RHEL 6.1: The Certificate-based RHN

If upgrading from RHEL 6 to RHEL 6.1, you would like to use the new subscription system:
For a first-time certificate-based RHN registration:

1. Run the command

   subscription-manager register
   

2. Log into https://access.redhat.com/management/consumers/

   1. Click on the registered system in the consumer list
   2. Find the list of available subscriptions
   3. Subscribe to the relevant subscriptions

3. Run the command

   subscription-manager subscribe --auto
   

4. Run the command

   yum update
   

and all subscribed repos will be configured

With the certificate-based RHN, additional channels are not added through manual configuration. Additional rpm repositories are listed in /etc/yum.repos.d/redhat.repo, but are disabled by default. Yum install using the --enablerepo option and notice that the repositories may look different based on the installed product.

$ yum --enablerepo=rhel-6-server-optional-rpms install php-process

RHEL 6.0: The classic RHN

• Log into Red Hat Network
• Click on “Channels” in the menu bar.
• Click “ Red Hat Optional Server 6”, “target systems” and enable this channel for your server

RHEL 6 and CentOS 6: EPEL

Some of the listed rpms are only available through EPEL. Extra Packages for Enterprise Linux (EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL).
http://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F

$ rpm -Uvh http://fedora.uib.no/epel/6/x86_64/epel-release-6-5.noarch.rpm

Best practice will be to disable EPEL by default and only enable for specific rpm installs with the yum option “--enablerepo=epel”. To disable it, set “enabled=0″ in “/etc/yum.repos.d/epel.repo”
