我是在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;
}
