    for PXE functionality. For the PXE server Setting up a Linux PXE server requires an HP ProLiant server and two key software components that provide basic PXE functionality: (1) the DHCP server and (2) the TFTP server. Although the DHCP server and the TFTP server components can reside on separate

    the server for a configuration file that matches the IP address of the machine. If no matches are found, it will attempt to load a file called default. • The configuration file loaded by pxelinux.0 will have instructions on what to do next. Some of the choices include boot to local hard drive, boot

    to boot to PXE. Setting up the PXE server Follow these steps to set up the PXE server: 1. Install Red Hat Linux 8.0 on a suitable HP ProLiant server. Note Refer to the ProLiant server certification matrix, http://h18000.www1.hp.com/products/servers/linux/ hpLinuxcert.html, to determine a suitable

    =eth0 • Run the following command to ensure that the DHCP service will be started at each boot: chkconfig --level 345 dhcpd on 6. Configure xinetd and TFTP services. At this point, the TFTP server should be installed. • Enable the TFTP server by using the chkconfig command line utility as follows

    by using the following method or a similar one: service dhcpd restart Warning Do not run a new DHCP server on a network with an existing one unless you have configured the network for multiple DHCP servers. Running two or more DHCP servers on the same network without taking special precautions

    The following examples explain how to get a Red Hat Linux 8.0 client setup and integrated into the PXE server. When using other Linux distributions, slight changes to the commands and scripts are required. 1. Populate the NFS server with Linux installation files using either of the following methods

    tar -xvf -); eject 2. Place the kickstart file on the NFS server along with Red Hat Linux 8.0 ISO images 1, 2, and 3 to floppy. The initrd.img file contains more drivers than the bootnet.img file. Ensure that the /tftpboot/pxelinux.cfg/rhl80-syslinux.cfg configuration file so that the filenames match

    configuration file a specific HEX IP drive, or hard drive, it will default to PXE. If the hard drive has been partitioned, it may no longer default to PXE even though the hard drive is not bootable. In some large cluster farms, boot to PXE is moved to the top of the boot order. Then the PXE server

Additional configuration for ProLiant BL10e servers The following changes are recommended to optimize the serial port on ProLiant BL10e servers

This assignment eliminates the need to manually configure a static IP address on the server and allows that same network device to be moved easily into an environment

    Appendix b: sample scripts and files For the PXE server This section includes sample configuration files as a reference for the PXE server examples provided throughout the HOWTO. NFS configuration file A typical NFS configuration file, /etc/exports, is similar to the following. /var/ftp/pub *(ro,

    Sample scripts and files to be used as guidelines for creating your own are provided in this appendix. These scripts and files are a necessary part of the PXE installation process. dhcpd.conf script A typical "dhcpd.conf" script for Red Hat Linux 8.0 is similar to the following: ddns-update-style
