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.

• You have node.js and npm installed on your machine.
• If you use CDF:
  • Use bash or zsh as your shell.

    • prefix=$NODE_HOME
  • $NODE_HOME is the directory in which you have installed node.js.
