discarded, and later when all is tested and working, update the golden image so that all
clones created thereafter are enabled for RHN.
Before using yum for the first time, you must import the Red Hat GPG key and register your
Linux guest with RHN. Use the commands below, substituting your RHN user name,
password, and host name of the Linux guest.
# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
# rhnreg_ks --username=myuser --password=mypw --profilename=linux01.endicott.ibm.com
Now that your system is registered with RHN, you can use yum to keep the system updated.
You can download and install the latest version of a package by running yum with the RPM
package name. You can also specify multiple packages on the command line separated by
spaces. The yum install command installs the package if it is not present, and the yum
upgrade command updates to the latest version if it is already installed. If a package has any
dependencies, yum automatically downloads and installs them for you.
