Setting up Memcached on Plesk hosting control panel for your WordPress websites can be achieved by following these steps:

Step 1: Ensure Memcached Support First, make sure your Plesk hosting environment supports Memcached. Check if Memcached is available and supported by running the following command in the terminal or command prompt:

If you see a successful connection message, it means Memcached is installed and running.

Step 2: Install Memcached Extension (if needed) If Memcached is not installed, you can install it using the package manager for your server's operating system. For example, on CentOS/RHEL, use:

On Ubuntu/Debian, use:

Step 3: Enable Memcached in Plesk Login to your Plesk control panel and navigate to the server where you want to enable Memcached. Go to "Tools & Settings" > "Memcached Server (in the Additional Services section)".

Step 4: Configure Memcached in Plesk In the Memcached Server settings, you can configure the port, memory limit, and the number of connections. For example, set the port to 11211, the memory limit to 256MB, and the number of connections to 1024.

Step 5: Install Memcached PHP Extension Now, you need to install the Memcached PHP extension for your websites. Go to "Tools & Settings" > "PHP Settings", and click on the PHP version your WordPress website is using (e.g., PHP 7.4).

Scroll down to the "Additional PHP Directives" section, and add the following lines to enable the Memcached extension:

Step 6: Restart Apache/Nginx After making the changes, restart your web server (Apache or Nginx) for the PHP changes to take effect.

Step 7: Verify Memcached for WordPress To verify that Memcached is working for your WordPress websites, you can use a WordPress caching plugin that supports Memcached, such as "W3 Total Cache." Install and activate the plugin, then configure it to use Memcached as the caching method.

Once everything is set up correctly, your WordPress websites should now be utilizing Memcached for caching, which will help improve performance and speed.

Please note that while these steps provide general guidelines, specific server configurations and settings may vary. Always backup your website and server settings before making any changes and consider seeking assistance from a professional if you are unsure about any step in the process.

Hope it helps!
