How do I install and enable Apache and PHP modules on my cPanel VPS?
By default, cPanel/WHM is bundled with EasyApache.
EasyApache is a useful piece of software that allows you to reconfigure Apache and PHP.
For example, you may want to install a particular PHP module, that isn't enabled by default. EasyApache provides an easy GUI-based method to do so.
To use EasyApache, you will first need to log in to the Unmanaged VPS via either option in the control panel, or manually via the VPS hostname.
Once logged in, under Software, select the EasyApache icon.
From this point, select Customize. You'll then be able to customize your Apache/PHP configuration, and select the modules/configuration that you need.
