最近做了公司签到的小工具，有同事要求做成Windows服务，开机自启。先说下怎么用Python写Windows服务程序。

推荐大家对比网上其他的人的代码对照看下。SvcDoRun这个函数里面放的就是你实际想做的事情。

安装服务

python PythonService.py install

让服务自动启动

python PythonService.py --startup auto install 

启动服务

python PythonService.py start

重启服务

python PythonService.py restart

停止服务

python PythonService.py stop

删除/卸载服务

python PythonService.py remove

我自己是用pyinstaller打包成exe给别人用的。

PS：脚本编好之后，调试了很久。刚开始会报服务无法启动的问题。具体的排查方式可以看Windows事件查看。
