MySQL is an open-source relational database management system (RDBMS) available on Linux, Solaris, macOS, Windows, and FreeBSD. Sometimes, uninstalling the software and a fresh installation is the best solution for resolving bugs, or for fixing compatibility purposes.
In this tutorial, you will learn how to uninstall MySQL on Linux, Windows, and macOS.
Prerequisites
- MySQL installed on Linux, Windows, or macOS system.
- A user account with administrator privileges.
How to Uninstall MySQL {on Linux, Windows, and macOS}?
Depending on the operating system, the process of uninstalling MySQL is different. The sections below show how to uninstall MySQL on Linux, Windows, and macOS, and delete all the associated data.
Uninstall MySQL on Linux
Uninstall MySQL from Linux using the distribution’s default package manager, and the rm command to delete the leftover data. In this tutorial, we will work on Ubuntu, but the instructions for other distros are provided as well.
Follow the steps below:
1. Open a terminal window (Ctrl + Alt + T) and stop the MySQL service and all the related processes. Run the following commands:
sudo service mysql stop
sudo killall -KILL mysql mysqld_safe mysqld
3. Depending on the Linux distribution and package manager you are using, run one of the following commands to uninstall MySQL:
- CentOS, Rocky Linux, and RedHat:
sudo yum remove mysql-client mysql-server -y- Ubuntu and Debian:
sudo apt remove mysql-client mysql-server -y
Run autoremove and autoclean to remove unnecessary packages and clean up the package cache:
sudo apt autoremove -y
sudo apt autoclean -y- Fedora:
sudo dnf remove mysql-client mysql-server -y4. After uninstalling MySQL, the next step is to remove residual data. If you still need the data, make a backup before removing it, or rename the directory.
Rename the /var/lib/mysql directory to keep the data if you ever need it again in the future:
sudo mv /var/lib/mysql /var/lib/mysql_directory_backupAlternatively, remove MySQL-related directories by running:
sudo rm -rf /etc/apparmor.d/abstractions/mysql /etc/apparmor.d/cache/usr.sbin.mysqld /etc/mysql /var/lib/mysql /var/log/mysql* /var/log/upstart/mysql.log* /var/run/mysqld5. Remove the mysql user and delete the mysql group, if it exists. Run:
sudo deluser --remove-home mysql
sudo delgroup mysql
After completing the steps above, you have successfully uninstalled MySQL from your Linux system.
Uninstall MySQL on Windows
Follow the steps below to uninstall MySQL from a Windows operating system:
1. Press the Windows key and search for command prompt. Run the app as administrator.
2. Stop the running MySQL server before uninstalling it. The easiest way to stop it is by using the mysqladmin command which was installed automatically during the MySQL installation. In the command prompt, navigate to the bin folder of the MySQL installation directory. For example, the default path is:
cd C:\Program Files\MySQL\MySQL Server 8.0\bin
After navigating into that path, stop the running server by executing:
mysqladmin -u root -p shutdownThe command asks you for the password and shuts down the running server after confirming it.
3. Next, open the Control Panel. Press the Windows key and search for control panel. Press Enter to open the app.
4. Open Programs and Features. In the list of installed programs, locate MySQL and all related programs. Click each one individually and select the Uninstall option.
Click Yes for each prompt and wait for the wizard to finish.
5. After uninstalling all MySQL components, delete the remaining data directories. Since one of the directories is hidden, make sure to enable the Hidden items option in folder settings.
To do so, open any folder using File Explorer, click the View tab, and check the Hidden items option:
Important: If there is critical data that you may still need, make sure to backup MySQL databases before deleting them.
The directories that you need to remove are:
- C:\Program Files\MySQL
- C:\Program Files (x86)\MySQL
- C:\ProgramData\MySQL
- C:\Users\[YourUsername]\AppData\Roaming\MySQL
6. After you uninstall all the components and delete the remaining directories, restart the computer for the changes to take effect.
Uninstall MySQL on macOS
Follow the steps below to uninstall MySQL on a macOS system:
1. Go to System Settings and click MySQL. Click the Uninstall button to remove MySQL from the system.
2. Click the Launchpad icon in the Dock and type Terminal in the search field. Click Terminal to open a new terminal window.
3. Deleting MySQL removes all its databases. If you have critical data stored in MySQL, make sure to back up your files first.
Use mysqldump to back up your databases to a text file. Run the following command:
./mysqldump -u root -p --all-databases > mysqlbackup.sqlThe output is redirected to the mysqlbackup.sql file.
4. Check for running MySQL processes by running the following command:
ps -ax | grep mysql
Terminate the running processes using the following syntax:
kill [process_id]For example, to kill the ttys001 process from the image above, run:
kill 970915. Remove the default MySQL directory and all the leftover directories and files. Run these commands:
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySQL*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /private/var/db/receipts/*mysql*Removing all the directories is important especially if you want to install an older MySQL version on Mac.
6. Use a text editor to open the /etc/hostconfig file and remove the following line:
MYSQLCOM=-YES-Note: Some versions of macOS don’t have the /etc/hostconfig file, so skip this step if the file doesn’t exist on your system.
After following the steps above, you have successfully uninstalled MySQL from your macOS system and cleaned up unnecessary files.

Вступление
Начиная работать с локальными серверами, делая «притирку» и ища удобный локальный сервер, который будет подходить по всем позициям, приходится периодически удалять, то или иное программное обеспечение. В одной из статей сайта, я рассказывал, как установить веб-сервер MySQL, для работы с базами банных. Здесь будем его удалять.
Итак, задача: полностью удалить MySQL с локальной машины и стереть её пребывание на компьютере.
Исходные данные: на компьютере стоит Windows 7, ранее установлен веб-сервер MySQL 5.7.11, сейчас удаляем MySQL 5.7.11. Покажу три варианта, как удалить MySQL.
Вариант 1, Полностью удалить MySQL вручную
Шаг 1. Идем в Панель Управления→Программы и Компоненты→Удаление и Изменение программы;
Удаляем все программы, которые вы использовали для установки MySQL. В моем варианте это MySQL Installer и MySQL Server 5.7. Для удаления выбираем программу и нажимаем кнопку «Удалить».
Шаг 2.
Идем, в каталог, куда устанавливали MySQL. Скорее всего, это: C: Program Files\MySQL и удаляем всё, что содержит MySQL.
Шаг 3.
Идем, в каталог C:\ProgramData и удаляем папку MySQL (для Windows 7).
Папка ProgramData закрыта для просмотра и чтобы её открыть в Windows 7, вставляем в адресную строку: C:\ProgramData и жмем Enter. Папка откроется для работы. Далее удаляем папки с MySQL.
Примечание: В Windows XP это путь: C:\Documents and Settings\All Users\Application Data\MySQL.
Вариант 2, Автоматическое удаление MySQL
Для автоматического удаления, нам понадобится программа MySQL Installer (в первом варианте мы её удалили).
Чтобы удалить MySQL вместе с аккаунтом root, запускаем MySQL Installer;
Жмем Remove (справа таблицы);
В таблице выделяем, то, что хотим удалить, в моем примере это веб-сервер MySQL 5.7.11 и удаляем по шагам инсталлятора (смотрим фото).
Если Вы ставили больше компонентов MySQL, картинка в окне будет такой:
Инсталятор попросит подтвердить удаление
Начался процесс удаления MySQL
Инсталятор спросит, нужно ли удалять данные из папки ProgramData
Процесс удаления MySQL завершен
На последнем этапе можно удалить и сам инсталлятор MySQL Installer (чекбокс внизу таблицы на следующем фото).
Вариант 3, Удалить MySQL из командной строки
Для разнообразия удалим MySQL из командной строки операционной системы.
Шаг 1.
Из командной строки удаляем службу MySQL. Идем в Пуск→Командная строка в меню пуск. На правой кнопке командной строки запуск сервер от имени Администратора. В строке вводим команду: [sc delete MySQL] (без скобок).
Шаг 2.
Удаляем MySQL через панель или инсталятором (первый или второй вариант), на выбор.
Шаг 3.
Удаляем следы MySQL, то есть, папки содержащие MySQL.
По умолчанию MySQL ставится в папки:
Windows 7: [C:\Program Files\MySQL] и [C:\ProgramData\MySQL]
Windows XP: [C:\Program Files\MySQL] и [C:\Documents and Settings\All Users\Application Data\MySQL].
Чистка реестра Windows
Для успокоения души, поищем следы MySQL в реестре операционной системы (Windows 7).
Вариант чистки реестра Windows 7, опасный
Этим вариантом не следует пользоваться, если вы не представляете, как исправить ошибку.
Откройте реестр Windows 7. Для этого в Меню Пуск→Выполнить, вписываем команду: regedit.
В окне «Редактор реестра» поиском ищем, только раздел, слово MySQL и удаляем его.
Примечание: На фото вы видите, что в реестре нашелся раздел MySQL. Это потому, что я не удалял MySQL Installer и оставил его для примера поиска по реестру.
Вариант 2, безопасная чистка реестра программой CCleaner
Ставим программу «чистильщик Windows», например Defraggler или CCleaner и чистим реестр безопасно. На фото CCleaner.

Introduction
MySQL, owned by Oracle, is one of the most widely used open-source relational database management systems (RDBMS). While it’s beneficial to have MySQL installed to manage databases for various applications, there may come a time when you need to uninstall MySQL from your system. This process may involve a bit more than simply dragging a folder to the trash or using a basic uninstall command. In this guide, we will take a step-by-step approach to completely remove MySQL and all its associated files from your system.
This tutorial will focus on uninstalling MySQL from different operating systems such as Windows, macOS, and Linux. We will provide detailed instructions as well as code examples and expected outputs to ensure a smooth uninstallation process.
Uninstalling MySQL on Windows
To uninstall MySQL from a Windows OS, you need to follow these steps:
- Open the Control Panel.
- Navigate to ‘Programs’ -> ‘Programs and Features’.
- Select MySQL Server from the list and click the ‘Uninstall’ button.
After the uninstallation process is complete, you should remove any remaining service instances. Open up the Command Prompt as an administrator and type the following:
sc delete mysqlIf the service is not named ‘mysql’ on your system, replace ‘mysql’ with the correct service name in the above command.
Delete the remaining files and folders manually. You might find MySQL installed in the ‘Program Files’ or ‘ProgramData’ folder. Ensure that you have shown hidden files and folders, and then delete the MySQL folders:
rmdir /S "C:\Program Files\MySQL"
rmdir /S "C:\ProgramData\MySQL"
rmdir /S "C:\Users\[YourUsername]\AppData\Roaming\MySQL"
Replace ‘[YourUsername]’ with your actual username on your Windows system.
Next, you’ll have to clean any MySQL entries from the Windows Registry. Be cautious when editing the registry and ensure to backup before making any changes. Run the Registry Editor (regedit) and delete the following keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MySQL
HKEY_LOCAL_MACHINE\SOFTWARE\MySQL AB
Uninstalling MySQL on macOS
Uninstalling MySQL on a Mac system is not much different from the process on Windows, but it requires some terminal commands. Here are the steps:
- Open Terminal.
- Stop the MySQL service using the following command:
sudo /usr/local/mysql/support-files/mysql.server stop
Remove the MySQL folder:
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
You should also unload the launch agents that automatic start MySQL:
launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysql.plist
rm ~/Library/LaunchAgents/com.mysql.mysql.plist
Finally, you need to remove the MySQL preferences and cached files:
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*Uninstalling MySQL on Linux
The process to remove MySQL on Linux systems varies between distributions. Here’s a general guide that applies to systems using the `apt-get` package manager (like Ubuntu).
Stop the MySQL service:
sudo service mysql stopRemove the MySQL packages:
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autocleanDelete the MySQL configuration and data files:
sudo rm -rf /etc/mysql /var/lib/mysql
sudo rm -rf /var/log/mysql*And again, you can also remove the MySQL users:
sudo deluser mysql
sudo delgroup mysqlNote that these commands may need to be adapted if you’re using a different package manager like `yum` or `dnf` for Red Hat-based systems or `zypper` for openSUSE systems.
Advanced Uninstallation Tips
If you have custom configurations, you may need to manually search and remove those configurations from your system. Use the following command to search for any remaining MySQL related files:
sudo find / -iname '*mysql*'Carefully check the resulting list and delete the files that are meant to be removed. Make sure not to remove system files essential for other applications.
Conclusion
After following the steps in this tutorial, MySQL should be completely removed from your system. While most uninstalled data and service instances will be cleansed through established processes, checking for residual configuration files is good practice. As always, when dealing with system configurations and uninstalling core software components meticulously, ensure every step is understood and properly executed to avoid unintended consequences.
