如何连接到 vagrant 主机上的兔子？

Question

I set up a server using vagrant on a virtual machine. After installing rabbitmq, I tried to connect to it using script outside VM. There's already Django and RabbitMQ running on VM. After running a script I have an exception:

pika.exceptions.IncompatibleProtocolError: StreamLostError: ('Transport indicated EOF',)

How to solve my problem?

My friend already used the code provided below on raspberryPi which actually managed to execute it. The only thing I changed on my PC was the hostname changed from the specified IP to my '127.0.0.1'and I added the port number.

import pika
import sys
import random
import time


credentials = pika.PlainCredentials(username='admin', password='admin')
connection = pika.BlockingConnection(pika.ConnectionParameters(host='127.0.0.1',port=15672,credentials=credentials))

channel = connection.channel()
channel.queue_declare(queue='hello',durable=True)

Error message:

$ python send.py
Traceback (most recent call last):
  File "send.py", line 8, in <module>
    connection = pika.BlockingConnection(pika.ConnectionParameters(host='127.0.0.1',port=15672,credentials=credentials))

Answer 1

@Pigeonnn provided the answer to his own question in his own comment to the original question on this very post:

Actually I've just found a solution. The thing is if you want to listen to rabbitmq you need to connect through port 5672 - not 15672. Changed ports, forwarded and everything works :)

Answer 2

Stating the docs and highlighting the response, RabbitMQ listening ports are:

AMQP:       5672
AMQP/ssl:   5671
HTTP management UI: 15672

Answer 3

first forward the a host port to a guest port on Vagrant in the vagrant configuration file (Vagrantfile). Beware to not utilise a host port that is already used.

Vagrant.configure("2") do |config|
  config.vm.network "forwarded_port", guest: 5672, host: 5671  # Rabbit
end

then connect like so:

credentials = pika.PlainCredentials(username='admin', password='admin')
connection = pika.BlockingConnection(pika.ConnectionParameters(host='127.0.0.1',port=5671,credentials=credentials))

don't forget to configure the user admin accordingly.
