• For CDROMs:
mv /location/of/disk/space/ disk*.iso /publicly/available/directory/
Ensure that the
/publicly/available/directory
directory is exported via NFS via an entry in
/
etc/exports
.
To export to a specific system:
/publicly/available/directory client.ip.address
To export to all systems use an entry such as:
/publicly/available/directory *
Start the NFS daemon (on a Red Hat Enterprise Linux system, use
/sbin/service nfs start
).
If NFS is already running, reload the configuration file (on a Red Hat Enterprise Linux system use
/
sbin/service nfs reload
).
Be sure to test the NFS share following the directions in the Red Hat Enterprise Linux Deployment
Guide.
11.6. Preparing for a Hard Drive Installation
Note
Hard drive installations only work from ext2, ext3, or FAT file systems. If you have a file
system other than those listed here, such as reiserfs, you will not be able to perform a
hard drive installation.
Ensure that you have boot media available on CD, DVD, or a USB storage device such as a flash
drive.
Hard drive installations require the use of the ISO (or DVD/CD-ROM) images. An ISO image is a file
containing an exact copy of a DVD/CD-ROM image. After placing the required ISO images (the binary
Red Hat Enterprise Linux DVD/CD-ROMs) in a directory, choose to install from the hard drive. You can
then point the installation program at that directory to perform the installation.
To prepare your system for a hard drive installation, you must set the system up in one of the following
ways:
• Using a set of CD-ROMs, or a DVD — Create ISO image files from each installation CD-ROM, or
from the DVD. For each CD-ROM (once for the DVD), execute the following command on a Linux
system:
dd if=/dev/cdrom of=/tmp/ file-name .iso
• Using ISO images — transfer these images to the system to be installed.
Verifying that ISO images are intact before you attempt an installation, helps to avoid problems. To
verify the ISO images are intact prior to performing an installation, use an
md5sum
program (many
