How to enable the Application Manager in cPanel

Introduction

How can I enable the Application Manager in my cPanel users' accounts?

Procedure

In order for the Application Manager to become available for a cPanel user to utilize it must first be enabled in the Feature Manager. 

Then you must install the following packages:

ea-ruby24-mod_passenger
ea-apache24-mod_env

Using the command line you can install both like this:

yum install ea-ruby24-mod_passenger ea-apache24-mod_env

NOTE: ea-ruby24-mod_passenger only works on systems that run CentOS 7. If your server is running AlmaLinux OS 8 or Rocky Linux™ 8, you will need to install ea-ruby27-mod_passenger.

For Ubuntu servers, you will also need to install the following packages:

ea-apache24-mod-passenger

This package can be installed in Ubuntu using apt as outlined below:

apt install ea-apache24-mod-passenger

After this is all complete, your cPanel users should have access to the Application Manager in their cPanel accounts.
