http压力测试工具及使用说明
说明:介绍几款简单、易使用http压测工具,便于研发同学,压测服务,明确服务临界值,寻找服务瓶颈点。
压测时候可重点以下指标,关注并发用户数、TPS(每秒事务数量)、RT(事务响应时间)、事物失败率、CPU(不要超过70%)、LOAD(4核以下服务,不要超过2)
http_load
以并行复用的方式运行,以测试web服务器的吞吐量与负载。不同于大多数压力测试工具,它是单进程,所以一般不会把客户机搞死,也可以测试https类网站的请求。
支持多个url。
wget http://acme.com/software/http_load/http_load-14aug2014.tar.gz
tar zxvf http_load-14aug2014.tar.gzln -s http_load-14aug2014 http_loadcd http_loadmake && make install➜ /Users/yxy/data/soft/http_load >http_load --helpusage: http_load [-checksum] [-throttle] [-proxy host:port] [-verbose] [-timeout secs] [-sip sip_file] -parallel N | -rate N [-jitter]

One start specifier, either -parallel or -rate, is required.One end specifier, either -fetches or -seconds, is required.参数简单说明-parallel 简写-p:并发的用户数-rate 简写-r:每秒访问次数-fetches 简写-f:总计访问次数-seconds 简写-s:持续访问时间url_file 压测url(文件形式,需要访问的url,支持多个,每行一个) |

Apache Bench(Apache自带服务器压力测试工具)
➜ /Users/yxy >ab -c 10 -n 50 http://192.168.100.152:18800/casefolder-social/question/detail?shareUID=40d0c000-09b6-416c-b626-b9ce61399d07
-- -n 表示:每次请求数,默认不能超过1024个,-c表示:1个请求的并发连接数,默认最大不能超过50000。
-- 模拟50个并发连接每次以100个请求数来测试网站的Web性能

webbench
使用方式和http_load相似,指标较为简单
webbench是Linux下的一个网站压力测试工具,最多可以模拟3万个并发连接去测试网站的负载能力。
下载地址:http://soft.vpser.net/test/webbench/webbench-1.5.tar.gz
安装非常简单
#tar zxvf webbench-1.5.tar.gz
#cd webbench-1.5
#make && make install |
会在当前目录生成webbench可执行文件,直接可以使用了
用法:webbench -c 并发数 -t 运行测试时间 URL
例如:
/Users/yxy/data/soft/webbench >webbench -c 10 -t 30 http://192.168.100.152:18800/casefolder-social/question/detail\?shareUID\=40d0c000-09b6-416c-b626-b9ce61399d07
