Step-by-Step Guide

1. Update the Package Index
   Open a terminal and update the package index to ensure you have the latest information about available packages:

   sudo apt update

2. Install Erlang
   RabbitMQ requires Erlang to be installed. Add the Erlang repository:

   sudo apt install -y gnupg
   curl -fsSL https://packages.erlang-solutions.com/ubuntu/erlang_solutions.asc | sudo apt-key add -
   echo "deb https://packages.erlang-solutions.com/debian $(lsb_release -cs) contrib" | sudo tee /etc/apt/sources.list.d/erlang.list
   sudo apt update
   sudo apt install -y erlang

3. Add RabbitMQ Repository
   Add the RabbitMQ repository to your system:

   curl -fsSL https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey | sudo apt-key add -
   echo "deb https://packagecloud.io/rabbitmq/rabbitmq-server/debian/ $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/rabbitmq.list
   sudo apt update

4. Install RabbitMQ
   Install RabbitMQ using the apt package manager:

   sudo apt install -y rabbitmq-server

5. Start and Enable RabbitMQ
   Start the RabbitMQ service:

   sudo systemctl start rabbitmq-server

Enable RabbitMQ to start on boot:

   sudo systemctl enable rabbitmq-server

6. Verify RabbitMQ Installation
   Check the RabbitMQ service status to ensure it is running:

   sudo systemctl status rabbitmq-server

If RabbitMQ is running, you should see an active (running) status.

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

   sudo rabbitmq-plugins enable rabbitmq_management

The management interface will be available at http://your_server_ip:15672/.

8. Create an Administrative User
   Create an administrative user for the RabbitMQ management interface:

   sudo rabbitmqctl add_user your_username your_password
   sudo rabbitmqctl set_user_tags your_username administrator
   sudo rabbitmqctl set_permissions -p / your_username ".*" ".*" ".*"

9. Access the Management Interface
   Open your web browser and navigate to http://your_server_ip:15672/. Log in using the administrative user credentials you created.
10. Secure RabbitMQ (Optional)
    For added security, consider setting up SSL/TLS and configuring a firewall to restrict access. Edit the RabbitMQ configuration file: sudo nano /etc/rabbitmq/rabbitmq.conf Add the necessary SSL/TLS configuration parameters. For example: listeners.ssl.default = 5671 ssl_options.cacertfile = /path/to/cacert.pem ssl_options.certfile = /path/to/cert.pem ssl_options.keyfile = /path/to/key.pem ssl_options.verify = verify_peer ssl_options.fail_if_no_peer_cert = true Restart RabbitMQ to apply the changes: sudo systemctl restart rabbitmq-server
11. Monitor RabbitMQ
    You can monitor RabbitMQ using the management interface or by using the rabbitmqctl command-line tool:
    bash sudo rabbitmqctl status
