Linux测网速神器之speedtest安装和使用

很多时候我们需要测试Linux服务器的上行和下行宽带。在可用于测试宽带速度的网站中，Speedtest.net也许是使用最广泛的应用“之一”。 Speedtest.net提供了一个命令行版本——speedtest-cli。下面将向你演示如何在Linux的命令行中使用speedtest-cli来测试宽带连接速度。

『工具』VPS常用测试脚本合集 干货分享 第1张

一、安装speedtest-cli
speedtest-cli是一个用Python编写的轻量级Linux命令行工具，在Python2.4至3.4版本下均可运行。它基于Speedtest.net的基础架构来测量网络的上/下行速率。安装speedtest-cli很简，只需要下载其Python脚本文件。步骤如下

wget https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
chmod a+rx speedtest.py
mv speedtest.py /usr/local/bin/speedtest
chown root:root /usr/local/bin/speedtest
二、使用speedtest-cli测试网速
使用speedtest-cli命令也很简单，它不需要任何参数即可工作。

[root@pccv.com ~]# speedtest
输入这个命令后，它会自动发现离你最近的Speedtest.net服务器（地理距离），然后打印出测试的网络上/下行速率

测试结果说明：上行为 4.24Mbit/s 下行为 94.70 Mbit/s ，当然对于测试结果，一般在实际应用中不一定能达到这个值，仅作为参考使用。



speedtest 可以使用 speedtest-cli --list 命令获取 speedtest 的所有测试节点，我们可以配合 grep 命令，得到中国的节点。例如：

speedtest-cli --list | grep China
## 执行此条命令后，即可得到所有中国地区的测速节点
[root@pccv.com ~]# speedtest --list | grep China
