1.兩個節點都啟動

#由於節點1的優先順序高於節點2，所以VIP在節點1上面
[root@lb01 ~]# ip addr | grep 10.0.0.3
    inet 10.0.0.3/32 scope global eth0

[root@lb02 ~]# ip addr | grep 10.0.0.3

2.停止主節點

[root@lb01 ~]# systemctl stop keepalived

#節點2聯絡不上節點1，主動接管VIP
[root@lb02 ~]# ip addr | grep 10.0.0.3
    inet 10.0.0.3/32 scope global eth0

3.重新啟動主節點

[root@lb01 ~]# systemctl start keepalived

#由於節點1的優先順序高於節點2，所以恢復節點1之後，vip又漂回節點1
[root@lb01 
 
~]# ip addr | grep 10.0.0.3
    inet 10.0.0.3/32 scope global eth0

4.配置非搶佔式

1）節點一修改

[root@lb01 ~]# vim /etc/keepalived/keepalived.conf 
... ...
vrrp_instance VI_1 {
    state BACKUP
    nopreempt
    ......
}

[root@lb01 ~]# systemctl restart keepalived

2）節點2修改

[root@lb02 ~]# vim /etc/keepalived/keepalived.conf 
... ...
vrrp_instance VI_1 {
    state BACKUP
    nopreempt
    ......
}

[root@lb02 
 
~]# systemctl restart keepalived

3）配置注意事項

1.兩臺機器節點狀態都要改成 BACKUP
2.兩個節點都要加上 nopreempt
3.優先順序不需要改變

5.訪問頁面測試
