How to install the Memcached daemon for a user using ea-podman

Introduction

EasyApache 4 Containers allow for the secure deployment of the Memcached daemon on AlmaLinux, Rocky Linux, CloudLinux 8/9 or Ubuntu operating systems on a per-individual-cPanel-user basis.

Procedure

EasyApache 4 Podman Containers require a few base packages, and have specific user compatibility requirements. Please ensure you've completed all steps in this guide.

Base Packages

First, ensure the necessary packages are installed. The "ea-podman" repository must be installed and enabled, and the "ea-podman" and "ea-memcached" packages must be installed

1. Log into WHM.
2. Navigate to "WHM / Software / Install Distro Packages."
3. Search for "ea-podman" and ensure "ea-podman-repo" is installed.
4. Search for "ea-podman" and ensure "ea-podman" is installed.
5. Search for "ea-memcached" and ensure "ea-memcached16" is installed.

User Configuration

Next, you will need to ensure the cPanel user does not use CageFS or JailShell:

Create the Container

Then, access the shell, either via SSH or via cPanel / Terminal:

After logging into the cPanel user's command-line interface, install Memcached container:

/usr/local/cpanel/scripts/ea-podman install ea-memcached16

After you create the container, a directory with the container name is created that includes a Memcached socket file:

/home/$USER/ea-podman.d/container-name/memcached.sock

This socket file is the file you will direct your application to use as the Memcached location. If your application was previously configured to use an IP/domain and port, you should replace the port with port "0" and the path with:

unix:///home/$USER/ea-podman.d/container-name/memcached.sock
