Obtaining the Service Center Address of a ServiceComb Engine

The registry and discovery address is the core of service registry and discovery to implement dynamic service management. When a microservice is started, the registry center address is used to report its metadata (such as the IP address, port, service contract, and version) to the ServiceComb service center. This implements automatic service registry, avoids hard-coded addresses, and simplifies O&M. Service consumers use this address to query the list of available service instances from the registry center, select instances based on load balancing (such as weighted round robin), and dynamically detect service startup and shutdown (through heartbeats) to ensure that faulty instances are automatically removed, improving system fault tolerance.

The service center address cannot be changed after the engine is created.

1. Click the target engine.
2. In the Service Discovery and Configuration area, view the service center address of the microservice engine.

   

Obtaining the Configuration Center Address of a ServiceComb Engine

The configuration center manages microservice configurations. When a microservice is connected to the ServiceComb engine, you need to configure the configuration center address of the engine in the configuration file. ServiceComb establishes a persistent connection with the configuration center through this address. When detecting configuration changes, the configuration center pushes the changes to the microservice instance, and the configuration can be updated without restart, implementing dynamic configuration management.

1. Click the target engine.
2. In the Service Discovery and Configuration area, view the configuration center address of the microservice engine.

   

   

   • For ServiceComb engine 1.x, the port number of the configuration center address is 30103.
   • For ServiceComb engine 2.x, the port number of the configuration center address is 30110.
