lighttpd+fastcgi环境出现500 -Internal Server Error30

配置参考http://quantumflash.blog.hexun.com/11021106_d.html

环境：
ubunut7.10
ruby 1.8.6
rails 2.0.2
lighttpd 1.4.19
gems 1.1.0
fcgi 2.4.0
（主要）安装步骤：
1、源码安装readline
2、源码安装ruby，ruby-zlib
3、源码安装rubygems
4、sudo gem install rails -y
5、sudo gem install fcgi
6、源码安装pcre
7、源码安装lighttpd
在configure时候： ./configure -prefix=/usr/local -with-pcre=/user/local --without-bzip2
8、安装mysql
开始的时候用源码安装的，发现直接解压以后就能用了，怕出错。就用sudo apt-get install mysql-server重新安装了一次。
9、sudo gem install mysql
10、创建一个项目，然后启动服务器script/server，
发现是启动的lighttpd服务器，并同时自动把/usr/local/lib/ruby/gems/1.8/gems/rails-2.0.2/configs/lighttpd.conf拷贝到了当前项目的config目录下面。
发现能打开默认的页面。以为安装成功了。
但是ctrl+c结束服务时候出现：
Couldn't find any pid file in '/u/apps/project/current/tmp/pids'
matching 'dispatch.[0-9]*.pid'
（also looked for process matching "/u/apps/project/current/public/dispatch.fcgi"）
以为是版本的问题，没有特别注意，
然后，修改当前项目下config下的lighttpd.conf文件：

# Default configuration file for the lighttpd web server
# Start using ./script/server lighttpd

server.bind = "200.155.123.13" #（修改过）服务器的IP地址
server.port = 80 #（修改过）改成80号端口

server.modules           = ( "mod_rewrite", "mod_accesslog", "mod_fastcgi", "mod_compress", "mod_expire" )

server.error-handler-404 = "/dispatch.fcgi"
server.pid-file          = CWD + "/tmp/pids/lighttpd.pid"
server.document-root     = CWD + "/public/"

server.errorlog          = CWD + "/log/lighttpd.error.log"
accesslog.filename       = CWD + "/log/lighttpd.access.log"

url.rewrite              = ( "^/$" => "index.html", "^([^.]+)$" => "$1.html" )

compress.filetype        = ( "text/plain", "text/html", "text/css", "text/javascript" )
compress.cache-dir       = CWD + "/tmp/cache"

expire.url               = ( "/favicon.ico"  => "access 3 days",
                             "/images/"      => "access 3 days",
                             "/stylesheets/" => "access 3 days",
                             "/javascripts/" => "access 3 days" )


# Change *-procs to 2 if you need to use Upload Progress or other tasks that
# *need* to execute a second request while the first is still pending.
fastcgi.server      = ( ".fcgi" => ( "localhost" => (
  "min-procs"       => 10,#（修改过）
  "max-procs"       => 10,#（修改过）
  "socket"          => CWD + "/tmp/sockets/fcgi.socket",
  "bin-path"        => CWD + "/public/dispatch.fcgi",
  "bin-environment" => ( "RAILS_ENV" => "production" )#修改过
) ) )

mimetype.assign = (
  ".css"        =>  "text/css",

  ".png"        =>  "image/png",
  ".swf"        =>  "application/x-shockwave-flash",
  ".txt"        =>  "text/plain"
)

# Making sure file uploads above 64k always work when using IE or Safari

}

查了有关材料，发现可能原因：
1、没有分配fastcgi进程
2、lighttpd的数据库模式配置不当
请教如何分配fastcgi进程？怎么配置lighttpd的数据库模式配置？
在进程中：
8251 ?        00:00:00 ruby
8255 ?        00:00:00 lighttpd
8256 ?        00:00:01 dispatch.fcgi <defunct>
8257 ?        00:00:00 dispatch.fcgi <defunct>
8258 ?        00:00:00 dispatch.fcgi <defunct>
8259 ?        00:00:00 dispatch.fcgi <defunct>
8260 ?        00:00:00 dispatch.fcgi <defunct>
8261 ?        00:00:00 dispatch.fcgi <defunct>
8262 ?        00:00:00 dispatch.fcgi <defunct>
8263 ?        00:00:00 dispatch.fcgi <defunct>
8264 ?        00:00:00 dispatch.fcgi <defunct>
9554 ?        00:00:00 sshd
9556 ?        00:00:00 sshd
9557 pts/1    00:00:00 bash
9579 ?        00:00:01 dispatch.fcgi <defunct>
dispatch.fcgi和lighttpd都是存在的。

为空。

这里我把所有的细节都写出来了。希望能得到帮助，可能问题很简单，但是我真的不知道该怎么解决，还请问下lighttpd和fcgi之间工作的原理。谢谢。
问题补充：
谢谢mengwade的回答，你的方法我已经试过了。可是不管用。好像和robbin的配置有点区别。
项目路径是有的：server.document-root = CWD + "/public/"
我还不清楚为什么直接用ruby script/server 就能启动lighttpd服务。以前在red hat上没有这样弄过。

从问题描述来看，是dispatch进程已经死掉了，而lighttpd无法连接dispatch进程。可能你的dispatch进程根本就没有正常启动。实际上在你的配置文件里面也没有任何针对dispatch的配置。

Rails自带的启动lighttpd脚本是ruby编写的，他需要从环境变量里面读取很多配置信息，才能决定如何启动，那么如果有些信息没有的话，启动肯定会失败。建议你不要用Rails的启动脚本，改用lighttpd自己的配置和启动脚本。

虽然lighttpd没有自带ubuntu版本的的启动控制脚本，但是自己写一个很容易，我的博客上面就有

需要在配置文件中指定项目路径的

 1. $HTTP["host"] == "www.xxx.com" {  
   2.  server.document-root = "/yourrails/public"  
   3.  server.error-handler-404 = "/dispatch.fcgi"  
   4.  fastcgi.server = (".fcgi" =>  
   5.     ("localhost" =>  
   6.       ("min-procs" => 10,  
   7.        "max-procs" => 10,  
   8.        "socket" => "/tmp/lighttpd/socket/rails.socket",  
   9.        "bin-path" => "/yourrails/public/dispatch.fcgi",  
  10.        "bin-environment" => ("RAILS_ENV" => "production")  
  11.       )  
  12.     )  
  13.  )  
  14. }
