Question

now, I can login the mysql with mysql -uroot -p , then I input my password.

Then I try to do this.

mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | +--------------------+

But when I create database, i get an error:

mysql> CREATE DATABASE newdb; ERROR 1044 (42000): Access denied for user 'root'@'localhost' to database 'newdb'

this is my grants:

mysql> show grants; +------------------------------------------+ | Grants for root@localhost | +------------------------------------------+ | GRANT USAGE ON *.* TO 'root'@'localhost' | +------------------------------------------+

on the terminal with MacOSX. Thanks for any help.

From the docs , GRANT USAGE is a:

Synonym for “no privileges”

Leaving aside the point that this privilege has a confusing name, I'm not sure how/why you have such limited privileges for root, anyway.

What you want for root is GRANT ALL . Even better, leave root as-is and create a different superuser with local-only access to replace root. But do note that, in general, you want to give users only the bare minimum privileges necessary for whatever they need to do.
