Chapter 3. Installing Red Hat Linux

If you are not sure how to do this, refer to the Official Red Hat Linux Customization Guide and the

Official Red Hat Linux Reference Guide for more information.

3.7.1.1. 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 Linux CD ROMs) in a directory, choose

to install via NFS. You will then point the installation program at that directory to perform the instal 

lation.

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 per 

forming an installation, use an md5sum program (many md5sum programs are available for various

operating systems). An md5sum program should be available on the same server as the ISO images.

Note

ISO images now have an md5sum embedded in them. To test the checksum integrity of an ISO

image, at the installation boot prompt, type:

boot:

linux mediacheck

Additionally, if a file called

updates.img

exists in the directory from which you install, then it will

be used for installation program updates. Refer to the file

install methods.txt

in the

anaconda

RPM package for detailed information on the various ways to install Red Hat Linux, as well as how

to apply the installation program updates.

Note

You can only have the ISO images for one release of Red Hat Linux in the directory.

3.8. Installing via NFS

The NFS dialog (Figure 3 4) applies only if you are installing from an NFS server (if you booted from

a network or PCMCIA boot disks and selected NFS Image in the Installation Method dialog).

Enter the fully qualified domain name or IP address of your NFS server. For example, if you are in 

stalling from a host named

eastcoast

in the domain

redhat.com

, enter

eastcoast.redhat.com

in the NFS Server field.

Next, enter the name of the exported directory. If you followed the setup described in Section 3.7, you

would enter the directory

/location/of/disk/space/

which contains the

RedHat

directory.

If the NFS server is exporting a mirror of the Red Hat Linux installation tree, enter the directory which

contains the

RedHat

directory. (If you do not know this directory path, ask your system administrator.)

For example, if your NFS server contains the directory

/mirrors/redhat/i386/RedHat

, enter

/mirrors/redhat/i386

.
