Red Hat Subscripion Manager - Registering
Gregg
Registering your RHEL instance with Red Hat is straightforward assuming that you already have an account:
# subscription-manager register --username <your-rh-user> --password <password>
List the available repos or just go with a default:
# subscription-manager list --available# subscription-manager attach --auto
Then you can do your update:
# yum update
