Mac自帶了Apache環境
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的參數說明
-n 需要執行的請求次數
-c 并發的數量
-t 等待返回的最長時間
-b TCP收發緩沖區的大小，單位（byte）
-p 使用post (同時需要定義-T參數)
-u 使用put (同時需要定義-T參數)
-T content-type, 例如application/x-www-form-urlencoded, 默認為text/plain
-w 把結果打印在html的表格里
-x 表格的屬性
-y tr行屬性
-z td列屬性
-C 設置cookie 例如Apach=1234
-H header行， 例如Accept-Encoding:gzip
-k 是否標示位HTTP Keep Alive
