Have you tried: flush privileges; after making those changes? Are you
sure that the root account that you were using your password with was
set up with the host as localhost? Perhaps your root account only has
access to the mysql table? Try getting in directly to the mysql
database with just: mysql -uroot mysql, and then try it with mysql -
uroot -proot mysql.
