For hosting we are going to user Name Based Virtual Hosting (NBVH).
NBVH is commonly used for host multiple websites on same IP address or same server.
To host two or more websites on a single server follow below steps :
Step 1 : Create a website directory
Create a directory for website :
Use below command for create new directory.
mkdir /var/www/website-example.comStep 2 : Put files in directory
Now put your code in this directory or create an index.html page with following command.
nano /var/www/website-example.com/index.htmlStep 3 : Change directory permission
Next, change the ownership of website-example.com directory to www-data:
chown -R www-data:www-data /var/www/website-example.comStep 4 : Create a virtual host configuration file
Now, you will need to create an apache virtual host configuration file to run two or more websites.
Create a virtual host config file for website-example.com.
Below command will create new file & open for editing.
nano /etc/apache2/sites-available/website-example.com.confAdd the following lines in opened file, Save and close after editing.
<VirtualHost *:80>
	ServerAdmin webmaster@localhost
	DocumentRoot /var/www/website-example.com/
	ErrorLog ${APACHE_LOG_DIR}/error.log
	CustomLog ${APACHE_LOG_DIR}/access.log combined
	<Directory /var/www/website-example.com/>
		AllowOverride All
	</Directory>
	ServerName website-example.com
	RewriteEngine on
	RewriteCond %{SERVER_NAME} =www.website-example.com [OR]
	RewriteCond %{SERVER_NAME} =website-example.com
	RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>Step 5 : Enable new site config
Enable the new created virtual host configuration file with the following commands :
a2ensite website-example.comStep 6 : Restart apache server
Restart apache for new changes.
systemctl restart apache2Step 7 : Run new website
Now, open your preferred browser and run URL http://website-example.com.
That's all done here.
