# Rails Continuous Integration Server Setup Notes
# This procedure was used to set up http://ci.rubyonrails.org on Ubuntu 8.04
# It can be used as a guideline for setting up your own CI server against your local rails branches

* Set up ci user:
# log in as root
$ adduser ci
enter user info and password
$ visudo
# give ci user same sudo rights as root

* Disable root login:
# log in as ci
$ sudo vi /etc/shadow
# overwrite and disable encrypted root password to disable root login:
root:*:14001:0:99999:7:::

* Change Hostname:
$ sudo vi /etc/hostname
change to correct hostname
$ sudo vi /etc/hosts
replace old hostname with the correct hostname
# reboot to use new hostname (and test reboot)
$ sudo shutdown -r now

* Update aptitude:
$ sudo aptitude update

* Use cinabox to perform rest of ruby/ccrb setup: 
* http://github.com/thewoolleyman/cinabox/tree/master/README.txt

# This is not yet properly supported by RubyGems...
# * Configure RubyGems to not require root access for gem installation
# $ vi ~/.profile
# # add this line at bottom:
# PATH="$HOME/.gem/ruby/1.8/bin:$PATH"
# $ sudo vi /etc/init.d/cruise
# # edit the start_cruise line to source CRUISE_USER/.profile:
#   start_cruise "cd #{CRUISE_HOME} && source /home/#{CRUISE_USER}/.profile && ./cruise start -d"
# $ vi ~/.gemrc
# # add these lines:
# ---
# gemhome: /home/ci/.gem/ruby/1.8
# gempath: 
# - /home/ci/.gem/ruby/1.8

* If you did not configure no-root-gem installation via ~/.gemrc as shown above, then allow no-password sudo for gem installation:
$ sudo visudo
# add this line to bottom:
ci      ALL=(ALL) NOPASSWD: ALL

* Start ccrb via init script and check for default homepage at port 3333

* Install/setup nginx:
$ sudo aptitude install nginx
$ sudo vi /etc/nginx/sites-available/default
# Add the following entry at the top of the file above the 'server {' line:
upstream mongrel {
  server 127.0.0.1:3333;
}

# Change server_name entry to match server name

# replace the contents of the root 'location / {}' block with the following entries:
    proxy_pass          http://mongrel;
    proxy_redirect      off;
    proxy_set_header    Host             $host;
    proxy_set_header    X-Real-IP        $remote_addr;
    proxy_set_header    X-Forwarded-For  $proxy_add_x_forwarded_for;
    proxy_set_header    X-Client-Verify  SUCCESS;
    proxy_read_timeout  65;

# also comment default locations for /doc and /images
$ sudo /etc/init.d/nginx start

* Add project to cruise (It will still fail until everything is set up):
$ cd ~/ccrb
$ ./cruise add rails -s git -r git://github.com/rails/rails.git  # or the URI of your branch

* Copy and configure cruise site config file:
$ cp ~/.cruise/projects/rails/work/ci/site_config.rb ~/.cruise/site_config.rb
# Edit ~/.cruise/site_config.rb as desired, for example:
ActionMailer::Base.smtp_settings = {
  :address =>        "localhost",
  :domain =>         "ci.yourdomain.com",
}
Configuration.dashboard_refresh_interval = 60.seconds
Configuration.dashboard_url = 'http://ci.yourdomain.com/'
Configuration.serialize_builds = true
Configuration.serialized_build_timeout = 1.hours
BuildReaper.number_of_builds_to_keep = 100
  
* Copy and configure cruise project config file
$ cp ~/.cruise/projects/rails/work/ci/cruise_config.rb ~/.cruise/projects/rails
$ vi ~/.cruise/projects/rails/cruise_config.rb:
# Edit ~/.cruise/projects/rails/cruise_config.rb as desired, for example:
Project.configure do |project|
 project.build_command = 'ruby ci/ci_build.rb'
 project.email_notifier.emails = ['recipient@yourdomain.com']
 project.email_notifier.from = 'sender@yourdomain.com'
end

* Set up mysql
$ sudo aptitude install mysql-server-5.0 libmysqlclient-dev
# no password for mysql root user

* setup sqlite
$ sudo aptitude install sqlite sqlite3 libsqlite-dev libsqlite3-dev
# Note: there's some installation bugs with sqlite3-ruby 1.2.2 gem file permissions:
#   http://www.icoretech.org/2008/07/06/no-such-file-to-load-sqlite3-database
#   cd /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.2 && sudo find . -perm 0662 -exec chmod 664 {} \;

* setup postgres
$ sudo aptitude install postgresql postgresql-server-dev-8.3
$ sudo su - postgres -c 'createuser -s ci'

* Install fcgi libraries
$ sudo apt-get install libfcgi-dev

* Install memcached and start for first time (should start on reboot automatically)
$ sudo aptitude install memcached
$ sudo /etc/init.d/memcached start

* Install and run GemInstaller to get all dependency gems
$ sudo gem install geminstaller
$ cd ~/.cruise/projects/rails/work
$ sudo geminstaller --config=ci/geminstaller.yml # turn up debugging with these options: --geminstaller-output=all --rubygems-output=all

* Create ActiveRecord test databases for mysql
$ mysql -uroot -e 'grant all on *.* to rails@localhost;'
$ mysql -urails -e 'create database activerecord_unittest;'
$ mysql -urails -e 'create database activerecord_unittest2;'

* Create ActiveRecord test databases for postgres
# cd to rails activerecord dir
$ rake postgresql:build_databases

* Reboot and make sure everything is working
$ sudo shutdown -r now
$ http://ci.yourdomain.com
