Detailed explanation of examples of creating Windows system services in Python

This article mainly introduces the relevant information of Python to create Windows system services. It has certain reference value. Interested friends can refer to

Recently A Python program needs to be installed and run as a Windows system service. I encountered some pitfalls in the process and sorted them out.

Python service class

First of all, the Python program needs to call some Windows system API to serve as a system service. The specific content is as follows:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
import time
import win32api
import win32event
import win32service
import win32serviceutil
import servicemanager
class 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

# 安装服务
dist\MyService.exe install
# 启动服务
sc start MyService
# 停止服务
sc stop MyService
# 删除服务
sc delete MyService
