While developing a CMS we don't have phpmyadmin, plesk or cpanel rather a simple cli. So to create a quick DB with a user who has all privileges to the DB and a password to the user just give these commands. I think this method works for mysql too.
$ mysql -u adminusername -p Enter password: mysql> CREATE DATABASE databasename; Query OK, 1 row affected (0.00 sec) mysql> GRANT ALL PRIVILEGES ON databasename.* TO "username"@"hostname" IDENTIFIED BY "password"; Query OK, 0 rows affected (0.00 sec) mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.01 sec) mysql> EXIT Bye $
