1. Preparations
- dubbo-go cli tools and dependent tools have been installed
- Create a new demo application
- Start a Nacos instance and expose port 8848
2. Configure the registration center
Modify the server configuration go-server/conf/dubbogo.yaml
dubbo:
registries:
nacos: # configure Nacos registration center
protocol: nacos
address: 127.0.0.1:8848 # Specify Nacos address
protocols:
triple:
name: tri
port: 20000
provider:
services:
GreeterProvider:
interface: "" # read from pb
Modify client configuration go-client/conf/dubbogo.yaml
dubbo:
registries:
nacos:
protocol: nacos
address: 127.0.0.1:8848
consumer:
references:
GreeterClientImpl:
protocol: tri
interface: "" # read from pb
3. Use Nacos for service discovery
Start go-server/cmd and check the log
[Nacos Registry] Registry instance with param ...The log contains Nacos registration information, and the current service interface is registered in Nacos.
You can log in to the console http://localhost:8848/nacos to view the registered services
Start go-client/cmd to view logs
[Nacos Registry] Update begin, service event: ServiceEvent{Action{add}, Path{tri://xxx.xxx.xxx.xxx:20000/api.Greeter ...The log contains the subscription event information of the Nacos registration component, and the server IP and port number are obtained, indicating that the call is successful.

4. More supported registries
Reference dubbo-go-samples/registry 修改服务端配置 go-server/conf/dubbogo.yaml
dubbo:
registries:
nacos: # 配置 Nacos 注册中心
protocol: nacos
address: 127.0.0.1:8848 # 指定 Nacos 地址
protocols:
triple:
name: tri
port: 20000
provider:
services:
GreeterProvider:
interface: "" # read from pb
修改客户端配置 go-client/conf/dubbogo.yaml
dubbo:
registries:
nacos:
protocol: nacos
address: 127.0.0.1:8848
consumer:
references:
GreeterClientImpl:
protocol: tri
interface: "" # read from pb
3. 使用 Nacos 进行服务发现
启动go-server/cmd，查看日志
[Nacos Registry] Registry instance with param ...日志中包含 Nacos 注册信息，将当前服务接口注册在 Nacos。
可登陆控制台 http://localhost:8848/nacos 查看注册的服务
启动 go-client/cmd 查看日志
[Nacos Registry] Update begin, service event: ServiceEvent{Action{add}, Path{tri://xxx.xxx.xxx.xxx:20000/api.Greeter ...日志中包含 Nacos 注册组件的订阅事件信息，获取到服务端 IP 和端口号，显示调用成功。
