Redis is an open source, in-memory, key-value data store most commonly used as a primary database, cache, message broker, and queue. Redis delivers sub-millisecond response times, enabling fast and powerful real-time applications<\/p>\n\n\n\n

Redis Object Cache is a persistent object cache backend powered by Redis. Supports Predis, PhpRedis, Relay, replication, sentinels, clustering and WP-CLI.For a faster cache plugin.<\/p>\n\n\n\n

What this means is that we can increase performance for your cPanel WordPress Site.<\/p>\n\n\n\n\n\n\n\n

Now, first install Redis<\/p>\n\n\n\n

Install Epel<\/p>\n\n\n

\n yum install epel-release\n<\/pre><\/div>\n\n\n
Install Redis Server<\/p>\n\n\n
\nyum install redis\n<\/pre><\/div>\n\n\n
After successfully installation start the Redis service and enable to auto-start on system reboot.<\/p>\n\n\n\n

CLI Install<\/p>\n\n\n\n
Here are examples on CLI install.<\/p>\n\n\n\n
PHP 8.0<\/p>\n\n\n
\n\/opt\/cpanel\/ea-php80\/root\/usr\/bin\/pecl install igbinary igbinary-devel redis\n<\/pre><\/div>\n\n\n
Output:<\/p>\n\n\n\n
You will see a choice for the following. Just hit Enter.<\/p>\n\n\n
\nenable igbinary serializer support? [no] :\nenable lzf compression support? [no] :\nenable zstd compression support? [no] :\n<\/pre><\/div>\n\n\n
The install completes.<\/p>\n\n\n

You can install to any PHP, just use the correct path.<\/p>\n\n\n\n
Next, install and Activate the Redis Object Cache plugin via the WordPress Dashboard.<\/p>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
Configuring the plugin<\/p>\n\n\n\n
After installing and activating the plugin, go to WordPress -> Settings -> Redis and enable the cache and check if the plugin can connect automatically.<\/p>\n\n\n\n
By default the object cache will connect to Redis Server over TCP at 127.0.0.1:6379.<\/p>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
You should see the following:<\/p>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
Edit the wp-config.php for each site. <\/p>\n\n\n\n
When editing your wp-config.php file, it is important that WP_REDIS_* constants are defined high up in the file, above these lines:<\/p>\n\n\n
\n\/* That's all, stop editing! Happy publishing. *\/\nrequire_once(ABSPATH . 'wp-settings.php');\n<\/pre><\/div>\n\n\n
Here is a good starting point.<\/p>\n\n\n
\nnano wp-config.php\n<\/pre><\/div>\n\n
\n\/\/ adjust Redis host and port if necessary \ndefine( 'WP_REDIS_HOST', '127.0.0.1' );\ndefine( 'WP_REDIS_PORT', 6379 );\n\n\/\/ change the prefix and database for each site to avoid cache data collisions\ndefine( 'WP_REDIS_PREFIX', 'my-site' );\ndefine( 'WP_REDIS_DATABASE', 0 ); \/\/ 0-15\n\n\/\/ reasonable connection and read+write timeouts\ndefine( 'WP_REDIS_TIMEOUT', 1 );\ndefine( 'WP_REDIS_READ_TIMEOUT', 1 );\n<\/pre><\/div>\n\n\n
Check it in the WordPress Dashboard<\/p>\n\n\n\n
