红包秒杀系统:模拟红包秒杀时的高并发场景,学习并实现业界成熟的秒杀架构。
1.安装并启动rocketmq
http://rocketmq.apache.org/docs/quick-start/
nohup sh bin/mqnamesrv &
nohup sh bin/mqbroker -n localhost:9876 &
2.安装并启动reids
./src/redis-server
3.启动本项目
运行RedEnvelopeApplication main方法
4.创建红包
POST http://localhost:8080/red-envelope/create
请求body:
{
"user": "lewiszlw",
"type": "ORDINARY",
"amount": 10000,

}
5.抢红包
GET http://localhost:8080/red-envelope/grab?envelopeId=1&grabber=lewis
注:envelopeId 为红包id,grabber 为抢红包者
6.验证结果(对账)
GET http://localhost:8080/red-envelope/verify?envelopeIds=3,4,5,6
1.安装locust
https://docs.locust.io/en/latest/index.html
pip3 install locustio
2.修改locustfile.py
修改locustfile.py中的ENVELOPE_ID为创建好的红包id
3.在项目目录下执行命令
locust --host=http://127.0.0.1:8080
4.打开Locust web界面,输入指标开始压测
ps.可以开多个slave来提高RPS (Requests per second)
