突发服务器问题解决，nginx
下午可能是因为阿里的以此误处理，他认为我自己的IP在攻击我的服务器，所以把我的IP给封掉了，导致这个地址不能访问自己的网站，开始以为是不是自己的服务器有问题，对服务器进行了重启，但是没有效果，后来发现可能问题出在阿里服务器那端封了我的服务器，大概1小时候，网站就恢复了，估计是阿里云进行了处理，但是登录网站后台却出现了如下问题。
只看报错是发现不了问题的，必须查看日志文件

发现是在调用php文件时抱错，从网上搜索到的信息来看，可能是php-fpm这个服务没有启动，因为刚刚重启动了服务器，应该是启动过程中php-fpm并没有启动，
chkconfig --list | grep php-fpm
php-fpm 0:off 1:off 2:off 3:off 4:off 5:off 6:off
发现确实这个并没有随系统启动，问题找到之后通过/etc/init.d/php-fpm restart实现重启，同时把这个设置为随系统启动
chkconfig php-fpm on;
chkconfig --list | grep php-fpm;
php-fpm 0:off 1:off 2:on 3:on 4:on 5:on 6:off
设置完成，这样问题就圆满解决了，但是阿里云存在的误报错的问题，不知道后面会不会好一些，不再出现。
