Speedtest-CLI是Speedtest.net旗下一个开源的一键测速脚本，可以一键测试Linux系统服务器就近节点的上传及下载速度，也可以一键测试Linux系统服务器到指定节点的速度，还可以一键获取Linux系统服务器就近节点的Speedtest测速节点。关于Speedtest-CLI相对以前是可以获取全部节点列表的，目前最多只能获取就近10个左右的节点！由于Speedtest-CLI一键测速脚本可能在后面需要用得到，主机玖玖这里记录一下，方便以后查找。
如果需要较为全面的Speedtest测速脚本，可以查看下面文章：
一、Speedtest-CLI一键测速脚本安装
1、如果你的系统之前安装过Speedtest-CLI旧版本，请先执行下面命令卸载，然后在安装。
# Ubuntu/Debian系统卸载请执行下面命令 www.zhuji999.com：
sudo rm /etc/apt/sources.list.d/speedtest.list
sudo apt-get update
sudo apt-get remove speedtest
sudo apt-get remove speedtest-cli
# CentOS/Fedora/Redhat系统卸载请执行下面命令www.zhuji999.com：
sudo rm /etc/yum.repos.d/bintray-ookla-rhel.repo
sudo yum remove speedtest
rpm -qa | grep speedtest | xargs -I {} sudo yum -y remove {}
2、Ubuntu/Debian系统安装命令：
apt install -y curl curl -s https://install.speedtest.net/app/cli/install.deb.sh | sudo bash sudo apt-get install speedtest
3、CentOS/Fedora/Redhat系统安装命令：
yum install -y curl curl -s https://install.speedtest.net/app/cli/install.rpm.sh | sudo bash sudo yum install speedtest
二、Speedtest-CLI一键测速命令
用上面的脚本安装好Speedtest-CLI测速程序后，可以选择使用下面命令来进行测速。
1、直接测速服务器就近节点速度。属于“speedtest”执行即可。
speedtest
测速结果如下：
[root@C20220807179539 ~]# speedtest
Speedtest by Ookla
Server: wuhan hello 5G - Wuhan (id: 29353)
ISP: CloudITIDC Global
Idle Latency: 33.02 ms (jitter: 0.42ms, low: 32.36ms, high: 33.95ms)
Download: 1.83 Mbps (data used: 2.9 MB)
28.54 ms (jitter: 20.13ms, low: 26.68ms, high: 824.93ms)
Upload: 9.57 Mbps (data used: 4.3 MB)
30.50 ms (jitter: 2.13ms, low: 25.04ms, high: 38.24ms)
Packet Loss: Not available.
Result URL: https://www.speedtest.net/result/c/e2c8e53d-bdc3-44bd-ab6b-a98f90c903fa
2、查看服务器最新测速节点列表。
speedtest -L
测试结果如下：
[root@C20220807179539 ~]# speedtest -L
Closest servers:
ID Name Location Country
==============================================================================
41910 China Mobile Henan 5G Zhengzhou China
36646 China Unicom HeNan 5G Zhengzhou China
44176 河南移动5G Zhengzhou China
17145 China Telecom AnHui 5G Hefei China
26404 安徽移动5G Hefei China
29353 wuhan hello 5G Wuhan China
23844 China Telecom Wuhan Branch Wuhan China
26352 China Telecom JiangSu 5G Nanjing China
35722 China Telecom TianJin TianJin China
5317 江苏电信5G Yangzhou China
[root@C20220807179539 ~]#
除了上述可以通过服务器使用“speedtest -L”命令来查看服务器最近测速节点玩，我们目前还可以通过访问下面两个网站地址来查找距离我们本地或者访问网站的服务器较近的SpeedTest测速节点。
- https://c.speedtest.net/speedtest-servers-static.php
- https://www.speedtest.net/api/android/config.php
3、测试服务器到指定节点的速度。注意下面代码当中的“99999”请用节点ID代替。如测试“5317 江苏电信5G Yangzhou China”这个节点，我们用“speedtest -s 5317”来测试结果。
speedtest -s 99999
“speedtest -s 5317”测速结果。
[root@C20220807179539 ~]# speedtest -s 5317
Speedtest by Ookla
Server: 江苏电信5G - Yangzhou (id: 5317)
