Using the Session component ¶

To use the Session component, in addition to configuring the connection as described in the Installation section, you also have to configure the session component to be yii\redis\Session:

return [
    //....
    'components' => [
        // ...
        'session' => [
            'class' => 'yii\redis\Session',
        ],
    ]
];

If you only use redis session (i.e., not using its ActiveRecord or Cache), you can also configure the parameters of the connection within the session component (no connection application component needs to be configured in this case):

return [
    //....
    'components' => [
        // ...
        'session' => [
            'class' => 'yii\redis\Session',
            'redis' => [
                'hostname' => 'localhost',
                'port' => 6379,
                'database' => 0,
            ],
        ],
    ]
];
