I created an install script on an AWS Redhat instance and i'm not trying to use the same script on a base Redhat install.  Nearly every package in my script comes back as No package...  I've expanded my local repos but i've still haven't been able to match the repos I had access to in AWS.  Could this be because I do not have a Redhat subscription and access to the Redhat subscription channels?My experience in Redhat has been limited by always using Amazon Web Services, so I haven't had to deal with a clean install in the past.
Does Redhat subscript provide access to yum repositories?
rhel;yum
The Red Hat subscription just provides access to system updates, you should already have access to the software itself (you just don't get the updates). If you installed from DVD, there should be a yum repo on there that will enable you to install packages from the installation DVD. If you mounted the DVD it /tmp/mnt you can create the following yum repo in /etc/yum.repos.d/:[rhel-dvd]name=RHEL Installation DVDbaseurl=file:///tmp/mnt/Server/enabled=1gpgcheck=1gpgkey=file:///tmp/mnt/RPM-GPG-KEY-redhat-releaseObviously, change /tmp/mnt to wherever you mounted the actual installation disc.That said, if you don't get system updates, you're probably better off just using the analogous version of CentOS (CentOS 5 is RHEL5, CentOS 6 is RHEL 6, etc).
