Setting up RabbitMQ on Amazon EC2

RabbitMQ is an open source message broker software that implements the Advanced Message Queuing Protocol (AMQP) and Streaming Text Oriented Messaging Protocol, Message Queuing Telemetry Transport, and other protocols via a Plugins.

To get started, provision an Ubuntu 20.04 EC2 instance and connect to it via SSH.

Step 1: Install Erlang

sudo apt update
sudo apt install erlang

Step 2: Add RabbitMQ to Ubuntu

Enable apt HTTPS transport

sudo apt install apt-transport-https

Get RabbitMQ keys

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

Add RabbitMQ Repository (this assumes you’re on focal - Ubuntu 20.04)

echo "deb https://dl.bintray.com/rabbitmq-erlang/debian focal erlang-22.x" | sudo tee /etc/apt/sources.list.d/rabbitmq.list

Step 3: Install RabbitMQ

sudo apt update
sudo apt install rabbitmq-server

Check status. RabbitMQ service is started and enabled after installation.

sudo systemctl status  rabbitmq-server.service

Check if RabbitMQ service is configured to start on boot.

sudo service rabbitmq-server start

If disabled, enable it with

sudo systemctl enable rabbitmq-server

Enable RabbitMQ Management Web Dashboard

sudo rabbitmq-plugins enable rabbitmq_management

This web service listens on TCP Port 15672. Open http://server ip/hostname:15672 in your browser to access the dashboard.

By default, the service creates a user 'guest' account with password ‘guest’. This can only be used when accessing on a localhost.

To login on a network, create an admin user account. See below.

Creating Users

Create user or admin user using the command below

sudo rabbitmqctl add_user <username> <password>

example: sudo rabbitmqctl add_user admin adminpassword

Add tags: administrator, management, monitoring, policymaker

sudo rabbitmqctl set_user_tags <username> administrator

In the above command, the tag ‘administrator’ gives user full management UI and HTTP API access. Non administrator users should not be assigned a tag.

Now, set/grant permissions to the user. This grants the user access to all virtual hosts(vhosts).

sudo rabbitmqctl set_permissions <username> ".*" ".*" ".*"

Login to management dashboard http://server ip/hostname:15672 as admin.

Port Access

To connect to rabbitmq using AMQP 0-9-1 and 1.0 clients with and without TLS, use port 5672 or 5671.

amqp://username:password.<server ip/hostname>:5672//

For management UI, HTTP API access, use port 15672 in your browser http://server ip/hostname:15672.
