网卡限速工具,WonderShaper,服务器自我限速

Linux网站管理员

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

 
 
 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。

===以下方式更简单转自1024.Day===

首先更新服务器所有组件：

Debian/Ubuntu: apt -y update && apt -y install wget curl nano zip unzip screen && apt -y upgrade

CentoS/Redhat:  yum -y update && yum -y install wget curl nano zip unzip screen && yum -y upgrade

下载：
git clone https://github.com/magnific0/wondershaper.git
安装：
cd wondershaper
make install
运行:
比如限速200Mbps，注意修改网卡名，可以用 ip a 或者 ifconfig 命令查看网卡名：
wondershaper -a eth1 -d 200000 -u 200000
清空限速：
wondershaper -c -a eth1
后台开机自运行，可以修改配置文件：
vi /etc/systemd/wondershaper.conf
内容如下：
[wondershaper]
# Adapter
IFACE="eth1"
# Download rate in Kbps
DSPEED="200000"
# Upload rate in Kbps
USPEED="200000"
然后启动一下systemd服务就好了：
systemctl enable wondershaper
systemctl start wondershaper
现在我们可以查看状态：
systemctl status wondershaper

退出移动版
