On Linux systems, MySQL is a common relational database management system. But sometimes, we may need to delete MySQL. This article will explain how to delete MySQL on Linux.

Step 1: Shut down the MySQL service

Before deleting MySQL, you need to shut down the MySQL service first. You can use the following command:

sudo systemctl stop mysql

sudo service mysql stop

Step 2: Uninstall MySQL

Uninstalling MySQL requires going through the package manager conduct. You can check if MySQL is installed using the following command:

dpkg -l | grep mysql

If MySQL is already installed, an output similar to the following will be displayed:

ii  libmysqlclient18:amd64        5.5.46-0ubuntu0.14.04.2       amd64        MySQL database client library
ii  mysql-common                  5.5.46-0ubuntu0.14.04.2       all          MySQL database common files, e.g. /etc/mysql/my.cnf

Now, you can uninstall MySQL using the following command:

sudo apt-get remove --purge mysql-server mysql-client mysql-common

This command will delete the MySQL server, client and public files. If you also want to delete the MySQL data directory, please use the following command:

sudo rm -rf /var/lib/mysql

Step 3: Delete the MySQL configuration file

dpkg -L mysql-server

This will display a file list of all installed MySQL servers. If you want to delete the MySQL configuration file, use the following command:

sudo rm /etc/mysql/ -R

Step 4: Delete MySQL users and groups

The last step is to delete the MySQL users and groups. MySQL users and groups can be deleted using the following command:

sudo deluser mysql
sudo delgroup mysql

Now, you have successfully deleted MySQL from your Linux system.
