Chapter 2. Requirements

This chapter contains all the requirements for a Red Hat Satellite installation. This includes variations for all database installation types.

2.1. Software Requirements

To perform an installation, the following software components must be available:
Base Operating System
Red Hat Satellite 5 requires a Red Hat Enterprise Linux 6 operating system with the latest packages from the @Base package group and no other package-set modifications, third-party configurations, or software not directly necessary for the operation of the server. This restriction includes hardening or other non-Red Hat security software. If such software is required in your infrastructure, first install and verify a complete working Red Hat Satellite first, then create a backup of the system before adding any non-Red Hat software.
Red Hat Satellite 5 also supports installation on Red Hat Enterprise Linux to supported virtualized environments, including:
  • KVM
  • Xen
  • VMware
Performance on virtualized environments will not always equal the same performance of physical hardware. Make sure to consider your virtual environment's performance and implement any recommended tuning guidelines.

Important

Each purchased Satellite product includes one supported instance of Red Hat Enterprise Linux Server. Install Satellite on a fresh installation of Enterprise Linux where Satellite is the only application and service provided by the OS. Using the Red Hat Enterprise Linux OS included with Satellite to run other daemons, applications, or services within your environment is not supported.
Red Hat Satellite Installation Media
Red Hat provides the installation media as a disc or ISO. It contains an Red Hat Satellite Installation Script, which installs all packages required for Red Hat Satellite.

Important

The Red Hat Satellite Installation Script installs packages beyond the @Base package group. The installation script attempts to download and install these packages but prompts you to install the listed packages manually if they are unavailable. In this situation, either:
  • Install these package from your Red Hat Enterprise Linux installation media, or
  • Subscribe the base operating system to the Red Hat Enterprise Linux channel to resolve package dependencies during installation.
The installation ISO lists the packages necessary for installation in the rhelrpms file located in the updates directory.
Channel content
All software packages and data exported for all entitled Red Hat channels. This content is loaded directly on the Red Hat Satellite after installation using the Red Hat Satellite Synchronization Tool.
Perl interpreter
The installer is a Perl script, and so requires a Perl interpreter. To test if a Perl interpreter is already installed, run the command perl --version. If the output includes the text command not found, install a Perl interpreter.
# yum install perl
