1.3 Configuring a Network Installation Server

If you use a boot ISO or the Preboot eXecution Environment (PXE) to install systems, you can set up a network installation server to host the RPM packages. This server must have sufficient storage space to host the full Oracle Linux 7 installation DVD image (approximately 4.5 GB), and you must configure it to use either NFS or HTTP to serve the image files to the target systems on which you want to install Oracle Linux 7.

To configure a network installation server:

  1. Set up an NFS or HTTP server.

    Instructions can be found in the Administrator's Guide for your Oracle Linux release:

  2. Download the full Oracle Linux 7 installation ISO image.

    See Section 1.2, “Obtaining and Preparing Installation Media”.

  3. Configure the NFS or HTTP server to act as a network installation server.

  4. (Optional) Configure support for installation on PXE clients.

    In deployments where multiple systems are installed, it is common to perform a network-based installation by configuring systems to load a PXE boot image from a Trivial File Transfer Protocol (TFTP) server that is configured on the same network. Dynamic Host Configuration Protocol (DHCP) is used to provide clients with the location of the boot files on the FTP server.

    If you want to support PXE client installation, configure the Dynamic Host Configuration Protocol (DHCP) and Trivial File Transfer Protocol (TFTP) services. See Section 1.3.3, “Configuring DHCP and TFTP Services to Support PXE Clients” or Section 1.3.4, “Configuring Dnsmasq to Support PXE Clients”.
