1. 安装nacos

nacos安装包 以widows为例 image.png 解压后进入nacos\conf目录下，修改 application.properties 配置

# 默认鉴权插件用于生成用户登陆临时accessToken所使用的密钥，使用默认值有安全风险 (2.2.0.1后无
默认值)
nacos.core.auth.plugin.nacos.token.secret.key=VGhpc0lzTXlDdXN0b21TZWNyZXRLZXkwMTIzNDU2Nzg=

注意：在2.2.0.1版本后，社区发布版本需要自行填充nacos.core.auth.plugin.nacos.token.secret.key
的值，否则无法启动节点

配置参考：鉴权 image.png

修改启动方式： 配置完成后进入 nacos\bin 目录 image.png

双击 startup.cmd 启动nacos image.png 启动成功

2. 新建工程 nacos-demo

引入依赖

<!-- nacos服务注册与发现 -->
<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>

Spring Cloud Alibaba版本选择 参考：版本说明

配置application.properties

# 端口
server.port=18080
# 服务名称
spring.application.name=mall-user

# 配置nacos注册中心地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848
# 配置nacos注册中心地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

启动服务 启动类上添加@EnableDiscoveryClient注解，此注解可以省略

启动后登录 http://localhost:8848/nacos 查看服务是否注册成功 image.png
