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

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

spacewalk-proxy-installerpackage that contains theconfigure-proxy.shinstallation program required to install RHN Proxy Server. - All
rhncfg*packages installed on the Proxy (from the RHN Tools channel). - Either the
rhns-certs-toolspackage 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.
