Configure memcached and redis

I got working openlitespeed vm and installed all lsphp73-* packages where are also "lsphp73-mecached" and "lsphp73-redis" but I just installed "memcached" started and in WordPress Litespeed Cache plugin it shows that it's working with localhost set. Is there need for lsphp packages? Any advantages and how I can start lsphp73-memcached service? I'm bit newbie, so I'll appreciate any information.


Yes, lsphp-xx package is a must for object cache but you don't need to config anything on it.
You can create a phpinfo page see if php extension already installed.
