Linux下siege的安装和实战

Posted 2020-10-26 magicianyin

一. siege的安装

1. 下载最新版本的siege

   wget http://download.joedog.org/siege/siege-latest.tar.gz

2. 解压并进入siege路径

   tar -zxvf siege-latest.tar.gz
   cd siege-*/

3. 如果没有安装编译工具，请先安装

   sudo apt-get install build-essential

4. 编译安装

   ./configure
   make
   sudo make install

5. 创建配置文件

   siege.config

6. 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

1. 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

2. 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

   [email protected]:~/test$ siege -c 5 -t 1M -f url.txt
   Lifting the server siege...      done. 
   Transactions:                345 hits

   Elapsed time:              59.73 secs
   Data transferred:           1.88 MB
   Response time:              0.36 secs
   Transaction rate:           5.78 trans/sec
   Throughput:             0.03 MB/sec
   Concurrency:                2.10
   Successful transactions:         345
   Failed transactions:               0
   Longest transaction:           27.16
   Shortest transaction:           0.21

3. 需求2:保存siege日志
   将log保存在result.csv,并且打开result.csv

   [email protected]:~/test$ siege -c 5 -t 1M -f url.txt --log=result.csv
   [email protected]:~/test$ more result.csv 
     Date & Time,  Trans,  Elap Time,  Data Trans,  Resp Time,  Trans Rate,  Throughput,  Concurrent,    OKAY,   Failed
   2018-02-07 04:10:10,    160,      59.30,           0,       0.35,        2.70,        0.00,        0.95,     160,       4

4. 需求3:压测时候启用gzip压缩
   Accept-Encoding设置成gzip,并将log保存在result_gzip.csv,并且打开result_gzip.csv

   [email protected]:~/test$ siege -c 5 -t 1M -f url.txt -H "Accept-Encoding:gzip" --log=result_gzip.csv
   [email protected]:~/test$ more result_gzip.csv 
     Date & Time,  Trans,  Elap Time,  Data Trans,  Resp Time,  Trans Rate,  Throughput,  Concurrent,    OKAY,   Failed
   2018-02-07 04:22:44,    197,      59.83,           1,       0.35,        3.29,        0.02,        1.14,     197,       3

5. 需求4:对移动站点进行压测
   将user-agent设置成iPhone发送给服务器

   [email protected]:~/test$ siege -c 1 -r 1 -A "Apple-iPhone5C2/1001.525" http://www.baidu.com
