Before doing any kind of task first we have to install RabbitMQ.

RabbitMQ Installation

Here is a step-by-step guide on how to install RabbitMQ:

1. As there are so many commands to run, I am creating a shell script to ease this process. To create a shell script open the terminal and run this command.

touch rabit.sh;nano rabbit.sh

it will create a file named rabbit.sh and open it on the nano text editor.

1. Paste the following code on the rabbit.sh. As my system is **Debian-**based and the version name is Bookworm, I am changing some things while adding the source list directory. You can find what should you change based on your distro on the official RabbitMQ documentation.

#!/bin/sh

sudo apt-get install curl gnupg apt-transport-https -y
