#!/usr/bin/env python
import pika

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

#!/usr/bin/env python
import pika

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


channel.queue_declare(queue='hello')

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

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

print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()

## Installation
- Download the erland deb [here](https://packages.erlang-solutions.com/erlang/#tabs-debian)
- Download the server deb [here](https://www.rabbitmq.com/install-debian.html)
- `sudo dpkg -i <erlang.deb> <server.deb>`

## Start the server
`sudo service rabbitmq-server start`

## Check server status
`sudo service rabbitmq-server status`

## Create a virtual environment (I use virtualenvwrapper)
- `mkdir -p /tmp/rabbitmq-helloworld`
- `cd /tmp/rabbitmq-helloworld`
- `mkvirtualenv -i pika rabbitmq`

## Create the scripts (see the other files)

## Start the reciever
`python receiver.py`

## Open a new tab/terminal and start the sender
`python send.py`

## Stop the server
`sudo service rabbitmq-server stop`
