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。

#!/usr/bin/php
<!--$url = 'http://www.deepvps.com';
$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();
        }
}
-->

至于crontab，请自行Google搜索
