RabbitMQ is a powerful and flexible open-source message broker that facilitates communication between different components of a distributed system. In this guide, we will walk through the process of installing RabbitMQ on an Ubuntu server. Follow these steps to set up RabbitMQ and manage users effectively.

Step 1: Install Erlang/OTP

Erlang is a programming language that RabbitMQ is built on. To install Erlang, run the following commands:

sudo apt update
sudo apt install curl software-properties-common apt-transport-https lsb-release
curl -1sLf 'https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/setup.deb.sh' | sudo -E bash
sudo apt update
sudo apt install erlang

Step 2: Install RabbitMQ

Now, let’s install RabbitMQ. Execute the following commands:

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

Step 3: Check RabbitMQ Status

Check if the RabbitMQ service is running and enabled:

systemctl status rabbitmq-server.service
systemctl is-enabled rabbitmq-server.service

Step 4: Enable RabbitMQ Management Plugin

Enable the RabbitMQ Management Plugin to access the web-based management interface:

sudo rabbitmq-plugins enable rabbitmq_management

Step 5: Open Ports for RabbitMQ

Allow traffic on ports 5672 and 15672:

sudo ufw allow proto tcp from any to any port 5672,15672

Step 6: Access the RabbitMQ Management Interface

Visit the RabbitMQ Management Interface in your web browser:

http://[server IP|Hostname]:15672

Step 7: RabbitMQ User Management

Create a new administrative user and set its password:

sudo rabbitmqctl add_user admin password
sudo rabbitmqctl set_user_tags admin administrator

Delete the default guest user (optional):

rabbitmqctl delete_user guest

Change the password for an existing user (e.g., “user”):

rabbitmqctl change_password user strongpassword

Congratulations! You have successfully installed RabbitMQ on your Ubuntu server and configured user management. You can now leverage RabbitMQ’s messaging capabilities for your applications.
