Web Application Framework

Ruby on Rails is an open-source web framework that's optimized for programmer happiness and sustainable productivity. Written in Ruby, Rails lets you write beautiful code by favoring convention over configuration. The result is a web framework that allows you to transition from idea to implementation in a very short period of time.

Stable version: 14.0 (changelog)

This appliance includes all the standard features in TurnKey Core, and on top of that:

  • SSL support out of the box.
  • Webmin modules for configuring Apache2, and MySQL.
  • Uses Ruby Enterprise for improved performance and memory utilization.
  • Ruby on Rails configuration:
    • Deployment via Phusion Passenger for Apache (mod_rails)
    • Preconfigured example Rails application located at /var/www/rails
    • MySQL databases setup for production, development and testing.
  • RubyGems package manager installed from upstream tarball
    • APT and RubyGems are both package management systems and may potentially conflict.
    • We recommend using RubyGems for managing Rails components (called gems), and APT for everything else.
    • Essential build packages (build-essentials) are included to aid in building gems.

Upgrading RubyGems itself and Rails components (gems):

gem update --system
gem update

See the Ruby on Rails docs for further details.
