How to Enable Redis or Memcache on CPanel Shared Hosting

What is Redis and What is Memcache?

Before we dive into the tutorial, let’s quickly understand what Redis and Memcache are.

Redis (Remote Dictionary Server) is an in-memory data store that can be used as a database, message broker, and more. It’s known for its high performance, low latency, and ability to handle large amounts of data.

Memcache, on the other hand, is a high-performance caching system that stores frequently accessed data in RAM (Random Access Memory). This allows your website to quickly retrieve data without having to query the database, resulting in faster page loads.

How Can Redis and Memcache Boost Website Performance?

Both Redis and Memcache can significantly improve your website’s performance by:

• Reducing database queries: By storing frequently accessed data in RAM, Redis and Memcache reduce the number of database queries, resulting in faster page loads.
• Improving response times: By storing data in RAM, Redis and Memcache can retrieve data much faster than traditional disk-based storage.
• Increasing scalability: By offloading database queries, Redis and Memcache enable your website to handle more traffic and users.

Note: Can I Use Redis or Memcache on any CPanel Hosting?

The simple answer is NO. Very rare to find a cpanel shared hosting provider that having Redis & Memcached built into their packages. In order to support both caching mechanisms, it will require high amount of server resources and extra configurations on the server side. In short, in order to make the Redis/Memcached works for your website, there’re 2 Important items that must be supported by the hosting, typically, the cache module and the php extension:

1. The cPanel MUST have Redis/Memcached module installed.
2. The cPanel MUST have redis/memcache/memcached php extension installed.

Most cpanel hosting providers have the redis/memcache php extension installed, BUT they don’t have the Redis/Memcached module installed & configured, thus redis/memcache caching will not work.
