MySql forget the root password, update password method

First, avoid close Login Mysql service

1. Run cmd as an administrator to see if mysql has been launched, if already started, stop: net stop mysql.

net stop mysql

2. Switch to the MySQL installation path: D:\environment\mysql-5.7.25-winx64\bin; if already equipped with environment variables, can not switched. At the command line, type:mysqld -nt --skip-grant-tables

mysqld -nt --skip-grant-tables

3. Administrator RestartA cmd command window, type: mysql -uroot -p, do not lose your password to enter directly into the database.

mysql -uroot -p

Second, retrieve password

If you do not want to change your password, just want to see the original password, you can execute the statement from the command lineselect host,user,authentication_string from mysql.user;

 select host,user,authentication_string from mysql.user;

Third, change passwords

In turn execute the following statement at the command line

use mysql
update user set authentication_string=password("123456") where user="root";// 'new_pass' 这里改为你要设置的密码
flush privileges;
quit

Restart MYSQL, enter the password you can!
