  • In this blog I am going to share how to configure

    jenkins with grails

    on Ubuntu.

     

    Step 1.

    Install jenkins via command:

    wget http://pkg.jenkins-ci.org/debian/binary/jenkins_1.518_all.deb //download jenkins.deb file.

    Step 2.

    I assume that Java,Grails and latest version of Git is installed on your Machine if not please install them for further configuration.

    Now

    Install daemon via command: sudo apt-get install daemon

    Install jenkins via command: sudo dpkg -i filename.deb

    Step3 :

    The default port of jenkins is:8080 .If you want to change the port number go to etc/default directory and open jenkins file in editor and change the port no.

    Step 4 :

    Now start jenkins via command : sudo service jenkins start

    you will see on terminal

    Starting Jenkins Continuous Integration Server jenkins          [ OK ]

    after that, type in browser http://localhost:8888 //8888 is my default port for jenkins

    you will see the jenkins dashbord on browser

    Step5:

    Now click on manage jenkins and install required plugin

    Here is the list of required plugin for grails.

    1.Ant plugin 2.ChuckNorris plugin 3.Crediantials Plugin 4.External Monitor Job Type Plugin 5.Git Hub Api Plugin 6.Git hub plugin 7.java doc plugin 8.jenkins cvs plugin 9.jenkins git client plugin 10.jenkins git plugin 11.jenkins grails plugin 12.Jenkins mailer plugin 13.jenkins SSH plugin 14.Jenkins SSH slaves plugin 15.jenkins subversion plugin 16.Jenkins translation assistance plugin 17.Ldap plugin 18.Maven Integration Plugin 19.PAM Authentication plugin 20.Publish Over SSH plugin 21. SSH Crediantial plugin.

    Step 6 :

    After successfull installation of plugins:

    create a new job like this:

    • create a Job name

    • checked the radio button of Build a free-style software project

    • click OK

    Step 7 :

    • Now checked the radio button for Git

    • enter the uri of your git repeository.

     

    If you will see the error like

    Failed to connect to repository : Command "git ls-remote -h git@example.git HEAD" returned status code 128:

    stdout:

    stderr: fatal: 'git@example.git' does not appear to be a git repository

    fatal: The remote end hung up unexpectedly

    You have to do some more configuration:

    • Go to to the terminal

    • Run this command :sudo visudo

    • Add %jenkins ALL=NOPASSWD: ALL  in this file where sudo previlage is defined.and close the file.

    • login as jenkins user via command :sudo su jenkins

    • Create a .ssh directory in the jenkins home directory.

    • create the public private key pair like this.

    Generating SSH Keys:

    Step 1: Check for SSH keys

    First, we need to check for existing ssh keys on your computer. Open up Terminal and run:

    cd ~/.ssh # Checks to see if there is a directory named ".ssh" in your user directory

    If it says "No such file or directory" go to step 2. Otherwise, you already have an existing keypair, and you can skip to step 3.

    Step 2: Generate a new SSH key

    To generate a new SSH key, enter the code below. We want the default settings so when asked to enter a file in which to save the key, just press enter.

    ssh-keygen -t rsa -C "your_email@example.com" # Creates a new ssh key, using the provided email as a label # Generating public/private rsa key pair. # Enter file in which to save the key (/home/you/.ssh/id_rsa):

    Now you need to enter a passphrase or file.press enter without to write any thing.

    Which should give you something like this:

    Your identification has been saved in /home/you/.ssh/id_rsa. # Your public key has been saved in /home/you/.ssh/id_rsa.pub. # The key fingerprint is: # 01:0f:f4:3b:ca:85:d6:17:a1:7d:f0:68:9d:f0:a2:db your_email@example.com

    Step 3: Add your SSH key to GitHub

    Go to your Account Settings

     

    .

    Click "SSH Keys" in the left sidebar

    1. Click "Add SSH

    2. key"Paste your key into the "Key" field

    3. Click "Add key"

    1. Confirm the action by entering your GitHub password

    Step 4: Test everything out

    To make sure everything is working you'll now SSH to GitHub. When you do this, you will be asked to authenticate this action using your password, which for this purpose is the passphrase you created earlier. Don't change the git@github.com part. That's supposed to be there.

    Run the command on terminal:

    ssh -T git@github.com # Attempts to ssh to github

    You may see this warning:

    The authenticity of host 'github.com (207.97.227.239)' can't be established. # RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48. # Are you sure you want to continue connecting (yes/no)?

    Don't worry, this is supposed to happen. Verify that the fingerprint matches the one here and type "yes"

    Hi username! You've successfully authenticated, but GitHub does not # provide shell access.

    If that username is correct, you've successfully set up your SSH key. Don't worry about the shell access thing, you don't want that anyway.

     

    Now go to the step 7 again

    hope this time you will be successfully connected to your git repository.

    Now you have to configure Jenkins Envinment.

    • go to Manage jenkins ->configure system

    • Click on Grails Installation.

    • Add name of your grails version.(optional)

    • Add path of your grails SDK to Install directory field.

    • Click on JDK Installation.

    • Add name of your Java version.(optional).

    • Add path of your JDK to Install directory field.

    • now go to Git Plugin

    • Add your git user name to Global Config user.name Value field

    • Add your email id to Global Config user.email Value field.

    Click on save button. Now your jenkins is configured for your grails environment.

    step 8.

    • Now click on your project->configure

    • checked the check box Pull SCM under Build Triggers

    • Enter H/5 * * * *  in the field Schedule

    • Click on Add build step->Execute Shell.

    • Add your mechine specific setting in Command field to stop the server.

    • for example:

               sudo sh /home/shashikant/apache-tomcat-7.0.40/bin/shutdown.sh

    • Click on Add build step->Build with grails.

    • change grails installation Default to your grails version.

    • Add "war target/ROOT.war" to target field

    • Again Click on Add build step->Execute Shell.

    • Add your mechine specific setting in Command field.

    • For my machine its :

    sudo rm -rf /home/shashikant/apache-tomcat-7.0.40/webapps/ROOT*

    sudo mv /var/lib/jenkins/jobs/OodlesVid/workspace/target/ROOT.war /home/shashikant/apache-tomcat-7.0.40/webapps/

    sudo sh /home/shashikant/apache-tomcat-7.0.40/bin/startup.sh

    Click on save .Now your jenkins is Ready to use.
