ServerAdmin webmaster@vhost.com
DocumentRoot /var/www/vhost
ServerName vhost.com
ErrorLog logs/vhost.com-error_log
CustomLog logs/vhost.com-access_log common


5] Above virtual host section we have defined html web page path as /var/www/vhost, so this directory has to exist along with the index.html page for apache to serve http request received on 8080.
