How do i change MySql Username/Pass for my Server?

[Derision]

start/run/cmd

mysql -u root

grant all privileges on *.* to fred@localhost identified by 'fred' with grant option;

Edit your db.ini file and change the user and password fields to

user=fred
password=fred

or whaterever user and password you choose. Make sure there are no spaces at the end of any line, i.e. go to each line, press the 'END' key and press backspace if there is a space between the last character of the line and where your cursor is.

Make sure you type the grant command exactly as above, i.e. single quotes around the password (the second 'fred' in my example).
