    import win32serviceutil
    import win32service
    import win32event
    import time
    class SmallestPythonService(win32serviceutil.ServiceFramework):
        _svc_name_ = "SmallestPythonService"
        _svc_display_name_ = "The smallest possible Python Service"
        def __init__(self, args):
            win32serviceutil.ServiceFramework.__init__(self, args)
            # Create an event which we will use to wait on.
            # The "service stop" request will set this event.
            self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
    
        def SvcStop(self):
            # Before we do anything, tell the SCM we are starting the stop process.
            self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
            # And set my event.
            win32event.SetEvent(self.hWaitStop)
    
        def SvcDoRun(self):
            #你需要运行的代码#
            while True:
                f= open('c:/a.log','a')
                f.write('asdf\n')
                f.close()
                time.sleep(5)
            win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)
    
    if __name__=='__main__':
        win32serviceutil.HandleCommandLine(SmallestPythonService) 


    启动的方法就是直接在cmd下,脚本名.py install ,然后去windows 的服务下就可以看到The smallest possible Python Service 这个服务,你可以启动,停止,还可以设置成开机自动启动。


    有个需要注意的地方:

    该脚本名不能为中文!!否则在启动服务时会出现“ Windows 不能 在本地计算机 启动 The smallest possible Python Service .....“的错误信息
