Installing CentOS 7 – A Graphical Tour for Linux Beginners

If you are new on the Linux platform, I am sure you feel overwhelmed with all the different versions available. Choosing one is not an easy task, and each version has its own pros and cons.

Let me tell you why I like CentOS:

  • It is very stable
  • It has well tested features
  • There is a big community around it
  • It has many large software repositories
  • It is Part of the RedHat / Fedora family

Installing CentOS

Installing a new operating system may seem challenging, but CentOS has always made this task a simple one.

The first thing to do is to download it from the CentOS website.

Once downloaded, burn the DVD images onto a couple blank disks. Insert disk number 1 on your computer and use it to boot it.

 

The first screen will present some options. Select Install CentOS 7 using your keyboard’s up and down arrows and press the Enter key:

CentOS-7

The next screen will show you options to configure your keyboard.  Choose the appropriate option and click Continue.

The following screen is an important one. It shows different icons that allows you to configure your new operating system. We’ll click on some of them.

Click on Date & Time:

Select your time zone and click Done at the top left corner when ready.

CentOS-7-004

Now click on Software Selection:

Click Done at the top left corner when ready.

Finally click on Installation Destination option. I recommend you to leave everything the way it is in here.

Click Done at the top left corner when ready.

Next step is Kdump. Kdump is a kernel crash dumping mechanism. It helps developers know what went wrong in case your computer crashes. I usually disable it, but you can keep it enabled if you want to help developers find new problems with the system.
