适用场景：测试宿主机的出公网带宽流量

安装服务speedtest-cli

sudo yum install python-pip
pip install speedtest-cli  # 这里有可能会遇到网络不通，会连接github地址# 建议使用阿里云地址，下面是http，这里可以换成https
pip install -i http://mirrors.aliyun.com/pypi/web/simple  --trusted-host mirrors.aliyun.com speedtest-cli

适用场景：测试两个宿主机之间的带宽流量

安装服务 iperf3

yum -y install iperf3  # 服务端和客户端安装

命令概述

# 服务端 操作命令启动  
]# iperf3 -s  # 输入成功后 宿主机会运行一个服务端程序，上面会启动一个5201端口号提供给客户端连接# 客户端 操作命令 启动 
]# iperf3 -c （10.50.10.202）# 这里输入的IP地址是服务端的IP地址，这里默认连接5201端口，如果服务端非5201 需要-p 指定端口号

示例命令

# 服务端和客户端安装 
yum -y install iperf3
# 服务端 操作命令启动  
]# iperf3 -s # 示例命令  服务端 10.10.78.5
[root@localhost admin]# iperf3 -s
