How to Setup Website Directory (Custom Host) on Centos 7 - linux

Question

I'm trying to figure out how to have the website function after i point the DNS to the server.
by default, (after fresh install of apache, mysql, php) the main server directory is situated at var/www/html so if i upload test html file, via default server ip the html file will show.
i'm trying to setup a custom folder i.e var/www/examplewebsite.com/public_html and then the public_html would function as the go-to folder for when user goes to my website. Multiple websites on one IP (server) would be great too
i found some information from http://bit.ly/1kguprn but i do not see the NameVirtualHost and the paragraph under that.
I'm a newbie to the Centos/Linux environment, any help would be greatly appreciated :)

You have a nice tutorial here: https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-centos-6
Basically, create a folder and an index for testing purposes:
sudo vi /var/www/example.com/public_html/index.html
add the Virtual directive in your apache config file (:
NameVirtualHost *:80
#
# NOTE: NameVirtualHost cannot be used without a port specifier
# (e.g. :80) if mod_ssl is being used, due to the nature of the
# SSL protocol.
#
#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for requests without a known
# server name.
#
<VirtualHost *:80>
ServerAdmin webmaster#example.com
DocumentRoot /var/www/example.com/public_html
ServerName www.example.com
ServerAlias example.com
ErrorLog /var/www/example.com/error.log
CustomLog /var/www/example.com/requests.log
</VirtualHost>
Restart apache:
sudo service httpd restart

Check this documentation for Centos 7. They have a nice initial tutorial.
https://www.digitalocean.com/community/tutorials/an-introduction-to-selinux-on-centos-7-part-2-files-and-processes
First, I will recommend to you that check if you have the httpd service installed and active.
sudo service httpd status
if non active
sudo service httpd start
once active
Check the if the ports 80 and 443 (https are active)
sudo netstat -tulnap | grep :80
sudo netstat -tulnap | grep :443
if they are active, test the server. http://yourserverip or https://yourserverip
By default it should go to the apache webserver page.
Once you can see the page. Try to create the initial index.html page in
/var/www/html
vi /var/www.html/index.html
click i for insert
copy the following html
Test
Test web page
In the tutorial, they will explain the rest of the configuration.
#Moderator The tutorial provide a good long material for the reader, I got punish for answer correctly by the moderator. I think the website are long enough to clarify the question and I think copy again the tutorial here is not proper answer.
Also check the next documentation for changes between Apache 2.2 and 2.4
