Serving multiple node apps with nginx on same domain

Question

I would like to host 2 different node applications with nginx from the same domain and am having some trouble. I would like to have:

mydomain.com point to node app firstApp and otherapp.mydomain.com point to node app otherapp

Right now, I can access firstApp just fine, but I cannot access otherapp via otherapp.mydomain.com.

My config for firstApp looks like this:

upstream firstApp{
 server 127.0.0.1:8123;
}
server{
 server_name mydomain.com;
 access_log /var/log/nginx/me.log;
 location / {
 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_set_header X-NginX-Proxy true;
 proxy_pass http://firstApp/;
 proxy_redirect off;
 }
}

My config for otherapp looks like this:

upstream otherapp{
 server 127.0.0.1:8124;
}
server{
 server_name otherapp.mydomain.com;
 access_log /var/log/nginx/me.log;
 location / {
 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_set_header X-NginX-Proxy true;
 proxy_pass http://otherapp/;
 proxy_redirect off;
 }
}

I have created both configurations in the nginx sites-available directory, they are both linked in the sites-enabled directory, and I have restarted nginx. Can someone tell me what I'm doing wrong?

Thanks, Swaraj

Answer 1

Just found out what the problem was. Though my nginx configs were correct, I had not added my desired subdomain to my domain name provider (namecheap). I added my subdomain on namecheap, and everything is working correctly now.

you should config your nginx file like this

server {
 listen 80; 
 server_name biger.yourdomain.cn;
 access_log /data/log/nginx/access_ab.log;
 error_log /data/log/nginx/error_ab.log;
 location /firstApp {
 proxy_store off;
 proxy_redirect off;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header X-Real-IP $remote_addr;
 proxy_set_header Host $http_host;
 proxy_pass http://localhost:8001/;
 }
}

maeby you need add this code to your project

app.enable('trust proxy');

I was facing the same problem, after spending time on research I wrote a blogpost where I explained with details how I solved it, I hope it helps. Here it is: http://blog.donaldderek.com/2013/08/cf-i-configure-your-staging-machine-with-node-js-and-nginx/
