create a virtual host in apache source install code example

Example: create a virtual host in apache

STEP 1:
# domain: DOMAIN_URL
# public: /var/www/DOMAIN_URL/public_html/public/

<VirtualHost *:80>
	# Admin email, Server Name (domain name), and any aliases
	ServerAdmin admin@DOMAIN_URL
	ServerName  DOMAIN_URL
	ServerAlias DOMAIN_URL
	
	# Index file and Document Root (where the public files are located)
	DirectoryIndex index.html index.php
	DocumentRoot /var/www/DOMAIN_URL/public_html/public/
	<Directory /var/www/DOMAIN_URL/public_html/public/>
        Options Indexes FollowSymLinks
        DirectoryIndex index.php
        AllowOverride All
        Require all granted
        Order allow,deny
        allow from all
	</Directory>
	# Log file locations
	LogLevel warn
	ErrorLog  /var/www/DOMAIN_URL/log/error.log
	CustomLog /var/www/DOMAIN_URL/log/access.log combined
</VirtualHost>


STEP 2: With our virtual host files created, we must enable them. We’ll be 
using the a2ensite tool to achieve this goal.

sudo a2ensite example.com.conf

STEP 3: When you are finished, you need to restart Apache to make these changes
take effect and use systemctl status to verify the success of the restart.

sudo systemctl restart apache2
