A coworker told me a few weeks ago that he started using Pi-hole to block all advertising and that got me curious. I checked the hardware requirements and already had a server I could install this on. I used CentOS 7.4 as my platform but before starting, make sure selinux isn't running because it isn't supported (It is one of the checks the installation script does). To check execute:

sestatus

If it return enabled change the configuration (see below) and reboot after it has been saved:

vi /etc/sysconfig/selinux, set selinux=disabled

Next make sure your server has a static address before running the installation and then you are ready to install.

I followed their recommended installation command: curl -sSL https://install.pi-hole.net | bash [1] but you can also install everything manually by following the steps here as Method 1 or 2.

The installation was pretty straight forward and it checked for any missing packages and added them to the server. I answered a series of question to setup the Pi-hole DNS server. After the installation you need to point all your clients to your new DNS server (forward internal DNS server to Pi-hole) to take advantage of the blocking capabilities. If you setup the web interface you can login via http://IP/admin and login with the default password provided after the installation (the password can be changed at the command line with: sudo pihole -a -p) or view the statistics via the Dashboard provided by the web server.
