Web Sharing Not Starting Up After installing PHP

Question

On Mac OS 10.4.9 on a G4 PPowerbook, using O'Reilly's "Learning PHP and MySQL," my Personal Web Sharing will not start up.
I enabled Apache per their instructions and things seemed fine.. Then I i installed PHP with these commands, sudo vi/etc/httpd/httpd.conf , then %s/#LoadModule php/LoadModule php/. Then %x/#AddModule php/AddModule php/. Then <espcape>:wq. Then
vi ~/Sites/test.php
o
<?php phpinfo() ?>
<escape>:wq
First of all, the test query from the book didn't work quite right, but now my Personal Web Sharing won't start up. It says "starting up." forever.
Help. And if you can't tell, I have extremely limited knowledge of Unix and command lines, etc.
What do I do? Assume I know nothing... : )

Answer 1

The first thing to do is read the Apache error log which will give you more detail about what's gone wrong.
<pre class=command>tail /var/log/httpd/error_log</pre>
The other thing to do is run configtest which might also indicate errors in the configuration:
<pre class=command>sudo apachectl configtest</pre>
although it'll probably tell you the same thing as the error log.
