pound and mongrel_cluster

In order to easily manage the development/deployment via Capistrano, it made sense to also be running mongrel_cluster automatically. This way deployment is real-time with instant results.

gem install mongrel_cluster capistrano --include-dependencies

Then install pound via emerge/yast. Edit the pound.cfg file:
(this still doesn't seem to be working)

ListenHTTP
  Address 0.0.0.0
  Port    80
  Service
    BackEnd
      Address 0.0.0.0
      Port    8000
    End
    BackEnd
      Address 0.0.0.0
      Port    8001
    End
    BackEnd
      Address 0.0.0.0
      Port    8002
    End
    Session
      Type BASIC
      TTL  300
    End
  End
End

Start pound and add it to startup:

/etc/init.d/pound start
rc-update add pound default

Next, railsapp/config/mongrel_cluster.yml would look like:

cwd: /home/build/deploy/current
port: "8000"
environment: development
address: 0.0.0.0
pid_file: log/mongrel.pid
servers: 3

Initialize capistrano for railsapp:

cap --apply-to /path/to/railsapp MyApplicationName

Now that capistrano has been initialized, update the config/deploy.rb file adding:

set :mongrel_conf, "#{current_path}/config/mongrel_cluster.yml"

Update the other properties as necessary, paying particular attention to:

role :web, "someserver.yourinternaldomain.local"

The servers will have to be contactable by the exact name placed in the quotes.

Update the remote variables:

set :deploy_to, "/home/build/deploy"
set :user, "build"
set :keep_releases, 5

Be sure to have the "build" user's password on hand since it'll be necessary for capistrano commands.

Ensure capistrano is working with:

rake remote:exec ACTION=setup

Check that the target server has the releases and shared directories created, if so, capistrano worked.

Lastly:

rake deploy

This should pull everything down and place it in the "current" directory (in relation to cwd).

Create a link to mongrel_cluster script and mongrel_cluster.yml then add to startup:

mkdir /etc/mongrel_cluster
ln -s /home/build/deploy/current/config/mongrel_cluster.yml /etc/mongrel_cluster/railsapp.yml
ln -s /usr/lib/ruby/gems/1.8/gems/mongrel_cluster-0.1.3/resources/mongrel_cluster /etc/init.d/mongrel_cluster
chmod +x /etc/init.d/mongrel_cluster
rc-update /etc/init.d/mongrel_cluster default

TODO: autostart failing on Gentoo

Lastly, start the mongrels:

/etc/init.d/mongrel_cluster start

Test from port 80, 8000, 8001 and 8002 that the rails intro page comes up. Done.
