FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Installation

1)

brew install nginx
sudo cp /usr/local/Cellar/nginx/1.8.0/homebrew.mxcl.nginx.plist /Library/LaunchAgents

2)

Replace /usr/local/etc/nginx/nginx.conf with the nginx.conf in this gist. I'm using port 5000 for my current project. Obviously, change server_name as well, and probably the name of its access log.

Read Me

In order to access a server hosted within a vm (guest), for development purposes from the host OS, which is restricted to same origin / localhost only requests, I set up a siple nginx reverse proxy to forward my requests.

Steps

To install in a Windows VM, download and install nginx from the current, stable release; I installed to C:\nginx\
Edit the <install path>/conf/nginx.conf file with the marked changes in the file of the same name in this gist.
Start the nginx executable, located in your install path. There are service wrappers for Windows, or you can just kill the process to stop the nginx instance.

Commands for Windows

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

just change out app_name for your purposes

openssl genrsa 2048 > app_name-wildcard.key

openssl req -new -x509 -nodes -sha1 -days 3650 -key app_name-wildcard.key > app_name-wildcard.cert

# Common Name (eg, your name or your server's hostname) []:*.app_name.com

openssl x509 -noout -fingerprint -text &lt; app_name-wildcard.cert &gt; app_name-wildcard.info

	# Here are a simple and quick steps that does exactly this.
	#
	# Let's assume we call "old repo" the repository you wish
	# to move, and "new repo" the one you wish to move to.
	#
	### Step 1. Make sure you have a local copy of all "old repo"
