  • 使用Apache ab进行http性能测试

    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
