Using the Cache component

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

return [
    //....
    'components' => [
        // ...
        'cache' => [
            'class' => 'yii\redis\Cache',
        ],
    ]
];

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

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