nginx HTTPS serving with same config as HTTP

Question

Is there a way to share configuration directives across two nginx server {} blocks? I'd like to avoid duplicating the rules, as my site's HTTPS and HTTP content are served with the exact same config.

Currently, it's like this:

server {
  listen 80;
  ...
}

server {
  listen 443;

  ssl on; # etc.
  ...
}

Can I do something along the lines of:

server {
  listen 80, 443;
  ...

  if(port == 443) {
    ssl on; #etc
  }
}

Answer 1

Per Igor,

You can combine this into one server block like so:

server {
    listen 80;
    listen 443 default_server ssl;

    # other directives
}

I don't know of a way like you suggest, but there's certainly an easy and maintainable way:

server {
    listen 80;
    include serverFoo.conf;
}
server {
    listen 443;
    ssl on;
    include serverFoo.conf;
}

Just to add to Igor/Jauder's post, if you're listening to a specific IP you can use:

listen xxx.xxx.xxx.xxx;
listen xxx.xxx.xxx.xxx:443 default ssl;
