Install CentOS 8 Netboot

Instead of downloading the very heavy full version of CentOS DVD ISO, we could opt for the lighter version CentOS BOOT ISO which is around 600mb against the 7.7 GB of the full version. This also will allow you to choose and customize the list of packages you want to install, avoiding applications that you will never use.

If you want to understand how to do it, all you have to do is follow the steps below.
I performed the installation on a Virtual Machine.

Download

First download the ISO, you can find it on the official website at this address

Choose the geographical area closest to you. Make sure to download the CentOS Boot version of approximately 600mb

Start CentOS 8 install

As soon as the ISO is downloaded, if you use a Virtual Machine select the ISO and boot it from there, otherwise you should have the ISO bootable by an external Hard Drive.

Initial configurations

As you can see, a first screen is made up of various sections to be configured, note that those with the yellow triangle exclamation, or warning marks, are mandatory in order to continue. 

The first configuration is Installation Source, here is where you need to enter a CentOs mirror URL to configure it. There are several mirrors for Centos 32 and 64 bit. You can also find them on their official website.

For example the most used for 64bit is

The next step is to select the packages and services to be installed, and it is right here where we have the possibility to install a system tailor-made.

Personally, I often opt for Server with GUI.

Now we have to configure the destination (Hard Drive). Select your dedicated partition, check well that everything is in order and continue.

Check back quickly to see if everything is well configured, then start the installation. The final step will be to enter your username and password, press on finish configuration.

Now everything is ready, enjoy!
