Supports [Predis](https://github.com/nrk/predis/), [PhpRedis (PECL)](https://github.com/phpredis/phpredis), [HHVM](https://github.com/facebook/hhvm/tree/master/hphp/system/php/redis), replication, clustering and [WP-CLI](http://wp-cli.org/). Forked from Eric Mann's and Erick Hitter's [Redis Object Cache](https://github.com/ericmann/Redis-Object-Cache). And forked again from Till Krüss's [Redis Cache](https://github.com/tillkruss/redis-cache). We wanted to have only the `object-cache.php` dropin file and nothing else. Installation ------------ [](#installation) ``` $ composer require devgeniem/wp-redis-object-cache-dropin ``` Connection Parameters --------------------- [](#connection-parameters) By default the object cache drop-in will connect to Redis over TCP at `127.0.0.1:6379` and select database `0`. To adjust the connection parameters, define any of the following constants in your `wp-config.php` file. - `WP_REDIS_CLIENT` (default: *not set*) Specifies the client used to communicate with Redis. Supports `hhvm`, `pecl` and `predis`. - `WP_REDIS_SCHEME` (default: `tcp`) Specifies the protocol used to communicate with an instance of Redis. Internally the client uses the connection class associated to the specified connection scheme. Supports `tcp` (TCP/IP), `unix` (UNIX domain sockets), `tls` (transport layer security) or `http` (HTTP protocol through Webdis). - `WP_REDIS_HOST` (default: `127.0.0.1`) IP or hostname of the target server. This is ignored when connecting to Redis using UNIX domain sockets. - `WP_REDIS_PORT` (default: `6379`) TCP/IP port of the target server. This is ignored when connecting to Redis using UNIX domain sockets. - `WP_REDIS_PATH` (default: *not set*) Path of the UNIX domain socket file used when connecting to Redis using UNIX domain sockets. - `WP_REDIS_DATABASE` (default: `0`) Accepts a numeric value that is used to automatically select a logical database with the `SELECT` command. - `WP_REDIS_PASSWORD` (default: *not set*) Accepts a value used to authenticate with a Redis server protected by password with the `AUTH` command. Configuration Parameters ------------------------ [](#configuration-parameters) To adjust the configuration, define any of the following constants in your `wp-config.php` file. - `WP_CACHE_KEY_SALT` (default: not set) Set the prefix for all cache keys. Useful in setups where multiple installs share a common `wp-config.php` or `$table_prefix`, to guarantee uniqueness of cache keys. - `WP_REDIS_MAXTTL` (default: *not set*) Set maximum time-to-live (in seconds) for cache keys with an expiration time of `0`. - `WP_REDIS_GLOBAL_GROUPS` (default: `['blog-details', 'blog-id-cache', 'blog-lookup', 'global-posts', 'networks', 'rss', 'sites', 'site-details', 'site-lookup', 'site-options', 'site-transient', 'users', 'useremail', 'userlogins', 'usermeta', 'user_meta', 'userslugs']`) Set the list of network-wide cache groups that should not be prefixed with the blog-id *(Multisite only)*. - `WP_REDIS_IGNORED_GROUPS` (default: `['counts', 'plugins']`) Set the cache groups that should not be cached in Redis. Replication & Clustering ---------------------------- [](#replication--clustering) To use Replication and Clustering, make sure your server is running PHP7, your setup is using Predis to connect to Redis and you consulted the [Predis documentation](https://github.com/nrk/predis). For replication use the `WP_REDIS_SERVERS` constant and for clustering the `WP_REDIS_CLUSTER` constant. You can use a named array or an URI string to specify the parameters. For authentication use the `WP_REDIS_PASSWORD` constant. ### Master-Slave Replication [](#master-slave-replication) ``` define( 'WP_REDIS_SERVERS', [ 'tcp://127.0.0.1:6379?database=15&alias=master', 'tcp://127.0.0.2:6379?database=15&alias=slave-01', ] ); ``` ### Clustering via Client-side Sharding [](#clustering-via-client-side-sharding) ``` define( 'WP_REDIS_CLUSTER', [ 'tcp://127.0.0.1:6379?database=15&alias=node-01', 'tcp://127.0.0.2:6379?database=15&alias=node-02', ] ); ``` Maintainers ----------- [](#maintainers) [@onnimonni](https://github.com/onnimonni) [@villepietarinen](https://github.com/villepietarinen) ### Health Score 38 — LowBetter than 83% of packages Maintenance13 Infrequent updates — may be unmaintained Popularity32 Limited adoption so far Community23 Small or concentrated contributor base Maturity72 Established project with proven stability Bus Factor1 Top contributor holds 82.8% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
