Answer 1

服务单元文件应该设置一个RestartSec，大多数开发人员都忘记了这一点。

Restart=on-failure
RestartSec=3

Answer 2

您应该可以找到application.service

locate application.service

并检查ExecStart启动的文件是否存在。

也许您已经升级了系统，而配置文件是旧文件，您需要提交。

Gentoo做到了。

Answer 3

不需要使用定位实用程序来查找application.service。

执行：

systemctl status application.service

显示状态+静态路径

可以分享application.service的内容吗？你能使用ExecStart=中的命令运行应用程序吗？

足够的特权也可能是一个问题。检查单元文件的[Service]部分中的指令User=和Group=。
