CentOS Overview

CentOS is a popular open source software distribution of Linux. The main website is https://www.centos.org CentOS can be configured in several different modes. There is a Minimal mode, a few Server modes, a GNOME Desktop installation and a few other modes.

Note: CentOS has a known bug that affects some Vaults. Previously suggested was a workaround which is located here. Instead we now recommend changing BIOS to UEFI to alleviate this issue. The UEFI guide is located at this link

Verify Hardware Recommendations

CentOS documentation regarding hardware recommendations can be found at: https://wiki.centos.org/About/Product . Be sure to verify the hardware requirements for the specific mode of CentOS before the installation.

Install CentOS

Obtain the Installation Image and Uncompress it

CentOS can be downloaded from https://www.centos.org/download. Either the “DVD ISO” or the “Minimal ISO” can be used across all the Vault platforms.

Image Type: The “Minimal ISO” version installs the minimal system which is simply a command line interface from the console. The “DVD ISO” has all of the different modes that can be installed. The selection of the mode is part of the installation process. This article will describe how to download and install the “Minimal” system from the Minimal ISO and the “GNOME Desktop” system from the DVD ISO.

Note: For other ISO download versions click on the “alternate downloads” link on the download page.

Burn the installation image to a USB drive

The easiest way to transfer the installation image to a USB drive is by using software called “Rufus” on Windows or “Etcher” on Apple OSX. See this link for detailed instructions on how to create a bootable USB drive using Rufus or Etcher.

Rufus will ask if you want to burn in “ISO image mode” or “DD image mode”. Use the recommended default of “ISO image mode”

Note: If during install below there are errors such as “dracut timeout” this could be because a USB 3.0 drive was inserted into a USB 2.0 interface on the Vault. This issue seems specific to CentOS. To remedy the situation, simply insert the USB 3.0 drive into a USB 3.0 interface on the Vault and restart the installation.

Note: If using the Vault FW1x, FW2x, or FW4x, be sure to use a USB stick and the USB keyboard with a plug that is relatively skinny.  The 2 USB ports on the Vault are very close to each other and if either the USB stick or the USB keyboard plug is too wide, you will not be able to plug both in at the same time, which will prevent you from doing the installation.
