Redis is a powerful open-source in-memory database that is excellent for applications such as caching, session management and speeding up data processing. Our servers make full use of Redis software to improve performance, and this technology can also be easily integrated with your WordPress website. Activating Redis requires only a few simple steps and can be completed within minutes.
Make sure Redis is enabled in the cloud panel. Go to Advanced → Developer Tools and activate (toggle) the last option, Redis.
Log in to WordPress and go to Plugins. In the library, search for Redis and install it.
In WordPress, go to Settings → Redis
Click on Enable Object Cache.
You may get a 502: Bad Gateway error after activating Redis. This is usually caused because the Redis configuration is not yet correctly connected to the application server. This is easily solved by restarting your PHP container. At Advanced → Developer Tools, select the first Restart button under .PHP
If all the previous steps have been performed correctly, you can check that the client has successfully connected to the server. Redis is now active.
