## Create configuration file for each host
$ sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/domain.test.conf

$ sudo vi /etc/apache2/sites-available/domain.test.conf

<VirtualHost *:80>
 # The ServerName directive sets the request scheme, hostname and port that
 # the server uses to identify itself. This is used when creating
 # redirection URLs. In the context of virtual hosts, the ServerName
 # specifies what hostname must appear in the request's Host: header to
 # match this virtual host. For the default virtual host (this file) this
 # value is not decisive as it is used as a last resort host regardless.
 # However, you must set it for any further virtual host explicitly.
 #ServerName www.example.com

   ServerAdmin webmaster@domain.test
   ServerName domain.test
   ServerAlias www.domain.test
   DocumentRoot /var/www/html/domain.test/public_html

# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
 # error, crit, alert, emerg.
 # It is also possible to configure the loglevel for particular
 # modules, e.g.
 #LogLevel info ssl:warn

ErrorLog ${APACHE_LOG_DIR}/error.log
 CustomLog ${APACHE_LOG_DIR}/access.log combined

# For most configuration files from conf-available/, which are
 # enabled or disabled at a global level, it is possible to
 # include a line for only one particular virtual host. For example the
 # following line enables the CGI configuration for this host only
 # after it has been globally disabled with "a2disconf".
 #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

## Create demo web pages for each host
Let us create a sample page for domain.test site. To do so, run:

$ sudo vi /var/www/html/domain.test/public_html/index.html

<html>
 <head>
 <title>www.ostechnix.lan</title>
 </head>
 <body>
 <h1>Hello, This is a test page for ostechnix1.lan website</h1>
 </body>
</html>

## Create web directory for each host
$ sudo mkdir -p /var/www/html/domain.test/public_html

The above directorie is owned by root user. We need to change the ownership to the regular user.

$ sudo chown -R $USER:$USER /var/www/html/domain.test/public_html

Next, set read permissions to the Apache root directory i.e /var/www/html/ using command:

$ sudo chmod -R 755 /var/www/html/

## Enable virtual host configuration files
After making the necessary changes, disable the default virtual host config file i.e 000.default.conf, and enable all newly created virtual host config files as shown below.

$ sudo a2dissite 000-default.conf

$ sudo a2ensite domain.test.conf

Restart apache web server to take effect the changes.

$ sudo systemctl restart apache2

## Install Apache webserver
$ sudo apt-get install apache2

## Test Virtual hosts
Open /etc/hosts file in any editor:

$ sudo vi /etc/hosts

Add all your virtual websites/domains one by one like below.
