Requirements; Software Requirements - Red Hat NETWORK SATELLITE 5.3.0 Installation Manual

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 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, but must provide the @Base package group, as the RHN
Satellite installation program will install the RHN Satellite packages as well as additional Red Hat
Enterprise Linux packages not provided in @Base but are needed for RHN Satellite.
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 5.1 or later. SELinux is a set of secure software policies that implement mandatory
access control to Red Hat Enterprise Linux and other operating systems. SELinux is activated
by default on Red Hat Enterprise Linux 5.1, and now users can have SELinux in enforcing or
permissive mode with the targeted policy set during installation of Proxy or Satellite.
Warning
Security-enhanced Linux (SELinux) on Red Hat Enterprise Linux 4 must be disabled
or in permissive mode prior to installation of RHN Satellite. To do this during CD or
ISO image installation, select Permissive when presented with options for SELinux
support. To do this for kickstart installation, include the command selinux --
permissive or wait for the install to complete, edit the /etc/selinux/config file to
read SELINUX=permissive and reboot the system.
More in-depth coverage of SELinux is available at http://www.redhat.com/docs/. You
may also refer to the Red Hat Knowledgebase article on SELinux and RHN Satellite at
http://kbase.redhat.com/faq/.
• 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.
Note
Additional packages beyond @Base are required to install Red Hat Network Satellite. The
Satellite installer will prompt you to either install the listed packages or ask if you want it
