What's the difference between mod_php4, mod_php, and php?

Good job.

Yes you can now start creating php pages.

Don't know.  You can check by going to the rc directory for the run-level you
boot into (3 or 5).

cd /etc/rc3.d/
or
cd /etc/rc5.d/

Look for a file that begins with S and ends with httpd (e.g. S56httpd)

S means start
the number tells linux in what order (e.g. S00 starts up before S45)

on my system (RH7.2) I have:
/etc/rc3.d/S80httpd
/etc/rc5.d/S80httpd

If they aren't there, then you will need to create them by using the ln command:

cd /etc/rc3.d; ln -s ../init.d/httpd S80httpd
cd /etc/rc5.d; ln -s ../init.d/httpd S80httpd

WARNING!!!!!

Unless you have upgraded apache to the latest available from RH, then you ARE
vulnerable.  Upgrade immediately to close the hole.
