Automatic Production Rails

Welcome to the second FiveRuns blog post to automate server configuration for Ruby on Rails. We received great feedback and suggestions about the original script, Automatic Rails at Slicehost, which installed the basics. This time we’ll use standards like Capistrano deployment, separate web and application layers and an active database backend. While the Hello World application surely dazzled your friends and family, this time we’ll take it up a notch and deploy a working, full stack community web application, Trevor Turk’s cool Rails app, Eldorado.

The What

This script connects to a new Ubuntu 8.04 server and configures all necessary applications and libraries. Since we are installing a lot more this time, it’s a bit long to post here, so I’ve linked to it on Github. You still only need to provide 2 pieces of information: the target address of your server and the password. Execute the script locally which downloads Eldorado, the associated configuration files and then connects to your server to push the installation.

The previous script installed:

  • Ruby 1.8.6
  • Rubygems 1.2
  • Sqlite3
  • MySQL 5.0.51a
  • Thin 0.8.2
  • Hello World example Rails application

This time we use:

  • nginx 0.5.33
  • Mongrel 1.1.5
  • Eldorado Rails application
  • Capistrano deployment
  • Rubygems 1.3

The How

1. Download the script from Github. I’ve abbreviated the URL.

wget -O

2. Run the script.


That’s it! You’ll be asked for your password twice, once to set up the OS via ssh and once to run the Capistrano deployment tasks. Speaking of passwords, best practices include dedicated deployment and MySQL user accounts. This script uses the root account for simplicity.

The Why

The script originated as a DRY effort for Slicehost deployments. You can now point it at other providers, remote Ubuntu servers or virtual machines. It’s become a handy way to explore a working Rails environment without manually installing every component. Also, writing configuration automation is a great way to hone your deployment skills. Thanks go to Trotter Cashion for the suggestion to maintain the scripts on Github, where they’ve been forked and extended. Check out Jørgen Orehøj Erichsen’s blog adding support for Passenger and Ruby Enterprise Edition.

All the scripts and configuration files are on Github so feel free to post any feedback or suggestions.
