### BEGIN INIT INFO
# Provides: redis-server

# Required-Stop: $syslog
# Should-Start: $local_fs
# Should-Stop: $local_fs
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: redis-server - Persistent key-value db
# Author: Pieter Noordhuis
# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
# the WebSocket protocol implementation in the cramp gem does not work
# well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

joemccann / nginx + node setup.md
Created October 25, 2010 02:06
Set up nginx as a reverse proxy to node.js.

The idea is to have nginx installed and node installed. I will extend this gist to include how to install those as well, but at the moment, the following assumes you have nginx 0.7.62 and node 0.2.3 installed on a Linux distro (I used Ubuntu).

In a nutshell,

  1. nginx is used to serve static files (css, js, images, etc.)
  2. node serves all the "dynamic" stuff.

So for example, www.foo.com request comes and your css, js, and images get served thru nginx while everything else (the request for say index.html or "/") gets served through node.

  1. nginx listens on port 80.

Improve file uploads with Zombie
// Improvements to file uploads with Zombie.
//
// Just start the Sinatra server below and run this file with node.
// Depending on the server used with Sinatra, it will fail upfront or forward
// a bad request to the app. The source code in zombie is in the link below
// (you will need Zombie from git, you can check it out and use `npm link`):
