Nginx configuration file template in nginx.cof

    Used in this project to the Nginx reverse proxy, because it is the first contact with Nginx, it is not very familiar with, but at least now the project can run up to normal, hereby nginx.cof profile content recorded for later viewing.

    In a previous blog, there are about Nginx installation in the windows, as well as some commonly used commands to configure explanation, are interested can look welcome wrong finger. Attach Bowen Address: Nginx explain the installation of windows, run, and configuration files
