## PHP ab 压力并发测试 ##

PHP接口并发测试的方法

系统：Ubuntu18.04

安装ab测试工具  
如果没安装，输入ab -v，根据提示安装

\-n:请求次数  
\-c:并发数

Server Software: nginx \#被测试服务器软件名称  
Server Hostname: local.meiricp.admin.cn \#被测试域名  
Server Port: 80 \#端口

Document Path: /goods/goods/list \#请求的URL中的根绝对路径  
Document Length: 97 bytes \#页面的大小

Concurrency Level: 100 \#并发数  
Time taken for tests: 6.703 seconds \#整个测试消耗  
Complete requests: 1000 \#总共完成的请求数  
Failed requests: 0 \#请求失败次数  
Total transferred: 621000 bytes \#测试过程中产生的网络传输总量  
HTML transferred: 97000 bytes \#测试过程中产生的HTML传输量  
Requests per second: 149.20 \[\#/sec\] (mean) \#表示服务器吞吐量，每秒事务数，括号中的 mean 表示这是一个平均值  
Time per request: 670.261 \[ms\] (mean) \#表示用户请求的平均响应时间，后面括号中的mean表示这是一个平均值  
Time per request: 6.703 \[ms\] (mean, across all concurrent requests) \#表示服务器请求平均处理时间，即实际运行时间的平均值  
Transfer rate: 90.48 \[Kbytes/sec\] received \#表示这些请求在单位时间内从服务器获取的数据长度，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

Connection Times (ms)  
min mean\[+/-sd\] median max \#min最小值、mean平均值、\[+/-sd\]方差、median中位数、maxz最大值  
Connect: 0 2 5.1 0 18 \#socket链路建立消耗
