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 - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 3
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 be used. The examples in this paper use AC3001FD, the most specific choice. 3 - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 4
A kickstart file is a collection of instructions and keywords that the Red Hat Linux 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 - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 5
, HP recommends specifying which interfaces the DHCP server will use. Edit /etc/sysconfig/dhcpd by adding the appropriate interface to the DHCPDARGS= line. The entry in /etc/sysconfig/dhcpd should appear as follows: DHCPDARGS=eth0 • Run the following command to ensure that the DHCP service will - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 6
we want associated with it. 9. After modifying /etc/dhcpd.conf, notify the dhcpd server of the changes 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 - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 7
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 - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 8
each binary CD: (cd /mnt/cdrom && tar -cf - .)|(cd /var/ftp/pub/rhl72/i386 && 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 ensure that the kickstart installation can operate correctly. mkdir /var/ftp/pub/kickstart cp ks.cfg - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 9
the default entry affects any clients that may PXE boot and do not have a specific HEX IP address entry in /tftpboot/pxelinux.cfg. In the following example, we to PXE is moved to the top of the boot order. Then the PXE server, through the use of soft links in the /tftpboot/pxelinux.cfg directory, - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 10

Additional configuration for ProLiant BL10e servers The following changes are recommended to optimize the serial port on ProLiant BL10e servers - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 12
## Show login prompt on serial port ## mv /etc/inittab /etc/inittab.sav cat /etc/inittab.sav | awk '{gsub("6:2345:respawn:/sbin/mingetty tty6","6:2345:respawn:/sbin/mingetty tty6\ns0:12345:respawn:/sbin/agetty 115200 ttyS0 vt100"); print}' >> /etc/inittab ## ## Allow root to login on the serial port - Compaq BL10e | Setting up a Linux PXE server and integrating clients - Page 13
service supplies the server with an address that never changes. This assignment eliminates the need to manually configure a static IP address on the server or both systems will have network problems.
