The RoR module manages Ruby on Rails®.


  • We deprecated the legacy Ruby codebase in cPanel & WHM version 66. For more information, read our cPanel Deprecation Plan documentation.
    • To install Ruby and create Ruby web applications in cPanel & WHM version 66 and later, follow the directions in our How to Create Ruby Web Applications documentation.
    • To register and manage Ruby applications that you create in WHM version 66 and later, use the functions in UAPI PassengerApps module functions.


In cPanel & WHM version 76, we introduced server profiles and roles. When you enable a non-Standard Node server profile, the system disables API calls associated with that profile's disabled roles.
