A URL Shortener with analytics based on Nginx and Redis

• Start a redis instance
• Build your nginx with lua-nginx-module and set-misc-nginx-module
• Copy the lua script conf/lua/n3r/urlshortener_eval.lua to your own nginx conf/lua/n3r/ directory, and update the redis configurations in the connect function
• Copy the html/shorten-ui.html to your own nginx html directory
• Download lua-resty-redis and copy the lib/resty/redis.lua to your own nginx conf/lua/resty/ directory
• Add the follow configurations to your nginx.conf, then start your nginx

http block: lua_package_path

server block: location a)shorten-ui.html b)shorten c)^/0[0-9a-zA-Z]{1,12}$

You could find these configurations in my conf/nginx.conf

http://localhost:8088/shorten?url=http://www.google.com

NOTE: Do not forget the http:// prefix within the url parameter

Just visit the url that the previous step returned

http://localhost:8088/shorten-ui.html

NOTE: In this page, you could input a URL, then get the shorten form

http://localhost:8088/shorten?url=http://www.google.com&random=true
