Chapter 2.

Requirements

These requirements must be met before installation.

2.1. Software Requirements

To perform an installation, the following software components must be available:

• Base operating system — RHN Satellite is supported with 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. Red Hat Enterprise Linux installations must provide the @Base package

group with no other package-set modifications, and without third-party configurations or software

that is not directly necessary for the direct operation of the server. This restriction includes

hardening or other non-Red Hat security software. If such software is required in your infrastructure,

you must first install and verify a complete working Satellite first, and then make a backup of the

system before adding any non-Red Hat software.

When installing a new RHN Satellite, it is recommended that the latest supported update to Red Hat

Enterprise Linux is installed.

Satellite can be installed on Red Hat Enterprise Linux 5 in any virtualized environment supported by

Red Hat, including Xen, KVM, and VMware.

Note that for production deployments, we recommend that you deploy RHN Satellite as the sole

application running on the underlying physical hardware to avoid contention issues. Also, be aware

that functional support for virtualized environments does not always equal the performance of

running on physical hardware, so you may need to carefully consider your virtualized environment of

choice and any tuning guide lines recommended.

Note

Each purchased RHN Satellite product includes one supported instance of Red Hat Enterprise

Linux Server. RHN Satellite must be installed on a fresh installation of Enterprise Linux

where RHN Satellite is the only application and service provided by the OS. Using the Red

Hat Enterprise Linux OS included with RHN Satellite to run other daemons, applications, or

services within your environment is not supported.

• RHN Satellite supports SELinux targeted policy in enforcing or permissive mode on Red

Hat Enterprise Linux 5. SELinux is a set of secure software policies that implement mandatory

access control to Red Hat Enterprise Linux and other operating systems. Users can have SELinux

in enforcing or permissive mode with the targeted policy set during installation of Proxy or

Satellite.

• Satellite installation disc or ISO — this contains the RHN Satellite Installation Program. All

packages required in order to suport the Program are installed automatically, and require no

intervention from the user.
