Copying the default virtual host .conf file example1.com virtual host

root@linuxhelp:/# cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/example1.com.conf

Copying the default virtual host .conf file example2.com virtual host

root@linuxhelp:/# cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/example2.com.conf

Configure the virtual host for example1.com

root@linuxhelp:/# vi /etc/apache2/sites-available/example1.com.conf 

Configure the virtual host for example2.com

root@linuxhelp:/# vi /etc/apache2/sites-available/example2.com.conf 

Making document Root directory as example1

root@linuxhelp:/# mkdir /var/www/html/example1

Making document Root directory as example2

root@linuxhelp:/# mkdir /var/www/html/example2

Making the index.html file for example1.com

root@linuxhelp:/# vi /var/www/html/example1/index.html

Making the index.html file for example1.com

root@linuxhelp:/# vi /var/www/html/example2/index.html

Enabling virtual host site example1.com.

root@linuxhelp:/# a2ensite example1.com.conf
Enabling site example1.com.
To activate the new configuration, you need to run:
  systemctl reload apache2

Enabling virtual host site example2.com.

root@linuxhelp:/# a2ensite example2.com.conf
Enabling site example2.com.
To activate the new configuration, you need to run:
  systemctl reload apache2

Restart the apache server

root@linuxhelp:/# systemctl restart apache2

Put host entries for virtual hosts

root@linuxhelp:/# vi /etc/hosts

Ping the www.example1.com

Ping the www.example1.com

With this the implement of multiple virtual hosts comes to an end.
