Python制作Windows系统服务

最近有个Python程序需要安装并作为Windows系统服务来运行，过程中碰到一些坑，整理了一下。

Python服务类

首先Python程序需要调用一些Windows系统API才能作为系统服务，具体内容如下：

    #!/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打包

    pyinstaller -F MyService.py

测试

    # 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
