Mysqlroot password forgot, change root password

1. Stop MySQL service, CMD Open DOS window, enter net stop MySQL
2, in the CMD Command Line window, go to MySQL installation directory such as E:\Program files\mysql\mysql Server 5.0\bin
Demonstration command:
Enter e: Carriage return,
Enter CD "E:\Program files\mysql\mysql Server 5.0\bin"
Note that double quotation marks are also entered so that you can enter the MySQL installation directory.
3, enter the MySQL security mode, that is, when MySQL up, you can enter the database without entering a password.
The command is: mysqld--skip-grant-tables
4, re-open a CMD command line window, enter mysql-uroot-p, use a blank password to log in to MySQL (Do not enter the password, directly press ENTER)
5, enter the following command to start modifying the root user's password (note: there is a "dot" in the middle of the Mysql.user command)
mysql> Update Mysql.user Set Password=password (' New password ') where user= ' root ';
MySQL forgot the root password after the change password, found that update cannot operate on Password, and reported: ERROR 1054 (42S22): Unknown column ' Password ' in ' Field list '
Great God Answer: Update mysql.user set Authentication_string=password (' 123qwe ') where user= ' root '; The password is replaced with authentication_string.
6, Refresh the permissions table

mysql> flush Privileges;
7, exit
Mysql> quit
So the MySQL Super Admin account Root has been reset, and then in the Task Manager to end the Mysql-nt.exe this process, restart MySQL! (You can also restart the server directly)
After MySQL restarts, you can log in to MySQL with the new root password!
