if your host has cpanel its already installed, just look in your cp for the link called "edit databases(phpmyadmin)"
also several other hosts have similar programs. Due to phpmyadmin being a very insecure program many severs have coded it to require a pass of sorts to keep it safe

also just to be on the safer side rename the folder you installed phpmyadmin in and then type its name in this line instead of pma

$cfgPmaAbsoluteUri= 'http://www.yourdomain.com/pma/';

that way to prevent people from here from accessing your db if you had troubles with the hta edit.

ex you name for folder "mysqlprg"

then change that line to
$cfgPmaAbsoluteUri= 'http://www.yourdomain.com/mysqlprg/';
