When we use the database server, we may often need to uninstall and delete some software. This process often occurs not only in the MySQL command line. When we need to complete the uninstallation of MySQL, we need to clear all data, configurations and components related to MySQL. This article will detail how to delete MySQL on Linux systems.

  1. Check if MySQL is running

Before deleting MySQL, we need to check if MySQL is running. If MySQL is running, we first need to stop the MySQL service. We can run the following command to check if MySQL is running:

sudo systemctl status mysql

If MySQL is running, it will display the service running status and details. If MySQL is not running, the output will show that MySQL does not exist or is stopped.

  1. Stop the MySQL service

If MySQL is running, we need to stop the MySQL service to stop all services and processes before uninstalling MySQL.

sudo systemctl stop mysql

This will stop the MySQL service and ensure that all MySQL processes are stopped.

  1. Uninstall MySQL

The easiest way to uninstall MySQL is to use the following command:

sudo apt-get remove mysql-server

This will remove the MySQL server and all related components and configurations and data files. If you just want to remove the MySQL client, use the following command:

sudo apt-get remove mysql-client
  1. Delete MySQL configuration and data files

After uninstalling MySQL from the system, we need to remove MySQL Configuration files and data files. We can use the following command to delete the MySQL configuration file:

sudo rm -rf /etc/mysql/

We can use the following command to delete the MySQL data file:

sudo rm -rf /var/lib/mysql/
  1. Clean up MySQL residual files

After MySQL is uninstalled, some residual files related to MySQL may still be left. We can clean these files using the following command:

sudo find / -iname '*mysql*' -exec rm -rf {} ;

This will recursively search all files in the system and delete all files related to MySQL.

  1. Reinstall MySQL

If you wish to reinstall MySQL, please use the following command:

sudo apt-get install mysql-server

If you wish to reinstall the MySQL client, please Use the following command:

sudo apt-get install mysql-client

Before reinstalling MySQL, please make sure you have deleted the original MySQL files and configuration.

Summary

If you wish to remove MySQL from your Linux system, please follow the above steps. First check if MySQL is running and then stop the service. Use the apt-get remove command to uninstall MySQL. If necessary, you can delete the MySQL configuration and data files and clean up the MySQL residual files. If you need to reinstall MySQL, use the apt-get install command to reinstall the complete MySQL server or client.
