How do I use Redis on my site?

Redis is an in-memory cache. Instead of rebuilding every page by querying the database, your site stores the results in RAM and then reads them back in a fraction
of a millisecond. On a reasonably busy WordPress, Laravel, Magento or PrestaShop site, this is often the most visible performance gain for the least effort.

Your Redis instance is private: it is reserved for you, it runs under your own user account, and no other customer on the server can access it.

How do I enable Redis?

In cPanel, under Databases, open Redis, choose the profile closest to your site (WordPress, Laravel / Symfony, Magento / PrestaShop, or PHP sessions)
then click Enable Redis. The instance starts immediately and the page displays your connection details.

All the settings remain editable afterwards: the profile only pre-fills the memory limit, the eviction policy and the number of databases.

Which connection details should I use?

The cPanel Redis page displays everything your application needs:

• the socket file, in the form /home/youraccount/.redis/redis.sock;
• the password (Show button to read it, Copy to grab it);
• the database number to use;
• depending on your plan, a host and port (see below).

Socket or port: what's the difference?

The socket is a local communication file. This is the recommended method: it is faster than the network, and the data never leaves the server. All the common clients support it, in particular the PHP phpredis extension, LiteSpeed Cache and Laravel.

The port (on 127.0.0.1) exists for the rare applications that cannot use a socket. It is included from the SITE PRO plan upwards. On the other plans, use the socket: you lose nothing in functionality, quite the contrary.

How do I configure WordPress?

The simplest option is the LiteSpeed Cache plugin, under Cache > Object:

• method: Redis;
• host: paste the path to the socket file;
• port: 0;
• password: the one shown in cPanel;
• database: your database number.

With the Redis Object Cache plugin, add these lines to wp-config.php instead, before the /* That's all, stop editing! */ line:

define( 'WP_REDIS_SCHEME', 'unix' );
define( 'WP_REDIS_PATH', '/home/youraccount/.redis/redis.sock' );
define( 'WP_REDIS_PASSWORD', 'your_password' );
define( 'WP_REDIS_DATABASE', 0 );

Then enable the object cache from the plugin. The cPanel Redis page displays this block pre-filled with your values: you can copy it directly.

How do I configure Laravel or Symfony?

In your application's .env file:

REDIS_CLIENT=phpredis
REDIS_HOST=/home/youraccount/.redis/redis.sock
REDIS_PORT=0
REDIS_PASSWORD=your_password
REDIS_DB=0
CACHE_DRIVER=redis
SESSION_DRIVER=redis

Remember to clear your application's configuration cache afterwards
(php artisan config:clear).

Can I access it from the command line?

Yes, from an SSH connection or the cPanel Terminal. The page displays the exact command, password included:

redis-cli -s /home/youraccount/.redis/redis.sock -a 'your_password'

Can I connect to it from outside the server?

No, and that is deliberate. Your instance only listens on the server itself. A cache reachable from the Internet is a risky way in.
