Post:
ab -p post_loc.txt -T application/json -H 'Authorization: Token abcd1234' -c 10 -n 2000 http://example.com/api/v1/locations/
Get:
ab -c 10 -n 1000 localhost/test
Usage: ab [options] [http[s]://]hostname[:port]/path
Options are:
-n requests Number of requests to perform
-c concurrency Number of multiple requests to make at a time

-B address Address to bind to when making outgoing connections
-p postfile File containing data to POST. Remember also to set -T
-u putfile File containing data to PUT. Remember also to set -T
-T content-type Content-type header to use for POST/PUT data, eg.
'application/x-www-form-urlencoded'
Default is 'text/plain'
-v verbosity How much troubleshooting info to print
-w Print out results in HTML tables
-i Use HEAD instead of GET
-x attributes String to insert as table attributes
-y attributes String to insert as tr attributes
-z attributes String to insert as td or th attributes
-C attribute Add cookie, eg. 'Apache=1234'. (repeatable)

Inserted after all normal header lines. (repeatable)
-A attribute Add Basic WWW Authentication, the attributes
are a colon separated username and password.
-P attribute Add Basic Proxy Authentication, the attributes
are a colon separated username and password.
-X proxy:port Proxyserver and port number to use
-V Print version number and exit

-f protocol Specify SSL/TLS protocol
(SSL3, TLS1, TLS1.1, TLS1.2 or ALL)
ab是apache自带的压力测试工具。ab非常实用,它不仅可以对apache服务器进行网站访问压力测试,也可以对或其它类型的服务器进行压力测试。比如nginx、tomcat、IIS等。
一、Apache下载
Windows下载地址: http://www.apachehaus.com/cgi-bin/download.plx

根据系统版本选择
下载后,解压到C盘Apache 文件夹。
二、配置
修改Apache 端口:
如果是windows部署,多数情况下80端口已经被iis占用了,这时候需要修改conf/httpd.conf 找到listen 80 改为你要设置的端口,如: 8090。
三、Apache安装
以管理员身份运行cmd,命令行进入到Apache的bin目录,输入 httpd -k install 完成安装。
四、开始测试
在apache的bin目录下,cmd中输入:ab -n 1000 -c 1000 http://so.com/index
其中,-n 表示请求数,-c 表示并发数,index 为path,这是必要的,表示指定测试地址,不指定可能会报”ab: invalid url” 错误,可以实际测试一下。
其返回的结果集是有很多内容,我们选择关键的几个看看就大概知道我们的模块性能了
我比较关心的几个结果:
Concurrency Level: 1000
Time taken for tests: 1.190 seconds //处理1000个并发请求总共花了1.19秒
Complete requests: 1000 //完成处理的请求量
Failed requests: 0 //请求失败数
Write errors: 0
Non-2xx responses: 1000
Total transferred: 164000 bytes //总共传输了多少流量
HTML transferred: 0 bytes
Requests per second: 840.58 [#/sec] (mean) //平均一个请求花840.58毫秒 大家最关心的指标之一,相当于 LR 中的每秒事务数,后面括号中的 mean 表示这是一个平均值
Time per request: 1189.651 [ms] (mean) //大家最关心的指标之二,相当于 LR 中的平均事务响应时间,后面括号中的 mean 表示这是一个平均值
Time per request: 1.190 [ms] (mean, across all concurrent requests) //每个请求实际运行时间的平均值 ms是毫秒
Transfer rate: 134.62 [Kbytes/sec] received //传输速率 可以帮助排除是否存在网络流量过大导致响应时间延长的问题
