python 做成windows service 不完全版

前面有提到过python 在ubuntu  配置为启动服务,只需要在rc.local 中配置就好。在WINDOWS中呢,需要借助于PYWIN32扩展模块,py2exe,来完成。
1.先写服务类 iNetServerService.py
程序代码 程序代码

        server_path = os.path.join(server_dir, 'inetgarment', 'start.bat')

    def StartControl(self,ws):

        win32event.WaitForSingleObject(ws, win32event.INFINITE)
        self.stopping = True

    def SvcDoRun(self):
        # Start OpenERP Server itself
        self.StartiNet()
        # start the loop waiting for the Service Manager's stop signal
        thread.start_new_thread(self.StartControl, (self.hWaitStop,))
        # Log a info message that the server is running
        servicemanager.LogInfoMsg("iNet Server up and running")
        # verification if the server is really running, else quit with an error
        self.terpprocess.wait()
        if not self.stopping:
            sys.exit("iNet Server check: server not running, check the logfile for more info")



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


准备一个 start.bat文件:
程序代码 程序代码

cd \
cd C:\iNet\inetgarment
python C:\iNet\inetgarment\serversocket.py


然后执行 python iNetServerService.py install

就可以了。

问题:可以在windows服务里配置程自动启动,但停止服务,并没有停止,原因在于调用的BAT文件,停止服务只会停止cmd,不会停止python. 所以更好的办法不是调用BAT文件,而是启动EXE文件。以后有时间再测试。
