带有两个进程的win32serviceutil.ServiceFramework

Question

我试图将两个进程加载到win32serviceutil.ServiceFramework中，但是什么也没有发生。 如果添加run（）语句，则只有第一个过程有效。

当两个进程直接加载到 main 中时，它们同时工作。

import win32serviceutil, win32service, win32event, servicemanager
import traceback, sys, os, time

from multiprocessing import Process

class Service(win32serviceutil.ServiceFramework):
    _svc_name_ = 'serviceteste'
    _svc_display_name_ = 'Service Teste'
    _svc_description_ = 'Service Teste'

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

    def SvcStop(self):
        self.isAlive = False                            
        self.ReportServiceStatus(win32service.SERVICE_CONTROL_STOP)        

        self.pr_srv_1.terminate()
        self.pr_srv_2.terminate()        

        win32event.SetEvent(self.hWaitStop)

    def SvcDoRun(self):

        servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE, 
                    servicemanager.PYS_SERVICE_STARTED,(self._svc_name_, ''))   
        self.timeout = 10000                                                            
        while self.isAlive:
            rc = win32event.WaitForSingleObject(self.hWaitStop, self.timeout)

            if rc == win32event.WAIT_OBJECT_0:
                servicemanager.LogInfoMsg(self._svc_name_ + " - STOPPED!")                                                               
                break
            else:

                try:

                    self.pr_srv_1 = Process(target=proces_1).start()                                        
                    self.pr_srv_2 = Process(target=proces_2).start()

                except Exception as e:  
                    print traceback.format_exc()

def proces_1():
    while True:
        print('Process 1...')
        time.sleep(3)

def proces_2():    
    while True:
        print('Process 2...')
        time.sleep(3)        


if __name__ == '__main__': 
    win32serviceutil.HandleCommandLine(Service)

使用win32serviceutil.ServiceFramework仅允许一个进程吗？
