Centos安装 络测速软件-Speedtest

1.查看系统版本

[root@ecloud ~]# cat /etc/redhat-release CentOS release 6.5 (Final)[root@ecloud ~]# [root@ecloud ~]# uname -r2.6.32-431.el6.x86_64[root@ecloud ~]# 

2.主机能ping 通外

[root@ecloud ~]# ping qq.comPING qq.com (14.17.32.211) 56(84) bytes of data.64 bytes from 14.17.32.211: icmp_seq=1 ttl=51 time=3.76 ms64 bytes from 14.17.32.211: icmp_seq=2 ttl=51 time=3.66 ms64 bytes from 14.17.32.211: icmp_seq=3 ttl=51 time=3.66 ms64 bytes from 14.17.32.211: icmp_seq=4 ttl=51 time=3.69 ms

3.Speedtest介绍

Speedtest强大而知名的全球宽带 络速度测试工具，采用Flash载入界面，Alexa世界排名非常高，Speedtest.net在全球有数百个测试节点，国内有测速节点几十个。作为一款在线并且可视化的 速测试工具。Speendtest.net官 ：http://www.speedtest.net/

工作原理：它在你的浏览器中加载JavaScript代码并自动检测离你最近的Speedtest.net服务器，然后向服务器发送HTTP GET and POST请求来测试上行/下行 速

Speedtest支持Windowst和Linux操作系统

Windows系统直接在浏览器输入 www.speedtest.net进行测试即可

Linux系统需要在对speedtest进行安装

4.在Linux安装speedtest-cli

a.安装pip

speedtest使用的是python写的，没使用过pip的需要先安装pip
