Store WordPress session tokens in Redis rather than the usermeta table.

Description

Store WordPress user session tokens in Redis rather than the usermeta table.

This plugin was previously known as WP Redis User Session Storage and was renamed to comply with WordPress.org naming constraints.

Installation

1. Install and configure Redis.
2. Install the Redis PECL module.
3. Activate the plugin network-wide or by placing it in mu-plugins.
4. By default, the script will connect to Redis at 127.0.0.1:6379. See the Connecting to Redis section for further options.

Frequently Asked Questions

Connecting to Redis

By default, the plugin uses 127.0.0.1 and 6379 as the default host and port, respectively, when creating a new client instance; the default database of 0 is also used.

Specify any of the following constants to set the necessary, non-default connection values for your Redis instance:

• WP_REDIS_USER_SESSION_HOST - Hostname or IP of the Redis server, defaults to 127.0.0.1.
• WP_REDIS_USER_SESSION_PORT - Port of the Redis server, defaults to 6379.
• WP_REDIS_USER_SESSION_SOCKET - Path to a Unix socket file for the Redis server, if available. Takes precedence over the port value when set.
• WP_REDIS_USER_SESSION_AUTH - Password for the Redis server, if required.
• WP_REDIS_USER_SESSION_DB - Database number to use for the Redis server, defaults to 0.
• WP_REDIS_USER_SESSION_SERIALIZER - Serializer to use for the Redis server, defaults to Redis::SERIALIZER_PHP.

How do I upgrade from WP Redis User Session Storage?

Install and activate this plugin, then deactivate the old plugin. Both plugins can safely be activated together as long as no additional classes extend the WP_Redis_User_Session_Storage class. After activating this plugin, deactivate the WP Redis User Session Storage plugin and remove it.
