Nginx works as a front end server, which in this case proxies the requests to a node.js server. Therefore you need to setup an nginx config file for node.
This is what I have done in my Ubuntu box:
Create the file yourdomain.com
at /etc/nginx/sites-available/
:
vim /etc/nginx/sites-available/yourdomain.com
In it you should have something like:
# the IP(s) on which your node server is running. I chose port 3000.
upstream app_yourdomain {
server 127.0.0.1:3000;
keepalive 8;
}
# the nginx server instance
server {
listen 80;
listen [::]:80;
server_name yourdomain.com www.yourdomain.com;
access_log /var/log/nginx/yourdomain.com.log;
# pass the request to the node.js server with the correct headers
# and much more can be added, see nginx config options
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://app_yourdomain/;
proxy_redirect off;
}
}
If you want nginx (>= 1.3.13) to handle websocket requests as well, add the following lines in the location /
section:
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
Once you have this setup you must enable the site defined in the config file above:
cd /etc/nginx/sites-enabled/
ln -s /etc/nginx/sites-available/yourdomain.com yourdomain.com
Create your node server app at /var/www/yourdomain/app.js
and run it at localhost:3000
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(3000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3000/');
Test for syntax mistakes:
nginx -t
Restart nginx:
sudo /etc/init.d/nginx restart
Lastly start the node server:
cd /var/www/yourdomain/ && node app.js
Now you should see "Hello World" at yourdomain.com
One last note with regards to starting the node server: you should use some kind of monitoring system for the node daemon. There is an awesome tutorial on node with upstart and monit.
Change listen option to this in your catch-all server block. (Add default_server
) this will take all your non-defined connections (on the specified port).
listen 80 default_server;
if you want to push everything to index.php if the file or folder does not exist;
try_files $uri /$uri /index.php;
Per the docs, It can also be set explicitly which server should be default, with the **default_server** parameter in the listen directive
Best Answer
You could use the
$scheme
variable:From the docs:
Which would then use the same protocol as the original request.
