1. translation###
This release note is available in the following languages:
2. Introduction###
Welcome to the first release version of CentOS-7. CentOS is an enterprise-level Linux distribution, which is derived from the free and open source code of Red Hat1.
CentOS fully complies with Red Hat's redistribution policy and strives to be fully functionally compatible with upstream products. CentOS's modifications to components are mainly to remove Red Hat's trademarks and artwork.
We have decided not to follow Red Hat's installation alias. The system administrator can access all "channels" during installation.
For the first time, a supported upgrade path is provided from CentOS-6 to CentOS-7. This path only supports upgrading from the latest version of CentOS-6 (6.5 at the time of writing) to the latest version of CentOS-7. More information about the upgrade procedure can be found on this page. The tool that provides this feature is still being tested and will be released later. If you can assist with the test, please refer to the discussion on the CentOS-Devel mailing list.
Before you try to install or report a problem, please read the other sections.
3. Installation media###
CentOS provides different installation images. The image you need depends on your installation environment. These images can be burned on a DVD or written in a USB memory stick with dd.
If you are not sure which image is suitable, please select DVD image. It allows you to choose which components to install.
We also have live media images of Gnome and KDE desktop environments. They allow you to test CentOS by booting from a DVD or USB stick. The third livecd image uses Gnome: as the name suggests, this image is small enough to fit on a CD. The image does not contain libreoffice. You can also use live media images to install CentOS on your hard drive, but please note that what you installed is exactly what you see when using live media. If you want more flexibility in selecting components, please use DVD images.
The netinstall image is suitable for installation on the network. After booting with the netinstall image, the installer will ask where to download the installed components.
The everything image contains all the components provided by CentOS, including those that cannot be installed directly through the installer. If you want to install these packages, you must mount the installation media after completing the system installation, and then copy or install the components from there. For most users, use yum install after installing the DVD image
4. Verify the installation image after downloading###
Before copying the downloaded images to the required installation media, you should check their sha256sum first.
