然后通过命令查看虚拟IP状态：
# ip ad li
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:5c:e0:13 brd ff:ff:ff:ff:ff:ff
inet 10.0.0.7/24 brd 10.0.0.255 scope global eth0
inet 10.0.0.11/32 scope global eth0 ===============>此处为虚拟IP
inet6 fe80::20c:29ff:fe5c:e013/64 scope link
valid_lft forever preferred_lft forever
# ip ad li
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:38:4b:e3 brd ff:ff:ff:ff:ff:ff
inet 10.0.0.8/24 brd 10.0.0.255 scope global eth0
inet6 fe80::20c:29ff:fe38:4be3/64 scope link
valid_lft forever preferred_lft forever
停掉linux-node1上面的keepalived服务然后再查看状态：
# /etc/init.d/keepalived stop
停止 keepalived： [确定]
然后再次通过命令查看虚拟IP状态：
# ip ad li
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:5c:e0:13 brd ff:ff:ff:ff:ff:ff
inet 10.0.0.7/24 brd 10.0.0.255 scope global eth0
inet6 fe80::20c:29ff:fe5c:e013/64 scope link
valid_lft forever preferred_lft forever
# ip ad li
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:38:4b:e3 brd ff:ff:ff:ff:ff:ff
inet 10.0.0.8/24 brd 10.0.0.255 scope global eth0
inet 10.0.0.11/32 scope global eth0 ==================>虚拟IP已漂移到linux-node2上面
inet6 fe80::20c:29ff:fe38:4be3/64 scope link
valid_lft forever preferred_lft forever
