After three weeks of continuous testing, CentOS project team finally on Mon July 7the 2014 released CentOS Linux 7 for 64 bit x86 compatible systems. This is the first major release for CentOS 7 and actual version is 7.0-1406.

This newly released CentOS 7.0 is an Enterprise-class Linux Distribution built from sources and freely maintained to the public by Red Hat. This release is based on the upstream release of EL7 (Enterprise Linux 7) and most of the packages have been built from source and updated to more recent versions.

    You mentioned : “Upgrade from 6.5 to 7.0 using preupg command” ?
    Can you provide tutorial how to upgrade 6.5 to 7.0
    thanks

    • Ravi Saive says:

      @Gtrhope,
      Yes, I mentioned, but the fact is, the process is very complex and may not work 100%..the only solution is to install a fresh copy of CentOS 7 and move all data from old CentOS 6.5 to 7.0…

  3. Hello Ravi,

    I am a RHEL & Cisco trainer and I got a question for you. What’s the difference between the ” DVD ISO ” and the ” EVERYTHING ISO ” ? Which shall I use and deploy in a production environment ?
    I am profoundly confused which ISO image to download and use. I would request you to enlighten me.

      Suman, here is your answer what the differences are straight from CentOS readme file.

      List of images in this directory
      ================================

      CentOS-7.0-1406-x86_64-DVD.iso
      This DVD image contains all the packages that can be installed using the
      installer. This is the recommended image for most users.

      CentOS-7.0-1406-x86_64-NetInstall.iso
      This is the network install and rescue image. The installer will ask from
      where it should fetch the packages to be installed. This image is most
      useful if you have a local mirror of CentOS packages.

      CentOS-7.0-1406-x86_64-Everything.iso
      This image contains the complete set of packages for CentOS 7. It can be
      used for installing or populating a local mirror. This image needs a dual
      layer DVD or an 8GB USB flash drive.

      CentOS-7.0-1406-x86_64-GnomeLive.iso
      CentOS-7.0-1406-x86_64-KdeLive.iso
      These images are Live images of CentOS 7. Depending on the name they use the
      respective display manager. They are designed for testing purposes and
      exploring the CentOS 7 environment. They will not modify the content of your
      hard disk, unless you choose to install CentOS 7 from within the Live
      environment. Please be advised that you can not change the set of installed
      packages in this case. This needs to be done within the installed system
      using ‘yum’.

      CentOS-7.0-1406-x86_64-livecd.iso
      This is like the GnomeLive image mentioned above, but without packages such
      as libreoffice. This image is small enough to be burned on a CD.

      CentOS-7.0-1406-x86_64-Minimal.iso
      The aim of this image is to install a very basic CentOS 7 system, with the
      minimum of packages needed to have a functional system. Please burn this image
      onto a CD and boot your computer off it. A preselected set of packages will be
      installed on your system. Everything else needs to be installed using yum. The set
      of packages installed by this image is identical to the one installed when choosing
      the group named “Minimal” from the full DVD image.

      I can Enlighten you Suman, Please go back to school and stop calling yourself a RHEL & Cisco Trainer if you cant even figure out how to go to the Cent OS website where the source of all the files came from and learn how to search for and find and read the README files that the Creators of the Distributions so graciously include with their products to Enlighten people with out them having to answer the same questions from thousands of beginner Users.
