  Preface       I've installed MasterHA yesterday,Now let's test the master-slave switch and failover feature.   Framework  
Hostname IP Port Identity OS Version MySQL Version
zlm2 192.168.1.101 3306 master CentOS 7.0 5.7.21
zlm3 192.168.1.102 3306 slave/mha-manager CentOS 7.0 5.7.21
null 192.168.1.200 null vip null null
Procedure   Test 1：Manual master switchover   Check state of MHA-manager on zlm3.
