How To Completely Remove MySQL and phpMyAdmin

Ubuntu 7

In this article, we will guide you through the process of completely removing MySQL and phpMyAdmin from your system. This process is helpful if you want to reinstall these applications from scratch or if you want to clean up your system. Please note that these instructions are specifically for Debian-based distributions.

Quick Answer

To completely remove MySQL and phpMyAdmin from your system, you need to stop MySQL services, remove MySQL and its associated files and folders, remove phpMyAdmin, and clean up the system. Follow the step-by-step instructions provided in the post for detailed guidance.

Overview

MySQL is a popular open-source relational database management system. phpMyAdmin, on the other hand, is a free software tool written in PHP intended to handle the administration of MySQL over the Web. Both are widely used in web development.

Prerequisites

Before we begin, you need to have access to a terminal and root privileges. You can gain root access by typing sudo su in your terminal.

Step 1: Stop MySQL Services

The first thing we need to do is to stop all running MySQL services. This can be done using the following command:

service mysql stop

This command stops the MySQL service. The service command is used to run a System V init script, in this case, mysql. The stop parameter instructs the init script to stop the service.

Step 2: Remove MySQL

Next, we will remove MySQL and all its associated files and folders. This is done using a series of commands:

apt-get remove --purge mysql*
apt-get remove --purge mysql-server mysql-client mysql-common -y
apt-get autoremove -y
apt-get remove dbconfig-mysql
rm -rf /etc/mysql /var/lib/mysql
find / -iname 'mysql*' -exec rm -rf {} \;

Let’s break down these commands:

  • apt-get remove --purge mysql* : This command removes all packages starting with “mysql”. The --purge option is used to remove configuration files as well.
  • apt-get remove --purge mysql-server mysql-client mysql-common -y : This command specifically removes the mysql-server, mysql-client, and mysql-common packages. The -y option is used to automatically answer yes to prompts.
  • apt-get autoremove -y : This command removes packages that were automatically installed to satisfy dependencies for other packages and are now no longer needed.
  • apt-get remove dbconfig-mysql : This command removes the dbconfig-mysql package, which provides an abstraction of the database configuration user interface.
  • rm -rf /etc/mysql /var/lib/mysql : This command forcefully removes the /etc/mysql and /var/lib/mysql directories along with their contents.
  • find / -iname 'mysql*' -exec rm -rf {} \; : This command finds and removes all files and directories starting with “mysql” in the root directory.

Step 3: Remove phpMyAdmin

After removing MySQL, the next step is to remove phpMyAdmin. This can be done using the following command:

apt-get purge phpmyadmin*

The apt-get purge command is used to remove packages and their configuration files. In this case, it removes all packages starting with “phpmyadmin”.

Step 4: Clean Up the System

Finally, we need to clean up the system to remove any remaining dependencies. This can be done using the following commands:

apt-get autoremove && apt-get autoclean

The autoremove command removes packages that were installed by other packages and are no longer needed. The autoclean command removes .deb files for packages that are no longer installed on your system.
