linux 下ab压力测试
1.ab的简介
ab是apachebench命令的缩写。
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
2.ab的原理
ab的原理：ab命令会创建多个并发访问线程，模拟多个访问者同时对某一URL地址进行访问。它的测试目标是基于URL的，因此，它既可以用来测试apache的负载压力，也可以测试nginx、lighthttp、tomcat、IIS等其它Web服务器的压力。
ab命令对发出负载的计算机要求很低，它既不会占用很高CPU，也不会占用很多内存。但却会给目标服务器造成巨大的负载，其原理类似CC攻击。自己测试使用也需要注意，否则一次上太多的负载。可能造成目标服务器资源耗完，严重时甚至导致死机。
3.ab的安装
yum -y install httpd-tools
apt-get install apache2-utils
6.ab的应用
ab的命令参数比较多，我们经常使用的是-c和-n参数。
ab -c 10 -n 100 http://www.myvick.cn/index.php ：同时处理100个请求并运行10次index.php
-c10表示并发用户数为10
-n100表示请求总数为100
[root@vic html]# ab -c 10 -n 100 http://www.myvick.cn/index.php

Server Software: nginx/1.13.6 #测试服务器的名字
Server Hostname: www.myvick.cn #请求的URL主机名
Server Port: 80 #web服务器监听的端口
Document Path: /index.php #请求的URL中的根绝对路径，通过该文件的后缀名，我们一般可以了解该请求的类型
Document Length: 799 bytes #HTTP响应数据的正文长度
Concurrency Level: 10 # 并发用户数，这是我们设置的参数之一
Time taken for tests: 0.668 seconds #所有这些请求被处理完成所花费的总时间 单位秒
Complete requests: 100 # 总请求数量，这是我们设置的参数之一
Failed requests: 0 # 表示失败的请求数量，这里的失败是指请求在连接服务器、发送数据等环节发生异常，以及无响应后超时的情况
Write errors: 0
Total transferred: 96200 bytes #所有请求的响应数据长度总和。包括每个HTTP响应数据的头信息和正文数据的长度
HTML transferred: 79900 bytes # 所有请求的响应数据中正文数据的总和，也就是减去了Total transferred中HTTP响应数据中的头信息的长度
Requests per second: 149.71 [#/sec] (mean) #吞吐率，计算公式：Complete requests/Time taken for tests 总请求数/处理完成这些请求数所花费的时间
Time per request: 66.797 [ms] (mean) # 用户平均请求等待时间，计算公式：Time token for tests/（Complete requests/Concurrency Level）。处理完成所有请求数所花费的时间/（总请求数/并发用户数）
Time per request: 6.680 [ms] (mean, across all concurrent requests) #服务器平均请求等待时间，计算公式：Time taken for tests/Complete requests，正好是吞吐率的倒数。也可以这么统计：Time per request/Concurrency Level
Transfer rate: 140.64 [Kbytes/sec] received #表示这些请求在单位时间内从服务器获取的数据长度，计算公式：Total trnasferred/ Time taken for tests，这个统计很好的说明服务器的处理能力达到极限时，其出口宽带的需求量。

#Percentage of requests served within a certain time（ms）这部分数据用于描述每个请求处理时间的分布情况，比如以上测试，80%的请求处理时间都不超过7ms，这个处理时间是指前面的Time per request，即对于单个用户而言，平均每个请求的处理时间
7 nginx和apache对比
nginx性能确实比apache性能高。nginx的吞吐量大于apache的，吞吐量越大越好
