Ruby on Rails - 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.

Ruby on Rails

Core Features:

  • Base distribution: TurnKey 12.1 based on Debian 6.0.7 (Squeeze), TurnKey 13 based on Debian 7.1 (Wheezy)
  • Smart backups (TKLBAM): automated backup and restore, with system migration capabilities
  • Secure and easy to maintain: auto-updated daily with latest security patches
  • Dynamic DNS (hubdns): associates your IP with a custom domain or the free * domain
  • Logical Volume Management (LVM): instead of installing to a fixed size partition, a Logical Volume is first created by default, and this may later be expanded, even across multiple physical devices
  • AJAX web shell (shellinabox) - secure command line access from any web browser
  • Web management interface (Webmin)
    • Listens on port 12321 (uses SSL)
    • Mac OS X themed
    • Network modules
      • Firewall configuration (with example configuration)
      • Network configuration
    • System modules
      • Backup and migration (TKLBAM)
      • Configure time, date and timezone
      • Configure users and groups
      • Manage software packages
      • Change passwords
      • System logs
    • Tool modules
      • Text editor
      • Shell commands
      • Simple file upload/download
      • File manager (needs support for Java in browser)
      • Custom commands
    • Hardware modules
      • Partitions on local disks
      • Logical volume management
  • Simple configuration console (confconsole)
    • Displays basic usage information
    • Configure networking
  • First boot initialization
    • Prompt user for passwords
    • Regenerates SSL and SSH cryptographic keys
    • Installs latest security updates, unless user chooses to defer this for later
    • Uses GeoIP to automatically configure closest APT package archive for maximum network performance
  • Command line power tools
    • Smart, programmable bash shell completion: helps you get more done with fewer keystrokes.
    • Support for $HOME/.bashrc.d shell hooks
    • Persistent environment variables (see $HOME/.bashrc.d/penv):
penv-set pydoc /usr/share/doc/python2.6/html

# later...
cd $pydoc
  • Automatic time synchronization with NTP

Distribution Features:

  • 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/railsapp
    • 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.

Credentials (passwords set at first boot)
