The erlang_nginx from linearregression

erlang_nginx's Introduction

This is an experimental erlang extension for nginx.

Contributions are welcome. I don't claim to write beautiful c. The biggest thing you can do to help is to show me what I did wrong (nicely) so I can learn from it.

Build

From the nginx source directory, configure nginx with the module included.

$ ./configure --add-module=/path/to/erlang_nginx
$ make
$ make install

Meanwhile

$ erl -setcookie secret -sname handler@localhost
1> P = demo:start().
<x.x.x>

Running nginx and making a curl request ala

$ curl http://localhost/foobar
This...

Results in this output in Erlang:

{Pid, Method, Uri}: {<8207.9.0>, 2, "/foo" ++ _}

Configuration

location /app/ {
    erlang;
    erlang_node handler@localhost;
    erlang_secret secret;
    erlang_registered demo_handler;
}
