Sentinel1.8.4 persistent Nacos configuration

Premise

sentinel Be responsible for flow control fuse configuration in the project , But the previous configuration data will be lost after restart , Because the configuration is stored in memory by default , You need to manually configure the persistence policy

Operation steps

step 1

download sentinel Source code , Links are as follows

https://github.com/alibaba/Sentinel
sentinel-dashboard Catalog ：
https://github.com/alibaba/Sentinel/tree/master/sentinel-dashboard

step 2

Other module dependencies can be removed , Only keep sentinel-dashboard

step 3, Modify the corresponding persistence configuration

1. application.properties Add the configuration

# nacos Persistent configuration server.port=8858 nacos.address=20.21.1.158:8848 nacos.namespace=appName-openapi-sentinel

2. test Under module nacos Reference configuration ： Including off the shelf flow Persistence

3. Same configuration , add to degrade Fuse configuration ,

4. Modify current limit , Blown controller, Let the rules change nacos Persistence

5. With FlowControllerV1 For example ： introduce nacos Persistent services for

@Autowired
@Qualifier("flowRuleNacosProvider")
private DynamicRuleProvider<List<FlowRuleEntity>> ruleProvider;
@Autowired
@Qualifier("flowRuleNacosPublisher")
private DynamicRulePublisher<List<FlowRuleEntity>> rulePublisher;

6. Modify rule query , Rule change entry
 

7. Modify... In the same way DegradeController file

Usage mode

1. Self deploy after packaging

mvn clean package

2. function sentinel-dashboard.jar

You need to specify the nacos Service address ,nacos.address: 127.0.0.1:8848

Appoint nacos Namespace ,nacos.namespace: appName-sentinel

java -jar -Xms768m -Xmx768m -XX:PermSize=512M -XX:MaxPermSize=512M -Dfile.encoding=UTF-8 -Dnacos.namespace=appName-sentinel -Dnacos.address=127.0.0.1:8848 sentinel-dashboard.jar

3. nacos Add the corresponding namespace on

4. sentinel It's inertia , The interface link will not be displayed until the interface is called

5. Fuse according to the link configuration , Current limiting rules

6. testing nacos Whether there is a corresponding rule configuration in
