ab 是apache對 http伺服器進行壓力測試的工具,它可以測試出伺服器每秒可以處理多少請求。本文記錄mac版本安裝 ab 的步驟以及遇到的坑。

安裝
brew 安裝
- 因為筆者的作業系統是mac系統,所以需要先安裝brew。進入brew網站。執行下方命令
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
執行命令後報錯:
Failed to connect to raw.githubusercontent.com port 443: Connection refused
解決方案:
開啟 https://www.ipaddress.com/ 查詢 raw.githubusercontent.com 對應的 ip 地址。
新增ip到 /etc/hosts,新增以下配置:
185.199.108.133 raw.githubusercontent.com
185.199.109.133 raw.githubusercontent.com
185.199.110.133 raw.githubusercontent.com
185.199.111.133 raw.githubusercontent.com
再執行
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
執行成功後,使用brew安裝apr、apr-util和prce
brew install apr
brew install apr-util
brew inatll prce
apache ab安裝
解壓下載後壓縮包,進入 httpd-2.4.51 目錄。
執行以下命令:
./configure
make
make install
執行 ./configure 命令時報錯:
jeremy@jeremydeMacBook-Pro httpd-2.4.51 % ./configure
checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /usr/bin/grep
checking for egrep... /usr/bin/grep -E
checking build system type... x86_64-apple-darwin20.2.0
checking host system type... x86_64-apple-darwin20.2.0
checking target system type... x86_64-apple-darwin20.2.0
configure:
configure: Configuring Apache Portable Runtime library...
configure:
checking for APR... no
configure: error: APR not found. Please read the documentation.
APR not found 沒找到
./configure 改成
./configure --with-apr=/usr/local/opt/apr --with-apr-util=/usr/local/opt/apr-util --with-pcre=/usr/local/Cellar/pcre/8.45
其中 pcre 的路徑可能不同,需要在 /usr/local/Cellar/pcre 裡面確定路徑。
上述命令執行成功後,如果沒有報錯,表明安裝成功,執行ab
ab: wrong number of arguments
Usage: ab [options] [http[s]://]hostname[:port]/path
Options are:
-n requests Number of requests to perform
-c concurrency Number of multiple requests to make at a time
-t timelimit Seconds to max. to spend on benchmarking
This implies -n 50000
-s timeout Seconds to max. wait for each response
Default is 30 seconds
-b windowsize Size of TCP send/receive buffer, in bytes
-B address Address to bind to when making outgoing connections
-p postfile File containing data to POST. Remember also to set -T
-u putfile File containing data to PUT. Remember also to set -T
-T content-type Content-type header to use for POST/PUT data, eg.
'application/x-www-form-urlencoded'
Default is 'text/plain'
-v verbosity How much troubleshooting info to print
-w Print out results in HTML tables
-i Use HEAD instead of GET
出現以上介面,說明 ab 已經安裝成功。
執行 ab
主要引數
- -n 請求樹
- -c 併發數(訪問人數)
- -t 請求時間最大數
ab -n 1000 -c 100 http://www.baidu.com
表示請求baidu.com 使用100請求數,請求1000次。
總結
- 需要在配置brew和檢測configure上花了比較多的時間。
- 其餘的按照步驟即可。
