Mongrel Startup Script

I couldn't find one that did exactly what I wanted, so I cooked up this ruby script. Be sure to change app_dir and apps near the top to match your environment. On my ubuntu/debian server, this script resides in /etc/init.d. I ran "sudo update-rc.d -f mongrel defaults" to make it run on startup.

apps = {

  'hpy' => 8001,

}



if ['stop', 'restart'].include? ARGV.first

  apps.each do |path, port|

    path = File.join app_dir, path

    puts "Stopping #{path}..."

    `mongrel_rails stop -c #{path} -P log/mongrel.pid`

  end
