Question

我有一个Python脚本，我想作为守护进程运行。我是通过创建单元文件/etc/systemd/system/service

来做到这一点的

我希望将其作为systemctl start/stop/restart myservice

运行

依赖于此start stop个参数，我正在处理系统信号，例如SIGUP，SIGINT

问题是我可以运行我的脚本，因为Python main.py启动/停止/重启并且我的逻辑有效。

但是在转换成单元文件后，这个python文件被ExecStart调用，我不知道如何在那里传递参数？

Answer 1

不是你实际上正在运行＆＃34; main.py start＆＃34;和＆＃34; main.py停止＆＃34;？在那种情况下，你编写了一个＆＃34;分叉＆＃34;服务。
