Use Python to create Windows and python Services

Use Python to create Windows and python Services

Recently, a Python program needs to be installed and run as a Windows system service. Some pitfalls have been encountered during the process.

Python service class

First, the Python program must call some Windows system APIs to serve as a system service. The specific content is as follows:

#!/usr/bin/env python# -*- coding: utf-8 -*-import sysimport timeimport win32apiimport win32eventimport win32serviceimport win32serviceutilimport servicemanagerclass MyService(win32serviceutil.ServiceFramework):  _svc_name_ = "MyService"  _svc_display_name_ = "My Service"  _svc_description_ = "My Service"  def __init__(self, args):    self.log('init')    win32serviceutil.ServiceFramework.__init__(self, args)    self.stop_event = win32event.CreateEvent(None, 0, 0, None)  def SvcDoRun(self):    self.ReportServiceStatus(win32service.SERVICE_START_PENDING)    try:      self.ReportServiceStatus(win32service.SERVICE_RUNNING)      self.log('start')      self.start()      self.log('wait')      win32event.WaitForSingleObject(self.stop_event, win32event.INFINITE)      self.log('done')    except BaseException as e:      self.log('Exception : %s' % e)      self.SvcStop()  def SvcStop(self):    self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)    self.log('stopping')    self.stop()    self.log('stopped')    win32event.SetEvent(self.stop_event)    self.ReportServiceStatus(win32service.SERVICE_STOPPED)  def start(self):    time.sleep(10000)  def stop(self):    pass  def log(self, msg):    servicemanager.LogInfoMsg(str(msg))  def sleep(self, minute):    win32api.Sleep((minute*1000), True)if __name__ == "__main__":  if len(sys.argv) == 1:    servicemanager.Initialize()    servicemanager.PrepareToHostSingle(MyService)    servicemanager.StartServiceCtrlDispatcher()  else:    win32serviceutil.HandleCommandLine(MyService)

Pyinstaller Packaging

pyinstaller -F MyService.py

Test

# Install the service dist \ MyService.exe install # start the service SC start MyService # stop the service SC stop MyService # delete the service SC delete MyService
