### 前情提要 : 本文基于 [SpringCloud H系列 alibaba 2.1.1 (一) sentinel 限流熔断(基于dubbo)][SpringCloud H_ alibaba 2.1.1 _ sentinel _dubbo] ###

# 1.下载sentinel-dashboard #

地址 : [sentinel-dashboard 下载地址][sentinel-dashboard]

版本使用 1.7.0

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQ2MTI4MQ_size_16_color_FFFFFF_t_70][]

下载完成后 本地启动 sentinel-dashboard-1.7.0.jar

java -jar sentinel-dashboard-1.7.0.jar

*  \-Dserver.port 指定服务端口
 *  \-Dcsp.sentinel.dashboard.server 指定对位暴露地址
 *  \-Dsentinel.dashboard.auth.username 设置用户名
 *  \-Dsentinel.dashboard.auth.password 设置密码
 *  \-Dproject.name 设置应用项目名
 *  \-Dserver.servlet.session.timeout 设置session超时时间

默认端口8080 默认账号密码 sentinel

访问 localhost:8080 登录控制台

由于目前没有服务注册 所以控制台上并没有实例

# 2.改造dubbo消费端 集成sentinel控制台 #

在 alibaba-sentinel-dubbo-client 项目中增加依赖

<dependency>
                <groupId>com.alibaba.csp</groupId>
                <artifactId>sentinel-transport-simple-http</artifactId>
            </dependency>

在nacos 中 application-sentinel-dubbo-client.yml配置文件中

增加以下配置

spring:
      cloud:
        # sentinel 控制台地址 注册服务
        sentinel:
          transport:
            dashboard: 127.0.0.1:8080

启动消费端服务 查看sentinel控制台

注册成功

查看流控规则

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQ2MTI4MQ_size_16_color_FFFFFF_t_70 3][]

这里是我们使用代码配置的规则 QPS大于1熔断

# 3.测试控制台功能 #

修改阀值为5

疯狂访问 localhost:8002/test?name=Lion Li

查看实时监控

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQ2MTI4MQ_size_16_color_FFFFFF_t_70 4][]

通过QPS最高为5 到达5后限流熔断

控制台集成成功

sentinel 控制台功能非常之多 感兴趣的可以查看官方文档具体学习 这里我就不细说了

项目已上传到gitee
