RabbitMQ brokers on different machines

Question

The hello world example in the tutorial section of rabbitMQ, asks just to change the hostname with the ip of the different machine. But that isn't working for me. I have tried Binding external IP address to Rabbit MQ server​ but that didn't work. Is there something else that i need to do to the configuration file or the code?

Here is the sending code

#!/usr/bin/env python
import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(
    host='ip_address'))
channel = connection.channel()

channel.queue_declare(queue='hello')

channel.basic_publish(exchange='',
                  routing_key='hello',
                  body='Hello World!')
print " [x] Sent 'Hello World!'"
connection.close()

And my receiving code which I am running on another machine

#!/usr/bin/env python
import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(
    host='ip_address'))
channel = connection.channel()

channel.queue_declare(queue='hello1')

print ' [*] Waiting for messages. To exit press CTRL+C'

def callback(ch, method, properties, body):
    print " [x] Received %r" % (body,)

channel.basic_consume(callback,
                  queue='hello',
                  no_ack=True)

channel.start_consuming()

And the error I am getting is

No handlers could be found for logger "pika.adapters.base_connection"
Traceback (most recent call last):

File "send.py", line 25, in <module>
'ip_address'))

I appreciate for you guys to take the time to help me.

I had to do diff things on local implementation for 2 machines maybe some of them can help you: On server !important: change your node from config file rabbitmq-env.conf to run on machine's network ip restart rabbitmq afterwards

 brew services stop rabbitmq 
 brew services start rabbitmq

*you can find rabbitmq config file with

find / -name rabbitmq-env.conf

In project:

credentials = pika.PlainCredentials(env.RABBITMQ_USER, env.RABBITMQ_PASSWORD)
    connection = pika.BlockingConnection(pika.ConnectionParameters(env.RABBITMQ_IP, port=env.RABBITMQ_PORT, virtual_host='/', credentials=credentials))

The problem is the new rabbitmq access control policy

Please read this : RabbitMQ client can't connect to remote RabbitMQ server

or read this : Can't access RabbitMQ web management interface after fresh install
