@xinqiyang you didn't look closer enough :)

You need the "websocket" git branch in the ngx_lua github repository for now because this thing is not yet merged into the master branch nor getting included in any ngx_openresty releases.

To quote the related part in that blog post:

$ git clone https://github.com/chaoslawful/lua-nginx-module.git
$ cd lua-nginx-module
$ git checkout -b websocket origin/websocket
$ cd ../ngx_openresty-1.4.2.7/bundle
$ rm -Rf ngx_lua-0.8.9
$ ln -s ../../lua-nginx-module ngx_lua-0.8.9

Anyway, I'm going to merge the websocket branch into master in the next few days or so.
