what's wrong? please help, thank a lot

Did you set a password for root? If you did, you should provide it when logging in to MySQL: mysql -u root -p password

It's okay if you haven't specified a password for root in the beginning right after mysql is installed.
But you need to run this:
/usr/local/mysql/bin/mysql_install_db, then using root should have all privileges set to 'Y'.
You _SHOULD_ set a root password later on once you are comfortable with everything.
