How to run multiple node application with NGINX: same droplet same domain

  • Posted July 21, 2014

I followed the tutorial here with node and NGINX. They work great. But, they all are running the node application from the root of the domain.

I have a number of small node apps and I want to be able to run them like:

http://mydomain/app1 http://mydomain/app2

where app1 may be localhost:9000 and app2 is localhost:9001 etc.

when I change my hosts-enabled file from location / to location /app1/

server {
    listen 0.0.0.0:80;
    server_name 192.241.223.202;
    access_log /var/log/nginx/ddApp.log;

    location /app1/ {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header HOST $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://127.0.0.1:9000;
        proxy_redirect off;
    }
}

my application is launched (node sends down the html document) but the browser can’t follow any of the links (load any resources …404’s).

This direct link can get the resouces:

http://192.241.223.202:9000/app/b7672478.app.js

but through the app1 path

http://192.241.223.202/app1/app/b7672478.app.js

NGINX just serves up the root html document.

Actually all requests to the app1 path produce the same response.

The NGINX docs just make my head hurt (as well as my pride).

Any help and direction would be great.

Oh happy days! We are up with app1! … other than a couple of bootstrap fronts out of the bower component failing to pick up the app1 base … I’ll deal with it later. Also the <base> tag needs a trailing slash so for this baby it was:

<base href="/app1/">

THANK YOU SO MUCH!!!

I spent hours and hours trying to solve this same problem. Knowing those hours are wasted because I needed a trailing slash is heartbreaking, but so glad I found this post.

        rewrite ^/app1/(.*)$ /$1 break;
    }
}

nginx -s reload

http://192.241.223.202/app1/ in a new browser window is still broken.

Try adding

rewrite ^/app1/(.*)$ /$1 break;

under

location /app1/ {

and restarting nginx. Does that work?
