Linux 下 网速测试

电脑测试网速这个功能估计大家都用过，但是服务器需要测试外网的速度相比大家做法各有不同，有的人使用自己的服务器来测试上下行速度，有些通过下载某个网站的资源来测试下行速度，鉴于这些节点比较少，而且测试麻烦，我向大家推荐speedtest－cli.
speedtest是一个使用python编写的命令行脚本，通过调用speedtest.net测试上下行的接口来完成速度测试.最后我会测试运维生存时间所在服务器的外网速度。

1. 安装speedtest-cli

speedtest-cli需要在python 2.4-3.4的环境下，安装方法都很简单，自己选择以下最适合你的一种.

1.1 pip方式

什么是 pip 传送门>

  1. pip3 install speedtest-cli

1.2 github＋pip方式

  1. pip3 install git+https://github.com/sivel/speedtest-cli.git

或者

  1. git clonehttps://github.com/sivel/speedtest-cli.git
  2. python speedtest-cli/setup.py install

1.3 下载脚本方式

前提是你要能上 Github

  1. curl -oL speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
  2. chmod 777 speedtest-cli
  3. ./speedtest-cli

2. speedtest－cli用法 命令很简单，直接上帮助

  1. speedtest-cli --help
  1. usage: speedtest-cli [-h] [--no-download] [--no-upload] [--single] [--bytes]
  2.                      [--share] [--simple] [--csv]
  3.                      [--csv-delimiter CSV_DELIMITER] [--csv-header] [--json]
  4.                      [--list] [--server SERVER] [--exclude EXCLUDE]

4. speedtest-cli测试


4.1 列出所有在中国的测试服务器

  1. speedtest-cli --list | grep China

[root@li229-122~]# speedtest-cli —list | grep China 1185)China Unicom(Changchun,China)[10534.35km] 3784)China Mobile(Urumqi,China)[10581.15km] 2667)Beijing Normal University(Beijing,China)[11117.03km] 2529)Beijing Normal University(Beijing,China)[11117.03km] 2816)Capital Online Data Service(Beijing,China)[11117.03km] 4354)SXmobile(Taiyuan,China)[11383.17km] 3973)China Telecom(Lanzhou,China)[11615.43km] 3633)China Telecom(Shanghai,China)[11983.37km] 3927)China Mobile Jiangsu Co.,Ltd.(Suzhou,China)[11989.27km] 2461)China Unicom(Chengdu,China)[12213.35km] 1028)Shepherd Software(Xiamen,China)[12785.57km] 1628)Xiamen Guangdian Xinxu(Xiamen,China)[12785.57km] 3891)GZinternet(Guangzhou,China)[13005.36km] 3871)SZWCDMA(Shenzhen,China)[13059.20km] 3819)SZU(Shenzhen,China)[13059.20km] 1536)STC(Hong Kong,China)[13088.37km] 1890)Telin(Hong Kong,China)[13088.37km]

结果解释
3633) China Telecom (Shanghai, China) [11983.37 km]
3633: 服务器id
china telecom：isp，这里是中国电信
shanghai,china ：服务器所在地址
11983.37 km：两台服务器地理位置之间距离，我这台机器在美国，和上海相距11983.37公里，很远呐.

4.1 外网速度测试
服务器在美国linode，我测试到上海这台机器的速度，并且生成图片报告

  1. speedtest-cli --server=3633 --share

[root@li229-122~]# speedtest-cli —server=3633 —share Retrieving speedtest.net configuration… Retrieving speedtest.net server list… Testing from Linode(173.255.219.122)… Hosted by China Telecom(Shanghai)[11983.37km]:23.603ms Testing download speed…………………………………. Download:24.84Mbit/s Testing upload speed………………………………………….. Upload:4.57Mbit/s Share results:http://www.speedtest.net/result/3240988007.png

通过结果可以看到，上海电信用户访问www.ttlsa.com可以达到4.57mbit，上传到www.ttlsa.com可以达到28.84mbit/s. share参数的效果图如下：
