i install it in this way:::
1.Copy it in global path (like /usr/local/bin) in vhost file(new)
2.then give vhost file permission (sudo chmod +x /usr/local/bin/vhost) and restart apache
3.then go to your project web directory then sudo vhost -s your site name
complete.... even you don't need to restart apache
