Testing Rails with Hudson CI

Written for Ubuntu LTS 10.4

Update and upgrade

  $ sudo aptitude update
  $ sudo aptitude upgrade

Install build-essential and friends

  $ sudo aptitude install build-essential zlib1g-dev libssl-dev libreadline5-dev openssh-server git-core

Hudson

Add Hudson package repo to sources.

Add the key:

  $ wget -O - http://hudson-ci.org/debian/hudson-ci.org.key | sudo apt-key add -

Add the repository to apt:

  $ sudo add-apt-repository 'deb http://hudson-ci.org/debian binary/'

Update apt and install Hudson:

  $ sudo aptitude update
  $ sudo aptitude install hudson

Install Nginx

sudo aptitude install nginx

Configure Nginx

Make Hudson available at a URL:

  $ sudo vim /usr/local/nginx/conf/nginx.conf

Then add this to the end of the file (but before the last '}'):

  # Hudson
  upstream hudson {
      server 127.0.0.1:8080;
  }

  server {
      server_name  ci.your-url.com; # replace this with the URL you want
                                    # Hudson to be available at
      root /var/lib/hudson;

      location / {
          proxy_pass http://hudson/;
          auth_basic "Hudson CI";
          auth_basic_user_file /var/opt/hudson/htpasswd;
     }

  }

Create a username and password (first you need apache2-utils):

  $ sudo apt-get install apache2-utils
  $ sudo mkdir -p /var/opt/hudson
  $ cd /var/opt/hudson
  $ sudo htpasswd -b -c htpasswd *username* *password*

Now visit http://ci.your-url.com and check you can log in with the username and password you set. You should see your Hudson instance running.

Configure Git & Github

Generate an ssh key-pair for the hudson user (create it in the default location and don't set a password):

  $ sudo su hudson
  $ ssh-keygen -t rsa -C "[email protected]"

Configure Git:

  $ git config --global user.email "[email protected]"
  $ git config --global user.name "Your Name"

Copy your ssh public key:

  $ su *your normal user*
  $ sudo apt-get install xclip
  $ sudo cat /var/lib/hudson/.ssh/id_rsa.pub | xclip -sel clip

And add it to your GitHub account.

Next, ssh to GitHub to authenticate:

  $ sudo su hudson
  $ ssh [email protected]

Configure Hudson

Visit http://ci.your-url.com
Follow to Manage Hudson > Manage Plugins and install any plugins you need (like Git).
Add a new project to test the system (something like FauxPass).
Add SCM details and build script.
Click Build Now.

Make Nginx allow GitHub to trigger builds in Hudson

(if you are currently the hudson user, switch back to your regular user now)

Open the nginx conf:

  $ sudo vim /etc/nginx/conf/nginx.conf

Add a second location with auth_basic turned off:

  location ~ /job/(.*)/build {
      auth_basic off;
      proxy_pass http://hudson;
  }

Then visit https://github.com/Username/project-name/edit?hooks=1 and add http://ci.your-url.com/job/*projectname*/build as a post-recive url.

Mysql

  $ sudo aptitude install mysql-server mysql-client libmysql-ruby libmysqlclient-dev
  $ sudo gem install mysql
