Hello and Welcome to LinuxQuestions,

You can use your RH server as a PXE boot server to which your nodes connect and boot over the network. Read the following sites for how to configure your server.
PXELINUX
PXE Boot

If there are problems/questions after reading or trying please post them here. Have fun with Linux.

Kind regards,

Eric

i had through the pxeboot
all the 15 steps
but i didnot understand the following step 7:

7) Next we need to configure pxelinux. First create the directory /tftpboot/pxelinux.cfg (and make it world readable). Inside that directory you need to create a number of zero size files (use touch):
01-04-4B-80-80-80-03
C
C0
C0A
C0A8
C0A80
C0A800
C0A800F
C0A800FE
01-04-4B-80-80-80-03

i dont know what it is specifying

Hi,

It means just what it says. You have to create a directory named /tftpboot/pxelinux.cfg and make it world readable (744) with these commands:

Code:

mkdir /tftpboot/pxelinux.cfg
chmod 744 /tftpboot/pxelinux.cfg

assuming you're root of course.

Next you need to create zero size files as indicated with touch like this (inside the /tftpboot/pxelinux.cfg directory of course):

Code:

cd /tftpboot/pxelinux.cfg
touch 01-04-4B-80-80-80-03 (bold will need to be changed to your MAC address
touch C
touch C0
touch C0A
touch C0A8
touch C0A80
touch C0A800
touch C0A800F
touch C0A800FE (calculate hexadecimal IP of you host with the gethostip command and change filenames accordingly)

Hope that helps.

Kind regards,

Eric
