1.什么是WonderShaper

WonderShaper是用来对特定网卡进行快速限速的工具,它实际是对Linux的tc命令进行封装后的shell脚本,所以使用成本比tc更低,更容易上手,以下配合测速工具speedtest一起使用

2.如何安装WonderShaper

#直接拉取wondershaper,开箱即用
git clone https://github.com/magnific0/wondershaper.git

root@****-5491:/home/soft/wondershaper# ./wondershaper -v
Version 1.4.1
root@****-5491:/home/soft/wondershaper# 

#网速测试工具speedtest安装(Ubuntu)
apt install speedtest-cli
--yum install speedtest-cli (centos) 

3.WonderShaper使用帮助

root@****-5491:/home/soft/wondershaper# ./wondershaper -h
USAGE: ./wondershaper [-hcs] [-a <adapter>] [-d <rate>] [-u <rate>]

Limit the bandwidth of an adapter

OPTIONS:
   -h           Show this message 【帮助信息】
   -a <adapter> Set the adapter  【指定网卡接口】
   -d <rate>    Set maximum download rate (in Kbps) and/or 【限制下载速度(Kbps)】
   -u <rate>    Set maximum upload rate (in Kbps)   【限制上传速度(Kbps)】
   -p           Use presets in "/etc/systemd/wondershaper.conf"
   -f <file>    Use alternative preset file
   -c           Clear the limits from adapter 【清除指定网卡规则,用于取消限速】
   -s           Show the current status of adapter 【显示当前网卡的状态】
   -v           Show the current version  【显示当前版本】

   Configure HIPRIODST in "/etc/systemd/wondershaper.conf" for hosts
   requiring high priority i.e. in case ssh uses dport 443.

MODES:
   wondershaper -a <adapter> -d <rate> -u <rate>
   wondershaper -c -a <adapter>
   wondershaper -s -a <adapter>

EXAMPLES: 【使用示例】
   wondershaper -a eth0 -d 1024 -u 512  【设置网卡eth0的上行速度为512kbps,下行速度为1024kbps】
   wondershaper -a eth0 -u 512 【只设置上行速度为512kbps】
   wondershaper -c -a eth0 【清除网卡eth0的规则】
   wondershaper -p -f foo.conf 【设置指定的配置文件】

5.WonderShaper在测试中的应用

  • 测试项目:某内部数据库迁移工具
  • 测试目的:数据迁移中,对目标端进行限速,当取消限速后,传输速度可以恢复
  • 测试步骤:起迁移进程,在目标端服务器上用WonderShaper工具进行限速:

-- 只限制下行速度
[#22#root@**** ~/wondershaper]22  ./wondershaper -a enp0s3  -d 100
  • 测试结果:限速后,写目标库单位写入行数和单位写入字节数都急剧下降,如下图:

取消限速,恢复网络后,传输速率慢慢恢复:

6.网速单位转换

1KB/s = 8kbps = 8kb/s
比如一般100M的宽带,实际是100Mbps=(100/8) MB/s=12.5 MB/s

7.总结

使用WonderShaper对网卡进行限速,在测试时可以针对性的指定网卡,指定上传速度或者指定下载速度,在测试中上传和下载速度是互不影响的,可以只限制一方;且WonderShaper工具操作简单好入手,是个不错的工具。
