get、post請(qǐng)求使用ab工具如何做并發(fā)測(cè)試

最近確實(shí)也有些忙，原來都是利用周末的時(shí)間寫東西，現(xiàn)在周末的時(shí)間被占滿，照顧小孩。只能忙中找空，寫點(diǎn)東西。

最近正好使用ab性能測(cè)試工具測(cè)了一個(gè)項(xiàng)目，主要用來做并發(fā)測(cè)試，需求是控制水軍用戶的并發(fā)數(shù)，通過nginx配置控制并發(fā)量（針對(duì)異常ip--雙ip），所以為了能夠快速上線，就選擇了ab工具。覺得ab工具多多少少還是可以快速的運(yùn)用到工作當(dāng)中，所以有必要寫出來分享給需要的同行。主要介紹下使用ab工具并發(fā)發(fā)送get和post請(qǐng)求，比如日常工具中做并發(fā)測(cè)試可以使用（針對(duì)活動(dòng)等相關(guān)庫存的并發(fā)測(cè)試）

linux下安裝ab性能測(cè)試工具

yum -y install httpd-tools

安裝完成后，執(zhí)行：

ab -H 'X-Forwarded-For:2.2.2.2' -n 100 -c 30 http://m.1768.com/?act=index&st=login

備注：

2.2.2.2為模擬的ip

查看nginx訪問日志：

m.1768.com 21.58.201.31 - - [18/Sep/2017:18:57:43 +0800] "GET /?act=index&st=login HTTP/1.0" 200 266 "-" "ApacheBench/2.3" 2.2.2.2,47.94.13.33

執(zhí)行結(jié)果如下：

至于用作性能分析建議還是使用LR，有興趣也可以對(duì)性能結(jié)果進(jìn)行分析。
