How to Create Ruby Web Applications
Last modified: November 29, 2022
In cPanel & WHM version 66, we deprecated the legacy Ruby codebase and plan to remove it in a future release. This legacy Ruby codebase includes Ruby on Rails applications. We will not support any applications you create with the following interfaces:
cPanel’s Ruby on Rails interface (cPanel » Home » Software » Ruby on Rails).
cPanel’s RubyGems interface (cPanel » Home » Software » RubyGems).
The Ruby Gem installer feature in WHM’s Module Installers interface (WHM » Home » Software » Module Installers).
This document describes how to create and install Ruby web applications in cPanel & WHM version 66 and later that function on the Phusion Passenger® platform.
To use this feature, the cPanel account must possess compiler access in WHM’s Compiler Access interface (WHM » Home » Security Center » Compiler Access). If the account does not possess compiler access, the system will return an error similar to the following message:
make: execvp: gcc: Permission denied
Create a Ruby application
To install a Ruby application in cPanel & WHM version 66 and later, perform the following steps:
Install Ruby on your system. To do this, install the
ea-ruby27-mod_passengermodule in the Ruby via Passenger section of the EasyApache 4 interface (WHM » Home » Software » EasyApache 4).Note:
If you wish to add environment variables to your application, install the following additional RPMs:
For more information about environment variables, read cPanel’s Application Manager documentation.
Create a Ruby web application on your server. For examples of web applications that you can create, read the following documentation:
Use cPanel’s Application Manager interface (cPanel » Home » Software » Application Manager) to register the application.
