主主上keepalived的配置

主主上keepalived的配置如下：

主节点配置文件：

global_defs {
    router_id lb01
}

vrrp_instance VI_1 {
    state MASTER
    interface enp0s3
    virtual_router_id 50
    priority 150
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        10.0.2.3
    }
}

备用节点配置文件：

global_defs {
    router_id lb02
}

vrrp_instance VI_1 {
    state BACKUP
    interface enp0s3
    virtual_router_id 50
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        10.0.2.3
    }
}

这里的配置文件中，主节点的router_id设置为lb01，备用节点的router_id设置为lb02。vrrp_instance中的state分别设置为MASTER和BACKUP，priority分别设置为150和100。virtual_ipaddress是虚拟IP地址，主备节点都需要配置相同的虚拟IP地址。authentication部分是认证配置，auth_type设置为PASS，auth_pass设置为1111。这样配置后，当主节点故障时，备用节点会接管虚拟IP地址和服务。\[1\] \[3\]
