linux（centos）測試帶寬

1.安裝speedtest-cli

speedtest-cli是一個用Python編寫的輕量級Linux命令行工具，在Python2.4至3.4版本下均可運行。它基於Speedtest.net的基礎架構來測量網絡的上/下行速率。安裝speedtest-cli很簡單——只需要下載其Python腳本文件。

 2.下載並授權

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

# chmod +rx speedtest.py

# sudo mv speedtest.py /usr/local/bin/speedtest-cli

# sudo chown root:root /usr/local/bin/speedtest-cli

 

使用speedtest-cli測試網速

使用speedtest-cli命令也很簡單，它不需要任何參數即可工作。

 

# speedtest-cli

輸入這個命令后，它會自動發現離你最近的Speedtest.net服務器（地理距離），然后打印出測試的網絡上/下行速率。

speedtest-cli --bytes以字節計算的方式來測試上下行速度
speedtest-cli --share將速度測試的結果生成一張圖片的連接，便於你分享
speedtest-cli --simple只顯示ping和上下行速度
speedtest-cli --list 列出speedtest.net所有的服務器距離你的物理距離，單位是千米（km）

optional arguments:
  -h, --help            show this help message and exit
  --no-download         Do not perform download test
  --no-upload           Do not perform upload test
  --bytes               Display values in bytes instead of bits. Does not
                        affect the image generated by --share, nor output from
                        --json or --csv
  --share               Generate and provide a URL to the speedtest.net share
                        results image, not displayed with --csv
  --simple              Suppress verbose output, only show basic information
  --csv                 Suppress verbose output, only show basic information
                        in CSV format. Speeds listed in bit/s and not affected
                        by --bytes
  --csv-delimiter CSV_DELIMITER
                        Single character delimiter to use in CSV output.
                        Default ","
  --csv-header          Print CSV headers
  --json                Suppress verbose output, only show basic information
                        in JSON format. Speeds listed in bit/s and not
                        affected by --bytes
  --list                Display a list of speedtest.net servers sorted by
                        distance
  --server SERVER       Specify a server ID to test against. Can be supplied
                        multiple times
  --exclude EXCLUDE     Exclude a server from selection. Can be supplied
                        multiple times
  --mini MINI           URL of the Speedtest Mini server
  --source SOURCE       Source IP address to bind to
  --timeout TIMEOUT     HTTP timeout in seconds. Default 10
  --secure              Use HTTPS instead of HTTP when communicating with
                        speedtest.net operated servers
  --no-pre-allocate     Do not pre allocate upload data. Pre allocation is
                        enabled by default to improve upload performance. To
                        support systems with insufficient memory, use this
                        option to avoid a MemoryError
  --version             Show the version number and exit
