为什么本地开发时使用CURL请求本地URL会卡死

_是在WIN下开发。配置是nignxphp mysql

默认时启动phpcgi是

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;
    }
