The NFS server is called nfsserver (10.0.21.17), the dhcp and the tftp server are on the same server, calledpxeserver (10.0.21.210). These server can reside on different machines.
Here are the packages to be installed:
- system-config-netboot
- system-config-netboot-cmd
- tftp
- tftp-server
- dhcpd
Then mount it in a directory /mnt/f10tmp:
# mkdir /mnt/f10tmp
# mount Fedora-10-i386-DVD.iso /mnt/f10tmp -o loop
Copy the content of /mnt/f10tmp into /mnt/f10.
# mkdir /mnt/f10
# cp -r /mnt/f10tmp/* /mnt/f10
Add the following line in /etc/exports:
/mnt/f10 *(rw,async,no_root_squash)
Then run
# exportfs -va
Configuration of the tftp server on pxeserver
Run system-config-netboot and configure a network installation:
- Oprating system identifier: name of your distribution (Fedora10)
- Description: some desciption!
- Select protocol for installation: choose NFS
- Kickstart: if you have a kickstart file, put the path to it here, if not, leave empty
- Server IP address : 10.0.21.17
- Location: /mnt/f10
Create a New PXE configuration file:
- Hostname of IP Address/subnet: the IP of your hosts
- Operating system: Fedora10 should be there. It is auto-populated from the previous step.
Edit the file /etc/xinetd.d/tftp and change the line containing server_args:
service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot -v -v
per_source = 11
cps = 100 2
flags = IPv4
}
Check that the server is on:
# chkconfig --list tftp
tftp on
If off, set it on:
# chkconfig tftp on
and the start the server xinetd:
# /etc/init.d/xinetd restart
You can test your tftp server with the tftp client from your home directory:
$ tftp pxeserver
get linux-install/pxelinux.0
You should have the file pxelinux.0 in your home directory.
Configuration of the dhcp server on pxeserverEdit the file /etc/dhcpd.conf and add the following lines:
subnet 10.0.21.208 netmask 255.255.255.240 {
range 10.0.21.209 10.0.21.222;
allow booting;
allow bootp;
class "pxeclients" {
match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";
next-server 10.0.21.210;
filename "linux-install/pxelinux.0";
}
}
Even if you have a running dhcp server somewhere, this will work.
Start the dhcp server:
# /etc/init.d/dhcpd restart
Check in /var/log/messages:
Dec 5 11:49:06 pxeserevr dhcpd: Listening on LPF/eth0/00:15:c5:53:fd:f5/10.0.21.208/28
Dec 5 11:49:06 pxeserver dhcpd: Sending on LPF/eth0/00:15:c5:53:fd:f5/10.0.21.208/28
Dec 5 11:49:06 pxeserver dhcpd: Sending on Socket/fallback/fallback-net
Restart now your client (target) pc to boot over the network.
You should see something like this in /var/log/messages:
Dec 5 11:49:32 pxeserver dhcpd: DHCPDISCOVER from 00:04:76:51:2e:d8 via eth0

If it does not work, either disable the firewall (system-config-firewall) on pxeserver or allow port 69 to be accessible to any hosts accessing the tftp server.
If you get an error, please have a look here to fix it.
You will have a prompt to boot either on Fedora10 or on your local installation.
