You can install the plugin from the WordPress plugin repository by searching for “Memcached Object Cache” or by downloading the plugin from the official WordPress plugin repository at https://wordpress.org/plugins/memcached/ and uploading it to your WordPress installation.
- Configure the plugin to use the Memcached server. You can find the configuration options for the plugin in the WordPress settings under “Settings” > “Memcached”. Enter the host and port for the Memcached server and save the changes.
