Two frontend and one backend in one app Yii Framework 2

I'm working with Yii Framework 2 and I try to figure out how to create app with one backend and two front end for example: - Backend for Admins and Moderators (url: admin.example.com), - Frontend app for Publishers (url: publisher.example.com), - Frontend app for Advertisers (url: advertiser.example.com)

All apps should have common db, models and 3 different layouts. I found yii2 advenced template where are only two: frontend and backend.
