We have partnered with Turnkey GNU/Linux, a free Debian based library of system images that pre-integrates and polishes the best free software components into secure, easy to use solutions.

Together you can rapidly deploy 100+ server applications to any of our SSD VPS hosting plans in just a few minutes. Just select an application image and watch it build. The server setup is handled, all you need to do is login to the application control panel and start using it. If you’re good with getting around control panels, running your own VPS is simple.

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.

Core Features:

• Base Operating System: Debian GNU.
• Secure and easy to maintain: Auto-updated daily with latest Debian security patches. Optional monitoring and email notification of system alerts.
• 1-click backup and restore: smart backup and data migration software saves changes to files, databases and package management to encrypted storage which a system can be automatically restored from.
• Dynamic DNS: Associates your IP with a custom domain.
• Logical Volume Management: 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 (Web CLI): secure command line access from any web browser.
• Web management interface (WebUI) (Webmin):
  • Listens on port 12321 (uses SSL).
  • Modern responsive theme: 'Authentic'.
  • 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 (note not proper interactive shell).
    • Simple file upload/download.
    • File manager (HTML5).
    • Custom commands.
  • Hardware modules:
    • Partitions on local disks.
    • Logical volume management.
• Simple configuration console (cli):
  • Displays basic usage information.
  • Configure networking.
  • Let's Encrypt SSL/TLS certificates.
  • Mail SMTP relay setup.
  • Proxy settings.
  • Region and timezone.
  • Other global system settings.
• 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.
• 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/python2.7/html
    exit
    # 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
