zookeeper registration center

　　zookeeper is a sub-project of Apacahe Hadoop. It is a tree-type directory service that supports change push (< span style="color: #ff0000">When the information of the service provider changes, the information can be dynamically pushed to the consumer to allow the consumer to change the local information). It is suitable as a registration center for Dubbo services. The industrial intensity is relatively high. High, can be used in a production environment, and recommended to use

How zookeeper stores data to store data

　　 zookeeper is a tree-type directory structure, zookeeper stores data through nodes

　　http://mirrors.hust.edu.cn/apache/zookeeper/

< h3>3. Modify the zoo.cfg file

　　dataDir=D:/zkp/lo (the directory of data retained by zookeeper during runtime (node ​​data))

　　 start Success

　　zookeeper-3.4.12/bin/zkCli.cmd starts the client-side

6 .Service provider service consumer configuration registration center is zookeeper

7. Test

　　Start the server to execute service registration. Check the registered node data on the zkCli interface. Start the consumer to execute consumption
