1. Translations

Translations of these release notes are available for the following languages:

2. Introduction

Hello and welcome to the first CentOS-7 release. CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by Red Hat1.

CentOS conforms fully with Red Hat's redistribution policy and aims to have full functional compatibility with the upstream product. CentOS mainly changes packages to remove Red Hat's branding and artwork.

We have decided not to follow Red Hat's usage of Installation Codes. All 'channels' are available to the System Administrator at time of installation.

For the first time, there is a supported upgrade path from CentOS-6 to CentOS-7. This path is only supported from the latest version of CentOS-6 (being 6.6 at the time of writing) to the latest version of CentOS-7. For more information on the upgrade procedure please take a look at this page. The tools needed for this functionality are still being tested and will be released at a later time. If you can help with the testing, please see this CentOS-Devel mailing list thread and this wiki entry.

Please read through the other sections before trying an install or reporting an issue.

3. Install Media

Various installation images are available for installing CentOS. Which image you need to download depends on your installation environment. All of these images can either be burned on a DVD or dd’ed to an USB memory stick.

If you are unsure which image to use, pick the DVD image. It allows selecting which components you want to install.

Live media images are also available, both for Gnome and KDE desktop environments. These allow you to test out CentOS by booting from the DVD or USB stick. The third livecd image uses Gnome, and as the livecd name implies, it is small enough to fit on a CD. This image does not contain libreoffice. You can also install CentOS to your hard disk from the live media images, but please note that what gets installed on your hard disk is exactly the same as you see when using the live media. For more flexibility in selecting which packages you want to have installed, please use the DVD image.

The netinstall image can be used for doing installs over network. After booting the computer with the netinstall image, the installer will ask where it should fetch the packages to be installed.

The everything image contains all the packages that are available for CentOS-7, including those that are not directly installable from the installer. If you want to install those other packages, you must mount the install media on your installed system after the installation, and copy or install the packages from there. For most users installing from the DVD image and then installing the other packages with ”yum install <packagename>” instead is probably easier.

4. Verifying Downloaded Installation Images

Before copying the image to your preferred installation media you should check the sha256sum of the downloaded installation images.

11. How to help and get help

As a CentOS user there are various ways you can help out with the CentOS community. Take a look at our Contribute page for further information on how to get involved.

11.1. Special Interest Groups

CentOS consists of different Special Interest Groups (SIGs) that bring together people with similar interests. The following SIGs already exist:

And we encourage people to join any of these SIGs or start up a new SIG, e.g.

11.2. Mailing Lists and Fora

Another way you can help others in the community is by actively helping and resolving problems that users come up against in the mailing lists and the fora.

11.3. Wiki and Website

Even as an inexperienced CentOS user we can use your help. Because we like to know what problems you encountered, if you had problems finding specific information, how you would improve documentation so it becomes more accessible. This kind of feedback is as valuable to others as it would have been to you so your involvement is required to make CentOS better.

So if you want to help out and improve our documentation and Wiki, register on the Wiki or subscribe to the centos-docs mailing list.

13. Thanks

We thank everyone involved for helping us produce this product and would like to specifically acknowledge the extra effort made by the QA Team. Without them working lots and lots of hours we couldn't have released this Release as fast as we did. A special thanks also goes to the CentOS-community, who was very helpful in the public QA-run and the TM-hunt. A more complete list of the contributors to this release can be found at /usr/share/doc/centos-release/Contributors of your new CentOS-7 installation.
