如何在Ngnix上为生产环境配置Node.js

Question

I have to develop a chat system using angularjs and nodejs. To send and receive message i use socket.io. For node js i create nodejs server using localhost cmd.

this is working fine but now i have to put this to live.

So i do not understand how to put nodejs code on live

i have vps server where node js is working

This is my angularjs system url

https://app.twodegrees.io/#/

this is nodejs server link where socket is working

https://app.twodegrees.io:8080/socket.io/socket.io.js

So my question is : How i use nodejs code for production enviroment on ngnix server thanks

Answer 1

One way of doing this is to configure nginx as a reverse proxy. This will redirect requests arriving at your server to the nodeJs application running on that server.

Here is an example block that you could add to your /etc/nginx/sites-available/default file, this block will redirect requests from app.twodegrees.io to port 3000 on the local machine.

server {
    listen 80;

    server_name app.twodegrees.io;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Answer 2

Could you provide your directory structure? I think it depends on if you want do serve your frontend via nginx or nodejs ...

As I understand the example configuration above only works in your case if nodejs is serving the frontend.

1. create a new directory in your node.js backend application called public and put in your whole frontend application
2. add app.use(express.static(__dirname + '/public')); before you call listen in your server.js

UPDATE:

Configuration for angular frontend

server {
    listen 80;
    server_name app.twodegrees.io;
    root /usr/share/html;
    index index.html;

    location / {
        try_files $uri $uri/ /index.html;
    }
}

Configuration for Socket.io backend

server {
    listen 80;

    server_name socket.twodegrees.io;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}
