1.按照下图完成Apache的下载及安装( http://httpd.apache.org/ )
下载好解压到指定目录下。
2.使用
命令行下进入Apache下的bin目录，输入：http -k install，将Apache安装成windows后台服务。
E:\Apache\Apache24\bin>httpd -k install
Installing the 'Apache2.4' service
The 'Apache2.4' service is successfully installed.
Testing httpd.conf....
Errors reported here must be corrected before the service can be started.
httpd: Syntax error on line 39 of E:/Apache/Apache24/conf/httpd.conf: ServerRoot must be a valid directory
这时安装时失败的，错误信息告诉你应该以管理员的身份运行，这个时候我们找到C:\Windows\System32下的cmd.exe右键单击选择“以管理员身份运行”
接下来还要做一件事，我们打开E:\Apache\Apache24\conf下的httpd.conf，将其中的serverroot指向你的安装位置：
Define SRVROOT "E:/Apache/Apache24" ServerRoot "${SRVROOT}"
然后执行命令：httpd -k uninstall，并再次执行安装命令httpd -k install
E:\Apache\Apache24\bin>httpd -k uninstall
Removing the 'Apache2.4' service
The 'Apache2.4' service has been removed successfully.
E:\Apache\Apache24\bin>httpd -k install
Installing the 'Apache2.4' service
The 'Apache2.4' service is successfully installed.
Testing httpd.conf....
Errors reported here must be corrected before the service can be started.
表示安装成功，随后执行
E:\Apache\Apache24\bin>httpd -k start
浏览器中输入http://localhost测试是否成功。
3.ab测试
Apache Benchmark简称ab，是Apache自带的用http server测试工具
E:\Apache\Apache24\bin>ab -n1000 -c10 http://cmall.ishaohuo.cn/
This is ApacheBench, Version 2.3 <$Revision: 1807734 $>

上述的表示每次并发10个请求，总共请求10000次，从结果中我们可以得知服务器的相关信息，time taken for tests整个测试耗时，complete request总共完成的请求数量，total transferred测试过程中产生的网络传输总量，request per second表示服务器吞吐量，Percentage of the requests served within acertain time (ms)整个场景中所有请求的响应情况。在场景中每个请求都有一个响应时间，其中50％的用户响应时间小于94毫秒，80％的用户响应时间小于102毫秒，最大的响应时间小于156 毫秒
Ab命令参数注释：
-n #指定在测试会话中所执行的请求个数。默认时，仅执行一个请求。
-c #指定一次产生的请求个数。默认是一次一个。
-t #测试所进行的最大秒数。其内部隐含值是-n 50000。它可以使对服务器的测试限制在一个固定的总时间以内。默认时，没有时间限制。
-p #包含了需要POST的数据的文件.
-T #POST数据所使用的Content-type头信息。
-v #设置显示信息的详细程度 - 4或更大值会显示头信息， 3或更大值可以显示响应代码(404, 200等), 2或更大值可以显示警告和其他信息。 -V 显示版本号并退出。
-w #以HTML表的格式输出结果。默认时，它是白色背景的两列宽度的一张表。
-I #执行HEAD请求，而不是GET。
