vjk2005's questions

I’m hosting a Node.js Wiki server (openKB) on /wiki behind an Nginx server. How can I proxy_pass from Nginx while also having Nginx serve static assets hosted at /wiki/public and /wiki/images and /wiki/stylesheets/build and so on.

What I had tried but did not work:

location /wiki {
        proxy_pass http://127.0.0.1:4444;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
}

EDIT:

Site: dffrnt.com/wiki

Output: While the app runs just fine, the static assets are not getting served at all. I noticed some of the assets are 404 while some others are 503.

Here’s what’s on the server...

I got nginx + uWSGI running on localhost inside a virtualenv with a simple hello world program, but I get this error when I replace the hello world with a simple Flask app:

File "./wsgi_configuration_module.py", line 1, in <module>
    from flask import Flask
ImportError: No module named flask
unable to load app mountpoint

Here's the flask app (wsgi_configuration_module.py):

from flask import Flask
application = Flask(__name__)

@application.route("/")
def hello():
    return "hello world"

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

uWSGI config (app_conf.xml):

<uwsgi>
    <socket>127.0.0.1:9001</socket>
    <chdir>/srv/www/labs/application</chdir>
    <pythonpath>/srv/www</pythonpath>
    <module>wsgi_configuration_module</module>
    <callable>application</callable>
    <no-site>true</no-site>
</uwsgi>

nginx config:

server {
    listen   80;
    server_name localhost;
    access_log /srv/www/labs/logs/access.log;
    error_log /srv/www/labs/logs/error.log;

    location / {
        include        uwsgi_params;
        uwsgi_pass     127.0.0.1:9001;
    }

    location /static {
        root   /srv/www/labs/public_html/static/;
        index  index.html index.htm;
    }
}

virtualenv stored in ~/virtual_env with Python 2.7 + nginx + uWSGI + Flask installed in a virtualenv called basic.

Things I've tried to solve this:

1. set the --home (-H) option to my virtualenv folder ~/virtual_env while running uWSGI.

Other info:

1. I have the same setup working outside of a virtualenv. Things go wrong only when I try to replicate the setup inside of a virtualenv.

Where have I gone wrong?

After a long time on shared hosting, I'm moving my stuff to a VPS and it has become necessary to learn about Nginx + uWSGI to deploy my apps (python). After spending a couple of weeks learning the basics, I'm in the process of setting up my local machine (ubuntu 11.04) to run my apps on Nginx + uWSGI. I'm using the "Hello world" Ubuntu 10.10 linode guide.

The setup was simple but when I run http://localhost/ or http://127.0.0.1 I get a 502 Bad Gateway everytime. Appreciate pointers on how to get the setup working.

My nginx.conf: [ I backed up the default nginx conf (which works fine and shows "Welcome to Nginx" when I hit http://localhost/) and replaced it with this custom nginx conf from the linode guide that links nginx to the uWSGI server. ]

    worker_processes  1; 
    events { worker_connections  1024; } 
    http { 
        server { 
            listen 80;
            server_name localhost; 
            access_log /srv/www/myHostname/logs/access.log; 
            error_log /srv/www/myHostname/logs/error.log; 

            location / { 
                include  uwsgi_params; 
                uwsgi_pass    127.0.0.1:9001;
            } 

            location /static { 
                root   /srv/www/myHostname/public_html/static/;
                index  index.html index.htm;
            }
        }
    }

My uWSGI conf is exactly the same as detailed in the linode guide I linked above, with the one change that "duckington.org" in their example replaced with "myHostname" in my setup. No errors in my nginx error log. Nginx installed at /opt/nginx and uWSGI is at /opt/uwsgi as laid out in the guide linked above. I haven't touched any files the guide doesn't talk about.

What I have tried to solve this, so far:

1. Starting, stopping and restarting nginx and uWSGI services after modifying their configs.
2. Tried the 'debian layout' with sites-enabled etc to add my custom vhost listed above while leaving the default nginx.conf untouched (except for the include statement to point to the vhost in sites-enabled). Nginx did not even start and the error log reported a "conflicting server name "localhost" on 0.0.0.0:80, ignored" error.
3. Read a bunch more guides on Nginx + uWSGI setups without getting any further in solving the issue.
