描述
Object caching backend using Redis for persistent storage. Implements all methods specified by WordPress Core. Supports multisite.
The plugin supports both the Redis PECL module and the Predis library to connect to Redis.
You must install the Redis server before using this plugin!
安装
- Install and configure Redis. There is a good tutorial here.
- Install the Redis PECL module or place the Predis library in the
/wp-content/predisdirectory. - Add
object-cache.phpto thewp-contentdirectory. It is a drop-in file, not a plugin, so it belongs in thewp-contentdirectory, not thepluginsdirectory. - By default, the script will connect to Redis at 127.0.0.1:6379. See the Connecting to Redis FAQ for further options.
常见问题
- Connecting to Redis
-
By default, the plugin uses
127.0.0.1and6379as the default host and port when creating a new client instance; the default database of0is also used. Three constants are provided to override these default values.Specify
WP_REDIS_BACKEND_HOST,WP_REDIS_BACKEND_PORT, andWP_REDIS_BACKEND_DBto set the necessary, non-default connection values for your Redis instance. - Prefixing Cache Keys
-
The constant
WP_CACHE_KEY_SALTis provided to add a prefix to all cache keys used by the plugin. If running two single instances of WordPress from the same Redis instance, this constant could be used to avoid overlap in cache keys. Note that special handling is not needed for WordPress Multisite.
