Question

How to serve two node.js apps on one domain? Site #2 accessible through localhost but not through url. (Nginx)

I am attempting to run two node.js applications from the same droplet, off the same url. I am serving the first app from http://finleywill.com, and would like to serve the second app from http://finleywill.com/todo.

I am running nginx on the server.

The first app, my portfolio page, listens to port 5000.

The second app, a to-do list, listens to port 8888.

  • When I go to 67.205.148.223:8888, the app loads.
  • However, trying to connect via http://finleywill.com/todo produces a “504 Gateway Time-out”

/etc/nginx/sites-available/finleywill.com is as following:

server { listen 80; listen [::]:80;

    root /var/www/finleywill.com/html;
    index index.html index.htm index.nginx-debian.html;

    server_name finleywill.com www.finleywill.com;

    access_log /root/source/access.log;
    error_log /root/source/error.log;

    location / {
            proxy_pass http://localhost:5000;
            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;
    }

    location /todo {
            proxy_pass http://localhost:8888;
            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;
    }

}

I use PM2 to run the apps as system processes

App name │ id │ version │ mode │ pid │ status │ restart │ uptime │ cpu │ mem │ user │ watching │


app │ 0 │ 1.0.0 │ fork │ 27064 │ online │ 0 │ 72m │ 0% │ 55.5 MB │ root │ disabled │ app-todo │ 1 │ 1.0.0 │ fork │ 27156 │ online │ 0 │ 40m │ 0% │ 37.0 MB │ root │ disabled │

I figured it out with help from a friend!

…as per https://serverfault.com/questions/650117/serving-multiple-proxy-endpoints-under-location-in-nginx

I changed /etc/nginx/sites-available/finleywill.com to the following:

server { listen 80; listen [::]:80;

    root /var/www/finleywill.com/html;
    index index.html index.htm index.nginx-debian.html;

    server_name finleywill.com www.finleywill.com;

    access_log /root/source/access.log;
    error_log /root/source/error.log;

    location / {
            proxy_pass http://localhost:5000;
            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;
    }
   
   (LINE BELOW HAS CHANGED)
   location ^~ /todo/ {
            proxy_pass http://localhost:8888/;
    }

}

I have configured as same as above, but the page loading

server {
    listen 443 ssl http2;
    listen [::]:443 ssl;
    include snippets/ssl-cert.conf;
    include snippets/ssl-params.conf;

    server_name dev.pm-lucida.com www.dev.pm-lucida.com;
	
    error_log   /var/log/nginx/complus.error.log;
    access_log  /var/log/nginx/complus.access.log;
 #   client_max_body_size 4M;


  location / {
    rewrite ^/(.*) /$1 break;
    proxy_ignore_client_abort on;
    proxy_pass http://13.234.214.144:3000;
    proxy_set_header  X-Real-IP  $remote_addr;
    proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header  Host $http_host;
    proxy_redirect off;
    proxy_http_version 1.1;
    proxy_set_header  Upgrade $http_upgrade;
    proxy_set_header  Connection "upgrade";
    client_max_body_size 4M;
  }
   location ^~/Charac/ {

        proxy_pass http://13.234.214.144:3001/;
}


}

server {
    listen 80;
    listen [::]:80;

    server_name dev.pm-lucida.com;

    return 302 https://$server_name$request_uri;
}
