1.) SSH into your account.
2.) Navigate to your craft installation folder.
3.) Run the following command:
composer require --prefer-dist yiisoft/yii2-redis
4.) Once installed, you'll need to edit the config/app.php file to include the following code:
'components' => [
'cache' => [
'class' => yii\redis\Cache::class,
'defaultDuration' => 86400,
'redis' => [
'unixSocket' => '/home/USER/.kxcache/redis.sock',
'database' => 0,
5.) When adding the code, make sure to edit the 'USER' with your cPanel user. Also, make sure to specify a unique database number (0, 1, 2, etc) if you have multiple instances of redis.
