RabbitMQ is a widely-used open-source message broker software that facilitates the sending and receiving of messages between distributed systems. While it’s an essential tool for many developers and system administrators, there may come a time when you need to uninstall it from your Ubuntu system.
Whether you’re migrating to a different messaging system or simply cleaning up unused software, this guide will walk you through the process of safely uninstalling RabbitMQ from your Ubuntu machine.
Let’s get started.
Step 1: Stop the RabbitMQ Service
Before uninstalling any software, it’s crucial to ensure that it’s not running.
sudo systemctl stop rabbitmq-server
Step 2: Remove RabbitMQ Packages
Now that the service is stopped, you can proceed to remove the RabbitMQ packages.
sudo apt-get purge rabbitmq-server
Step 3: Remove Additional RabbitMQ Files
RabbitMQ might leave some configuration and log files behind. To ensure a clean uninstallation, remove these files.
sudo rm -rf /var/log/rabbitmq sudo rm -rf /etc/rabbitmq

After uninstalling software, it’s a good practice to update the package database.
sudo apt-get update
