Ruby is a popular object-oriented programming language that you can install and integrate with a cPanel & WHM system. For more information about the Ruby programming language, visit the Ruby website.


  • We deprecated Ruby on Rails in cPanel & WHM version 66. We strongly recommend that you install Ruby on your system via the following EasyApache 4 RPMs:
    • ea-ruby24-mod_passenger

    • ea-ruby24-ruby-devel
  • We also strongly recommend that you use cPanel's Application Manager interface (Home >> Software >> Application Manager) to manage Ruby applications.
  • For more information, read our How to Install Redmine documentation.


  • If you experience problems when you attempt to install Ruby, update your installation of YUM.
  • If you continue to experience problems after you update YUM, read the Troubleshoot your installation page.
  • We do not currently support Ruby on Rails installations on CentOS 7, CloudLinux™ 7, or Red Hat® Enterprise Linux® (RHEL) 7.
