PHP 本地发起同域名下CURL卡死现象解决方案

http://blog.51cto.com/aarons/1583871 感谢！！！

D:\php \php-cgi.exe-b 127.0.0.1:9000 -c D:\phpfind\phpa\php.ini

先看NGINX配置

location ~ \.php(.*)$  {
   fastcgi_pass   127.0.0.1:9000;
   fastcgi_index  index.php;
   fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
   fastcgi_param  PATH_INFO  $fastcgi_path_info;
   fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
   include        fastcgi_params;
}

NGINX中，看PHP文件块fastcig-pass的设置值(127.0.0.1:9000)。设置都是以keepalive方式请求，接收到PHP文件时，交于后端过程PHPCGI解析处理(127.0.0.1:9000)，等待响应。而在本地文件以CURL请求本地环境中PHP文件时，之前的PHP还在等待CURL后的结果，这时9000端口已经被占用。导致CURL一直在处于等待状态。不设置timeout超时，程序就会卡死。结果都是false 解决方案:
新开启一个phpcgi进程设置不同端口：
例

D:\php\php-cgi.exe -b 127.0.0.1:9001 -c D:\phpfind\phpa\php.ini

在需要被CURL的端口或域名设置中设置。

location ~ \.php(.*)$  {
           fastcgi_pass   127.0.0.1:9001;
           fastcgi_index  index.php;
           fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
           fastcgi_param  PATH_INFO  $fastcgi_path_info;
           fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
           include        fastcgi_params;
}

这样就可以请求了。但是不能请求同一个域下的文件。
这样可以在nginx中使用php-cgi负载均衡：

upstream backend{
    server 127.0.0.1:9000;
    server 127.0.0.1:9001;
}
location ~ \.php(.*)$  {
    fastcgi_pass   backend;
    fastcgi_index  index.php;
    fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    fastcgi_param  PATH_INFO  $fastcgi_path_info;
    fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
    include        fastcgi_params;
}
