What is Redis?
Redis is an open-source software used to store structured data, which can be used as a database, cache, or message broker. It is a very powerful and popular
KEY-VALUE data storage system today. Redis stands out because it supports many basic data structures such as hash, list, set, sorted set, string. All data is recorded and stored in RAM, so data read and write speed will be very fast. For details on installation and configuration steps, please see below.
Note: This Redis Socket feature is only available on DirectAdmin Pro Pack. Regular DirectAdmin licenses will not have this feature.

Step 2: Install the Plugin and Activate Redis
If you are using the free WP-Rocket plugin offered by AZDIGI (or cache plugins that don’t support Object Cache), you can add Redis by installing the Redis Object Cache plugin. AZDIGI recommends that you install the above Plugin to configure the Object Cache instead of configuring it directly into the Plugin (with Object Cache support), this will reduce some errors or warnings related to Memory.
After installation is complete, go to Plugins => click Enable Object Cache to activate.
If the screen shown below, you have successfully activated Redis.
Thus, AZDIGI has shown you how to enable Redis cache on SEO Hosting service and connect to the WordPress website very simply. Configuring the use of Redis cache will help your website increase its load capacity, helping it operate stably and have a faster access speed.
