To get started with the CentOS 7.2 installation, we will need the installer ISO file. This can either be the CentOS minimal ISO or the DVD ISO file. If you plan to install just this one server then choose the minimal ISO as it is a smaller, the installer will download the required packages during installation later. I will install several servers with CentOS 7.2, therefore I choose the DVD installer ISO so I dont have to download the same packages again for each server.

  • Download the CentOS 7.2 DVD from a mirror next to you I will use this mirror:

I will do the installation on a vmware virtual machine. The installation steps on a physical server are the same. If your server is not able to boot from an ISO file, burn the ISO on a DVD and insert that into the DVD drive of the server.
