Creating specific user and database

I'm using your command here: WordPress + Super Cache plugin for Centmin Mod Nginx | wp1.centmincache.com

Code:

mysqladmin -u root -p create domain1v381
mysql -u root -p -e "CREATE USER 'domain1username'@'localhost' IDENTIFIED BY 'yourmysqlpass';"
mysql -u root -p -e "GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, LOCK TABLES, CREATE TEMPORARY TABLES ON domain1v381.* TO 'domain1username'@'localhost'; FLUSH PRIVILEGES;"

To create a database and exclusive user.
This command is not specific to wordpress only right?
It's fine to use it for other php apps? like Xenforo.

Thanks!
