Apache won't launch after MySQL install

Question

I just installed PHP and MySQL in order to learn it. I installed PHP and everything worked fine, I tried out some basic PHP functions and then decided to get MySQL so I could do some more advanced functions.
After installing MySQL I couldn't reach my own site through 127.0.0.1, and I entered the terminal and found out that Apache wasn't running, so I gave the command "sudo httpd" and got the following output:
sudo httpd
Processing config directory: /private/etc/httpd/users/*.conf
Processing config file: /private/etc/httpd/users/+entropy-php.conf
[Mon May 15 00:25:24 2006] [warn] module mod_php5.c is already added, skipping
Processing config file: /private/etc/httpd/users/Helena.conf
Processing config file: /private/etc/httpd/users/hulken.conf
Bus error
I have tried both with MySQL stopped and running, but it makes no difference, what should I do?

I've read through the file thoroughly several
times and it is all good, nothing seems to be missing
or be malplaced.
Good, but let's make sure. First, look at the output of this Terminal command:
<pre class="command">grep Documents /etc/httpd/httpd.conf.default</pre>You should get something like this:
<pre class="command">DocumentRoot "/Library/WebServer/Documents"
<Directory "/Library/WebServer/Documents">
Alias /manual/ "/Library/WebServer/Documents/manual/"
<Directory "/Library/WebServer/Documents/manual"></pre>If you don't, or you get an error message, post back with the result. If you get the same thing as what I posted, try swapping the default config file for the one you have now. First do this:
<pre class="command">sudo mv /etc/httpd/httpd.conf /etc/httpd/httpd.conf.cmbak</pre>That will back up the current configuration file. Now, copy the default config file so Apache sees it:
<pre class="command">sudo cp /etc/httpd/httpd.conf.default /etc/httpd/httpd.conf</pre>Try starting the server now:
<pre class="command">sudo apachectl start</pre>If it starts, then it's a configuration problem. If it still crashes (bus error), then look for a crash log for httpd in your Console app. I suspect it'll be in /Library/Logs/CrashReporter. Post back with the contents of the thread that crashed. That might have a clue.
One more thing, post the output of this Terminal command:
<pre class="command">ls -l /etc/httpd/users/*</pre>I'd be looking for a file Apache can't open perhaps.
I haven't made any modifications to
it, it was working fine until I tried it after
installing MySQL.
It's really unlikely to be MySQL. If I had to take a guess right now, I'd say it's a problem caused by installing the PHP5 stuff. I can't think of any reason why MySQL would affect Apache, but because the PHP5 installation is changing Apache's config files, I'd suspect that first.
