NOTE: CentOS Enterprise Linux is built from the Red Hat Enterprise Linux source code. Other than logo and name changes CentOS Enterprise Linux is compatible with the equivalent Red Hat version. This document applies equally to both Red Hat and CentOS Enterprise Linux.
The Installation Method screen allows
you to choose whether to perform a new installation or an upgrade.
If you choose upgrade, the Partition
Information and Package Selection
options are disabled. They are not supported for kickstart
upgrades.
Choose the type of kickstart installation or upgrade screen from
the following options:
-
CD-ROM — Choose this option to
install or upgrade from the Red Hat Enterprise Linux CD-ROMs.
-
NFS — Choose this option to
install or upgrade from an NFS shared directory. In the text field
for the the NFS server, enter a fully-qualified domain name or IP
address. For the NFS directory, enter the name of the NFS directory
that contains the RedHat directory of the
installation tree. For example, if the NFS server contains the
directory /mirrors/redhat/i386/RedHat/,
enter /mirrors/redhat/i386/ for the NFS
directory.
-
FTP — Choose this option to
install or upgrade from an FTP server. In the FTP server text
field, enter a fully-qualified domain name or IP address. For the
FTP directory, enter the name of the FTP directory that contains
the RedHat directory. For example, if the
FTP server contains the directory /mirrors/redhat/i386/RedHat/, enter /mirrors/redhat/i386/ for the FTP directory. If the
FTP server requires a username and password, specify them as
well.
-
HTTP — Choose this option to
install or upgrade from an HTTP server. In the text field for the
HTTP server, enter the fully-qualified domain name or IP address.
For the HTTP directory, enter the name of the HTTP directory that
contains the RedHat directory. For
example, if the HTTP server contains the directory /mirrors/redhat/i386/RedHat/, enter /mirrors/redhat/i386/ for the HTTP directory.
-
Hard Drive — Choose this option to
install or upgrade from a hard drive. Hard drive installations
require the use of ISO (or CD-ROM) images. Be sure to verify that
the ISO images are intact before you start the installation. To
verify them, use an md5sum program as well
as the linux mediacheck boot option as
discussed in the Red Hat Enterprise Linux
Installation Guide. Enter the hard drive partition that
contains the ISO images (for example, /dev/hda1) in the Hard Drive
Partition text box. Enter the directory that contains the ISO
images in the Hard Drive Directory text
box.
