#### 如何进行linux带宽测试
5. how to test NetWidth :
###
5.1 method1 to see (https://blog.csdn.net/Deronn/article/details/86682715):
1.从github克隆包到本地
# git clone https://github.com/sivel/speedtest-cli.git
2.执行speedtest这个python脚本
python speedtest.py
####
5.2 method2 python test like following (#todo Suggest you use this!!!):
安装命令：
wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
chmod a+x speedtest-cli
运行命令：
./speedtest-cli
##
5.3 method3,环境CentOS7_x86_64:(https://blog.51cto.com/13718210/2418661)
a. 测试网络带宽常用命令(包含安装使用)
yum -y install iperf
b. 测试时记得关闭防火墙或者自行配置防火墙规则，为了快速测试，这里就直接关闭防火墙
systemctl stop firewalld
c. 安装完iperf后，在Server端执行
#todo[root@110_152 ~] iperf -s -i 1 -f m
-s表示server，-i表示显示时间间隔，-f表示显示格式化的单位
打开第二台linux 作为client端，安装iperf执行:
#todo[root@110_152 ~] iperf -c host_server_ip -i 1 -t 30 -f m
-c表示客户端，后面接server的地址，-t代表运行的时间
#todo [root@110_152 ~]# iperf -c 192.168.110.151 -i 1 -t 30 -f m
