Deploying a system using PXE

PXE, or Preboot eXecution Environment, allows you to instruct computers to boot using network resources. This allows you to control a single source to install servers without the need to physically insert cumbersome DVDs or USB sticks.

Getting ready

For this recipe, you will need a fully working RHEL 7 repository.

How to do it…

With this recipe, we'll install and configure PXE boots from the RHEL 7 installation media, as follows:

Install the necessary packages using the following command:
```
~]# yum install -y dnsmasq syslinux tftp-server
```

Configure the DNSMASQ server by editing /etc/dnsmasq.conf, as follows:

# interfaces to bind to interface=eno1,lo # the domain for this DNS server domain=rhel7.lan # DHCP lease range dhcp-range= ...
