keepalived 实战
作者:互联网
两个节点:10.0.2.18 和 10.0.2.19
1、安装:yum install -y keepalived
2、查看配置文件位置:rpm -qc keepalived
3、修改配置文件:
10.0.2.18上的配置文件: global_defs { router_id zcylb } vrrp_instance VI_1 { state MASTER interface enp0s3 unicast_peer { 10.0.2.19 } virtual_router_id 51 priority 100 advert_int 1 authentication { auth_type PASS auth_pass 1111 } virtual_ipaddress { 10.0.2.250 dev enp0s3 } }
其中 10.0.2.250 是我随便设的一个没有被使用的ip,因为我的网卡叫enp0s3,所以配置文件里写的是enp0s3
10.0.2.19上的配置文件: global_defs { router_id zcylb } vrrp_instance VI_1 { state BACKUP interface enp0s3 unicast_peer { 10.0.2.18 } virtual_router_id 51 priority 90 advert_int 1 authentication { auth_type PASS auth_pass 1111 } virtual_ipaddress { 10.0.2.250 dev enp0s3 } }
4、启动keepalived
service keepalived start
5、查看效果
6、停掉master的keepalived
service keepalived stop , 发现虚拟ip漂移了
注:在启停keepalived时,也可以查看日志
tail -f /var/log/messages
