Redis	2

Configure the Redis driver

To enable the replication, simply change the replication.driver name in the websockets.php file to redis:

'replication' => [

    'driver' => 'redis',

    ...

],

You can set the connection name to the Redis database under redis:

'replication' => [

    ...

    'redis' => [

        'connection' => 'default',

    ],

],

The connections can be found in your config/database.php file, under the redis key. It defaults to connection default.
