Shell 错误保留-故障状态

我正在尝试使用KeepAlive监视某些服务。 请参阅我的配置文件“keepalived.conf”：

在我的脚本中，我将比较pid文件的编号和服务进程：

#!/bin/bash
# check if haproxy is running, return 1 if not.
# Used by keepalived to initiate a failover in case haproxy is down

process=""
HAPROXY_STATUS=""

if [ -f "/var/run/haproxy.pid" ]
then
        process=$(cat /var/run/haproxy.pid)
        HAPROXY_STATUS=$(ps -aux | grep -w "$process.*[h]aproxy")
fi

if [ "$HAPROXY_STATUS" ]
then
        exit 0
else
        exit 1
fi

我的问题是，当我开始保存命令时：

keepalived -f /etc/keepalived/keepalived.conf --dont-fork --log-console --log-detail    

万事如意，万事如意。但当我使用systemd启动服务时：

systemctl start keepalived

我的“/var/log/messages”文件中有以下几行：

---

有人有什么想法吗？

我正在使用非常简单的配置来实现同样的目的。默认情况下，大多数OSs Linux上都必须有实用程序pidof。请尝试以下示例：

vrrp_script check_haproxy
{
    script "pidof haproxy"
    interval 2
    weight 2
}

这是一个有效的解决方案，伙计。

在启动KeepAlive作为systemctl服务时，我的

track\u脚本

也遇到了类似的问题

我发现将我的

跟踪脚本

放入

/usr/libexec/keepalived

解决了这个问题。这可能是因为

在脚本部分使用脚本的地址时，我也有同样的问题，但使用命令是可以的，您找到解决方案了吗？有没有办法在脚本部分使用某个脚本的地址而不是命令？嗨！你能分享一下你在健康检查脚本中使用了什么吗？
