Chapter 2. Steps to Get You Started

copied over, the Release Notes will not be available during your installation of Red Hat Enterprise
Linux. The Release Notes are formatted in HTML files located at the root of the disc. Copy the files
to your installation directory. For example:
cp /mnt/cdrom/RELEASE-NOTES*.html /location/of/disk/space/
The Release Notes are also available online from http://www.redhat.com/docs/.
Next, make

or HTTP and verify access from a client.
For NFS, export the directory by adding an entry to
•
/location/of/disk/space client.ip.address(ro,no_root_squash)
To export to all machines (not appropriate for all NFS systems), add:
/location/of/disk/space *(ro,no_root_squash)
Start the NFS daemon (on a Red Hat Enterprise Linux machine, use
). If NFS is already running, reload the configuration file (on a Red Hat Enterprise Linux
start
system, use
/usr/bin/service nfs reload
Be sure to test the NFS share following the directions in the Red Hat Enterprise Linux System
Administration Guide.

FTP and HTTP installations also support a second type of tree structure. To make it easier to access

the contents of the installation CD-ROMs, mount each CD-ROM or ISO image with the following
mount point on the FTP or HTTP server (where X is the number of the CD-ROM or ISO image):
/location/of/disk/space/discX/
For example:
mount -o loop CD1.iso /location/of/disk/space/disc1/
2.6.1. Using ISO Images for NFS Installs
NFS installations can use ISO (or CD-ROM) images rather than copying an entire installation tree.
After placing the required ISO images (the binary Red Hat Enterprise Linux CD-ROMs) in a directory,
choose to install via NFS. You will then point the installation program at that directory to perform the
installation.
Verifying that the ISO images are intact before you attempt an installation will help to avoid problems
that are often encountered during an NFS installation. To verify the ISO images are intact prior to
performing an installation, use an

ISO images have an md5sum embedded in them. To test the checksum integrity of an ISO image, at
