Latest Object Cache Pro Download (Formerly known as Redis Object Cache Pro) This is an enterprise-grade object caching plugin designed for WordPress to improve site performance. Using Redis to cache objects in WordPress (such as posts, pages, comments, taxonomies, etc.) into memory reduces the number of database queries, which greatly improves page load speed,Responsiveness.
It also improves the speed of access to the backend, the frontend search function, filtering function and so on. Especially for Woocommerce sites that have to deal with a lot of dynamic content and high traffic, using a caching plugin like Redis Object Cache Pro is very beneficial.However, it may not be very helpful for static sites, which tend to involve few database queries, so the object store is of limited use.
Redis Object Cache Pro is an object cache that can be used in conjunction with theNginx-FastcgiThe system cache as well as theWp Rocketand other page caching plug-ins to use together, because they cache the target as well as the role of different levels. However, the use of multiple caches together need to be configured, otherwise it is easy to duplicate the cache resulting in slow speed or conflict.
It can also cache some background operations to speed up background access. If the background made some changes did not take effect in time, refresh the Redis cache can be.
Use this plugin to achieve Redis object cache can no longer use Mamcached object cache , the site can only use an object cache . After the use of object caching, there is no need to use the database cache, easy to have conflicts.

The server PHP needs to have the Redis extension installed firstThen copy and paste the following configuration code (choose one of the two codes) into the root directory of the website wp-config.php, go back to the plugin settings page and click "Enable Cache" to enable it.
Note that all the lines of the following code have a comma at the end of the parameter setting line , . If the request data is visible in the Redis Object Cache Pro dashboard, the configuration is successful.
Small and medium-sized websites, especially foreign trade websites, use the following configuration.
define('WP_REDIS_CONFIG', [
'token' => 'e279430effe043b8c17d3f3c751c4c0846bc70c97f0eaaea766b4079001c',
'host' => '127.0.0.1',
'database' => 0, // 0 for the first site, 1 for the second, and so on
'maxttl' => 3600 * 24 * 7, // 7 days
'timeout' => 1.0, /> 'read_timeout' => 1.0, // 1.0, // 7 days
'read_timeout' => 1.0, // 7 days 'timeout' => 1.0, // 1.0, // 7 days
'prefetch' => true, 'split_alloptions' => 1.0
'split_alloptions' => true, 'strict' => true, // 7 days
'debug' => false, .
]);
define('WP_REDIS_DISABLED', false);For high-performance sites and large sites, use the following configuration.Caution.'compression' => 'zstd' and 'serializer' => 'igbinary' These 2 elements require the zstd and igbinaryPHP extensions to be installed first, and restarted after installation.
If you add the code after the site prompts "Error establishing a Redis connection", delete these 2 contents, save and restart PHP site recovery. Pagoda panel installation of these 2 extensions are not compiled into Phpredis, so it can not be used.
define('WP_REDIS_CONFIG', [
'token' => 'e279430effe043b8c17d3f3c751c4c0846bc70c97f0eaaea766b4079001c',
'host' => '127.0.0.1',
'database' => 0, // 0 for the first site, 1 for the second, and so on
'timeout' => 0.5, // the first site is 0, the second is 1, and so on.
'read_timeout' => 0.5,
'retry_interval' => 10, 'retries' => 3, // the first site is 0, the second is 1, and so on.
'retries' => 3, 'backoff' => 'smart', and so on.
'compression' => 'zstd', // `zstd` compresses smaller, `lz4` compresses faster
'serializer' => 'igbinary', 'async_flush'
'split_alloptions' => true, 'prefetch' => true, `split_alloptions' => true, `lz4` compresses faster
'debug' => false, 'save_commands' => true
'save_commands' => false, .
]).
define('WP_REDIS_DISABLED', getenv('WP_REDIS_DISABLED') ? : false);host' => Specify the Redis server address, or '127.0.0.1' if it is on the same host as the WEB server.
'port' => Redis connection port, the default is 6379, if you change the default port in Redis, then this should follow.
'database' => Specify the Redis database number. If there are multiple sites using the same Redis server, you need to specify a different database number for each site. The default is 0. The maximum number of numbers supported depends on the number of databases supported by the Redis server, which by default supports 16.
Tip: If you have more than one website inside your server using this plugin, you need to set 'database' => 0 for the first website, 'database' => 1 for the second, and so on. Otherwise the site will be abnormal.
'username' => Specifies the username of the connection. If Redis does not set login authentication, this parameter is not required. Example usage: 'username' => 'abc',
'password' => Specify the password for the connection, used as above.
'prefix' => Similar to WP's $able_prefix variable, which adds a prefix to all database table names. Example: 'prefix' => 'mysitename',
'maxttl' => enforce "maximum time to live" in seconds for all new cache keys. Example: 'maxttl' => 3600 * 24, // 24 hours
'timeout' => connection timeout with Redis, in seconds, supports decimals. Example: 'timeout' => 1.5,
'read_timeout' => read timeout in seconds, decimals supported, same usage as above.
'retry_interval' => retry interval, in milliseconds, integer supported. Example: 'retry_interval' => 300,
'retries' => Set the number of retries for a failed connection, integer type.
'backoff' => 'default', when using the retry configuration, the default backoff configuration will be used, which includes: a de-correlated jitter algorithm, a base of 500 ms for compensation calculation, and a compensation time limit of 750 ms
'shared' => true, sets whether the Redis server/cluster is shared or dedicated. This affects how memory and key counts are displayed.
'async_flush' => true, Asynchronous flush was introduced in Redis 4.0 and can be enabled using this async_flush option. It allows deleting a large number of Keys in the background without blocking the server.
'prefetch' => true, When prefetching is enabled, the requested cached keys are stored on a per-request basis and are loaded in bulk by group early in successive requests. The list of prefetchable keys is updated on each request to keep it up to date.
'split_alloptions' => true: Store alloptions keys as a hash in Redis instead of a single serialized string. This can improve performance and reduce memory usage.
The following 2 settings should be careful, how to add and then link the database failure or site anomaly, please delete.
'serializer' => 'igbinary': can improve the processing speed of cached data and reduce the memory usage of cached data. However, igbinary compatibility is almost close, and site anomalies may occur after enabling it.
'compression' => 'zstd': set compression algorithm, further less data size. However, zstd compatibility is not so good, and there may be site anomalies after enabling it.
The above are some common parameters, basically meet most of the website needs, such as the need to understand all the parameters please checkOfficial Documents.
For advanced features such as compression and asynchronous refresh, please seeConfiguration OptionsThe full list of To connect to a Redis cluster or use replication, seeConnection Guide.
