ab 是apache对 http服务器进行压力测试的工具，它能够测试出服务器每秒能够解决多少申请。本文记录mac版本装置 ab 的步骤以及遇到的坑。

下载

进入 apache ab官网 下载页面。

装置

brew 装置

  • 因为笔者的操作系统是mac零碎，所以须要先装置brew。进入brew网站。执行下方命令

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

    执行命令后报错:
    Failed to connect to raw.githubusercontent.com port 443: Connection refused
    解决方案:
    关上 https://www.ipaddress.com/ 查问 raw.githubusercontent.com 对应的 ip 地址。

增加ip到 /etc/hosts,增加以下配置:

185.199.108.133 raw.githubusercontent.com185.199.109.133 raw.githubusercontent.com185.199.110.133 raw.githubusercontent.com185.199.111.133 raw.githubusercontent.com

再执行

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

执行胜利后，应用brew装置apr、apr-util和prce

brew install aprbrew install apr-utilbrew inatll prce

apache ab装置

解压下载后压缩包，进入 httpd-2.4.51 目录。
执行以下命令：

./configuremakemake install

执行 ./configure 命令时报错:

jeremy@jeremydeMacBook-Pro httpd-2.4.51 % ./configurechecking for chosen layout... Apachechecking for working mkdir -p... yeschecking for grep that handles long lines and -e... /usr/bin/grepchecking for egrep... /usr/bin/grep -Echecking build system type... x86_64-apple-darwin20.2.0checking host system type... x86_64-apple-darwin20.2.0checking target system type... x86_64-apple-darwin20.2.0configure:configure: Configuring Apache Portable Runtime library...configure:checking for APR... noconfigure: error: APR not found.  Please read the documentation.

APR not found 没找到
./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 的门路可能不同，须要在 /usr/local/Cellar/pcre 外面确定门路。

上述命令执行胜利后，如果没有报错，表明装置胜利，执行ab

ab: wrong number of argumentsUsage: ab [options] [http[s]://]hostname[:port]/pathOptions 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

呈现以上界面，阐明 ab 曾经装置胜利。

运行 ab

主要参数

  • -n 申请树
  • -c 并发数（拜访人数）

  • -t 申请工夫最大数

    ab -n 1000 -c 100 http://www.baidu.com
    示意申请baidu.com 应用100申请数，申请1000次。

总结

  • 须要在配置brew和检测configure上花了比拟多的工夫。
  • 其余的依照步骤即可。
