Qual é a diferença entre ISOs “DVD” do CentOS e “Tudo”?

Question

Qual é a diferença entre o DVD ISO e o Everything ISO? Essas opções são apresentadas na página de download do CentOS , mas não há explicação sobre qual é a diferença.

    

Answer 1

O CentOS mantém esta informação bem escondida. Trechos deste link :

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 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 ” instead is probably easier.

    

Answer 2

O ISO do "DVD" é pequeno o suficiente para que você possa gravá-lo em um DVD de camada única (~ 4,7Gbyte). O restante do software será baixado pela Internet se você optar por instalá-lo.

CentOS-6.7-i386-netinstall.iso

This is the network install and rescue image. This image is designed to be burned onto a CD. You then boot your computer off the CD.

CentOS-6.7-i386-minimal.iso

The aim of this image is to install a very basic CentOS 6.7 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.

CentOS-6.7-i386-bin-DVD1 (2) .iso

These two dvd images contain the entire base distribution. Please burn DVD1 onto a DVD and boot your computer off it. A basic install will not need DVD2. After the installation is complete, please run "yum update" in order to update your system.

CentOS-6.7-i386-LiveCD.iso

This is a CD live image of CentOS 6.7 designed to be burned onto a CD. You then boot your computer using that CD. The disk can also be used to install CentOS 6.7 onto your computer but without offering any package selection options at install time.

CentOS-6.7-i386-LiveDVD.iso

This is a DVD live image of CentOS 6.7 designed to be burned onto a DVD. You then boot your computer using that DVD. The disk can also be used to install CentOS 6.7 onto your computer but without offering any package selection options at install time.

Lembre-se de que, para poder particionar seu disco, será necessário executar o instalador da GUI, que, por sua vez, precisa de RAM suficiente. O mesmo vale para a etapa de configuração da rede.  As notas de lançamento ( link ) fornecem mais detalhes sobre esses aspectos.
