(as mentioned by xiangdong...@gmail.com) Write your own daemon or script to poll each master, in turn, by adjusting the slave's replication configuration in some kind of round-robin technique (several of these scripts are on the web). Using the native replication process, no MySQL versions (5.7 or earlier) support one slave replicating data from multiple masters. It is possible to have multiple slaves replicating from a single master but you cannot have one slave repicating from multiple masters. Why are you not reading the responses you are getting?
