Memcached Object Cache for wordpress

Installation

  1. Install memcached on at least one server. Note the connection info. The default is 127.0.0.1:11211.
  2. Install the PECL memcache extension
  3. Copy object-cache.php to wp-content
  4. Add the WP_CACHE_KEY_SALT constant to the wp-config.php:

    php
    define('WP_CACHE_KEY_SALT', '...long random string...');

This helps prevent cache pollution when multiplte WordPress installs are using the same Memcached server. The value must be unique for each WordPress install.
