scrapy-cluster：socket.error：[Errno 98]地址已被使用

Posted 2021-04-06

我试图在this quick-start.之后运行scrapy-cluster我遇到了以下错误。

# python rest_service.py

    return getattr(self._sock,name)(*args)
socket.error: [Errno 98] Address already in use

我该如何使用另一个端口。

答案

您可以使用sudo netstat -nlp | grep :5343检查哪个进程正在使用该端口

然后使用其PID kill -9 <pid>终止该进程

另一答案

转到rest cluster中的localsettings.py并更改FLASK端口

不确定为什么群集开始时端口5343已经被python使用并且无法杀死
