11.1 Registering your system with RHN

This section assumes you have already obtained a valid entitlement for RHEL 5 on System z,

Select the link named Red Hat Enterprise Linux AS for IBM eServer™ zSeries and IBM

S/390® and create an account. 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 /usr/share/rhn/RPM-GPG-KEY

# rhnreg_ks --username=myuser --password=mypw --profilename=linux01.itso.ibm.com

11.2 Installing and updating packages using yum

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.

Update the cpp package to get the latest security fixes:

# rpm -q cpp

cpp-4.1.1-30

# yum upgrade cpp

Loading "rhnplugin" plugin

Loading "installonlyn" plugin
