accouting

I have installed the following two rpms: freeradius-mysql-2.1.3-1.fc9.i386 and freeradius-postgresql-2.1.3-1.fc9.i386 on my Fedora machine. However, when I tried to configure sql server by using "mysqladmin ...", system says "command not found". Do I need to install anything else (and where I can download them) before executing that command? Thanks a lot in advance.
