导致这个问题的原因很多
解决：设置一下参数，重启php服务
设置参数可以参考：

/home/lnmp/ restart
如果重启出现这个问题：
Stoping LNMP... Nginx program is stop Shutting down php_fpm /usr/local/php/sbin/php-fpm: line 69: kill: (499) - No such process ................................... failed PHP-FPM program is stop Shutting down MySQL. SUCCESS! MySQL program is stop Starting LNMP... Nginx start successfully! php-fpm is runing! Starting MySQL. SUCCESS! MySQL start successfully!
则：/usr/local/php/sbin/php-fpm restart
再试过几次
