To recover the MySQL root Password, please follow these steps:

1. Stop the MySQL server process.

/etc/init.d/mysql stop

2. Start the MySQL process with the –skip-grant-tables option, so that it will not prompt for a password.

mysqld_safe --skip-grant-tables &

displays:

root@sharewiz:/root# mysqld_safe –skip-grant-tables &
