使用Apache ab進(jìn)行http性能測試
Mac自帶了Apache環(huán)境
打開“終端(terminal)”,輸入 sudo apachectl -v,(可能需要輸入機(jī)器秘密)。如下顯示Apache的版本
接著輸入 sudo apachectl start,這樣Apache就啟動了。打開Safari瀏覽器地址欄輸入 “http://localhost”,可以看到內(nèi)容為“It works!”的頁面。其位于“/Library(資源庫)/WebServer/Documents/”下,這就是Apache的默認(rèn)根目錄。
Apache的安裝目錄在:/etc/apache2/,etc默認(rèn)是隱藏的。有三種方式查看:
1、dock下右鍵Finder,選擇"前往文件夾",輸入"/etc"
2、在finder下----》前往---》前往文件夾,然后輸入/etc
3、可以在terminal 輸入 "open /etc"
windows可以去http://httpd.apache.org/download.cgi下載,或者從命令行安裝
1. 安裝apache
sudo port install apache2
啟動apache: sudo apachectl start
2. brew install pcre
3. wget http://ftp.yz.yamagata-u.ac.jp/pub/network/apache//httpd/httpd-2.4.4.tar.bz2
(1)解壓
(2) ./configure
(3) make && make install
(4) sudo cp support/ab /usr/sbin
4. ab -n 1000 -c 10 http://localhost:3000/ 最后這個(gè)斜杠不能少
這個(gè)ab -n1000 -c10 http://localhost:3000/命令,在window系統(tǒng)下,需要先用cd命令定位到你的apache安裝目錄的bin文件夾。。。
ab的參數(shù)說明
-n 需要執(zhí)行的請求次數(shù)
-c 并發(fā)的數(shù)量
-t 等待返回的最長時(shí)間
-b TCP收發(fā)緩沖區(qū)的大小,單位(byte)
-p 使用post (同時(shí)需要定義-T參數(shù))
-u 使用put (同時(shí)需要定義-T參數(shù))
-T content-type, 例如application/x-www-form-urlencoded, 默認(rèn)為text/plain
-w 把結(jié)果打印在html的表格里
-x 表格的屬性
-y tr行屬性
-z td列屬性
-C 設(shè)置cookie 例如Apach=1234
-H header行, 例如Accept-Encoding:gzip
-k 是否標(biāo)示位HTTP Keep Alive
