使用shell并发执行系统命令

一解决方案
二 linux.sh
三 linux_status_redis.php、linux_status.php
四说明

一解决方案

旧方案为挨个执行shell_exec，串行执行，虽然执行很快，奈何监听命令众多，redis连接有等待时间等，有的还需要执行多次取平均值，所以执行完已超过1min

故，改为并发执行命令，单个命令加timeout，则永远可以在10s左右执行完！

golang形式，需要在该php-server上安装go环境，虽然简单，但生产环境尽量不乱动配置
php-swoole形式，同上，一个shell文件而已，没必要挨个server都装拓展
shell的循环&形式，循环体内正则匹配因为本人不熟悉，直接丢给php文件来处理
