问题
I am having trouble in my database design. I would like to accomplish all the instances below:
1.) Multi-Master and Single Slave.
2.) Rename database in slave.(Server1 and Server has diff datasets)
]1
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?

This only allows you to set one Master as a source to read
here is the full explation of why its not succesfull.
