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

        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：

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。
