Forwarding port 80 to 8080 using NGINX

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

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;
    }
}

you can do this very easy by using following in sudo vi  etc nginx sites-available default  server       listen 80 default server      listen      80 default server       server name   your domain       location  health               access log off              return 200  healthy n              location                 proxy pass http   localhost 8080               proxy http version 1 1              proxy set header Upgrade  http upgrade              proxy set header Connection  upgrade               proxy set header Host  host              proxy set header X-Forwarded-For  proxy add x forwarded for              proxy cache bypass  http upgrade

This is how you can achieve this   upstream       nodeapp 127 0 0 1 8080     server       listen 80         The host name to respond to     server name cdn domain com       location                 proxy pass http   nodeapp  1 is args args          proxy set header X-Real-IP   remote addr          proxy set header X-Forwarded-For  remote addr          proxy set header Host  host          proxy set header X-Real-Port  server port          proxy set header X-Real-Scheme  scheme            You can also use this configuration to load balance amongst multiple Node processes like so   upstream       nodeapp 127 0 0 1 8081      nodeapp 127 0 0 1 8082      nodeapp 127 0 0 1 8083      Where you are running your node server on ports 8081  8082 and 8083 in separate processes  Nginx will easily load balance your traffic amongst these server processes

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             Source  https   eladnava com binding-nodejs-port-80-using-nginx

You can define an upstream and use it in proxy pass  http   rohanambasta blogspot com 2016 02 redirect-nginx-request-to-upstream html  server        listen        8082      location                    proxy pass  test server           proxy set header Host  host           proxy set header X-Real-IP  remote addr           proxy set header X-Forwarded-For  proxy add x forwarded for           proxy set header X-Forwarded-Proto  scheme           proxy redirect    off                    upstream test server                     server test-server 8989

This worked for me   server     listen  80     server name example com www example com     location          proxy pass                          http   127 0 0 1 8080       proxy set header Host                host      proxy set header X-Real-IP           remote addr        proxy set header X-Forwarded-For     proxy add x forwarded for          If it does not work for you look at the logs at sudo tail -f  var log nginx error log
