由于系统执行一个时间比较长的接口ngxin抛出下面的错误
upstream timed out (10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond) while reading response header from upstream
解决方法：
1，修改fastcgi_read_timeout的参数值，系统默认60秒；
2，fastcgi_read_timeout指定nginx接受后端fastcgi响应请求超时时间 （指已完成两次握手后nginx接受fastcgi响应请求超时时间）
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;
fastcgi_read_timeout 600;
include fastcgi_params;
}
