it's saying it thinks port 80 is taken.  lsof is a good program, I 
forget it it's netstat or another that could show you active connections 
to port 80.

which version of apache are you running, is that apache the centos 
version or the apache.org source, what OS version of Centos, and can you 
run ps ax | grep httpd and see if there's another instance of apache 

also do an ls -al /usr/local/apache/logs and/or /var/local/apache/logs 
depending on where you keep these...

yum install multitail will give you a nice program where you can type:

multitail -s 2 /var/log/messages /usr/local/apache/logs/error_log 

it'll display all your logs in real time, and you can use another window 
(or a program like screen) to stop/start apache, and see what it's 
crying about.

If the server is new, maybe yum remove httpd, reboot, yum install httpd, 
your call.
