此里所有同php解析的动态内容全部无法打开，想临时解决，重启php-fpm即可(注意:重启nginx无效)，但只治得了一时，于时开始查找解决方案

解决办法

        location ~ \.php$ {

        fastcgi_connect_timeout      180;

        fastcgi_read_timeout         600;

        fastcgi_send_timeout         600;

        fastcgi_pass unix:/tmp/php-fpm.sock;

        fastcgi_index index.php;

        include fastcgi.conf;

        } 

502

的确，504是解决了，但运行一段时间后，又报了502错误

php-fpm日志

[02-Apr-2016 23:24:55] WARNING: [pool www] child 18822, script '/usr/local/nginx/html/phpMyAdmin/import.php' (request: "POST /phpMyAdmin/import.php") execution timed out (340.677871 sec), terminating

[02-Apr-2016 23:24:55] NOTICE: [pool www] child 19164 started

从日志上可以看到， 23:24:55的时，php-fpm的子进程18822因为等待了340.677871秒后被强行终止了并重新生成了一个新的子进程19164

但因为自动生成了新子进程，php网页还是可以正常访问的，只是该查询任务被终止了。
