自己搭建好MySQL MMM(Master-Master Replication Manager)高可用架构后看不到vip地址,经过在网上找了大量的文章和自己平时的观察
自己搭建好MySQL MMM(Master-Master Replication Manager)高可用架构后看不到vip地址,经过在网上找了大量的文章和自己平时的观察终于发现找出vip地址的方法了,现在分享给大家。
1.在mmm监控服务器查看各节点的状态
[root@node2 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)
[root@node2 bin]#
2.在db2节点中应该就有192.168.56.100的vip地址
[root@db2 bin]# ip a
1: lo:
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0:
link/ether 08:00:27:e0:ac:97 brd ff:ff:ff:ff:ff:ff
inet 10.0.2.15/24 brd 10.0.2.255 scope global eth0
inet6 fe80::a00:27ff:fee0:ac97/64 scope link
valid_lft forever preferred_lft forever
3: eth1:
link/ether 08:00:27:a1:d1:2d brd ff:ff:ff:ff:ff:ff
inet 192.168.56.105/24 brd 192.168.56.255 scope global eth1
inet 192.168.56.100/32 scope global eth1 --这就是vip写地址
inet6 fe80::a00:27ff:fea1:d12d/64 scope link
valid_lft forever preferred_lft forever
[root@db2 bin]#
3.在node1节点中应该就有192.168.56.200的vip地址
[root@node1 ~]# ip a
1: lo:
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0:
link/ether 08:00:27:8e:fe:c6 brd ff:ff:ff:ff:ff:ff
inet 192.168.56.102/24 brd 192.168.56.255 scope global eth0
inet 192.168.56.200/32 scope global eth0 --这是vip读地址
inet6 fe80::a00:27ff:fe8e:fec6/64 scope link
valid_lft forever preferred_lft forever
3: eth1:
link/ether 08:00:27:65:75:66 brd ff:ff:ff:ff:ff:ff
inet 10.0.3.15/24 brd 10.0.3.255 scope global eth1
inet6 fe80::a00:27ff:fe65:7566/64 scope link
valid_lft forever preferred_lft forever
[root@node1 ~]#
