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.
The tutorial says to run this client:
#!/usr/bin/env python
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()
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
As you can see rabbitmq-server seems to be running fine in a different window:

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

Make sure the node is running using rabbitmq-diagnostics status. Verify config file is correctly placed and has correct syntax/structure. Inspect listeners using rabbitmq-diagnostics listeners or the listeners section in rabbitmq-diagnostics status. Inspect effective configuration using rabbitmq-diagnostics environment.
A common cause for connections being abruptly closed as soon as they're started is a TCP load balancer's heartbeat. If this is the case you should see these messages at very regular intervals, and the generally accepted practice seems to be to ignore them.
By default, RabbitMQ will listen on port 5672 on all available interfaces. It is possible to limit client connections to a subset of the interfaces or even just one, for example, IPv6-only interfaces.
The client is trying to connect using IPv6 localhost (::1:5672), while the server is listening to IPv4 localhost ({"127.0.0.1",5672}).
Try changing the client to connect to the IPv4 localhost instead;
connection = pika.BlockingConnection(pika.ConnectionParameters('127.0.0.1'))
