Several sites development without available domains with Nginx, using IP, in a multisite/vhost environment

Do you need work in web development but project has not registered an IP yet? If you are using Nginx, and your server hosts several websites (vhosts) a way to do it could be this:

Note: this howto runs in a linux / debian7 server, and a fictitious domain "mydomain.net"

•   In /etc/nginx/sites-available/mydomain.net change port to listen, for example:

listen *81;

• reload nginx configuration files:

service nginx reload

Then, you can get this web in this URL: MyServerIP:81 or MyServerDomain:81
