参考 https://github.com/qinguoyi/TinyWebServer 和 《Linux高性能服务器编程》游双
C++实现http服务器，处理GET POST请求
- 线程池和**epoll(ET模式)**实现one reactor+多线程事件处理模型
- 使用状态机解析http请求
- 使用基于时间轮定时器处理非活动连接
- 实现同步/异步日志系统，记录服务器运行
- 添加前端代码，如登录、注册功能，请求canvas+js实现的小游戏、图片、视频等
- 拉取mysql镜像
sudo docker pull mysql - 运行mysql镜像
sudo docker run --name XXXX -p PORT:PORT -e MYSQL_ROOT_PASSWORD=XXXXXX -d mysql:latest - 开启容器
sudo docker start NAME - 进入容器
sudo docker exec -it NAME /bin/bash - mysql登录
mysql -u root -p
- 压测 使用Apachebench工具
ab -n 10000 -c 100 URL
测试10000个请求，100并发的情况，对应的服务器配置，在VBOX下6G内存+4核CPU，在本机运行测试程序，测试结果如下
Server Software:
Server Hostname: ****

Document Path: /
Document Length: 1131 bytes
Concurrency Level: 100
Time taken for tests: 119.681 seconds
Complete requests: 10000
Failed requests: 0
Total transferred: 11890000 bytes
HTML transferred: 11310000 bytes
Requests per second: 83.56 [#/sec] (mean)
Time per request: 1196.808 [ms] (mean)
Time per request: 11.968 [ms] (mean, across all concurrent requests)
Transfer rate: 97.02 [Kbytes/sec] received
