This article will show how to setup a '''PXE boot server''' running on top of a base Ubuntu server. This process will require a DHCP server on your local network. This DHCP server does not necessarily need to be running on the same PXE install server, however, I will have both (DHCP and PXE) on the same Ubuntu server.

For this simple example, I will have the PXE boot server serve up only a [[CoreOS]] install. I will use <code>dnsmasq</code> instead of <code>dhcpd</code>. My local network will be <code>10.0.0.10/23</code>.

* Install the following packages:
$ apt-get install -y tftpd-hpa inetutils-inetd dnsmasq apache2 syslinux syslinux-common

* Make the <code>/etc/default/tftpd-hpa</code> file contain only the following lines:
RUN_DAEMON="yes"
OPTIONS="-l -s /var/lib/tftpboot"

* Add the following line to the <code>/etc/inetd.conf</code> file:
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot

* Start/restart the <code>tftpd-hpa</code> service:
$ service tftpd-hpa restart

* Make the <code>/etc/dnsmasq.conf</code> file contain only the following lines:
domain=coreos.redaptcloud.lan
interface=eth0
dhcp-range=10.0.0.11,10.0.0.50,12h
dhcp-host=ff:ff:ff:ff:ff:ff,10.0.0.10 # eth0 mac addr,ip
dhcp-option=3,10.0.0.1 # gateway
dhcp-boot=pxelinux/pxelinux.0
enable-tftp
tftp-root=/var/lib/tftpboot

* Start/restart the <code>dnsmasq</code> service:
$ service dnsmasq restart

* Setup the tftp boot directory tree for PXE/CoreOS:
$ mkdir -p /var/lib/tftpboot/pxelinux/pxelinux.cfg/
$ ln -s /usr/lib/syslinux/pxelinux.0 /var/lib/tftpboot/pxelinux/pxelinux.0

* Download the latest stable release of CoreOS PXE image:
$ cd /var/lib/tftpboot/pxelinux
$ wget <nowiki>http://stable.release.core-os.net/amd64-usr/current/coreos_production_pxe.vmlinuz</nowiki>
$ wget <nowiki>http://stable.release.core-os.net/amd64-usr/current/coreos_production_pxe.vmlinuz.sig</nowiki>
$ wget <nowiki>http://stable.release.core-os.net/amd64-usr/current/coreos_production_pxe_image.cpio.gz</nowiki>
$ wget <nowiki>http://stable.release.core-os.net/amd64-usr/current/coreos_production_pxe_image.cpio.gz.sig</nowiki>
$ gpg --verify coreos_production_pxe.vmlinuz.sig
$ gpg --verify coreos_production_pxe_image.cpio.gz.sig

* The <code>/var/lib/tftpboot/</code> directory tree should look like the following:
<pre>
/var/lib/tftpboot/
└── pxelinux
├── coreos_production_pxe_image.cpio.gz
├── coreos_production_pxe_image.cpio.gz.sig
├── coreos_production_pxe.vmlinuz
├── coreos_production_pxe.vmlinuz.sig
├── pxelinux.0
└── pxelinux.cfg
└── default
</pre>

* Setup your localhost Apache server to serve up your <code>cloud-config.yml</code> file:
<pre>
$ cat << EOF >/var/www/html/cloud-config.yml
#cloud-config
...
EOF
</pre>

* Create your PXE boot menu:
<pre>
$ cat << EOF >/var/lib/tftpboot/pxelinux/pxelinux.cfg/default
default coreos
prompt 1
timeout 15

display boot.msg

label coreos
menu default
kernel coreos_production_pxe.vmlinuz
append initrd=coreos_production_pxe_image.cpio.gz cloud-config-url=http://10.0.0.10/cloud-config.yml
EOF
</pre>

You should now be able to PXE boot another server on your local network, have you DHCP assign a local IP, and automatically boot up using the CoreOS install.
