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)
- 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】

- 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】

- 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 14:49:32]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：
 
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
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。
