How to install Redis on WordPress and why it is better than other options

Redis: A Powerful Tool for WordPress

Redis is an open-source, in-memory data structure store that can be used as a database, cache, and message broker. It is highly versatile and offers numerous benefits for WordPress users. In this article, we will guide you through the process of installing Redis on WordPress and explain why it is a superior choice compared to other caching solutions.

Why Choose Redis?

Redis provides several advantages that make it an excellent option for WordPress users:

  • Lightning-fast Performance: Redis stores data in memory, allowing for incredibly fast read and write operations. This results in significantly reduced page load times and improved overall performance for your WordPress site.
  • Efficient Caching: Redis offers advanced caching capabilities, allowing you to store frequently accessed data in memory. This reduces the need for repeated database queries, resulting in faster response times and improved scalability.
  • Highly Scalable: Redis is designed to handle large amounts of data and high traffic loads. It can easily scale horizontally by adding more servers, ensuring your WordPress site remains responsive even during peak usage periods.
  • Flexible Data Structures: Redis supports a wide range of data structures, including strings, hashes, lists, sets, and more. This flexibility allows you to store and manipulate data in a way that best suits your specific needs.
  • Persistent Storage: Redis can be configured to periodically save data to disk, ensuring data durability and allowing for quick recovery in case of server failures.

Installing Redis on WordPress

Now that you understand the benefits of Redis, let’s walk through the process of installing it on your WordPress site:

  1. Check Server Compatibility: Before proceeding, ensure that your server meets the requirements for running Redis. You will need a server running Linux, macOS, or Windows with a compatible version of PHP.
  2. Install Redis Server: Begin by installing the Redis server on your server. The installation process may vary depending on your operating system. For Linux users, you can typically install Redis using the package manager. For macOS and Windows users, you can download and install Redis from the official website.
  3. Install Redis Object Cache Plugin: Once the Redis server is installed, you need to integrate it with WordPress using a plugin. The Redis Object Cache plugin is a popular choice for this purpose. Install and activate the plugin from the WordPress plugin repository.
  4. Configure Redis Object Cache: After activating the plugin, navigate to the plugin settings page in your WordPress dashboard. Enter the necessary details, such as the Redis server host and port, and save the settings.
  5. Verify Redis Integration: To ensure that Redis is properly integrated with your WordPress site, you can use the Redis Object Cache Test plugin. Install and activate the plugin, then run the test to confirm that Redis is functioning correctly.

Redis vs. Other Caching Solutions

While there are several caching solutions available for WordPress, Redis stands out for its exceptional performance and versatility. Let’s compare Redis with other popular caching options:

  • Redis vs. Memcached: Both Redis and Memcached are in-memory caching systems, but Redis offers more advanced features and data structures. Redis also has better persistence options, making it a more reliable choice for caching.
  • Redis vs. W3 Total Cache: W3 Total Cache is a popular caching plugin for WordPress, but it lacks the advanced features and scalability of Redis. Redis provides better performance and can handle larger traffic loads, making it a superior choice for high-traffic websites.
  • Redis vs. WP Super Cache: WP Super Cache is another widely used caching plugin, but it primarily focuses on static page caching. Redis, on the other hand, offers more comprehensive caching capabilities and can cache dynamic content as well.

Overall, Redis offers unmatched performance, scalability, and flexibility, making it the ideal caching solution for WordPress users.


Redis is a powerful tool that can greatly enhance the performance and scalability of your WordPress site. By installing Redis and leveraging its advanced caching capabilities, you can significantly reduce page load times, improve overall site performance, and handle high traffic loads with ease. Redis outshines other caching solutions with its lightning-fast performance, efficient caching mechanisms, and flexible data structures. Install Redis on your WordPress site today and experience the difference it can make!
