## README

### 1.简介

原始的Sentinel-Dashboard的配置默认放在内存中的，并通过openapi通知应用。当Sentinel-Dashboard或者应用重启时，总是会丢失一部分数据，这是不友好的。

给Sentinel-Dashboard添加动态数据源，就可以解决这部分问题，详情请参考[官方文档](https://github.com/alibaba/Sentinel/wiki/%E5%8A%A8%E6%80%81%E8%A7%84%E5%88%99%E6%89%A9)。

### 2.主要功能

- Nacos作为Sentinel-Dashboard的数据源
- Apollo作为Sentinel-Dashboard的数据源

#### 2.1 Nacos-Sentinel-Dashboard

- 启动服务端

```bash
java -Dserver.port=8080 \
    -Dproject.name=sentinel-dashboard \
    -Dcsp.sentinel.dashboard.server=localhost:8080 \
    -Dsentinel.datasource.mode=nacos \
    -Dsentinel.dashboard.datasource.nacos.serverAddr=127.0.0.1:8848 \
    -Dsentinel.dashboard.datasource.nacos.namespace=namespace \
    -Dsentinel.dashboard.datasource.nacos.username=nacos \
    -Dsentinel.dashboard.datasource.nacos.password=nacos \
    -jar sentinel-dashboard.jar
```

- 创建Nacos配置文件

在Nacos指定命名空间中按需创建sentinel-dashboard的配置文件

- 1. ${application}-sentinel-flow
- 2. ${application}-sentinel-param-flow
- 3. ${application}-sentinel-system
- 4. ${application}-sentinel-degrade
- 5. ${application}-sentinel-authority
- 6. ${application}-sentinel-gateway-flow
- 7. ${application}-sentinel-gateway-api

- 客户端配置Nacos监听

在sentinel-dashboard中修改配置以后，会同步到Nacos中，再由Nacos实时通知到应用端，应用端收到数据后，更新规则。


#### 2.2 Nacos-Sentinel-Dashboard


- 启动服务端

```bash
java -Dserver.port=8080 \
    -Dproject.name=sentinel-dashboard \
    -Dcsp.sentinel.dashboard.server=localhost:8080 \
    -Dsentinel.datasource.mode=apollo \
    -Dsentinel.dashboard.datasource.apollo.portalUrl=http://dev.apollo.kancy.com \
    -Dsentinel.dashboard.datasource.apollo.token=423670ef5234331eaebae5a1ed9c379c00f3cef6 \
    -Dsentinel.dashboard.datasource.apollo.appId=sentinel-dashboard \
    -Dsentinel.dashboard.datasource.apollo.env=dev \
    -Dsentinel.dashboard.datasource.apollo.clusterName=default \
    -jar sentinel-dashboard.jar
```

- 初始化Apollo

    - 创建一个项目，默认appId为sentinel-dashboard
    - 根据应用名创建命名空间：${application}.properties (应用引用)

- 客户端配置Apollo监听

在sentinel-dashboard中修改配置以后，会同步到Apollo中，再由Apollo实时通知到应用端，应用端收到数据后，更新规则。
