CentOS 7 is a free enterprise-class community supported Linux OS derived from RHEL (Red Hat Enterprise Linux) sources and designed to provide compatibility with RHEL. That is, CentOS aims to provide a free community-supported alternative to paid subscription service of RHEL. Let us take a look at the latest iteration to this very popular Linux distro, CentOS 7.
Mar 12, 2017 - The “Everything iso adds a complete set of packages required for. If you downloaded either of the live media, you get to test CentOS 7 before. Is it possible to install CentOS (7) on a USB drive? If yes, then is it possible in install CentOS in the USB using DVD/everything ISO by selecting USB as the drive in the installation process? Also, will it modify the things on other drive in the installation process to the USB drive? So it can't work if I download CentOS iso on.
CentOS is available for download in 5 different variations. First is the DVD iso (recommended) which is about 4GB in size so you can imagine you’re getting everything. Well not exactly, there is also an “Everything ISO” which is over 7GB big. The “Everything iso adds a complete set of packages required for populating a local mirror. If either of these is too big for you, you can go for everyone’s favorite, a live edition(Gnome or KDE). The live editions allow you test-drive CentOS without modifying your local disk before choosing to install the distro.
There is also a Minimal iso (without a GUI) which provides just the packages required for a functional system in less than 700MB and a net install iso which also doubles as a rescue image. The net install iso is very useful if you already have a local mirror in place. NB. All these are available ONLY in 64-bit editions.

After download, you can burn the iso to either a CD/DVD or USB using a dedicated tool such as Rufus/Unetbootin or dd if you know how to. You can then boot the PC off the boot media. If you downloaded either of the live media, you get to test CentOS 7 before installation.
If you have used Fedora before, you’ll find out you have the same installer provided. You set things like date and time, keyboard layout, language and support, disks and partitions and then your software selections.
Then you set up your root password and user account.
If you are setting it up to use as a server, which it excels at, you can set up your server details also in your installation setup. You will also have to accept the license information before you can use the distro.
The process is pretty straightforward albeit not the simplest.
After installation, run yum update to obtain the latest packages.

Depending on your choice of Desktop Environment, you’ll boot up to something familiar. We decided to go with the Gnome edition. You may even log into your cloud accounts in your initial Gnome setup. There is support for Google, ownCloud and Windows Live.
By default, the Gnome edition boots into the Classic desktop mode. If you prefer Gnome 3 like I do, all you have to do is log out and selecting the Gnome 3 from the settings before re-logging in which I quickly do. What you have is a typical Gnome desktop with all of its modern beauty and appeal.
So depending on your choice of iso, you get a differing set of applications available by default. The minimal iso packs just the basics. The live editions pack some more applications but for the full set, you need the DVD editions. You can choose stuff like Basic Web Server, Server with a GUI, GNOME and KDE desktops. These environments also come with extra add-ons which you choose to install.
You can also select the software to be installed right from the setup installation process. Mozilla Firefox is provided as the default browser, there is LibreOffice for all your Office needs and Rhythmbox for your music. Other software applications provided include Gedit as the default text editor, Boxes for virtualization, Brasero, Empathy and Evolution for chat and email needs, Cheese webcam and more. For applications that are unavailable by default, you can easily install them with the Gnome Software Manager.

CentOS 7 excels at what it does well, server side stuff. It is the kind of distro you can pretty much set it up and have it running for a long time without any issues making it a favorite for Server OS needs. It is not popular amongst desktop users although it works quite well. It will need a little tweaking and some more installation especially if you choose the live edition over the DVD. The installer might be a bit intimidating and daunting and could use a bit of improvement. Regardless, you have an awesome community to fall back on should you encounter any issues whatsoever.

With CentOS 7, you have the power to run all forms of server needs with which it excels. Then again, you also have the ability to run it as a desktop OS quite capable.

If you are intrigued, you should definitely try it out. Do you use CentOS 7? Have you ever tried it? Share your thoughts and comments with us in the comments below and thanks for reading.
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.

Centos 6 Iso Download
The 'DVD' ISO is small enough that you can burn it to a single-layer DVD (~4.7Gbyte). The rest of the software will be downloaded via the Internet if you chose to install it.

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. The release notes ( http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.7 ) provide more details about these aspects.
