How do I use two database?

I tried this format but could not:


return [

'components' => [

    'db1' => [

        'class' => 'yii\db\Connection',

        'dsn' => 'mysql:host=localhost;dbname=db1name',

        'username' => 'db1username',

        'password' => 'db1password',

    ],

    'db2' => [

        'class' => 'yii\db\Connection',

        'dsn' => 'mysql:host=localhost;dbname=db2name',

        'username' => 'db2username',

        'password' => 'db2password',

    ],

],

];
