Convert Redhat 5.5 to Cent OS 5.5 the easy way so you can use YUM

vi /etc/yum.repos.d/CentOS5.repo
Paste in the following:

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
