从上面信息得知：(VI_1): ip address associated with VRID 51 not present in MASTER advert : 10.8.8.100

keepalived

不同的vrrp实例应该具有不同的virtual_router_id值。相同的VRRP实例应该具有相同的值。
virtual_router_id 是区分不同的实例。51被其它的实例占用，取值范围0~255.
您需要在同一群集中的成员上具有相同的值。如果您有另一个群集，其成员应该具有另一个值。Virtual_router_id每个vrrp群集应该是唯一的。

所以只需要将 keepalived.conf配置中的virtual_router_id改成其它值即可。如换成：49.重启即可。

! Configuration File for keepalived

global_defs {
   router_id backup
}

vrrp_script chk_nfs {
    script "/etc/keepalived/nfs-check.sh"
    interval 2
    weight -20
}

vrrp_instance VI_1 {
    state BACKUP
    interface bond0
    virtual_router_id 49
    priority 80
    advert_int 1
    nopreempt  

    authentication {
        auth_type PASS
        auth_pass 1111
    }
    track_script {
         chk_nfs
    }
    virtual_ipaddress {
        10.8.8.100
    }
}
