Here is how to create a MySQL database with out having to remember the syntax:

#!/bin/bash
EXPECTED_ARGS=3
E_BADARGS=65
MYSQL=`which mysql`


Q1="CREATE DATABASE IF NOT EXISTS $1;"
Q2="GRANT INSERT, SELECT, UPDATE, DELETE, CREATE, DROP, ALTER ON '$1'.* TO '$2'@'localhost' IDENTIFIED BY '$3';"
Q3="FLUSH PRIVILEGES;"
SQL="${Q1}${Q2}${Q3}"

if [ $# -ne $EXPECTED_ARGS ]
then
echo "Usage: $0 dbname dbuser dbpass"
exit $E_BADARGS
fi
$MYSQL -uroot -p -e "$SQL"


Just put that into a file, change the permissions and you should be able to create a user and database. You might have to change the "-uroot" if you are on a shared host.
