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

Grr this took hours to figure out. I was trying to install MJPG-streamer and running VLC command lines and all this crap but nothing worked.

First install motion:

~> sudo apt-get install motion

Then create a config file:

~> mkdir ~/.motion

~> nano ~/.motion/motion.conf
