Forwarding port 80 to 8080 using NGINX [closed]

Question

I'm using LEMP stack and Node JS on my debian server. Nginx works on port 80 and Node JS on 8080. I created new subdomain: cdn.domain.com for nodejs app. Currently I can access to Node JS application only like cdn.domain.com:8080/. What I want to do is to configure Nginx so that, when I enter to cdn.domain.com I can get app working on port 80. I think it can be done using nginx upstream. But I can't figure out how.

Answer 1

As simple as like this,

make sure to change example.com to your domain (or IP), and 8080 to your Node.js application port:

server {     listen 80;     server_name example.com;      location / {         proxy_set_header   X-Forwarded-For $remote_addr;         proxy_set_header   Host $http_host;         proxy_pass         "http://127.0.0.1:8080";     } }

NGINX supports WebSockets by allowing a tunnel to be setup between a client and a backend server. In order for NGINX to send the Upgrade request from the client to the backend server, Upgrade and Connection headers must be set explicitly. For example:

# WebSocket proxying map $http_upgrade $connection_upgrade {     default         upgrade;     ''              close; }   server {     listen 80;      # The host name to respond to     server_name cdn.domain.com;      location / {         # Backend nodejs server         proxy_pass          http://127.0.0.1:8080;         proxy_http_version  1.1;         proxy_set_header    Upgrade     $http_upgrade;         proxy_set_header    Connection  $connection_upgrade;     } }
