Homephp教程php手册PHP脚本监控Nginx 502错误并自动重启php-fpm

这篇文章主要介绍了PHP脚本监控Nginx 502错误并自动重启php-fpm,本文直接给出实现代码,然后放到cron中执行,需要的朋友可以参考下

最近服务器时不时出现Nginx 502 Bad Gateway,,如果在电脑旁边还好,要是半夜或者出去了,怎么办?
没关系,写个脚本检测服务状态,发现异常,自动重启。
自动重启脚本:

复制代码 代码如下:


$url = 'http://blog.rebill.info';
$cmd = '/usr/local/php/sbin/php-fpm restart';
 
for($i = 0; $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();
        }
}


原理就是用curl获取HTTP头,发现502状态码就执行重启php-fpm的命令。
url和cmd根据实际情况改成自己的。然后放到crontab里一分钟执行一次。

复制代码 代码如下:


*/1 * * * * /usr/bin/php /root/crontab/nginx502.php


大功告成!
