[root@localhost /]# git clone https://github.com/magnific0/wondershaper.gitwondershaper帮助：
代码语言：javascript复制USAGE: ./wondershaper [-hcs] [-a <adapter>] [-d <rate>] [-u <rate>]
Limit the bandwidth of an adapter
OPTIONS:
-h Show this message
-a <adapter> Set the adpter
-d <rate> Set maximum download rate (in Kbps) and/or
-u <rate> Set maximum upload rate (in Kbps)
-p Use presets in /etc/conf.d/wondershaper.conf
-c Clear the limits from adapter
-s Show the current status of adapter
-v Show the current version
MODES:
wondershaper -a <adapter> -d <rate> -u <rate>
wondershaper -c -a <adapter>
wondershaper -s -a <adapter>
EXAMPLES:
wondershaper -a eth0 -d 1024 -u
512
wondershaper -a eth0 -u 512参数说明：
代码语言：javascript复制-a ：指定要限制的网卡名称或者接口名称
-d ：最大下载速率，单位：Kbps 。Kbps 即 Kb/s，p 是 peer 的意思。1KB/s=8Kb/s。1MB/s=1024KB/s。
-u ：最大上传速率，单位：Kbps 。
-p ：使用 /etc/conf.d/wondershaper.conf 的配置
-c ：清空所有规则，不再做任何限制
-s ：显示接口的当前状态开启限速 给网卡eth0开启限速，设置下载和上传速度分别为8192kbps，即8M带宽
代码语言：javascript复制[root@localhost /]# sh /wondershaper/wondershaper -a eth0 -d 8192 -u 8192
Action 4 device ifb0 ifindex 3注：这里的限速规则，重启服务器后就会失效，可以把命令写进/etc/rc.local，开机自动执行限速命令。
取消限速：
代码语言：javascript复制[root@localhost /]# sh /wondershaper/wondershaper -a eth0 -c查看限速状态：
代码语言：javascript复制[root@localhost ~]# sh /wondershaper/wondershaper -a eth0 -s
