Registry 注册中心配置

  • Nacos 注册中心
  1. dubbo:
  2.   application: # 应用信息，服务启动后会将相关信息注册到注册中心，可被客户端从 url 中识别
  3.     name: myApp # application=myApp; name=myApp
  4.     module: opensource # module=opensource
  5.     organization: dubbo # organization=dubbo
  6.     owner: laurence # owner=laurence
  7.     version: myversion # app.version=myversion
  8.     environment: pro # environment=pro
  9.   registries:
  10.     nacosWithCustomGroup:
  11.       protocol: nacos # 注册中心选择 nacos 
  12.       address: 127.0.0.1:8848 # nacos ip
  13.       group: myGroup # nacos group, 默认 DEFAULT_GROUP
  14.       namespace: 9fb00abb-278d-42fc-96bf-e0151601e4a1 # nacos namespaceID, should be created before. 默认public
  15.       username: abc
  16.       password: abc
  17.   protocols:
  18.     dubbo:
  19.       name: dubbo
  20.       port: 20000
  21.   provider:
  22.     services:
  23.       UserProviderWithCustomGroupAndVersion: # 接口三元组：接口名、版本号、分组。client 和 server 需要保持一致。
  24.         interface: org.apache.dubbo.UserProvider.Test # 接口名必填
  25.         version: myInterfaceVersion # 默认为空
  26.         group: myInterfaceGroup # 默认为空

dubbogo 的注册中心配置的 group、namespace、username、password，均与 nacos 相关概念对应。

  • Zookeeper 注册中心
  1. dubbo:
  2.   # application: 与nacos 一致，不再赘述
  3.   registries:
  4.     demoZK:
  5.       protocol: zookeeper # 注册中心选择 nacos 
  6.       address: 127.0.0.1:2181 # zookeeper ip
  7.       group: myGroup # nacos group, 默认 dubbo
  8.   protocols:
  9.     triple:
  10.       name: tri
  11.       port: 20000
  12.   provider:
  13.     services:
  14.       UserProviderWithCustomGroupAndVersion: # 接口三元组：接口名、版本号、分组。client 和 server 需要保持一致。
  15.         interface: com.apache.dubbo.sample.basic.IGreeter # 接口名必填
  16.         version: myInterfaceVersion # 默认为空
  17.         group: myInterfaceGroup # 默认为空

zookeeper 注册时，provider 端将接口信息注册在 /$(group)/$(interface)/providers 节点，以上面配置为例，注册的 zk path 为 /myGroup/com.apache.dubbo.sample.basic.IGreeter/providers/

consumer 端注册在 /$(group)/$(interface)/consumers 作统计用。

  • ETCD 注册中心
  1. dubbo:
  2.   registries:
  3.     etcd:
  4.       protocol: etcdv3
  5.       timeout: 3s
  6.       address: 127.0.0.1:2379
  7.   protocols:
  8.     dubbo:
  9.       name: dubbo
  10.       port: 20000
  11.   provider:
  12.     services:
  13.       UserProvider:
  14.         interface: org.apache.dubbo.UserProvider
  • 应用级服务注册发现
  1. dubbo:
  2.   registries:
  3.     demoZK:
  4.       protocol: zookeeper # nacos/zookeeper
  5.       address: 127.0.0.1:2181
  6.       registry-type: service # 使用应用级服务发现
  7.   metadata-report: # 配置元数据中心
  8.     protocol: zookeeper
  9.     address: 127.0.0.1:2181
  10.   protocols:
  11.     triple:
  12.       name: tri
  13.       port: 20000
  14.   provider:
  15.     services:
  16.       GreeterProvider:
  17.         interface: com.apache.dubbo.sample.basic.IGreeter
