Obtain CD or DVD for CentOS

These guidelines are only pointers to the CentOS media. Please be aware that the location may change without warning.

  • Go to http://www.centos.org/
  • On the top bar, click on "Downloads".
    • On the pulldown, click on "Mirrors".
    • Look down the page for the "CentOS Public Mirror List"
    • Select a mirror in your country or geographical area.
    • Click on the "HTTP" button for that mirror.
  • Click on the correct OS version.
    • 5.8 for TUSK 4 or OpenTUSK 4 servers or virtual guests.
    • 6.3 for KVM virtualization servers for TUSK or OpenTUSK
  • Click on "isos"
  • Click on the correct architecture
    • x86_64 for TUSK 4 or OpenTUSK 4 servers or virtual guests
    • x86_64 for KVM virtualiztion servers
    • i386 is *only* for the older TUSK 3.12 or earlier partners with older versions of TUSK.
  • If you want all the DVD or CD ISO images and Bittorrent is not blocked by your local firewalls, download the Bittorrent file. This is much faster than most direct downloads.
    • Get the DVD images if at all possible, it makes it easier 
    • Burn DVD's from the ISO images with your favorite local software
    • Make sure you burn the ISO image to the DVD, not make a DVD with the ISO image file contained on it.
  • If your bandwidth or time is limited, directly download the "CentOS-[version]-netinstall.iso" file instead of the full DVD's.
    • Burn that netinstall.iso file to a CD with your favorite local software.
    • Make sure you burn the ISO image to the CD, not make a CD  with the ISO image file on it.

Network Installation

With the DVD's, you will have the option to install the operating system with no active network and use only the DVD's. If you have a working local network with access to the Internet or a local CentOS mirror, you can use the network installation CD, or the first CD or DVD of the set.

To do network based installations, you'll need the URL of the nearest CentOS mirror.

  • Use the directions above to find the nearest CentOS mirror.
    • Select on the latest verson of the OS you want.
    • Select the "os" directory.
    • Select the architecture you want, usually "x86_64".
    • Record this URL
  • Boot with the CD.
  • Select to "Install" the server or guest OS.
    • When asked for the location of the media, put in the OS URL recorded above.
  • Proceed with the rest of your installation, documented at Install RHEL or CentOS
  • No labels
