1. Stop the mysqld daemon process.
2. Start the mysqld daemon process with the –skip-grant-tables option.
3. Start the mysql client with the -u root option.
4. Execute the UPDATE mysql.user SET Password=PASSWORD(‘password’) WHERE User=’root’;
5. Execute the FLUSH PRIVILEGES; command.
These steps reset the password for the “root” account to “password”. To change the password for a different account, or to set a different password, just edit the variables in single-quotes in step 4.
If you know your existing MySQL root password, steps 1-3 are not necessary.
