After window mysql8 forgets the password, reset the password process

1. Precautions for mysql reset password

From mysql8 and after mysql8, mysql cannot be set in the configuration file my.ini skip-grant-tablesfor password-free login.
If mysql8 configures this skip-grant-tables, then the mysql -uroot -p login will not only fail to log in without password, but
will also cause the mysql service to automatically shut down.

2. mysql8 password-free login

(1) First, open the cmd command line as an administrator . If you do not open the following operations as an administrator, an error will occur. (2) If the mysql service has been started, then close it first. (3) Start without a password: If this is displayed, the start is successful.
net stop mysql
mysqld --console --skip-grant-tables --shared-memory

(4) Key step: Open another cmd command line as an administrator.
Enter mysql -uroot -p, when asked to enter a password, you can log in directly without password when you go back to the city.

(5) Then change the password: refer to the second big step in my blog "Change the mysql password" https://blog.csdn.net/qq_41231694/article/details/123800517?spm=1001.2014.3001.5502
