mac安装Apache ab压力测试工具

因为ab是Apache自带的压测工具，因此安装好apache的httpd便可

第一步： 安装apache

AT7730:~ yangchuanhuan$ sudo port install apache2

....

60 from https://packages.macports.org/apache2

--->  Installing apache2 @2.2.31_2+preforkmpm

--->  Activating apache2 @2.2.31_2+preforkmpm

--->  Cleaning apache2

--->  Updating database of binaries

--->  Scanning binaries for linking errors               

--->  No broken files found.

说明安装成功

第二步： 下载并安装httpd

首先下载httpd，打开网址：http://ftp.yz.yamagata-u.ac.jp/pub/network/apache/httpd/

能够看到Apache httpd的系统版本信息，

找到最新版本：

 httpd-2.2.32.tar.bz2       2017-01-13 03:38  5.5M  HTTP Server project

下载到本地，而后进入到下载压缩包所在的目录：

AT7730:~ yangchuanhuan$ cd /Users/yangchuanhuan/Downloads/

AT7730:Downloads yangchuanhuan$ tar -zxvf httpd-2.2.32.tar.bz2

解压完成后，进入解压后的目录

AT7730:Downloads yangchuanhuan$ cd httpd-2.2.32

AT7730:httpd-2.2.32 yangchuanhuan$ ./configure 

若是出现以下错误信息

Making install in prefork

Making install in modules

Making install in aaa

mkdir /usr/local/apache2

mkdir: /usr/local/apache2: Permission denied

mkdir /usr/local/apache2/modules

mkdir: /usr/local/apache2: No such file or directory

make[3]: *** [install-modules-yes] Error 1

make[2]: *** [install-recursive] Error 1

make[1]: *** [install-recursive] Error 1

make: *** [install-recursive] Error 1

说明没有权限建立apache2和apache2/modules文件夹

手动建立这两个文件夹，并将apache2文件夹全部者修改成当前用户

AT7730:local yangchuanhuan$ sudo mkdir apache2

AT7730:local yangchuanhuan$ cd apache2/

AT7730:apache2 yangchuanhuan$ mkdir modules

AT7730:local yangchuanhuan$ sudo chown -R yangchuanhuan apache2

而后再执行

AT7730:httpd-2.2.32 yangchuanhuan$ ./configure 

AT7730:httpd-2.2.32 yangchuanhuan$ sudo make && make install

至此httpd已经安装成功了，

AT7730:httpd-2.2.32 yangchuanhuan$ cd support/

AT7730:support yangchuanhuan$ ab

ab: wrong number of arguments

Usage: ab [options] [http[s]://]hostname[:port]/path

Options are:

    -n requests     Number of requests to perform

    -c concurrency  Number of multiple requests to make at a time

    -t timelimit    Seconds to max. to spend on benchmarking

                    This implies -n 50000

......

说明ab已经能够正常使用了
