Set up RabbitMQ message-broker

RabbitMQ is an open-source message-broker software, used for sending and receiving messages using a queue in order to process them asynchronously.

sudo apt install rabbitmq-server

2 Enable plugins

To enable web management UI, enable rabbitmq_management plugin by executing on the command line with sudo:

sudo rabbitmq-plugins enable rabbitmq_management

3 Start

Since it’s not needed every project, and it takes up valuable system resources, it’s preferred to start RabbitMQ manually when needed.

3.1 Start manually (recommended)

Execute on the command line:

sudo rabbitmq-server

The server will run in the foreground, and you can stop it when needed with Control-C.

You can also start it as a service:

sudo service rabbitmq-server start

Other service commands are also available:

sudo service rabbitmq-server status
sudo service rabbitmq-server stop
sudo service rabbitmq-server restart

3.2 Start automatically

If wanted, you can also set it up to start automatically after a reboot.

Execute on the command line:

sudo systemctl enable rabbitmq-server

To stop the server and prevent it from running after a reboot, execute:

sudo systemctl disable rabbitmq-server

To check if the server is enabled to run after a reboot, execute:

sudo systemctl is-enabled rabbitmq-server

Login into the UI with user guest and password guest.

5 Configure in a project

If you need to configure it for a project, API will be available at http://localhost:5672 with the same credentials as mentioned above: user guest and password guest.
