The difference between CentOS “DVD” vs “Everything” ISOs


What is the difference between the DVD ISO and the Everything ISO? These options are presented on the CentOS download page but there is no explanation as to what the difference is.

CentOS sure keeps this information well hidden. Excerpts from this 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.
