Hello all, I have created two Github Gists for detailed step-by-step instructions on installing the latest Ghost Blog with Nginx and ModSecurity or Naxsi. Blogging is a good way to utilize any idle VPS you have! The instructions have been successfully tested on Ubuntu 12.04 LTS Server (freshly installed). However, use at your own risk. To configure extra features, see my blog articles here and here.
