centos - keepalived vrrp_script 不进行故障转移

Question

我有 2 个带有 keepalived 和 haproxy 服务的节点(CentOS7)。
如果我关闭一个节点一切正常。但是如果 haproxy 出现故障，我想对 VIPS 进行故障转移。

这是第一个节点配置:

  vrrp_script ha_check {
script "/etc/keepalived/haproxy_check"
interval 2
weight 21
}

vrrp_instance VI_1 {
    state MASTER
        interface eno16777984
        virtual_router_id 151
        priority 101
        advert_int 1
        authentication {
        auth_type PASS
        auth_pass 11111
                        }
        virtual_ipaddress {
                10.0.100.233
                            }
        smtp_alert
track_script {
ha_check
}
}

第二个节点:

vrrp_script ha_check {
script "/etc/keepalived/haproxy_check"
interval 2
fall 2
rise 2
timeout 1
weight 2
}

vrrp_instance VI_1 {
    state BACKUP
        interface eno16777984
        virtual_router_id 151
        priority 100
        advert_int 1
        authentication {
        auth_type PASS
        auth_pass 11111
                        }
        virtual_ipaddress {
                10.0.100.233
                            }
        smtp_alert
track_script {
ha_check
}
}

猫/etc/keepalived/haproxy_check

systemctl status haproxy | grep "inactive"

当我停止 haproxy 时，它仍然不会将 VIP 故障转移到下一个
主持人。

[root@cks-hatest1 keepalived]# tail /var/log/messages

我做错了什么？先感谢您!

在您的脚本中，您正在检查是否

systemctl status haproxy

包含关键字“inactive”。这是您手动停止 haproxy 服务时获得的值(value)吗？

一旦 haproxy 服务停止，您的日志包含它就会再次启动。你能证实吗？

另外，尝试将脚本替换为

script "killall -0 haproxy"
