在Ubuntu下安裝lightTPD的並運行PHP，Rails。

$ sudo apt-get install lighttpd php5-cgi

$ sudo lighty-enable-mod fastcgi

$ sudo vim /etc/lighttpd/conf-enabled/10-fastcgi.conf

修改結果如下：

server.modules   += ( "mod_fastcgi" )

## Start an FastCGI server for php4 (needs the php4-cgi package)
fastcgi.server    = ( ".php" =>  
    ((  
        "bin-path" => "/usr/bin/php-cgi",
        "socket" => "/tmp/php.socket",
        "max-procs" => 1,
        "idle-timeout" => 20, 
        "bin-environment" => ( 
            "PHP_FCGI_CHILDREN" => "2",
            "PHP_FCGI_MAX_REQUESTS" => "10000"
        ),
        "bin-copy-environment" => (
            "PATH", "SHELL", "USER"
        ),
        "broken-scriptfilename" => "enable"
    ))  
)

其他配置：

$HTTP["host"] == "newweb.im.ac.cn" {
    server.document-root = "/var/www/"
}

# Rails Test
$HTTP["host"] == "localhost" {
      server.document-root = "/soft/www/rails/demo/public" 
      alias.url = ( "/myrailsapp" => "/soft/www/rails/demo/public" )
      accesslog.filename   = "/soft/www/rails/demo/log/access.log" 
      server.error-handler-404 = "dispatch.fcgi" 
      server.errorlog          = "/soft/www/rails/demo/log/lighttpd.error.log" 
      server.indexfiles = ( "index.html" , "dispatch.fcgi" )
      # rails stuff
      fastcgi.server = ( ".fcgi" =>
      (
        (
            "socket" => "/soft/www/rails/demo/log/code.socket",
            "min-procs" => 2,
            "max-procs" => 2,
            "bin-path" =>  "/soft/www/rails/demo/public/dispatch.fcgi",
            "bin-environment" => ( "RAILS_ENV" => "development" )
        )))
}   

注意打開evhost模塊。
