Specify the master node meaning in where? The relationship between the master-slave node may be turning from time to time,

CodePudding user response:

Don't know the master node may be two main nodes are on the same host, if there are only 3 main from 3, in the two main nodes are on the same host, not a cluster or hang up, if every one are a primary node, is not,
