It is possible that your system does not have the safe_MySQLd Program (for example, I am using the ubuntu operating system, MySQL installed with apt-get). The following method can be restored:

1. Stop MySQLd;
Sudo/etc/init. d/MySQL stop
(You may have other methods. Simply stop running MySQLd)

2. Run the following command to start MySQL without checking its permissions;
MySQLd -- skip-grant-tables &

3. Use the empty password to log on to MySQL as the root user;
MySQL-u root

4. Modify the password of the root user;
MySQL> update MySQL. user set password = PASSWORD ('newpassword') where User = 'root ';
MySQL> flush privileges;
MySQL> quit

Restart MySQL
/Etc/init. d/MySQL restart
You can use the new password newpassword to log on.

The above describes how to reset the root password of MySQL. I hope you can learn more about MySQL syntax and follow MySQL 5.1 reference manual.
