    The NFS, FTP or HTTP server to be used for installation over the network must be a seperate machine which can provide the complete RedHat tree — this machine is referred to as RPM- SERVER. Both the RedHat/base/ and RedHat/RPMS/ directories must be available and populated with all files from the two installation CD-ROMs.
  • Page 14 Chapter 1:Steps to Get You Started To copy the RedHat tree from each CD-ROM on a Linux machine, and make this tree available: • Insert CD-ROM 1 and execute the following commands: – mount /mnt/cdrom – cp -var /mnt/cdrom/RedHat /location/of/disk/space Where /location/of/disk/space is a directory you create such as /ex- port/7.2/.

    Section 1.10:Which Installation Class is Best For You? • Your computer must have enough unpartitioned disk space for the installation of Red Hat Linux. • You must have one or more partitions that may be deleted, thereby freeing up enough disk space to install Red Hat Linux.
  • Page 24 Chapter 1:Steps to Get You Started Red Hat Linux provides three different classes, or types, of installations: Workstation A workstation installation is most appropriate if you are new to the world of Linux. It will create a system for your home or desktop use. A graphical, Windows-like environment will be installed.
  • Page 25 Section 1.10:Which Installation Class is Best For You? Note Unlike workstation installations previous to Red Hat Linux 7.0, performing a Red Hat Linux 7.2 workstation installation will not install the network dae- mon xinetd (inet services).
