如何在HAProxy上使keepalived在故障转移时响应？

Question

我使用HAProxy作为我的应用程序的负载均衡器，并且为了使其高度可用，我使用了keepalive服务和浮动ip地址的概念。但是，每当我的主负载均衡器服务器宕机时，通过将其从网络中移除或将其关闭，我的所有服务都会宕机，而不是使辅助负载均衡器服务器可用。我的主服务器的keepalived.conf是，

global_defs
{
        # Keepalived process identifier
        lvs_id haproxy_DH
}
# Script used to check if HAProxy is running
vrrp_script check_haproxy
{
        script "pidof haproxy"
        interval 2
        weight 2
}
# Virtual interface
vrrp_instance VI_01
{
        state MASTER
        interface eno16777984           #here eth0 is the name of network interface
        virtual_router_id 51
        priority 101
        # The virtual ip address shared between the two loadbalancers
        virtual_ipaddress {
                172.16.231.162
        }
        track_script {
                check_haproxy
        }
}

对于备份服务器，它就像，

global_defs
{
        # Keepalived process identifier
        lvs_id haproxy_DH_passive
}
# Script used to check if HAProxy is running
vrrp_script check_haproxy
{
        script "pidof haproxy"
        interval 2
        weight 2
}
# Virtual interface
vrrp_instance VI_01
{
        state BACKUP
        interface eno16777984           #here eth0 is the name of network interface
        virtual_router_id 51
        priority 100
        # The virtual ip address shared between the two loadbalancers
        virtual_ipaddress {
                172.16.231.162
        }
        track_script {
                check_haproxy
        }
}

当两个负载均衡器都启动时，将分配虚拟IP地址并使其工作。但每当机器停机时，我的服务也会停机。我正在使用CentOS7，请帮助我。

使用这个，

global_defs {

router_id ovp_vrrp

} vrrp_script haproxy_check {脚本"killall 0 haproxy"间隔2权重2}

接口OCP_EXT { vrrp_instance ens192

virtual_router_id 51

优先级100状态主virtual_ipaddress { 10.19.114.231 开发ens192

} track_script { haproxy_check }鉴权{ auth_type通过auth_pass 1cee4b6e-2cdc-48bf-83b2-01a96d1593e4 }}
