The Problem

Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.)

The temptingly easy but ultimately wrong solution:

Alter the port the script talks to from 8000 to 80:

}).listen(80);

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

install packages for vim, git
create user accounts, as specified in included JSON config files
install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

	yum install fontconfig freetype freetype-devel fontconfig-devel libstdc++
	wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.8-linux-x86_64.tar.bz2
	tar -xjvf ~/downloads/phantomjs-1.9.8-linux-x86_64.tar.bz2 --strip-components 1 /opt/phantomjs/
	sudo yum install libffi-devel openssl-devel
	pip install pyopenssl pyasn1
	pip install requests[security]

	-Go to the starting point of the project
	>> git checkout origin master
	-fetch all objects
	>> git fetch origin
	-Make the branch from the tag
	>> git branch new_branch tag_name
	-Checkout the branch
	>> git checkout new_branch
	-Push the branch up
	>> git push origin new_branch
