How To Do A CentOS 6.0 Network Installation (Over HTTP)

Follow me on Twitter

CentOS 6.0 is based on the upstream release EL 6.0 and includes packages from all variants. All upstream repositories have been combined into one, to make it easier for end users to work with.

CentOS 6.0 Network Installation (CentOS 6.0 NetInstall) is basically installing from a very small downloaded ISO image which downloads the needed files to complete the full operating system installation on-the-fly. This tutorial shows the process of installing CentOS 6.0 using the HTTP NetInstall method. This method is much faster for basic systems since you don't have to download ISO files or one huge DVD based ISO just to get started. If you are installing many systems you may want to look into the stand-alone DVD as it will save time in the end.



This tutorial shows how you can install a fresh copy of CentOS 6.0 by using network installation method. I do not issue any guarantee that this will work for you!
