安裝brew 安裝因為筆者的操作系統是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)"執行命令后報錯:Failed to connect to raw.githubusercontent.com port 443: Connection refused解決方案:打開 https://www.ipaddress.com/ 查詢 raw.githubusercontent.com 對應的 ip 地址。

添加ip到 /etc/hosts,添加以下配置:

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

再執行
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"執行成功后，使用brew安裝apr、apr-util和prce
brew install aprbrew install apr-utilbrew inatll prceapache ab安裝解壓下載后壓縮包，進入 httpd-2.4.51 目錄。執行以下命令：
./configuremakemake install執行 ./configure 命令時報錯:

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 里面確定路徑。

上述命令執行成功后，如果沒有報錯，表明安裝成功，執行ab

出現以上界面，說明 ab 已經安裝成功。

總結【在線ddos免費測壓平臺 ab壓力測試命令】需要在配置brew和檢測configure上花了比較多的時間。其余的按照步驟即可。
