1.安装
安装包下载地址：
将 httpd-2.2.29.tar.gz 解压到目录 /apps/install/httpd-2.2.29 ，这是我放置的位置
cd /apps/install/httpd-2.2.29
./configure
make
make install
ok ,没有 error 就表示安装成功了，上面我并没有改变他的编译目录，默认的编译目录在
/usr/local/apache2/bin
如果找不到了，搜索呗
find . -name httpd
2.测试
进入 /usr/local/apache2/bin
cd /usr/local/apache2/bin
./ab -n 300 -c 300 http://www.baidu.com/
执行 300次，每次并发 300个请求 www.baidu.com
./ab -n 3000 -c 3000 http://www.test.com/
其中-n代表每次并发量，-c代表总共发送的数量
3.测试结果说明
