记一次失败的Perl + Nginx + FastCGI 配置过程

? 这两天心血来潮，不知道为什么和 Perl + Nginx + FastCGI 配置 耗上了。但是失败了，记录如下：
1）安装Nginx 1.4.3,我的是WINDOWS 7 系统，修改配置文件如下：
?

location ~ .(pl|cgi|perl)?$ {
		    root   var/www/huanghongqiao;
            fastcgi_pass   127.0.0.1:9002;
            fastcgi_index  index.cgi;
            fastcgi_param  SCRIPT_FILENAME  cgi$fastcgi_script_name;
            include        fastcgi_params;
        }

2）安装FCGI 模块，使用 PPM。
?

?右键选择，然后点右上角绿色的箭头。

3）在 var/www/huanghongqiao/cgi 目录下新建 test.PL ，代码如下：

use FCGI;

my $socket = FCGI::OpenSocket( "localhost:9002",5 );
my $request = FCGI::Request( *STDIN,*STDOUT,*STDERR,%ENV,$socket );

my $count;
while( $request->Accept() >= 0 ) {
print "Content-type: text/htmlrnrn";
print "nums is .. ";
print ++$count;
}

FCGI::CloseSocket( $socket );

4） 运行这个test.PL 和 nginx，结果如下图：

5) 从网上下了 nginx-fcgi.pl回来修改，因为它不能在我的windows下运行，估计就是针对linux系统写的。
? 修改后如下代码：

use FCGI;

sub main {
    $socket = FCGI::OpenSocket( "localhost:9002",5 );
	$request = FCGI::Request( *STDIN,%req_params,$socket );
	if ($request) { request_loop()};
		FCGI::CloseSocket( $socket );
}

sub request_loop {
	while( $request->Accept() >= 0 ) {
		# processing any STDIN input from WebServer (for CGI-POST actions)
		$stdin_passthrough = '';
		$req_len = 0 + $req_params{'CONTENT_LENGTH'};
		if (($req_params{'REQUEST_METHOD'} eq 'POST') && ($req_len != 0) ){
			while ($req_len) {
				$stdin_passthrough .= getc(STDIN);
				$req_len--;	
			}
		}
        $file = $req_params{DOCUMENT_ROOT} . '/' . $req_params{SCRIPT_FILENAME};
		$file =~ s@@/@g;
		#我测试过了，得拼接成绝对物理路径
		#我不知道怎么才能用$req_params{SCRIPT_FILENAME}这个相对路径
		#否则提示没有文件。
		if ((-x $file) &&  
			(-s $file) && 
			(-r $file)
		){
			foreach $key ( keys %req_params){
				$ENV{$key} = $req_params{$key};
			}

			open $cgi_app,'-|',$file,$stdin_passthrough or print("Content-type: text/plainrnrn"); print "Error: CGI app returned no output - Executing $req_params{SCRIPT_FILENAME} failed !n"; # addlog($logfile,"Error: CGI app returned no output - Executing $req_params{SCRIPT_FILENAME} failed !");
			
			if ($cgi_app) { 
				print <$cgi_app>; 
				close $cgi_app; 
			}
		} else {
			print("Content-type: text/plainrnrn");
			print "$file size is empty!n" if not -s $file;
			print "$file can't execute!n" if not -x $file;
			print "$file can't readable!n" if not -r $file;
			print "Error: No such CGI app - $file may not exist or is not executable by this process.n";
		}
	}
}
main();

6）test.pl 修改成简单的 print "" 等内容

7）运行这个 nginx-fcgi.pl，打开页面显示：

E:/nginx-1.4.3/var/www/huanghongqiao/cgi/test.pl can't execute!
Error: No such CGI app - E:/nginx-1.4.3/var/www/huanghongqiao/cgi/test.pl may not exist or is not executable by this process.

如果我去掉 (-x $file) 这个测试，errlo.log 里就会显示 ：

2013/10/27 20:20:56 [error] 1496#2172: *45 upstream prematurely closed FastCGI stdout while reading response header from upstream,client: 127.0.0.1,server: localhost,request: "GET /test.pl HTTP/1.1",upstream: "fastcgi://127.0.0.1:9002",host: "localhost:82"

8） 实在不知道怎么弄了，难道和 execute 有关系吗？Windows下不知道怎么修改可执行呢？？？？
