Configure Yii component

'redis' => [
        'class' => 'yii\redis\Connection',
        'hostname' => 'localhost',
        'port' => 6379,
        'database' => 0,
],
这样我们的redis就配置完成了，接下来就是验证了
public function actionIndex()
{   
    Yii::$app->redis->set('test','111');  //设置redis缓存
    echo Yii::$app->redis->get('test');   //读取redis缓存
    exit;
    return $this->render('index');
}

The page outputs "111", which means that the redis configuration is successful
