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 3 Update 5 or later, or Red Hat Enterprise Linux AS 4 only. The operating system can be installed from disc, local ISO image, kickstart, or any of the methods supported by Red Hat.

  	Important
  	If you plan to obtain Monitoring-level service, you must install your RHN Proxy Server on Red Hat Enterprise Linux AS 3 Update 5 or Red Hat Enterprise Linux AS 4. These are the only supported base operating systems for Proxies serving Monitoring-entitled systems.

  Each version of Red Hat Enterprise Linux AS requires a certain package set to support RHN Proxy Server. Anything more can cause errors during installation. Therefore, Red Hat recommends obtaining the desired package set in the following ways:

  	Note
  	For kickstarting either Red Hat Enterprise Linux AS 4 or Red Hat Enterprise Linux AS 3 Update 5, specify the following package group: @ Base For installing Red Hat Enterprise Linux AS 4 or Red Hat Enterprise Linux AS 3 Update 5 via CD or ISO image, select the following package group: Minimal

  Warning

  Security-enhanced Linux (SELinux) must be disabled in Red Hat Enterprise Linux AS 4 prior to installation of RHN Proxy Server. This may be done 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. Finally, you can use the system-config-securitylevel-tui command and reboot the system.

• An available RHN Proxy Server entitlement within your Red Hat Network account.

• An available Provisioning entitlement within your Red Hat Network account (which should come packaged with your RHN Proxy Server entitlement).

• Access to the Red Hat Network Tools channel for the installed version of Red Hat Enterprise Linux AS.

• All rhncfg* packages installed on the Proxy (from the RHN Tools channel).

• Either the rhns-certs-tools package installed on the Proxy (from the RHN Tools channel) or the secure sockets layer (SSL) CA certificate password used to generate the parent server certificate (such as on an RHN Satellite Server).

• Configuration of the system to accept remote commands and configuration management through Red Hat Network. Refer to Section 4.2 RHN Proxy Server Installation Process for instructions.
