self signed ssl certificates

When setting up a development server that will be accessible over the internet, it is a good idea to use ssl.

Below are some snippets for setting up self signed certificates:

sudo openssl req -x509 -nodes -days 365 \
                 -newkey rsa:2048 \
 -keyout /etc/nginx/ssl/nginx.key \
