How to Reset a Forgotten Password

 

If you have forgotten the root user password for MySQL, you can restore it

with the following procedure:

 

 

1. Take down the mysqld server by sending a kill (not kill -9) to the

mysqld server. The pid is stored in a .pid file, which is normally in the

MySQL database directory:

 

 

kill `cat /mysql-data-directory/hostname.pid`

 

You must be either the Unix root user or the same user the server runs as to

do this.

 

2. Restart mysqld with the --skip-grant-tables option.

 

3. Connect to the mysqld server with mysql -h hostname mysql and change

the password with a GRANT command. See GRANT. You can also do this with

mysqladmin -h hostname -u user password 'new password'

 

4. Load the privilege tables with: mysqladmin -h hostname flush-privileges

or with the SQL command FLUSH PRIVILEGES.

 

Note that after you started mysqld with --skip-grant-tables, any usage of

GRANT commands will give you an Unknown command error until you have

executed FLUSH PRIVILEGES.

 

there's a really good MySQL help file for stuff like this you can download

from www.mysql.com (or else just search the online version on the website).
