Memcached via Containers


Last modified: December 1, 2022

Overview

This document explains how to set up Memcached in an EasyApache 4 container. Memcached is a distributed memory-caching system. This document only applies to the EasyApache 4-provided Memcached package.

We provide Memcached version 1.6 for use with containers. You can only install container-based packages on systems that use EasyApache 4’s containers and run AlmaLinux OS 8, Rocky Linux™ 8, or Ubuntu®.

Note:
In this documentation, container-name represents the name of your Memcached container. You can find your containers’ names with either the registered or running options of the /usr/local/cpanel/scripts/ea-podman script.

Install Memcached via containers

To install Memcached in a container on a system that runs EasyApache 4, you must first set up EasyApache 4 containers on your system.

After you set up containers on your system, install the ea-memcached16 package to add Memcached to your system.

Set up Memcached inside containers

To set up Memcached to run inside a container, perform the following steps:

  1. Log in to the cPanel user account via SSH. You can do this using one of the following methods:
    • Log into the account via SSH from the command line.
    • Use SSH in either WHM’s Terminal interface (WHM » Home » Server Configuration » Terminal) or cPanel’s Terminal interface (cPanel » Home » Advanced » Terminal).
  2. Run the following command:
    /usr/local/cpanel/scripts/ea-podman install ea-memcached16
  3. Run the following command to retrieve the container’s name. You will need this name to perform any further actions.
    /usr/local/cpanel/scripts/ea-podman containers

For more information, read our /usr/local/cpanel/scripts/ea-podman script documentation.

Configure Memcached in a container

Note:
cPanel users must have shell access to configure Memcached in a container.

When you install Memcached into a container, it creates a directory in the ~/ea-podman.d/container-name directory in the user’s home directory. The system creates the memcache.sock socket when it sets up Memcached.

To use Memcached with your applications, direct your application to use the ~/container-name/memcache.sock socket.
