Setup Jenkins Environment on Ubuntu 13.04

jenkins-setup-ubuntu13.04

## Default setup: http://pkg.jenkins-ci.org/debian/

## Setup with oracle-jdk, mvn3, git, nginx and useful jenkins plugins

Remove OpenJDK first if installed by this command:
  sudo apt-get purge openjdk*

Then add the Webupd8 Team PPA repository and then reload the packages:
  sudo add-apt-repository ppa:webupd8team/java
  sudo apt-get update
  sudo apt-get install oracle-java6-installer // <6, 7, 8>

Installing maven 3
  sudo apt-get install maven

If you get the error:
  Errors were encountered while processing:
 /var/cache/apt/archives/libwagon2-java_2.2-3+nmu1_all.deb

Then a quick fix:
  sudo dpkg -i --force-all /var/cache/apt/archives/libwagon2-java_2.2-3+nmu1_all.deb

Installing NGINX
   sudo apt-get install nginx

  Setup reverse proxy:
    cd /etc/nginx/sites-available
    sudo rm default
    sudo vim /etc/nginx/nginx.conf
    
  Include the following content after 'include /etc/nginx/sites-enabled/*;':
        ##
        # Reverse proxy port 80 to port 8080 for Jenkins
        ##
        server {
                listen 80 default;
                server_name _;
                location /{
                        proxy_pass http://127.0.0.1:8080;
                }
        }


Installing Jenkins
  sudo apt-get install jenkins


Just in case you need to remove and install a new one
  sudo apt-get remove jenkins
  sudo apt-get purge jenkins
  Then I:
  
  sudo apt-get update
  sudo apt-get install jenkins


Adding Security
 Allow only logged in users to manage the system:
  Jenkins -> Manage Jenkins -> Configure Global Security. The check the box next to “Enable Security”. Under Access Control select “Jenkins’s own user database” Under Authorization select “Anyone can do anything” for now. Click on save.

  Once that’s enabled, go to Jenkins -> Manage Jenkins -> Manage Users. Create a user account and proceed to login with that username. Then navigate back to Jenkins -> Manage Jenkins -> Configure Global Security.
  user admin: all permissions;
  user anonymous: read only permissions;
  
  Under Access Control select “Matrix-based Security”. Create an entry for the user just created, then click on the little icon next to the red X,       which toggles all the checkboxes at once. Click save or apply.

Installing Git
  sudo apt-get install git
  git config --global user.name "Jenkins"
  git config --global user.email "jenkins@<yourdomain>"

  Setup GitHub
    sudo su jenkins
    ssh-keygen -t rsa
    (don't forget to let the passphrase empty)
    copy the content from 'cat /var/lib/jenkins/.ssh/id_rsa.pub' and add the key on github account.
    ssh [email protected] //to authenticate
      
  Jenkins -> Manage Jenkins:
    Set your SCM to Git and add your Repository URL and add an specific branch if you need.
