I'm trying to install a LAMP stack in a fresh red hat server but yum is misbehaving. Being linux illiterate I'm at a loss.

$yum install httpd
Loaded plugins: security
Setting up Install Process
No package httpd available.
Nothing to do

My yum config

$ cat /etc/yum.conf
[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1 

# Note: yum-RHN-plugin doesn't honor this.
metadata_expire=1h

# Default.
# installonly_limit = 3

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

Other stuff in the yum.repos.d dir

$ ls -lah /etc/yum.repos.d/
total 12K
drwxr-xr-x  2 root root 4.0K Feb  4 01:15 .
drwxr-xr-x 59 root root 4.0K Feb  4 01:28 ..
-rw-r--r--  1 root root  561 Mar 10  2010 rhel-debuginfo.repo

What could be going on? I thought "out of the box" RHEL5.5 would be friendlier :)
