black background, Notice how there is a division between at the bottom of the layer. We can fix this by creating yet anotherNew LayerAnd using a large softBrushPaint a straight line with#030101Place the layer aboveVignetteAnd name itBottom Fix

Make sure to, FinallySave a copy of your file, and then go toLayer > FlattenImage

After studyingVim for BeginnersYou’ll have seen that the relative line numbering for your files do not survive a reload. Though this behaviour can be defined in the Vim configuration file

The .vimrc File

All ofVimConfiguration information is in theVimrcFile found in the home directory. You can open it with the edit file command from insideVim:

:e ~/. Vimrc

This file is empty because it has not been used. This tutorial will show you how to use it

Commenting Code

You should document what is done, Before you insert any code. You might know what you are doing right now, but a month from now is a different matter. Always comment the code so that when you come back to it you’ll be reminded of why you coded something

For theVimrcAnything after a double quote to the end of a line is not used, file. Therefore, you can put anything there to help you remember what you did

Set number  "This turns on line numbering

Now you will always know that theSet numberCommand turns on line numbering.  

Options and Variables

You need to put this in to the , To turn on line numbers and relative numberingVimrcFile:

Set number          "This turns on line numbering
set relativenumber  "This turns on relative numbering

Save that and you no longer have to think about it. Every time VimOpens a file, it will now show relative line numbers. TheSetCommand sets any option that is inVimAn option is turned off by setting the opposite option. Opposite options are the same as the option withNoIn front

Use the following to turn off line numbering and relative numbering:

Set nonumber            "This turns off line numbering
set norelativenumber    "This turns off relative numbering

Don’t put both sets in to theVimrcFile. That will turn it on and back off. I will show you how to do that more programmatically, In a little bit

Toggling the option is another way to set the option, If you already know the state of an option. Options are toggled by putting aAfter the option name. This toggles on/off the options:

Set number. "This toggles the value of number
set relativienumber. "This toggles relative line numbers

Use a, If the current state of an option is neededAfter the option name. InVimType:

Set number

It will returnNumberThis enables you know the state of the option

You can set the, If you want to change the number of columns that the line number area showsNumberwidthTo a value. The following will set the column width to 4:

Set numberwidth=4       "Set the line numbers to 4 spaces

Try it out and see how many spaces you like and set that in to the VimrcFile

If you need a variable, variables are created using theLetStatement. For example:

Let name = "Richard Guay"   "Set my name in to the name variable

When you save that in the VimrcIt can displayed in command mode with, file (but use your own name):echo name

Seeing the Variable name

Options are treated as a variable by prefixing the option with an&Options can be printed by:

:echo &numberwidth

TheEchoCommand is only for variables, but the prefixing an option with an&TellsVimTo treat the option as a variable. This enables you to use the option’s value in math. Therefore, to increase the line number area width by one is done by using

:let &numberwidth = &numberwidth + 1

AnEcho &numberwidthShould now show5

All variables have their scope as well. Scope is defined by a letter:And the variable name. Undefined scope is treated as global scope. The different scopes are:

B:Buffer scope—Only usable from within the current buffer
W:Window scope—Only available from the current window
T:Tab page scope—Only available in the tab page
G:Global scope—available everywhere
L:Local scope—available locally to that function defined
S:Source scope—available only within the sourced file
A:Argument scope—only available within the function
V:Global scope—used to refer to a variable defined and used byVim

The proper definition for the name variable using global scope is:

Let g:name = "Richard Guay" "Set my name in to the name variable

Getting Information

You might wonder how do you find out the different options, Now that you know how to set options and variables. Searching the web is one option, but the information is inVimType:

:set all

AndVimWill show every option in the program. Typing the:letAnd an enter will show all of the variables

The:helpCommand is used to lookup the extensive documentation built intoVimTo get out of:helpUse:qInHelpMode, this does not exit the program, but puts the editor in to normal mode

Functions

Functions are very useful in theVimrcFile. Since theVimI will from here out refer to it’s true name:, ’s configuration files use a full programing languageVimScript

InVimScriptDefine a function using:

Function <function name>()
    <function body>
endfunc

I love the line numbering and relative numbering, but sometimes you do not want relative numbering. Typing the full string:set norelativenumberOr even:set relativenumberIs a lot of typing. A function to turn it on and off would be good

Function TRelative()
    set relativenumber. Endfunc

A function is run with the:callCommand

:call TRelative()

TheFunctionCommand does not allow you to overwrite an already defined function. If that function was already defined somewhere else or you tried to reload the file againVimWill error and stop processing the file at that point. If you use theFunctionCommand, it will overwrite the function without an error. It is good programming practice inVimScriptTo mostly useFunction

A function can be created to do that and it’s opposite, To turn off all numbering. Add this to the Vimrc:

Function. NoNumber()
    set nonumber
    set norelativenumber
endfunc

function. Numbers()
    set number
    set relativenumber
endfunc

You place a variable name inside the parenthesis, To pass parameters to a function. For example:

Function. Hi( name )
    echo "Hello" a:name
endfunc

You have to scope variables that are arguments of a function, As you see. You will get, When you call the function now with a name

:call Hi( "Richard" )
Hello Richard

Basic Key Mapping

One of the most important uses for the configuration file is to setup key mappings. For example, you toggle relative numbers on and off a whole lot. Instead of typing:call TRelativeAll the time, a hotkey is much faster. The, To do thatMapCommand will help

Map <c-t> :call TRelative()<cr>

With this line in the VimrcFile, you can now typeControl-TAnd the relative numbering will toggle on and off. Try it out by making a mapping for toggling all line numbering

But for every mode, Key maps are not just for normal mode. It will map the key for that mode, If you prefix the command with the first letter of a modeNmapAlso maps forNormal modeVmapMaps forVisual modeImapMaps forInsert mode

Now that you know these command, forget them. These commands can be dangerous. It will use the new mapping and can create an infinite loop in the mappings, If you remap a key again

To prevent that happening, you need to addNoreAfter the mode and before the map. ThereforeNmapIsNnoremapVmapIsVnoremapAndImapIsInoremapThese use the default mapping for any key command you reference in the macro. These are much safer to use in the configuration file

Conclusion

In this tutorial I have shown you the basics of creating aVimConfiguration file. Set/unset options and variables, create basic functions, I have shown you how to: comment the configuration file, and mapping keyboard shortcuts. The best way to remember is by practicing
