CPU利用太高了。。。高手帮忙解决一下。。。谢谢了。

系统平均负载3.75 3.37 2.43 4/85
运行了几个纯php程序是不是太资源了？？

置顶帖502排查里的https://bbs.vpser.net/thread-1654-1-1.html 试试

sofeng 发表于 2012-6-14 01:36:27

改了改 希望可以加了个重启脚本，，希望可以对大家有帮助。

LNMP-502自动重启脚本

   使用lnmp的同学经常会遇到nginx出现502的情况，有些时候无论怎么调整，都不能解决问题，如果在睡觉的时候出现问题，而自己又没有检查，那流量不就白白浪费了吗？
   下面我介绍一种方法，完全可以监测到502然后自动重启php-fpm

在SSH中新建一个文件
SSH中输入：

vi 502.sh
在文件中输入如下内容
#!/usr/bin/php
<?
$url = 'https://www.vpser.net';
$cmd = '/usr/local/php/sbin/php-fpm restart';

for($i = 0; $i < 5; $i ++){
$exec = "curl --connect-timeout 3 -I $url 2>/dev/null";
$res = shell_exec($exec);

if(stripos($res,'502 Bad Gateway') !== false){
shell_exec($cmd);
exit();
}
}
?>
然后保存，其中的网址设置你这台VPS上的任意网页


赋予777权限


chmod 777 /root/502.sh
下一步我们设置上定时

crontab使用方法

SSH中输入crontab -e

输入：

*/1 * * * * /root/502.sh
这样就可以自动检测网页如果是502 就自动重启
