在nginx中将81重定向到443

Question

I'm trying to get all traffic served as https. However the server is behind a AWS ELB. So I've setup a listener on the ELB to direct 80 -> 81 and 443 -> 80 ie all http traffic goes to port 81 on the rails server. And all https traffic goes to port 80 (ssl terminated on the ELB) I'm trying to get nginx to redirect all port 81 traffic to https. Seems simple enough.

So I have a server block called redirect_to_ssl in the sites_available directory it looks like this:

server {
      listen         81;
      server_name    redirect_to_ssl;
      return         301 https://$hostname$request_uri;
}

I've symlinked this file into sites-enabled

And I've reloaded the config for nginx

But when I try and curl localhost:81 I get connection refused. And when I try and browse the site from outside the ELB, it does nothing

Any ideas? Is there another way of doing what I'm trying to do with AWS ELB's ?

Answer 1

Directive server_name is not a label, it's the name of the virtual server, ie its value must match with HTTP Host header of ingoing requests for the server block to be accessed. So it will likely never match any Host actual host header in use with your setup and never be reached.

Read the documentation .

The use of $hostname is also weird if you use a load balancer ...
