Make several front-end applications on one installation of the framework (multi frontend, multi frontend)?

Question

Yii

I want to make more than one front-end application in Advanced Template.
1) I duplicate the frontend folder in frontend2,
2) I change all occurrences of "frontend" to "frontend2" in it,
3) I add an alias to frontend2\config\bootstrap.php file Yii::setAlias('frontend', dirname(dirname(__DIR__ )) .'/frontend2');
4) I hang the domain on the frontend2\web home directory.
The engine does not see the SiteController controller.
If I forcibly include a file with a controller in bootstrap.php, then in the future the layout file does not see the AppAsset class, etc. Moreover, the classes from the standard frontend are visible.
How can I properly set up work with additional frontends?

Answer 1

namespace look carefully, which is specified in the config and yours for the controller.
