nginx reverse proxy server multiple websites file arrangements - nginx

Question

I follow this article. I wonder what should be the file structure of "/etc/nginx/sites-available" if I want to host multiple websites and what should be the content of each files under "sites-available" folder (Look at the sample "default" file content down below for a single website configuration)?
I am running node.js, express.js and EJS for 2 websites.
I created 2 different instances of the same website like this:
/home/debian/public
/home/debian/public2
Under both of these folders, each of them has their own individual "server.js" file and the content of them are like this:
server.js
// Load Node modules
var express = require('express');
const ejs = require('ejs');
// Initialize Express
var app = express();
// Render static files
app.use(express.static('/home/debian/public'));
// Set the view engine to ejs
app.set('view engine', 'ejs');
// Port website will run on
app.listen(8080);
// *** GET Routes - Display Pages ***
// Root Route
app.get('/', function(req, res){
var listnames = ["1", "2", "3];
// Render index page
res.render('/home/debian/public/views/pages/index.ejs', {
// EJS variable and server side variable
listnames: listnames
});
});
I configured one public folder's port to 8080 and public2 to 9000
According to this article if you have only a single server, the file "default" under "/etc/nginx/sites-available" should be configured like this:
default
server {
root /var/www/html;
index index.html index.htm index.nginx-debian.html;
server_name auroraspotter.space;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://localhost:8080;
proxy_set_header Host $http_host;
proxy_cache_bypass $http_upgrade;
proxy_redirect off;
}
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/auroraspotter.space/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/auroraspotter.space/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = auroraspotter.space) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80 default_server;
listen [::]:80 default_server;
server_name auroraspotter.space;
return 404; # managed by Certbot
However, I wonder what should be the file structure of "/etc/nginx/sites-available" if I want to host multiple websites and what should be the content of each files?
Thanks.

You can have only 1 file named default.conf but you need to edit it as follows:
server {
root /var/www/html;
index index.html index.htm index.nginx-debian.html;
server_name auroraspotter.space;
location /path1 {
proxy_pass http://localhost:8080;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_set_header Host $http_host;
proxy_cache_bypass $http_upgrade;
proxy_redirect off;
}
location /path2 {
proxy_pass http://localhost:9000;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_set_header Host $http_host;
proxy_cache_bypass $http_upgrade;
proxy_redirect off;
}
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/auroraspotter.space/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/auroraspotter.space/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = auroraspotter.space) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80 default_server;
listen [::]:80 default_server;
server_name auroraspotter.space;
return 404; # managed by Certbot
Now when you will send request to auroraspotter.space/path1, it will be served by nodejs running on port 8080 and when you will send request to auroraspotter.space/path2, it will be served by nodejs running on port 9000.
