Mac自带了Apache环境
打开“终端(terminal)”,输入 sudo apachectl -v,(可能需要输入机器秘密)。如下显示Apache的版本
接着输入 sudo apachectl start,这样Apache就启动了。打开Safari浏览器地址栏输入 “http://localhost”,可以看到内容为“It works!”的页面。其位于“/Library(资源库)/WebServer/Documents/”下,这就是Apache的默认根目录。
Apache的安装目录在:/etc/apache2/,etc默认是隐藏的。有三种方式查看:
1、dock下右键Finder,选择"前往文件夹",输入"/etc"
2、在finder下----》前往---》前往文件夹,然后输入/etc
3、可以在terminal 输入 "open /etc"
windows可以去http://httpd.apache.org/download.cgi下载,或者从命令行安装
1. 安装apache
sudo port install apache2
启动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)解压
(2) ./configure
(3) make && make install
(4) sudo cp support/ab /usr/sbin
4. ab -n 1000 -c 10 http://localhost:3000/ 最后这个斜杠不能少
这个ab -n1000 -c10 http://localhost:3000/命令,在window系统下,需要先用cd命令定位到你的apache安装目录的bin文件夹。。。
ab的参数说明
-n 需要执行的请求次数
-c 并发的数量
-t 等待返回的最长时间
-b TCP收发缓冲区的大小,单位(byte)
-p 使用post (同时需要定义-T参数)
-u 使用put (同时需要定义-T参数)
-T content-type, 例如application/x-www-form-urlencoded, 默认为text/plain
-w 把结果打印在html的表格里
-x 表格的属性
-y tr行属性
-z td列属性
-C 设置cookie 例如Apach=1234
-H header行, 例如Accept-Encoding:gzip
-k 是否标示位HTTP Keep Alive
