Hi again
On the server, type mysql, and give the command:
grant all privileges on databasename.* to username identified by 'password';
Change "databasename", "username" and "password" to the values you want.
This will give username access to all tables in the specified database from anywhere.
It is common to not allow access from anywhere. If you want that, try:
grant all privileges on databasename.* to username@135.242.65.281 identified by 'password';
To change the root password:
mysqladmin -u root -p password 'newpassword';
This will ask for the old password first, if it isn't set before, just hit enter.
