Python – web.py + uwsgi + nginx no application found

nginxpythonuwsgiweb.py

i'm trying to deploy nginx uwsgi and web.py

Here is my index.py in /www/python/testme/

import web

urls = (
  '/', 'index'
)

app = web.application(urls, globals())

class index:
        def GET(self):
                return "Hello, world!"

if __name__ == "__main__": app.run()

application = app.wsgifunc

Here is my nginx configuration for python with uwsgi

/etc/nginx/sites-available/python
    server {
            listen          8080;
            server_name     $hostname;
            access_log /www/python/testme/logs/access.log;
            error_log /www/python/testme/logs/error.log;

            location / {
                #uwsgi_pass      127.0.0.1:9001;
                uwsgi_pass      unix:///tmp/test.socket;
                include         uwsgi_params;
                uwsgi_param     UWSGI_SCHEME $scheme;
                uwsgi_param     SERVER_SOFTWARE    nginx/$nginx_version;
            }


    }

Uwsgi ini in /etc/uwsgi/app-available/testme.ini

[uwsgi]
gid = www-data
uid = www-data
logdate = true
logto = /var/log/uwsgi/testme.log
socket = /tmp/test.socket
#socket = 127.0.0.1:3031
master = true
plugins = python

My uwsgi service is working, and nginx is listening port 8080 as expected.

How ever when i access my domain from browser here is error log:
/var/log/uwsgi/testme.log

at the very least, this is wrong -- you have 2 different sockets specified

your uwsgi config:

socket = /tmp/testme.socket

your nginx:

uwsgi_pass      unix:///tmp/test.socket

Node.js + Nginx – What now

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.

Regex – Nginx – Rewrite the request_uri before uwsgi_pass

location /one {
  rewrite /one/(.+) /$1 break;
  include uwsgi_params;
  uwsgi_pass unix:///.../one.sock;
}
