HTTP/HTTPS server farm made easy

Provides means to scale HTTP/HTTPS servers in unobtrusive way. Uses haproxy as reverse proxy and load balancer for HTTP, and stud as HTTPS terminator. Supports socket.io. Serves permissive Flash Sockets Policy.

How to Install

apt-get install runit libev-dev libssl-dev uuid-dev
npm install farm

Go to ~/node_modules/farm and run

Now you have haproxy listening to :80 for HTTP and :65443 for HTTPS terminated by stud listening to :443.

How to use

Edit /etc/service/haproxy/haproxy.conf and /etc/service/stud/run. Changes you might want to make are marked with 'CONFIG:'.

N.B. Your server should respond to health requests emitted by haproxy to ensure the farm node is alive and functional. You can simply prepend your middleware with bundled connect-compatible handler found at node/health.js:

app.use(require('lib/health')());

Example

cd node
node example.js
open http://localhost
open https://localhost
