Mysql Forget root password how to do _mysql

MySQL sometimes forget the root password is a sad thing, in this case, how to reset the root password it?

Locate and edit the MySQL my.ini configuration file and add skip-grant-table to the Mysqld node. as follows:

# This let you safely reset the lost root password.
Skip-grant-table

Save the changes and restart the MySQL service.

You can now connect to the database without the root password. Then perform the following update:

Use MySQL;
UPDATE USER
SET password = password (' yournewpasswordhere ')
WHERE USER = ' root ' and
host = ' localhost ';

So the root password is modified, this time, the My.ini in the skip-grant-table Delete, and then restart the MySQL service

The following is a description of the password reset method under Windows and Linux.

Windows:

1. Log in as a system administrator.
