安装：
wget http://download.joedog.org/siege/siege-3.0.8.tar.gz
tar xzvf siege-3.0.8.tar.gz
cd siege-3.0.8
./configure
make && make install
[root@zhuiqiuqiji www]# find / -name 'siege'

/usr/local/bin/siege
/usr/local/bin/siege -h
准备测试url 或者url列表文件
压测：
20个用户（每次并发量，注意不是每秒并发量） 重复10次 共产生 20 * 10 = 200个请求 如下：
案例1：
[root@zhuiqiuqiji www]# /home/yeqing/siege-3.0.8/src/siege php ./test.php -b -c20 -r10
** SIEGE 3.0.8

说明：-c是并发量，-r是重复次数。url_list.txt就是一个文本文件，每行都是一个url，它会从里面随机访问的。
案例2：
