大家都知道在speedtest是市面上最准确最全面的测速工具，但在linux命令行不能直接使用，所以我们就借助脚本调用speedtest的接口来利用他测试网速。

1.下载speedtest-cli脚本：

下载地址：https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest_cli.py

wget https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest_cli.py

2.把脚本移动到/usr/local/bin/下面并重命名为speedtest-cli

mv speedtest_cli.py /usr/local/bin/speedtest-cli

3.给脚本赋予权限

cd /usr/local/bin

chmod a+rx speedtest-cli

chown root:root speedtest-cli

4.执行命令speedtest-cli测试网速

[[email protected] ~]# speedtest-cli
