Forwarding port 80 to 8080 using NGINX [closed]

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 proxyingmap $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;    }}

Simple is:

server {    listen   80;    server_name  p3000;    location / {        proxy_pass http://0.0.0.0:3000;        include /etc/nginx/proxy_params;    }}
