How to configure nginx so it works with Express?
- by Michal Stefanow
I'm trying to configure nginx so it proxy_pass requests to my node apps. Question on StackOverflow got many upvotes: http://stackoverflow.com/questions/5009324/node-js-nginx-and-now and I'm using config from there.
(but since question is about server configuration it is supposed to be on ServerFault)
Here is the nginx configuration:
server {
listen 80;
listen [::]:80;
root /var/www/services.stefanow.net/public_html;
index index.html index.htm;
server_name services.stefanow.net;
location / {
try_files $uri $uri/ =404;
}
location /test-express {
proxy_pass http://127.0.0.1:3002;
}
location /test-http {
proxy_pass http://127.0.0.1:3003;
}
}
Using plain node:
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(3003, '127.0.0.1');
console.log('Server running at http://127.0.0.1:3003/');
It works!
Check: http://services.stefanow.net/test-http
Using express:
var express = require('express');
var app = express(); //
app.get('/', function(req, res) {
res.redirect('/index.html');
});
app.get('/index.html', function(req, res) {
res.send("blah blah index.html");
});
app.listen(3002, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3002/');
It doesn't work :(
See: http://services.stefanow.net/test-express
I know that something is going on.
a) test-express is NOT running
b) text-express is running
(and I can confirm it is running via command line while ssh on the server)
root@stefanow:~# service nginx restart
* Restarting nginx nginx [ OK ]
root@stefanow:~# curl localhost:3002
Moved Temporarily. Redirecting to /index.html
root@stefanow:~# curl localhost:3002/index.html
blah blah index.html
I tried setting headers as described here: http://www.nginxtips.com/how-to-setup-nginx-as-proxy-for-nodejs/ (still doesn't work)
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;
I also tried replacing '127.0.0.1' with 'localhost' and vice versa
Please advise. I'm pretty sure I miss some obvious detail and I would like to learn more. Thank you.
