How to set up Redis on Ubuntu + OpenLitespeed + Wordpress?

Question

PHP

Colleagues, we need help. I installed redis for object caching, I did everything according to the instructions, the installation was ok, redis responds. But Wordpress writes Redis Disable. Then I went to study further, installed the Redis plugin for Wordpress, it turns out that this happens, nothing helped, anyway, in the WP admin panel it issues Redis Disable.

Help, friends, I'm already powerless to do something myself! I have Ubuntu 20, OpenLiteSpeed, PHP 7.3, Wordpress.

Here are the instructions for installing Redis:

Answer 1

Look here, everything is written how to check for php https://docs.litespeedtech.com/lscache/lscwp/admin... I
use the same bunch, I don’t remember which manual I did, but everything works fine.

Answer 2

Keep the third link to the collection - https://freelance.habr.com
But seriously - installation according to manuals regularly does not lead to good, because the one who uses them does not actually understand what he is doing. Hence the ninth wave of questions "friends, I did it according to these manuals, but it does not work," quite naturally cut out for the reason "this is a task, not a question."
