How to integrate Redis into your website for fast and efficient caching

Procédure

Introduction to Redis and its usefulness in web applications

Redis is an in-memory data structure storage system used as a database, cache, and message broker. For a WordPress site, Redis offers a significant performance improvement by reducing page load times. Acting as an advanced object cache, Redis stores frequently requested data in memory, enabling fast access and reducing the load on the database. This capability is particularly useful for high-traffic WordPress sites, where reducing database queries can greatly improve the user experience and reduce server response times. In addition, Redis supports data structures such as strings, lists, and sets, offering flexibility in data management for WordPress developers.

How do I enable Redis on my LWS shared hosting?

If you have a Linux LWS shared hosting plan (excluding cPanel), you can enable Redis from your LWS client area.

To do this, you simply need to:

11. First, you need to log in to your LWS account and access the shared hosting for which you want to enable Redis.

22. Find the "Optimization and performance" category and click on "Memcached/Redis"

33. In the modal that opens, check the enable button

44. Confirm and wait about 5 minutes for Redis to be properly configured on your service.

An indicator on the home page of your service management interface will show you an approximate countdown of the remaining time before it takes effect.

After the wait, Redis is now operational on your service. We will now see together how to set it up in the case of a site created with WordPress.

How do I use Redis for my WordPress site?

To use Redis on your WordPress site, we recommend using the "Redis Cache" plugin.

To do this, log in to the admin area of your Wordpress site, then simply go to the left-hand menu and click on "Plugins".

Click on the Add button at the top of the page.

Search for the plugin using the search bar by entering "Redis Cache"

Once you find it in the list, click on "Install now" and once that is finished, click on "activate".

It is recommended to add a specific prefix in the wp-config.php file, using the following constant:

define( 'WP_REDIS_PREFIX', 'your_unique_prefix_' );

This helps avoid conflicts between multiple sites using the same Redis server.

Then, in the left-hand menu, click on "Settings" in your WordPress dashboard, then click on "Redis".

If you have enabled Redis on the LWS client panel, you will have an "Enable object cache" button that you must click for Redis to be operational for your WordPress site; there is nothing else you need to do.

If not, this button will not appear, meaning that Redis is not enabled on your service. In that case, I invite you to go back to the previous section to enable it on your LWS Panel.
