nacos 如何同步 zk的配置

nacos zookeeper数据迁移

        

官网：https://nacos.io/zh-cn/docs/nacos-sync-use.html

nacos-sync：https://github.com/nacos-group/nacos-sync

        

             

                                   

nacos-sync

     

nacos-sync 支持迁移的数据中心

             

  1. nacos <==> nacos：支持0.8到1.0及以上版本的nacos数据迁移
  2. nacos <==> consul：只支持spring cloud注册中心数据迁移
  3. nacos <==> euraka：只支持spring cloud注册中心数据迁移
  4. nacos <==> zookeeper：只支持dubbo注册中心数据迁移

                

下载 nacos-sync，并编译jar包

  1. git clone https://github.com/nacos-group/nacos-sync.git
  2.  
  3. cd nacosSync
  4. mvn clean package -U

          

nacos-sync 配置文件：application.properties

  1. server.port=8083
  2. server.servlet.context-path=/
  3.  
  4. spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
  5. spring.jpa.hibernate.ddl-auto=update
  6. spring.jpa.properties.hibernate.show_sql=false
  7.  
  8. spring.cloud.discovery.enabled=false
  9.  
  10. spring.datasource.url=jdbc:mysql://localhost:3306/nacos_sync?characterEncoding=utf8&connectTimeout=10000&socketTimeout=30000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
  11. spring.datasource.username=root
  12. spring.datasource.password=root
  13.  
  14. management.endpoints.web.exposure.include=*
  15. management.endpoint.health.show-details=always

            

数据库建表sql：nacosSync.sql（一般会自动创建，不需要手动创建）

  1. /******************************************/
  2. /*   DB name = nacos_sync   */
  3. /*   Table name = cluster   */
  4. /******************************************/
  5. CREATE TABLE `cluster` (

  14. ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;
  15. /******************************************/

  25. ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;
  26. /******************************************/
  27. /*   DB name = nacos_sync   */
  28. /*   Table name = task   */
  29. /******************************************/
  30. CREATE TABLE `task` (

nacos-sync 启动

    

创建mysql，并创建nacos_sync数据库

  1. # 创建mysql容器
  2. docker run -it -d --net fixed --ip 172.18.0.10 -p 3307:3306 \
  3. -e MYSQL_ROOT_PASSWORD=root --name mysql2 mysql
  4.  
  5. # 创建nacos_sync数据库
  6. mysql> create database nacos_sync;
  7. Query OK, 1 row affected (0.01 sec)

nacos-sync配置文件：修改数据库配置

  1. # 端口默认为8083
  2. ​server.port=8083
  3. server.servlet.context-path=/
  4.  
  5. spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
  6. spring.jpa.hibernate.ddl-auto=update
  7. spring.jpa.properties.hibernate.show_sql=false
  8.  
  9. spring.cloud.discovery.enabled=false
  10.  
  11. # 数据库地址、用户名、密码
  12. spring.datasource.url=jdbc:mysql://localhost:3307/nacos_sync?characterEncoding=utf8&connectTimeout=10000&socketTimeout=30000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
  13. spring.datasource.username=root
  14. spring.datasource.password=root
  15.  
  16. management.endpoints.web.exposure.include=*
  17. management.endpoint.health.show-details=always
  18. ​
