Predis for Redis Cache, Session, and ActiveRecord ¶
Configuring application ¶
To use this extension, you have to configure the yii\redis\predis\PredisConnection class in your application configuration:
Warning: The yii\redis\predis\PredisConnection class supports redis-cluster connection, but does not provide support for the cache, session, ActiveRecord, mutex component interfaces.

'components' => [
'redis' => [
'class' => 'yii\redis\predis\PredisConnection',
'parameters' => [
'tcp://redis-node-1:26379',
'tcp://redis-node-2:26379',
'tcp://redis-node-3:26379',

More detailed information about the configuration and connection parameters can be found in the predis documentation.
This provides the basic access to redis storage via the redis application component:
Yii::$app->redis->set('mykey', 'some value');
echo Yii::$app->redis->get('mykey');
