In this article, we’ll show you a step-by-step guide on how to install and configure a RabbitMQ Server on Ubuntu 22.04 to help you get up and running with this great piece of software.

#Prerequisites

To follow this guide, you need to meet the following set of requirements:

• An instance of Ubuntu 22.04.
• A user with sudo privileges
• Python 3 with pip package manager installed

Step 1: Install the newest version of Erlang

Install required dependencies

Run the following commands to install the required packages.

apt update
apt install curl software-properties-common apt-transport-https lsb-release

Add Erlang Repository

Once you have imported the key, add the repository to your Ubuntu 22.04 system by running the following commands:

curl -1sLf 'https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/setup.deb.sh' | sudo -E bash

Expected command execution output:

Install Erlang on Ubuntu 22.04

The last step is the actual installation of Erlang. Update your system package list and install Erlang:

apt update
apt install erlang

Check Erlang version:

$ erl -eval 'erlang:display(erlang:system_info(otp_release)), halt().' -noshell

Step 2: Add RabbitMQ Repository To Ubuntu 22.04

Team RabbitMQ maintains an apt repository on PackageCloud, a package hosting service. It provides packages for most recent RabbitMQ releases.

Let’s add the RabbitMQ Repository to our Ubuntu system.

curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.deb.sh | sudo bash

Step 3: Install RabbitMQ Server Ubuntu 22.04 LTS

To install RabbitMQ Server Ubuntu 22.04, update the apt list, then install rabbitmq-server package:

apt update
apt install rabbitmq-server

Check status:

systemctl status rabbitmq-server.service

Check RabbitMQ version:

rabbitmqctl status | grep RabbitMQ

Check if the service is configured to start on boot or not:

systemctl is-enabled rabbitmq-server.service 
enabled

If it returns disabled, enable it by running:

systemctl enable rabbitmq-server

Step 4: Check your firewall

After installing RabbitMQ, ufw is enabled and configured by default. If you don’t want that, you can disable it by this command:

ufw disable

Step 5: Enable the RabbitMQ Management Dashboard

You can optionally enable the RabbitMQ Management Web dashboard for easy management.

rabbitmq-plugins enable rabbitmq_management

The Web service should be listening on the TCP port 15672.

Double if the port is listening:

ss -tunelp | grep 15672

By default, the guest user exists and can connect only from localhost. You can point your browser to http://localhost:15672 and login with this user locally with the password “guest”.

To be able to log in on the network, create an admin user like the below:

rabbitmqctl add_user admin Green1234
rabbitmqctl set_user_tags admin administrator

RabbitMQ User Management Commands

Delete User:

rabbitmqctl delete_user user

Change User Password:

rabbitmqctl change_password user Green@1234

Create a new virtual host:

rabbitmqctl add_vhost /my_vhost

List available Virtual hosts:

rabbitmqctl list_vhosts

Delete a virtual host:

rabbitmqctl delete_vhost /my_vhost

Grant user permissions for vhost:

rabbitmqctl set_permissions -p /my_vhost user ".*" ".*" ".*"

List vhost permissions:

rabbitmqctl list_permissions -p /my_vhost

To list user permissions:

rabbitmqctl list_user_permissions user

Delete user permissions:

rabbitmqctl clear_permissions -p /my_vhost user
