How to configure Joomla to use Redis

This article describes how to configure Joomla to use Redis.

Redis is an open-source memory object caching system that websites can use to help accelerate page load times. Redis works by caching in RAM frequently accessed data, such as the results of API calls, database calls, and more.

  • Redis is currently enabled on Managed VPS and Managed Dedicated server accounts.
  • If you have an unmanaged VPS or unmanaged Dedicated Server, you have full root access and can install and configure Redis yourself.
  • Redis is not supported on shared hosting accounts at this time.
