If you created your blog without php/ruby (e.g. with jekyll or middleman, you need a webserver to serve the page.
If you host it with nginx, this is a very basic template:
server {
listen *:80;
server_name example.org;
gzip on;
gzip_min_length 1000;
gzip_types text/plain application/xml application/json text/css application/x-javascript;
gzip_disable "MSIE [1-6]\.";
root /home/example/live/_site/;
index index.html;
}
