Getting started with rabbitmq

Remarks#

This section provides an overview of what rabbitmq is, and why a developer might want to use it.

It should also mention any large subjects within rabbitmq, and link out to the related topics. Since the Documentation for rabbitmq is new, you may need to create initial versions of those related topics.

Installing RabbitMQ on Ubuntu Server

A quick note before actually installing RabbitMQ: Ubuntu 14.04’s Erlang packages have issues if you are using SSL with RabbitMQ, so you’ll need to install a newer version than what the Ubuntu package maintainers provide, so use the binaries at https://www.erlang-solutions.com/resources/download.html, for Erlang 17.0 or higher.

Add RabbitMQ to the package repositories list:

echo 'deb https://www.rabbitmq.com/debian/ testing main' |
    sudo tee /etc/apt/sources.list.d/rabbitmq.list

And then add the signing key:

wget -O- https://www.rabbitmq.com/rabbitmq-release-signing-key.asc |
    sudo apt-key add -

Then update and install:

sudo apt-get update && sudo apt-get install rabbitmq-server

RabbitMQ ‘Hello World’

This code create a producer which send two messages to a queue, and a consumer which receives all the messages from that queue.

Code for producer.py (using the pika 0.10.0 Python client):

import pika

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

channel.queue_declare(queue='queueName')

channel.basic_publish(exchange='',
                      routing_key='queueName',
                      body='Hello')
channel.basic_publish(exchange='',
                      routing_key='queueName',
                      body='World!')
print("Message sent")
connection.close()

Code for consumer.py:

import pika

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

channel.queue_declare(queue='queueName')

def callback(ch, method, properties, body):
    print("Received message: %r" % body)

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

print('Waiting for messages...')
channel.start_consuming()

The output is:

$ python receive.py
Waiting for messages...
Received message: 'Hello'
Received message: 'World!'
