测试keepalived主备模式

目的：观察VIP在主备服务器上的切换过程

一、安装
yum -y install ipvsadm keepalived

二、服务配置
【keepalived  主】
[root@R201-1 ~]# cat /etc/keepalived/keepalived.conf 
! Configuration File for keepalived

global_defs {
   router_id R201-1
}

vrrp_instance VIP_Mysql {
    state MASTER
    interface em1
    virtual_router_id 150
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        10.0.201.100
    }
}
[root@R201-1 ~]# service keepalived start

【keepalived  备】
[root@201-2 ~]# cat /etc/keepalived/keepalived.conf 
! Configuration File for keepalived

global_defs {
   router_id R201-2
}

vrrp_instance VIP_Mysql {
    state BACKUP
    interface em1
    virtual_router_id 150
    priority 50
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        10.0.201.100
    }
}
[root@R201-2 ~]# service keepalived start
