Installation guide

rity 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 dir-

ectory that will be made publicly available via FTP, NFS, or HTTP will be specified

as /export/directory. For example, /location/of/disk/space may be a directory

you create called /var/isos. /export/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 in-

stallation staging server, perform the following steps:

• Create an iso image from the installation disk(s) using the following command:

• For DVD:

dd if=/dev/dvd of=/location/of/disk/space/RHEL5.iso

where dvd refers to your DVD drive device.

• For CD-ROMs:

dd if=/dev/cdrom of=/location/of/disk/space/diskX.iso

where cdrom refers to your CD drive device, and X is the number of the disk that you are

copying, beginning with 1 for the first disk, and so on.

5.1. Preparing for FTP and HTTP installation

For FTP and HTTP installation, the iso image or images should be mounted via loopback in the

publicly available directory, in the following manner:

• For DVD:

mount -o loop /location/of/disk/space/RHEL5.iso /export/directory/
