Redis can be effectively used in optimizing site performance. However, please note that Redis is not provided by cPanel directly, and thus its use is the sole responsibility of the server administrator.
We want everyone who uses cPanel to have an amazing experience, both with our software and our support. Sometimes that means pointing you to an expert or external resource about your particular problem if it is not a cPanel-related issue or if the external resource will better address your reported issue.
The installation of Redis has two main parts: the Redis service itself and the PHP extension to allow scripts to access and utilize the service. Installing the service requires enabling of an additional repository, and the PHP Extention will need to be installed using PECL for each PHP version.
For details, there are various 3rd-party guides available online, which can be quite helpful in this process. One such guide, for which we've received positive feedback, can be found at:

Use of software not provided by or managed by cPanel, or 3rd-party guides is solely at the administrator's discretion. We strongly encourage you to test them extensively on a development/test server before deploying this into production.
