Chapter 4.23InstallationThis chapter describes the initial installation of the RHN Satellite. It presumes the prerequisites listedin Chapter 2, Requirements have been met. If you are instead upgrading to a newer version of RHNSatellite, contact your Red Hat representative for assistance.4.1. Base InstallThe RHN Satellite is designed to run on the Red Hat Enterprise Linux AS operating system. Therefore,the first phase is to install the base operating system, either from disc, ISO image, or kickstart. Duringand after operating system installation, make sure you:• Allocate plenty of space to the partitions storing data. The default location for channel packagesis /var/satellite/. For RHN Satellite with Embedded Database, remember the databaseRPMs go in the /opt/ partition, while the database itself is built in /rhnsat/. Refer to Section 2.2,“Hardware Requirements” for precise specifications.• Enable Network Time Protocol (NTP) on the Satellite and separate database, if it exists, and selectthe appropriate time zone. All client systems should already be running the ntpd daemon and beset to the correct time zone.• Due to potential complications, it is strongly advised that the /home/ partition is locally mounted.4.2. RHN Satellite Installation ProgramThe following instructions describe how to run the RHN Satellite Installation Program:ImportantDue to potential complications, it is strongly advised that the /home/ partition is locallymounted.1. Log into the machine as root.2. Insert the RHN Satellite Server CD containing the installation files or download the ISO imagefrom the RHN website.3. If you are installing from CD, Red Hat Enterprise Linux may automount the CD. If it does so, it willmount the CD to the /media/cdrom/ directory.If Red Hat Enterprise Linux does not automount the CD, manually mount it to the /media/cdrom/ directory with the following command:mount /dev/cdrom /media/cdromIf you are installing from an ISO, mount the file from within the directory containing it using thecommand:mount -o loop iso_filename /media/cdrom
