Chapter 2. Requirements

2.1. Software Requirements
2.2. Hardware Requirements
2.3. Disk Space Requirements
2.4. Additional 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.
    • Finally, you can use the system-config-securitylevel-tui command and reboot the system.
  • An available RHN Proxy Server entitlement within your RHN Satellite Server account.
  • An available Provisioning entitlement within your RHN Satellite Server 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. This channel includes the spacewalk-proxy-installer package that contains the configure-proxy.sh installation program required to install RHN Proxy Server.
  • 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) for RHN Hosted users, or the secure sockets layer (SSL) CA certificate password used to generate the parent server certificate for RHN Satellite Server users.
  • Configuration of the system to accept remote commands and configuration management through Red Hat Network if using the deprecated Web UI installation method. Refer to Section 4.2, “RHN Proxy Server Installation Process” for instructions.
