2. Introduction

Welcome to the first release of the CentOS-7. CentOS is an enterprise-level Linux release. It is derived from the free source code published by Red Hat1.

CentOS fully complies with the reissuance policy of Red Hat and is committed to fully functional compatibility with upstream products. The modifications made to the components by CentOS mainly remove Red Hat trademarks and art charts.

We have decided not to install the alias from Red Hat. The system administrator can access all "channels" during installation 」.

The first supported upgrade path was provided from CentOS-6 to CentOS-7. This path only supports upgrading from the latest CentOS-6 (6.5 at the time of the deadline) to the latest CentOS-7. For more information about the upgrade procedure, see this page. The tool that provides this function is still being tested and will be released later. If you can assist in the test, refer to the discussion on the CentOS-Devel email list.

Before you try to install or report problems, read other sections.

3. Install 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 stick with dd.

If you do not know which image is applicable, select a DVD image. It allows you to select the components to be installed.

We also have live media images for Gnome and KDE Desktop environments. They allow you to test CentOS by starting a DVD or USB stick. The third livecd image uses Gnome: as the name suggests, this image is smaller than CD. This image does not contain libreoffice. You can also use the live media image to install CentOS on the hard disk, but note that what you install is exactly what you see when using live media. If you want more flexibility when selecting components, use a DVD image.

The netinstall image is applicable to network installation. After the netinstall image is turned on, 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 directly installed through the installer. If you want to install these packages, you must mount the installation media after installing the system, and then copy or install components from there. For most users, it may be easier to install other components using yum install <packagename> after using a DVD image.

4. Check the installation image after downloading

Check their sha256sum before copying the downloaded image to the required installation media.

5. Major changes

As in the first release of each major version, most components have been modified and updated to a newer version. Listing all the changes is beyond the scope of this document. The most significant changes are:

• Update kernel to 3.10.0
• Supports Linux containers
• Ready-to-use with Open VMware Tools and 3D images
• OpenJDK-7 as the default JDK
• Upgrade from 6.5 to 7.0 (as mentioned above)
• LVM snapshots of ext4 and XFS
• Switch to systemd, firewalld, and GRUB2
• XFS as the default file system
• ISCSI and FCoE in kernel space
• Support for PTPv2
• Supports 40 GB Ethernet Card

More data is included here or here.

6. Downgrade

• No, because this is the first release of the CentOS-7

7. Known issues

The list of known upstream problems is included here.

• Many users complain that the new default NetworkManager tool does not enable the Ethernet interface, and must be manually enabled during installation. See CentOS-7 FAQ #2.

• The installer must have at least 406 MB of memory to run. On a system with less than 406 MB, the installer will terminate abnormally. The minimum memory requirement for C7 is 512 MB.

• The CentOS-7 cannot be correctly installed on a VirtualBox Virtual Machine in UEFI mode to an encrypted file system. Unless you modify the command line of the kernel, the system will not ask for a sector password after installation. For details, see the error report.

• If the image resolution is 800x600 or lower, the lower part of the installation screen will be dropped.

8. Fixed issues

• Not in this version
