[Nix-dev] lighttpd service

[Rickard Nilsson]

Hi Alexander,

I have no troubles running av minimal lighttpd on NixOS. I can start and  
stop it with upstart. My configuration looks like this:

let

   root = "/srv/www";
   httpPort = 3000;

   httpConf = writeText "webserver.conf" ''
     server.document-root = "${root}"
     server.port = ${httpPort}
   '';

in {

   jobs.webserver = {
     path = [ lighttpd ];
     exec = "lighttpd -D -f ${httpConf}";
   };

}


Regards,
   Rickard Nilsson
