Nacos 是 Dubbo 生态系统中重要的注册中心实现，其中 dubbo-registry-nacos 则是 Dubbo 融合 Nacos 注册中心的实现。
Nacos服务安装与启动安装地址： https://github.com/alibaba/nacos/releases
- 本文在Windows环境测试，下载zip版，解压。
- 配置conf目录下的application.properties文件，配置nacos数据源，端口等。
#*************** Spring Boot Related Configurations ***************# ### Default web context path: server.servlet.contextPath=/nacos ### Default web server port: server.port=8848 #*************** Network Related Configurations ***************# ### If prefer hostname over ip for Nacos server addresses in cluster.conf: # nacos.inetutils.prefer-hostname-over-ip=false ### Specify local server's IP: # nacos.inetutils.ip-address= #*************** Config Module Related Configurations ***************# ### If user MySQL as datasource: spring.datasource.platform=mysql ### Count of DB: db.num=1 ### Connect URL of DB: db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?serverTimezone=UTC&characterEncoding=utf8 db.user=root db.password=123456 #*************** Naming Module Related Configurations ***************# ### Data dispatch task execution period in milliseconds: # nacos.naming.distro.taskDispatchPeriod=200 ### Data count of batch sync task: # nacos.naming.distro.batchSyncKeyCount=1000 ### Retry delay in milliseconds if sync task failed: # nacos.naming.distro.syncRetryDelay=5000
初始化数据库，脚本位于conf目录下nacos-mysql.sql
启动nacos服务，在cmd中执行bin目录下startup.cmd：
D:>cd nacos/bin
D:nacosbin>startup.cmd
