WordPress Memcached

Using Memcached with WordPress

To use Memcached as a cache for your WordPress installation, follow these steps as described in the documentation of the Memcached Cloud plugin for WordPress:

1. Make sure that your WordPress server is installed with the libmemcached and the PECL memcached extension.
2. Copy the file object-cache.php from the Memcached Cloud plugin for WordPress .ZIP file to wp-content/object-cache.php of your WordPress installation.
3. Add the following definitions to your WordPress’ installation wp-config.php file:

    global $memcached_servers;
   $memcached_servers = array( array( 'hostname', port ) );
   
   global $memcached_username;
   $memcached_username = 'username';
   
   global $memcached_password;
   $memcached_password = 'password';
   

   • In line 3, the first argument should be your bucket’s hostname or IP address
   • In line 3, the second argument should be your bucket’s port
   • In line 5, the value should be your bucket’s username
   • In line 7, the value should be your bucket’s password
