Just to add a little information: you can install phpsysinfo from
Synaptic, etc. Once installed, assuming you are running Apache and PHP, you can
invoke it by pointing your browser at localhost/phpsysinfo

I installed via Synaptic. I think it is really cool.
Friend of mine said there are other programs out there
that do the same thing, and there are, but this is so
easy to install and use. I just added the link to the
program in a secured directory that I assess on the
server and now, all that information is there.

I think people forget that with linux there is ALWAYS
more than one way to do something. But this is simple
and easy to use.

When setting up a server phpinfo() is used to determine all is working.
a simple script is made to access this function:

<?php
phpinfo();
?>

saved as phpinfo.php to the server web root.

To troubleshoot the Mysql data base:

<?php
echo mysql_connect ('localhost','username','password');
?>

normally saved as mysql_test.php will test the mysql server connection
and passwords...

These scripts are considered a large security risk on servers, and
should be removed or renamed to a name a hacker would not consider to
hold such a powerful script. Information about your server can lead to a
hackers missuse of your system. Don't install any php script that can
give your information away on a public server. If you must have the
info, name your scripts wisely.
