Allow Node.js to bind to privileged ports without root access on Ubuntu

How to: Allow Node to bind to port 80 without sudo

TL;DR

Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024

sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node

Important: your node location may vary. Use which node to find it, or use it directly in the command:

Configuring an AWS Elastic Load Balancer for a Node.js application using WebSockets on EC2

AWS ELB with Node.js and WebSockets

This assumes that:

  • You are using Nginx.
  • You want to accept incoming connections on port 80.
  • Your Node.js app is listening on port 3000.
  • You want to be able to connect to your Node.js instance directly as well as via the load balancer.

####1. Create load balancer

Set up nginx and uwsgi emperor on a CentOS 6.7 box
# GOAL: On a CentOS 6.7 minimal install, set up nginx as a reverse proxy to uWSGI Emperor with python 2.7.11 as a plugin to run Flask apps
# ::NOTE:: All instructions below are run as a sudoer, not as root. Talk to your sysadmins if you're not a sudoer.
# Install bare essentials:
sudo yum install -y epel-release
sudo yum groupinstall 'Development Tools'
sudo yum install -y vim openssl unzip nginx openssl-devel zlib-devel sqlite-devel bzip2-devel libffi-devel lapack-devel blas-devel libpng-devel freetype-devel
# Set SELINUX=disabled in the file below, and reboot, or this tutorial will get unnecessarily complicated:
