NGINX rewrite to new protocol and port

Question

I am trying to rewrite requests to http://www.example.com:88 to https://www.example.com:4430

At the moment, I am stuck with nonstandard ports. Here is my configuration:

upstream pool {
  server 127.0.0.1:5001;
  server 127.0.0.1:5002;
}

server {
  listen 88;
  listen 4430 default ssl;

  if ($ssl_protocol = "") {
    rewrite ^ https://$server_name:4430/$uri permanent;

    # this also fails with https://www.example.com/:4430
    #rewrite ^/(.*)$ https://$host:4430/$1 permanent;
    #rewrite ^ https://www.example.com:4430/ permanent;
  }

  location / {
    proxy_pass http://pool;
    proxy_set_header Host $host;
    proxy_redirect off;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}

This results in http://www.example.com:88/path being rewritten to https://www.example.com/path:4430

What's the syntax to get the port after the domain name?

Answer 1

I suggest use separate server for http redirection and another one for ssl:

server {
  listen 88;
  return 302 https://$host:4430$request_uri;
}
server {
  listen 4430 ssl default_server;
  ...
