CentOS幾個版本的區別

當我們下載CentOS 7 時會發現有幾個版本可以選擇，如下： 1、CentOS-7-DVD版本：DVD是標准安裝盤，一般下載這個就可以了。 2、CentOS-7-NetInstall版本：網絡安裝鏡像。 3、CentOS-7-Everything版本：對完整版安裝盤的軟件進行補充，集成所有軟件。 4、CentOS-7-LiveGnome版本：GNOME桌面版。 5、CentOS-7-KdeLive版本：KDE桌面版。 6、CentOS-7.0-livecd版本：光盤上運行的系統，類擬於winpe
其實在README中對這幾種版本做了介紹，以下是原文及其翻譯：

List of images in this directory
================================
CentOS-7-x86_64-DVD-1804.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-x86_64-NetInstall-1804.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-x86_64-Everything-1804.iso
This image contains the complete set of packages for CentOS Linux 7. It can be
used for installing or populating a local mirror. This image needs a 16GB USB
flash drive as it is too large for DVD isos.
CentOS-7-x86_64-LiveGNOME-1804.iso
CentOS-7-x86_64-LiveKDE-1804.iso
These images are Live images of CentOS Linux 7. Depending on the name they use the respective display manager. They are designed for testing purposes and exploring the CentOS Linux 7 environment. They will not modify the content of your hard disk, unless you choose to install CentOS Linux 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-x86_64-Minimal-1804.iso
The aim of this image is to install a very basic CentOS Linux 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.
Using the installation images
=============================
You can burn these images to a DVD or 'dd' them to a USB flash drive.
After the boot media has been prepared, boot the computer off the boot media. If you do an install to your hard disk using these installation images, please remember to run "yum update" after the installation to update your system to the latest packages.
Remember that in order to be able to partition your disk you will need to run
the GUI installer which in turns needs enough RAM. The same is true for the
network setup step. Please refer to the release notes available at
http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 for more details about
these aspects.
