Recommended memcached installation method for multi-user support
Hi, I've got a server with about 9 or 10 wordpress installations; looking at memcached as an object caching solution but still a little unclear on the proper method of installation.
The goal is to have memcached working for all of the wordpress based user accounts. From what I can tell it sounds like there are at least a couple of different methods of installing memcached on Almalinux8. It looks like I could install it directly on the server, or through podman with containers.
If I go with the container approach, it sounds like I would need to first setup

It's pretty easy to install memcached. Run the following command as root: yum -y install memcached Then use EA4 to install the phpXX-php-memcached PHP modules for the PHP versions you need it. 0 -
Awesome, thank you @ResellerWiz! That is definitely easy enough lol, looks like the method for installing server wide. I guess I'm trying to figure out if there is any built in security with this option that would prevent memory leaks between user accounts and to control how much memory us available per user. 0 -
Thank you @cPRex, that blog post confirmed exactly what I was worried about. Specifically this: [QUOTE]Before we begin, a word of warning: the method outlined here should only be used on single-tenant dedicated servers, such as cPanel solo and virtual server hosting. It is not suitable for multi-tenant shared hosting environments without additional configuration to enable authentication or encryption.
it's really starting to sound like the best option for a multi-user / multi-tenant setup is to install EasyApache 4 Containers (ea-podman) and use memcached (ea-memcached16) as a socket inside the container. This way each user has it's own version of memcached which is isolated by the socket inside the container registered to that user account. So. I'm thinking the install would look something like this: Install EasyApache 4 Container package on the root server:dnf install ea-podman-repo dnf install ea-podman dnf install ea-tomcat100
Login to each user account via ssh and install EA4 memcached package into the users container:/usr/local/cpanel/scripts/ea-podman install ea-memcached16
Get the container name:/usr/local/cpanel/scripts/ea-podman containers
Figure out how to get wordpress to recognize the new socket: To use Memcached with your applications, direct your application to use the ~/container-name/memcache.sock socket. Does this sound about right?0 -
That all does sound right to me, although I still think you'd have more CPU and RAM control with CloudLinux. 0 -

Agreed. Was going to suggest CloudLinux as well.0 -
Jumping in to ask a question: [QUOTE]Before we begin, a word of warning: the method outlined here should only be used on single-tenant dedicated servers, such as cPanel solo and virtual server hosting. It is not suitable for multi-tenant shared hosting environments without additional configuration to enable authentication or encryption.
Why is it not suitable for a shared server? I thought the whole point of memcached was to try to reduce server resources being used - and that's typical of a shared server. [QUOTE]...

I'd like to install on my test server and have a play: So where can I find out the additional configuration needed to enable operation on a shared server?0 -
Thanks @cPRex @SimpleTechGuy - Can you share which path you have taken? I'm keen to explore a server side caching solution for WP. 0
