I'm not sure which OS you are in, but setting up ngx_openresty 
should be as simple as
tar -xzvf ngx_openresty-0.8.54.1.tar.gz
vi /path/to/my/nginx.conf # edit it!
/usr/local/openresty/nginx/sbin/nginx -c /path/to/my/nginx.conf # start it!
The ngx_openresty bundle contains nginx 0.8.54, the standard lua 5.1
interperter, the ngx_lua module, and many other goodies. It has been
tested on both Linux and Solaris, but should also work in other OS's
like Mac OS X and *BSD. Feedback welcome!
