Chapter 2.
Requirements
These requirements must be met before installation. The Satellite itself must be of a version greater
than or equal to the version of the Proxy that you are trying to install. For example, if you want to install
RHN Proxy Server 5.1, the Satellite version should be 5.1 or later, and can not be 5.0 or lower.
2.1. Software Requirements
To perform an installation, the following software-related components must be available:
• Base operating system — RHN Proxy Server is supported with Red Hat Enterprise Linux AS 4
or Red Hat Enterprise Linux 5. The operating system can be installed from disc, local ISO image,
kickstart, or any of the methods supported by Red Hat.
Note
Each purchased RHN Proxy product includes one supported instance of Red Hat
Enterprise Linux Server. RHN Proxy must be installed onto a fresh installation of
Enterprise Linux where RHN Proxy is the only application and service provided by
the OS. Using the Red Hat Enterprise Linux OS included in RHN Proxy to run other
daemons, applications, or services within your environment is not supported.
Each version of Red Hat Enterprise Linux requires a certain package set to support RHN
Proxy Server. Adding more packages can cause errors during installation. Therefore, Red Hat
recommends obtaining the desired package set in the following ways:
Note
For kickstarting, specify the following package group: @Base
For installing Red Hat Enterprise Linux via CD or ISO image, select the following
package group: Minimal
Warning
If you are running Red Hat Enterprise Linux AS 4, Security-enhanced Linux (SELinux)
must be disabled prior to installation of RHN Proxy Server. If you use Red Hat
Enterprise Linux 5 Server, SELinux can be left enabled when installing RHN Proxy
Server.
You can disable SELinux in one of several ways:
• During CD or ISO image installation, select Disabled when presented with options
for SELinux support.
• To do this for kickstart installation, include the command selinux --disabled
• After the installation is complete, edit the /etc/selinux/config file to read
SELINUX=disabled and reboot the system.
