Reset mysql root password on Ubuntu

Question

如果我有 root 访问权限并且很快关闭数据库不是问题，是否有一种简单的方法可以在 Ubuntu 上设置 mysql root 密码？

Answer 1

If you do not have many tables this should run in 10 seconds.

pass=MyNewPass
echo "ALTER USER 'root'@'localhost' IDENTIFIED BY '$pass';" > mysqlinit
sudo chown mysql:mysql mysqlinit
sudo /etc/init.d/mysql stop
sudo mysqld_safe --init-file=`pwd`/mysqlinit &
sleep 2
sudo killall mysqld
sudo /etc/init.d/mysql start
sudo rm mysqlinit
sql mysql://root:$pass@/mysql

Answer 2

Open your terminal

`sudo mysql -u root
use mysql;
SELECT user, plugin FROM user;
UPDATE user SET plugin = "mysql_native_password" WHERE user = "root" ;
exit
service mysql restart`
