Nginx学习(九) 使用ab压力测试Nginx
测试环境：VMWARE创建的虚拟机
2个CPU 3.7G内存
1、安装httpd
yum install httpd
2、模拟1000个用户50000次请求Nginx首页
cd /usr/bin
./ab -c 1000 -n 50000 localhost:88/index.html
结果：
Server Software: nginx/1.17.8
Server Hostname: localhost
Server Port: 88
Document Path: /index.html
Document Length: 612 bytes
Concurrency Level: 1000
Time taken for tests: 4.623 seconds
Complete requests: 50000
Failed requests: 0
Write errors: 0
Total transferred: 42250000 bytes
HTML transferred: 30600000 bytes
Requests per second: 10814.71 [#/sec] (mean)
Time per request: 92.467 [ms] (mean)
Time per request: 0.092 [ms] (mean, across all concurrent requests)
Transfer rate: 8924.25 [Kbytes/sec] received
Connection Times (ms)
min mean[+/-sd] median max
Connect: 0 40 81.9 28 1060
Processing: 13 50 22.0 42 136
Waiting: 4 39 19.0 33 131
Total: 43 90 87.9 68 1159
Percentage of the requests served within a certain time (ms)
50% 68
66% 81
75% 97
80% 114
90% 138
95% 158
98% 173
99% 178
100% 1159 (longest request)
3、安装nginx统计模块with-http_stub_status_module
进入nginx解压的目录
./configure --prefix=/usr/local/nginx --with-http_stub_status_module
make && make install
4、开启统计模块
gedit /usr/local/nginx/conf/nginx.conf
添加
location /status {
stub_status on;
access_log off;
allow 192.168.1.72;
deny all;
}
/usr/local/nginx/sbin/nginx -s reload
访问http://192.168.1.72:88/status
5、再次使用ab压测
重复第2步
压测过程中可以查看nginx统计
