2.1. Software Requirements

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

• Base operating system — RHN Satellite Server is supported with Red Hat Enterprise Linux AS 2.1 Update 5 or later and Red Hat Enterprise Linux AS 3 Update 3 or later only. The operating system can be installed from disc, local ISO image, kickstart, or any of the methods supported by Red Hat but must contain certain packages not included in a standard installation.

  	Important
  	If you plan to obtain Monitoring-level service, you must install your RHN Satellite Server on Red Hat Enterprise Linux AS 3 Update 3. This is the only supported base operating system for Satellites serving Monitoring-entitled systems.

  Each version of Red Hat Enterprise Linux AS requires additional packages to support RHN Satellite Server. Although these requirements may be met by conducting an Everything install, Red Hat this installs packages that if not properly managed could pose security hazards. For this reason, Red Hat recommends obtaining the desired package set in the following ways:

  For kickstarting Red Hat Enterprise Linux AS 3 Update 3, specify the following packages and groups:

  • @ Base

  • @ Server

  • @ Development Tools

  • @ Legacy Software Development

  • perl-CGI

  • perl-Time-HiRes

  For installing Red Hat Enterprise Linux AS 3 Update 3 via CD or ISO image, select the following package groups:

  • Web Server

  • Mail Server

  • Development Tools

  • Legacy Software Development

  Then after operating system installation, register the system with RHN and use the Red Hat Update Agent to install the outstanding packages with the following command:

  up2date perl-CGI perl-libwww-perl perl-URI perl-XML-Parser perl-DateManip / perl-XML-Dumper perl-libxml-enno perl-Parse-Yapp perl-XML-Encoding

  Once updated, delete the Red Hat Enterprise Linux AS 3 Update 3 system profile from RHN, as it will be reregistered during Satellite installation.

  For kickstarting Red Hat Enterprise Linux AS 2.1 Update 5, specify the following package groups:

  • @ Advanced Server

  • @ Base

  • @ Messaging and Web Tools

  • @ Software Development

  • @ Utilities

  • @ Web Server

  For installing Red Hat Enterprise Linux AS 2.1 Update 5 via CD or ISO image, select the following package groups:

  • Network Support

  • Web Server

  • Software Development

  • Advanced Server

  • Messaging and Web Tools

  • Utilities

  This satisfies the base operating system requirements. Unlike Red Hat Enterprise Linux AS 3 Update 3, you do not have to run up2date to install additional packages.

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

• Channel content — All software packages and data exported for all entitled Red Hat channels. This content may be loaded directly on the Satellite after installation using the RHN Satellite Synchronization Tool or obtained from your Red Hat representative if synchronization isn't possible, such as in a disconnected environment.
