General Information

In order to install an OS via PXE boot, a TFTP and DHCP server are required.
Using PXE allows for clients to begin a network installation without any net-install ISO.

Checklist

• Distro: Enterprise Linux 7
• Installation Server Created (NFS/HTTP/FTP) that is hosting the install DVD and kickstart file

  yum install tftp-server xinetd

  vim /etc/xinetd.d/tftp
  service tftp
  {
    ....some other variables...
    disable = no

  }

• Start and Enable xinetd

  systemctl start xinetd
  systemctl enable xinetd
