一、安装：

wget http://download.joedog.org/siege/siege-4.0.4.tar.gz
tar -xzvf siege-4.0.4.tar.gz 
cd siege-4.0.4/
./configure --prefix="/usr/local/siege-404"
make && make install

ln -s /usr/local/siege-404/bin/siege.config /usr/local/bin/siege.config
ln -s /usr/local/siege-404/bin/siege.config /usr/bin/siege.config

ln -s /usr/local/siege-404/bin/siege /usr/local/bin/siege
ln -s /usr/local/siege-404/bin/siege /usr/bin/siege

二、常用命令介绍

2.1 Siege命令常用参数

-c 200 指定并发数200
-r 5 指定测试的次数5
-f urls.txt 制定url的文件
-i internet系统，随机发送url
-b 请求无需等待 delay=0
-t 5 持续测试5分钟,  如果需要精确掉秒 -t 5S
# -r和-t一般不同时使用

例子：

200个并发对http://www.baidu.com发送请求100次

siege -c 200 -r 100 http://www.baidu.com

随机选取urls.txt中列出所有的网址,200迸发 执行100次

siege -c 200 -r 100 -f urls.txt

随机选取urls.txt中列出所有的网址

siege -c 200 -r 100 -f urls.txt -i

#delay=0，更准确的压力测试，而不是功能测试

siege -c 200 -r 100 -f urls.txt -i -b

指定http请求头 文档类型

siege -H "Content-Type:application/json" -c 200 -r 100 -f urls.txt -i -b

在urls.txt 中PSOT类型的请求

http://www.baidu.com/index POST p1=v1&p2=v2 
注释：
POST参数之间用&符连接，K=V形式
如果url中含有空格和中文，要先进行url编码，否则siege发送的请求url不准确

输出结果介绍：
