上行速度

Linux服务器使⽤tc命令对⽹卡流量上下⾏限速

⼀、安装wondershaper软件

由于CentOS7第三⽅库内才有这个软件，先安装第三⽅库

将上⾏带宽限制为1M，下⾏带宽限制为10M

清除原有规则(两个参数可以是任何字符)

查看已有规则(查看eth0的规则)

参数详解

⼀般为3个参数，第⼀个参数为⽹卡名，第⼆个上⾏速度（出）限制，第三个参数为下⾏速度（⼊）限制。

⼆、不愿意下载软件或者没有下载条件的可以使⽤下⾯这种步骤，代码是wondershaper软件内的

1.创建⼀个⽂件，并添加可执⾏权限

2.复制代码下⽅代码到刚刚创建的⽂件内，并放⼊/usr/bin⽬录下
