MySQL MMM architecture does not see the VIP address

Self-built MySQL mmm (master-master Replication Manager) high-availability architecture can not see the VIP address, after looking for a large number of articles on the Internet and their usual observation finally found a way to find the VIP address, Now share to everyone.

1. View the status of each node in the MMM monitoring server

[Email protected] bin]# Mmm_control Show
DB2 (192.168.56.105) master/online. Roles:writer (192.168.56.100)
Node1 (192.168.56.102) master/online. Roles:reader (192.168.56.200)

[Email protected] bin]#

2. There should be a 192.168.56.100 VIP address in the DB2 node

[[Email protected] bin]# IP A

3. There should be a 192.168.56.200 VIP address in the Node1 node
