The following is how to set up an Upstart file so you can have a rails application autostart upon the startup of a server.

Modify the “USERNAME” and “TAG_FOR_THIS_PROCESS_IN_SYSLOG” fields to something that you want. It will run the server as the user you declare, so that the server isn’t run as the root user

If the process dies for any reason, Upstart will try to get it back up and running.

  # When to start the service

  # When to stop the service

  # Automatically restart process if crashed

  # Start the process

  chdir /home/USERNAME/learn_sorcery

  exec su -c '/home/USERNAME/.rbenv/shims/bundle exec rails s | logger -t TAG_FOR_THIS_PROCESS_IN_SYSLOG' USERNAME
