Why can't I connect to rabbitMQ using python?

Question

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

The manual says that to run this client:

#!/usr/bin/env python import pika connection = pika.BlockingConnection(pika.ConnectionParameters('localhost')) channel = connection.channel() 

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

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

As you can see, the rabbitmq server is working fine in another window:

How to establish this connection? What is the problem?

Answer 1

The client tries to connect using IPv6 localhost ( ::1:5672 ), and the server listens to IPv4 localhost ( {"127.0.0.1",5672} ).

Try changing the client instead to connect to the local IPv4 host;

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