Updating Nginx

gistfile1.txt

The first step is to make sure you have ruby installed. Then gem install passenger

If you're upgrading mothership, download the Nginx-upload-module. Otherwise, just ignore all instructions regarding it.
http://www.grid.net.ru/nginx/upload.en.html (scroll almost to the bottom or search for Download)
extract that into whatever directory you want

download and extract Nginx source http://nginx.org/
run the passenger install script (passenger-install-nginx-module)
tell passenger you want to compile nginx from source. You'll want to do the following:
  - tell it to install nginx in /opt/nginx
  - tell it to install the nginx-upload-module (as well as where the source for that is)

I think that's about it. Be sure not to lose the current config files.
