Currently i can replicate database by 1 master per slave. But i can't do it the way i want it (Just like the above picture). I read about Multi-source replication in mysql 5.7 but it says that it is not advisable for production. And i don't think that was i'm looking for.

I am using ubuntu, nginx and mysql. How can i accomplish this design?
