Zookeeper+dubbo, how to set up security authentication? You don't want other services to connect to Zookeeper because the Zookeeper server is on a public network.

Check the official documentation:

Zookeeper is a sub-project of Apacahe Hadoop, is a tree directory service, supports change push, is suitable to be used as a registry for Dubbo services, has high industrial intensity, can be used in production environment, and is recommended.

Process description:

When the service provider starts: write its own URL address to the / dubbo/com.foo.BarService/providers directory

When the service consumer starts: subscribe to the provider URL address under the / dubbo/com.foo.BarService/providers directory. And write your URL address to the / dubbo/com.foo.BarService/consumers directory

When the monitoring center starts: subscribe to all provider and consumer URL addresses under the / dubbo/com.foo.BarService directory

The following features are supported:
