如何通过Python启动win32服务

Question

我必须将我的python脚本作为win32服务运行，如下所示：

aservice.py

import win32service
import win32serviceutil
import win32api
import win32con
import win32event
import win32evtlogutil
import os

class aservice(win32serviceutil.ServiceFramework):

   _svc_name_ = "aservice"
   _svc_display_name_ = "a service - it does nothing"
   _svc_description_ = "Tests Python service framework by receiving and echoing messages over a named pipe"

   def __init__(self, args):
           win32serviceutil.ServiceFramework.__init__(self, args)
           self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)           

   def SvcStop(self):
           self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
           win32event.SetEvent(self.hWaitStop)                    

   def SvcDoRun(self):
      import servicemanager      
      servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,servicemanager.PYS_SERVICE_STARTED,(self._svc_name_, '')) 

      self.timeout = 3000
      from cron.realtimemonitorschedule import startMonitor
      startMonitor()
      while 1:
         # Wait for service stop signal, if I timeout, loop again
         rc = win32event.WaitForSingleObject(self.hWaitStop, self.timeout)
         # Check to see if self.hWaitStop happened
         if rc == win32event.WAIT_OBJECT_0:
            # Stop signal encountered
            servicemanager.LogInfoMsg("aservice - STOPPED")
            break
         else:
            servicemanager.LogInfoMsg("aservice - is alive and well")   


def ctrlHandler(ctrlType):
   return True

if __name__ == '__main__':   
   win32api.SetConsoleCtrlHandler(ctrlHandler, True)   
   win32serviceutil.HandleCommandLine(aservice)

我可以成功安装该服务，但是当我启动该服务时，它会提示如下错误：

from cron.realtimemonitorschedule import startMonitor
ImportError: No module named cron.realtimemonitorschedule 

请注意，cron.realtimemonitorschedule是在realtimemonitorschedule.py中定义的，我的问题是如何从win32服务调用我的脚本？我无法在上面的aservice.py

中嵌入我的脚本

我试图搞清楚，我需要让Python找到我的模块。通过设置路径到PYTHONPATH或者只是将整个模块复制到PYTHON_HOME文件夹，后者仅用于测试。
