How do I uninstall MySQL?
I assume that you don't need MySQL anymore and you have already taken backup of your important databases. I suggest you to take backup of your important MySQL databases.
Note: Your all mysql data will be lost.
First make sure that MySQL service is stopped.
sudo systemctl stop mysql
Remove MySQL related all packages completely.
sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-* mysql-client-core-*
Remove MySQL configuration and data. If you have changed database location in your MySQL configuration, you need to replace /var/lib/mysql
according to it.
sudo rm -rf /etc/mysql /var/lib/mysql
(Optional) Remove unnecessary packages.
sudo apt autoremove
(Optional) Remove apt cache.
sudo apt autoclean
all the above solutions are correct but I would try with
sudo apt-get remove --purge mysql* sudo apt-get autoremove sudo apt-get autoclean
This will uninstall all mysql related packages.
This will remove mysql 5.6 from ubuntu 15.04
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo rm -rf /var/lib/mysql
sudo rm -rf /etc/mysql
