When we want to uninstall mysql after installing mysql, the uninstallation is often incomplete, causing problems with the next installation. The following provides a method for ubuntu to uninstall mysql completely.

lab environment##

• Linux: Ubuntu 16:04
• Mysql 5.7

step##

Reminder: Be sure to confirm whether the data in the database is backed up before execution, the data is priceless!

• First execute the following commands in the shell

sudo apt-get autoremove --purge mysql-server*

sudo apt-get remove mysql-server*

sudo apt-get autoremove mysql-server*

sudo apt-get remove mysql-common

sudo rm -rf /etc/my.cnf

• Create a shell script (file) called deleteMysql.sh, the content is as follows

#! /bin/bash

list=`sudo find / -name mysql*`for i in $list

do

sudo rm -rf $i

done

exit 0

• Add execution permission to this script and execute it

sudo chmod u+x deleteMysql.sh

sudo ./deleteMysql.sh
