LigHTTPD + RoR: "spawning fcgi failed"

Question

I'm trying to set up Ruby on Rails on lighttpd. The operating system is CentOS, though it may be notable that this is a Xen-based VPS.

The problem occurs something like this:

bash-3.2# /etc/rc.d/init.d/lighttpd start
Starting lighttpd:                                         [  OK  ]
bash-3.2# /etc/rc.d/init.d/lighttpd status
lighttpd dead but pid file exists

The error log reports...

    You can find out if it is the right one by executing 'php -v' and it should disp

mod_fastcgi is enabled.

As far as I can tell, the relevant configuration in the Lighttpd file is

    fastcgi.server =  (".fcgi" => ( "rails" =>
      ( "min-procs" => 1,
        "max-procs" => 2,
        "socket" => "/tmp/lighttpd-fcgi.socket",
        "bin-path" => "/var/www/rails/ToDo/public/dispatch.fastcgi"
      )
    ))

dispatch.fastcgi is set to executable.

I'm not really sure what's going on.

Answer 1

Does the first line with the path to the Ruby interpreter in dispatch.fastcgi look right?
