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( $request->Accept() >= 0 ) {print "Content-type: text/html\r\n\r\n";print "nums is .. ";print ++$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, \*STDOUT, \*STDERR, \%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} . '/����,ǿ��' . $req_params{SCRIPT_FILENAME};$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/plain\r\n\r\n"); 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 ; close $cgi_app; }} else {print("Content-type: text/plain\r\n\r\n");print "$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？？？？
