16.4. Preparing for a Network Installation


Make sure an installation CD (or any other type of CD) is not in your hosting partition's drive if you are performing a network-based installation. Having a CD in the drive may cause unexpected errors.
The Red Hat Enterprise Linux installation media must be available for either a network installation (via NFS, FTP, or HTTP) or installation via local storage. Use the following steps if you are performing an NFS, FTP, or HTTP installation.
The NFS, FTP, or HTTP server to be used for installation over the network must be a separate machine which can provide the complete contents of the installation DVD-ROM or the installation CD-ROMs.


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 directory 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 installation staging server, perform the following steps:
  • Create an iso image from the installation disk(s) using the following command (for DVDs):
    dd if=/dev/ dvd of= /location/of/disk/space/ RHEL5.iso
    where dvd refers to your DVD drive device.
    For instructions on how to prepare a network installation using CD-ROMs, refer to the instructions on the README-en file in disk1.

16.4.1. 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 /
    In this case /export/directory will be a directory that is shared via FTP or HTTP.
  • For CDROMs:
    mount -o loop /location/of/disk/space/ disk X .iso /export/directory/ disk X /
    Do the above for each of the CDROM iso images, for example:
    mount -o loop /var/isos/disk1.iso /var/www/html/rhel5-install/disk1/
Next make sure that the /export/directory directory is shared via FTP or HTTP, and verify client access. You can check to see whether the directory is accessible from the server itself, and then from another machine on the same subnet that you will be installing to.
