While levaraging all of the features provided by cobbler can be relatively simple, the full functionality of this powerful tool is too broad to be documented in this guide. The cobbler community provides documentation at link:++[] to accompany the packages in the Fedora repository.
When a system requests an address during network booting, the DHCP server also provides the location of files to boot. A network should have only one DHCP server.
# wget{PRODVER}/Server/x86_64/os/images/pxeboot/vmlinuz -O /var/lib/tftpboot/f{PRODVER}/vmlinuz
# wget{PRODVER}/Server/x86_64/os/images/pxeboot/initrd.img -O /var/lib/tftpboot/f{PRODVER}/initrd.img
This appendix is intended for users with previous Linux experience. If you are a new user, you may want to install using minimal boot media or the distribution DVD instead.
The kernel is the core of any Linux operating system, and the initramfs provides the kernel with required tools and resources. These files are also provided by tftp.
The examples in this section use the public Fedora mirrors as the package source. For faster installations, installing to many systems, or more isolated environments, you may wish to maintain a local repository.
TFTP Server
Test your configuration and address any problems you discover.
subnet netmask {
if option arch = 00:07 {
filename "uefi/shim.efi";
} else {
filename "pxelinux.0";
subnet netmask {
default-lease-time 600;
max-lease-time 7200;
ddns-update-style none;
Start and enable the `tftp socket`. `systemd` will automatically start the `tftpd` service when required.
Setting Up an Installation Server
Restart the dhcp service to check the configuration and make changes as needed.
# refer to RFC4578 for possible arch option values
option arch code 93 = unsigned integer 16;
PXE Installation Overview

Providing repositories
Providing and configuring bootloaders for PXE clients
Preboot Execution Environment, or PXE, is a techonology that allows computers to boot directly from resources provided over the network. Installing Fedora over the network means you don't have to create media, and you can install to multiple computers or virtual machine simultaneously. The process involves a number of components and features working together to provide the resources required.
