Use memcached and the memcached extension to provide a backing store for the WordPress object cache.
This is forked from Memcached Object Cache to use Memcached instead of PECL Memcache
Memcached Object Cache provides a persistent backend for the WordPress object cache. A memcached server and the PECL memcache extension are required.
-
Install memcached on at least one server. Note the connection info. The default is
127.0.0.1:11211
. -
Install the memcached (not memcache) extension for PHP
-
Copy object-cache.php to wp-content
How can I manually specify the memcached server(s)?
Add something similar to the following to wp-config.php above /* That's all, stop editing! Happy blogging. */
:
$memcached_servers = array(
'default' => array(
'10.10.10.20:11211',
'10.10.10.30:11211'
)
);
The top level array keys, are cache groups, where 'default' corresponds to any cache group that is not explicitly defined. This allows for specifying memcached servers that only handle certain cache groups. The most common use is only specifying 'default'.
Possible cache groups are:
- {$taxonomy}_relationships
- {$meta_type}_meta
- {$taxonomy}_relationships
- blog-details
- blog-id-cache
- blog-lookup
- bookmark
- calendar
- category
- comment
- counts
- general
- global-posts
- options
- plugins
- post_ancestors
- post_meta
- posts
- rss
- site-lookup
- site-options
- site-transient
- terms
- themes
- timeinfo
- transient
- user_meta
- useremail
- userlogins
- usermeta
- users
- userslugs
- widget
