This is the OpenResty default page. The server is built on nginx and extended with Lua scripting through ngx_lua. No site or route has been bound to this hostname yet.
/usr/local/openresty/nginx/conf/nginx.conf or add a file under conf.d/.server { ... } block with the desired listen, server_name, and location directives.openresty -s reload.Embed Lua directly inside a location with content_by_lua_block { ngx.say("hello") }. For longer scripts, point content_by_lua_file at a .lua file.
