deploying web.py with nginx, uwsgi service and linux

It is possible to deploy web.py with nginx using a uWSGI 2.0.11 or later. Note that earlier versions available in the repository (such as 1.9.17) may not work! uWSGI is available via python’s pip installer. Nginx natively supports uWSGI since 0.8.40. The following is for python 2.7.

sudo apt-get install python-pip nginx python-webpy python-dev libpcre3-dev
sudo apt-get remove uwsgi uwsgi-core
sudo pip install uwsgi

Create the folders and set ownership:

sudo mkdir -p /var/srv/www/mon/logs
sudo mkdir -p /var/srv/www/mon/public_html/static
sudo mkdir -p /var/srv/www/mon/app
sudo chown www-data:www-data -R /var/srv/www/mon

Add a file: /etc/nginx/sites-available/mon

server {
	    listen          80;
	    server_name     $hostname;
	    access_log /var/srv/www/mon/logs/access.log;
	    error_log /var/srv/www/mon/logs/error.log;

	    location / {
	        uwsgi_pass      unix:///run/uwsgi/app/mon/mon.socket;
	        include         uwsgi_params;
	        uwsgi_param     UWSGI_SCHEME $scheme;
	        uwsgi_param     SERVER_SOFTWARE    nginx/$nginx_version;


	    location /static {
	        root   /var/srv/www/mon/public_html/;
	        index  index.html index.htm;


Enable the site and disable the default nginx website:

sudo ln -s /etc/nginx/sites-available/mon /etc/nginx/sites-enabled/mon
sudo rm /etc/nginx/sites-enabled/default

Create file: /var/srv/www/mon/app/mon.xml


Create file: /var/srv/www/mon/app/mon.py

import os
import sys


os.environ['PYTHON_EGG_CACHE'] = '/var/srv/www/mon/.python-egg'

def application(environ, start_response):
	status = '200 OK'
	output = 'Hello World!'

	response_headers = [('Content-type', 'text/plain'),
	                ('Content-Length', str(len(output)))]
	start_response(status, response_headers)

	return [output]

If upstart, as used in Linux Mint 17.2, is available, create file: /etc/init/mon.conf

description "mon uwsgi"
author "TSC"

start on runlevel [2345]
stop on runlevel [016]

env DIR=/run/uwsgi/app/mon
env USER=www-data
env GROUP=www-data
env PERMS=0755

pre-start script
  mkdir -p $DIR              || true
  chmod $PERMS $DIR       || true
  chown $USER:$GROUP $DIR || true
end script

exec uwsgi /var/srv/www/mon/app/mon.xml

Restart nginx and start the new mon service. These commands on many linux systems:

sudo service nginx stop
sudo service mon start
sudo service nginx start
