NAME ^

Plack::Handler::FCGI - FastCGI handler for Plack

SYNOPSIS ^

  # Run as a standalone daemon
  plackup -s FCGI --listen /tmp/fcgi.sock --daemonize --nproc 10

  # Run from your web server like mod_fastcgi
  #!/usr/bin/env plackup -s FCGI
  my $app = sub { ... };

  # Roll your own
  my $server = Plack::Handler::FCGI->new(
      nproc  => $num_proc,
      listen => [ $port_or_socket ],
      detach => 1,
  );
  $server->run($app);

DESCRIPTION ^

This is a handler module to run any PSGI application as a standalone FastCGI daemon or a .fcgi script.

OPTIONS

listen
    listen => [ '/path/to/socket' ]
    listen => [ ':8080' ]

Listen on a socket path, hostname:port, or :port.

port

listen via TCP on port on all interfaces (Same as listen => ":$port")

leave-umask

Set to 1 to disable setting umask to 0 for socket open

nointr

Do not allow the listener to be interrupted by Ctrl+C

nproc

Specify a number of processes for FCGI::ProcManager

pid

Specify a filename for the pid file

manager

Specify a FCGI::ProcManager sub-class

daemonize

Daemonize the process.

keep-stderr

Send STDERR to STDOUT instead of the webserver

WEB SERVER CONFIGURATIONS

nginx

This is an example nginx configuration to run your FCGI daemon on a Unix domain socket and run it at the server's root URL (/).

  http {
    server {
      listen 3001;
      location / {
        set $script "";
        set $path_info $uri;
        fastcgi_pass unix:/tmp/fastcgi.sock;
        fastcgi_param  SCRIPT_NAME      $script;
        fastcgi_param  PATH_INFO        $path_info;
        fastcgi_param  QUERY_STRING     $query_string;
        fastcgi_param  REQUEST_METHOD   $request_method;
        fastcgi_param  CONTENT_TYPE     $content_type;
        fastcgi_param  CONTENT_LENGTH   $content_length;
        fastcgi_param  REQUEST_URI      $request_uri;
        fastcgi_param  SERVER_PROTOCOL  $server_protocol;
        fastcgi_param  REMOTE_ADDR      $remote_addr;
        fastcgi_param  REMOTE_PORT      $remote_port;
        fastcgi_param  SERVER_ADDR      $server_addr;
        fastcgi_param  SERVER_PORT      $server_port;
        fastcgi_param  SERVER_NAME      $server_name;
      }
    }
  }

If you want to host your application in a non-root path, then you should mangle this configuration to set the path to SCRIPT_NAME and the rest of the path in PATH_INFO.

See http://wiki.nginx.org/NginxFcgiExample for more details.

Apache mod_fastcgi

You can use FastCgiExternalServer as normal.

  FastCgiExternalServer /tmp/myapp.fcgi -socket /tmp/fcgi.sock

See http://www.fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html#FastCgiExternalServer for more details.

lighttpd

To host the app in the root path, you're recommended to use lighttpd 1.4.23 or newer with fix-root-scriptname flag like below.

  fastcgi.server = ( "/" =>
     ((
       "socket" => "/tmp/fcgi.sock",
       "check-local" => "disable"
       "fix-root-scriptname" => "enable",
     ))

If you use lighttpd older than 1.4.22 where you don't have fix-root-scriptname, mouting apps under the root causes wrong SCRIPT_NAME and PATH_INFO set. Also, mouting under the empty root ("") or a path that has a trailing slash would still cause weird values set even with fix-root-scriptname. In such cases you can use Plack::Middleware::LighttpdScriptNameFix to fix it.

To mount in the non-root path over TCP:

  fastcgi.server = ( "/foo" =>
     ((
       "host" = "127.0.0.1"
       "port" = "5000"
       "check-local" => "disable"
     ))

It's recommended that your mount path does NOT have the trailing slash. If you really need to have one, you should consider using Plack::Middleware::LighttpdScriptNameFix to fix the wrong PATH_INFO values set by lighttpd.
