Because you installed from source, you want /usr/local/apache2/conf/httpd.conf. The ubuntu package (from APT) uses /etc/apache2/apache2.conf.

I installed Ubuntu 8.10 desktop OS in my VMWare. I also installed Apache2.2.9 using the apache2-2.2.9.orig.tar.gz file.
"ps -ef | grep httpd" shows the result below.
"root 17723 1 0 05:51 ? 00:00:00 /usr/local/apache2/bin/httpd -k start" followed by a couple of lines for the daemon service holding different PIDs. The httpd.pid file under '/usr/local/apache2/logs' shows '17723' as above.

When I stop the service by issuing the command '/usr/local/apache2/bin/apachectl -k stop', I do not find any result for "ps -ef | grep httpd". Neither does
http://127.0.0.1 work. The
httpd.pid file under '/usr/local/apache2/logs' no longer exists.

Excerpt from the error_log file under '/usr/local/apache2/logs':
[notice] caught SIGTERM, shutting down
[notice] Apache/2.2.9 (Unix) configured -- resuming normal operations
Looking at the description above, can I say that Apache is installed correctly?
