Question

从源代码构建时，我在使用systemd进行keepalive工作时遇到了一些麻烦。我将单元文件从包安装的keepalived复制到centos 7，它主要用于启动和停止keepalived进程，但当keepalived进入FAULT状态时，systemd显示它不断退出代码256 。从包装中安装时，它会正确显示FAULT状态。我不确定有关systemd的两个安装之间有什么区别。

[Unit]
Description=LVS and VRRP High Availability Monitor
After=syslog.target network.target

[Service]
Type=forking
KillMode=process
EnvironmentFile=-/etc/sysconfig/keepalived
ExecStart=/usr/local/sbin/keepalived $KEEPALIVED_OPTIONS
ExecReload=/bin/kill -HUP $MAINPID
PIDFile=/var/run/keepalived.pid

[Install]
WantedBy=multi-user.target

该过程开始并停止正常，但遇到FAULT状态时，我得到了这个：

Answer 1

在keepalived project的维护者的大力帮助下，确定keepalived实际上正在进入FAULT状态，但是然后详细记录了vrrp_script失败，这是在版本之后添加的内容可用于centos yum repo。

当从源构建时，keepalived在systemd中的FAULT状态下以代码256退出
