CentOS - How to install

-
In this post I will describe how to install CentOS 7.

Nowadays install linux is not so difficult, as you will see in this post.

First step, download ISO file from internet:
http://isoredirect.centos.org/centos/7/isos/x86_64/CentOS-7-x86_64-DVD-1804.iso

Now, you can mount your ISO file in your virtualization server or put in your computer drive and wait the wizard starts.

 In the first screen choose your language and click on "Continue".



Now click on "DATE & TIME".


Choose your place, I live in the south of Brazil, then I selected Americas Sao Paulo. 
After click "Done".


Choose your "KEYBOARD".


In my case, Portuguese (Brazil).
Click "Done".


In this step click on "INSTALLATION DESTINATION".

 

Here you can choose yours partitions size, in this case I left in the default configuration.
Click "Done" again.


Now click on "NETWORK & HOST NAME".


I like to configure the network interface here, but you can do this after the instalation.
To configure just enable the interface and click in "Configure".
Do not forget do change the "Host name" and "Apply".

"Done" again.


Click on"Begin Installation".


 Set your root password.


 Just wait until this screen and click in "Reboot".



After the installation always update your system, do not forget it.

To do this login in your CentOS and type:
yum update

Wait the download, installation and verification steps
