Answer 1

By default, OpenResty's nginx is installed into the path /usr/local/openresty/nginx/sbin/nginx. Your system's default nginx init configurations need an update to point to the right locations.

It seems to me, as if you haven't installed the right module? ngx_lua (http://wiki.nginx.org/HttpLuaModule)

You mention OpenResty. Did you configure it with lua? If not, the guide is here(http://wiki.nginx.org/HttpLuaModule#Installation).
Quick resumé:

The ngx_openresty bundle can be used to install Nginx, ngx_lua, either one of the standard Lua 5.1 interpreter or LuaJIT 2.0, as well as a package of powerful companion Nginx modules. The basic installation step is a simple ./configure --with-luajit && make && make install.

You can manually compile ngx_lua into nginx too, the full guide is in the link too.

After comment-discussing - I removed the irrelevant part of the answer.
