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的默認根目錄。

Apache的安裝目錄在：/etc/apache2/，etc默認是隱藏的。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/  最后這個斜杠不能少

這個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   等待返回的最長時間

-b  TCP收發(fā)緩沖區(qū)的大小，單位（byte）

-p 使用post (同時需要定義-T參數(shù))

-u 使用put (同時需要定義-T參數(shù))

-T content-type, 例如application/x-www-form-urlencoded, 默認為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 是否標示位HTTP Keep Alive
