启动Sentinel Dashboard，默认是8080端口，这里指定8084端口
[root@elastic1 ~]# java -jar /app/sentinel-dashboard-1.6.2.jar --server.port=8084
或者
[root@elastic1 app]# java -jar sentinel-dashboard-1.6.2.jar --server.port=8084

curl localhost:8085/hello
配置限流规则
簇点链路–>流控
阈值类型：默认寻找QPS即可
单机阈值：输入2，表示/hello接口的限流策略是每秒最多允许2个请求进入
验证限流
这里尝试快速访问curl localhost:8085/hello，多次尝试后，出现如下效果。
