tar -zxvf siege-latest.tar.gz
cd siege-*/
- 如果没有安装编译工具,请先安装
sudo apt-get install build-essential
- 编译安装
./configure
make
sudo make install
- 创建配置文件
siege.config
- 修改配置文件
打开~/.siege/siege.conf文件,修改logfile选项
logfile = $(HOME)/siege.log
打开siege -h看是否安装成功,打开siege -h可以看到siege的有关参数
二. siege实战
- siege常见参数
- -c 指定并发数
- -r 指定重复次数
- -d 指定请求的延迟时间,注意每个请求间随机延迟
- -f 指定url列表,可以一次给多个地址加压
- -t 指定用例执行时间,比如-t 10s -t 1M(H)之类
- -g 获取请求的headers信息并打印出来,debug专用
- -H 指定请求的headers信息
- -l或--log=[File] 指定测试结果的路径
- 需求1:使用siege对多个页面进行加压
使用siege对多个页面加压,并且并发数是5,运行1分钟
页面URL:http://ur.tencent.com/categories/7
http://ur.tencent.com/categories/7/?page=2
http://ur.tencent.com/categories/7/?page=3
在虚拟机ubuntu访问上面三条连接,并发数是5,持续运行1分钟
