have one or more partitions that may be deleted, thereby freeing up enough disk space to install
Red Hat Enterprise Linux.
To gain a better sense of how much space you really need, refer to the recommended partitioning
sizes discussed in Section 12.19.4, “Recommended Partitioning Scheme” .
11.4. Can You Inst all Using t he CD-ROM or DVD?
Installing from a CD-ROM or DVD requires that you have purchased a Red Hat Enterprise Linux
product, you have a Red Hat Enterprise Linux 5.11 CD-ROM or DVD, and you have a DVD/CD-ROM
drive on a system that supports booting from it.
11.5. Preparing for a Net work Inst allat ion
Ensure that you have boot media available on CD , DVD, or a USB storage device such as a flash
drive.
The Red Hat Enterprise Linux installation media must be available for either a network installation
(via NFS, FTP, or HTTP) or installation via local storage. Use the following steps if you are
performing an NFS, FTP, or HTTP installation.
The NFS, FTP, or HTTP server to be used for installation over the network must be a separate
machine which can provide the complete contents of the installation D VD-ROM or the installation
CD-ROMs.
Note
The Red Hat Enterprise Linux installation program has the ability to test the integrity of the
installation media. It works with the CD / DVD, hard drive ISO, and NFS ISO installation
methods. Red Hat recommends that you test all installation media before starting the
installation process, and before reporting any installation-related bugs (many of the bugs
reported are actually due to improperly-burned CDs). To use this test, type the following
command at the yaboot: prompt:
linux mediacheck
Note
In the following examples, the directory on the installation staging server that will contain the
installation files will be specified as /location/of/disk/space. The directory that will be
made publicly available via FTP, NFS, or HTTP will be specified as /publicly/available/directory.
For example, /location/of/disk/space may be a directory you create called /var/isos.
/publicly/available/directory might be /var/www/html/rhel5, for an HTTP install.
To copy the files from the installation DVD or CD-ROMs to a Linux machine which acts as an
installation staging server, perform the following steps:
Create an iso image from the installation disk(s) using the following command (for DVD s):
dd if=/dev/dvd of=/location/of/disk/space/RHEL5.iso
