How to Install Linux Distro CentOS
CentOS is an industrial used operating system Linux distrobution, that was meant to replace Red Hat. Installing CentOS isn't that difficult if you follow this guide. This is from my experience and I got it to work fine.
What is CentOS?:
First, what is CentOS? Well CentOS is a linux distro (short for distribution). Linux is the new form of Unix, which was the old language used to create operating system. I would like to say that CentOS is also a successor to Red Hat, a popular distro for enterprise uses. This is the CentOS logo, just in case you can't find the correct one (it may have changed, but it should look similar still).
Now lets move on to this quick how can I install centOS. For a disclaimer I installed this OS (operating system) onto my laptop which is a Sager/Clevo, model: this one.
Why Use or Learn CentOS?:
CentOS is widely used in the industry because of its capabilities of running minimal and requiring minimal hardware specifications. CentOS is mostly used as a server operating system using Apache software or for setting up systems as monitoring devices or security. Learning CentOS and Linux commands will also give you a boost for your tech skills as Linux is actually much more robust than Windows in terms of customizability.
The Steps (in chronological order):
1. First this entire how to, I hope you have a USB 2.0 drive or better with more than 16GB of storage. Make sure the USB drive is also empty and has nothing on it, because it will be wiped.
2. Now go to the website and download any image file you want (for this tutorial I downloaded the everything image file).
3. Once that's downloading you can download the USB Tool we will use to help create a bootable drive for us. I used Fedora Live USB Tool (I also used this for Korora another Linux distro).
4. When your download finishes it would be a good time to check your disk management. If you are on a Windows operating system go to start and type diskmgmt. Now you can right click on a volume and shrink it. If you already have free space on the hard disk drive or solid state drive you want to install it on, then you don't have to shrink it. I suggest you install CentOS in a drive or partition that is greater than 60 GB.
5. Once you install the USB Tool, open it as administrator by right clicking on the .exe file. Now select your drive in the drop-down menu and set the persistent storage to anything above 100 MB. Then click create USB or so. Click yes if it asks about also reformatting your drive. It re-formats to change your USB drive so that it can hold bigger files and the EFI information for booting.
6. Now you are ready to choose your target. If you are installing this on a laptop of a different manufacturer (mine is Sager so to change the boot device is to hold F7), go check the manual to see how to change your boot device. Plug the USB into the machine you chose and restart it. Now hold down the boot device manager key. Once you get it select the USB that has CentOS on it.
7. Once you select it, your screen will turn black and bring you to the installer for CentOS. Select everything and whatever. Set your storage to the free space you have ready for it and let it automatically do the partitions. If you know how the partition works, feel free to do it manually.
8. Errors? If you are having trouble finding the Source File or it says there is a missing repository you now need to connect to the internet. You can connect to the internet wirelessly or through ethernet port.
The above image should be kind of identical. Now go to Installation Source, and select from internet and now we go to the centos mirrors site to look for what version you want. For this how to I installed this one: http://mirror.centos.org/centos/7.2.1511/os/x86_64/ . You type that as exactly as you see and click continue or next. This will take a while so go do something for a bit.
9. Once it install and is ready to go, go to software installation and select the applications you want to install. Now when you select the environment for the visuals, select GNOME as it is the easiest one to use. Then begin the installation.
10. While it is installing you should be here:
You should set a root password and a user. This is for security purposes. Also you should learn some basic linux commands (bash, vim, etc).
11. Once it finishes you will now be prompt to login.
12. And that's it. You now have CentOS on your machine. Also you can start fixing other errors (if you have any) using the command prompt under applications.
Oh my goodness... In the last picture of this tutorial you can see an older version of this website. It looks so meh... Anyways, if you have a problem I may be able to help or not, but otherwise go to the CentOS website and post in their forum. Hopefully this guide was simple to follow and not that complicated. Thank you so much~
