Installing Node.js on Amazon Linux AMI

The following will guide you through the process of installing Node.js on an AWS EC2 instance running Amazon Linux AMI 2016.09 - Release Notes

For this process I'll be using a t2.micro EC2 instance running Amazon Linux AMI (ami-d41d58a7). Once the EC2 instance is up-and-running, connect to your server via ssh

Make sure our server has the latest packages : sudo yum update -y

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Client-side SSL

For excessively paranoid client authentication.

Using self-signed certificate.

Create a Certificate Authority root (which represents this server)

Organization & Common Name: Some human identifier for this server CA.

openssl genrsa -des3 -out ca.key 4096
openssl req -new -x509 -days 365 -key ca.key -out ca.crt
