为什么我不能使用python建立与rabbitMQ的连接? [英] Why can't I establish connection to rabbitMQ using python?

问题描述

我正在学习如何使用 rabbitMQ.我在 MacBook 上运行 rabbit-MQ 服务器并尝试连接 python 客户端.我按照此处的安装说明进行操作.现在我正在执行此处.

I'm learning how to use rabbitMQ. I'm running the rabbit-MQ server on my MacBook and trying to connect with a python client. I followed the installation instructions here. And now I'm performing the tutorial shown here.

教程说要运行这个客户端:

The tutorial says to run this client:

#!/usr/bin/env python
import pika

connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()

但是，当我这样做时，在尝试建立连接时出现以下错误:

However, when I do, I get the following error while trying to establish the connection:

WARNING:pika.adapters.base_connection:Connection to ::1:5672 failed: [Errno 61] Connection refused

如您所见，rabbitmq-server 似乎在不同的窗口中运行良好:

As you can see rabbitmq-server seems to be running fine in a different window:

  % rabbitmq-server

我怎样才能建立这个连接?有什么问题?

How can I establish this connection? What is the problem?

推荐答案

客户端正在尝试使用 IPv6 localhost (::1:5672) 进行连接，而服务器正在侦听 IPv4 localhost ({"127.0.0.1",5672}).

The client is trying to connect using IPv6 localhost (::1:5672), while the server is listening to IPv4 localhost ({"127.0.0.1",5672}).

尝试更改客户端以连接到 IPv4 本地主机；

Try changing the client to connect to the IPv4 localhost instead;

connection = pika.BlockingConnection(pika.ConnectionParameters('127.0.0.1'))
