【nacos2.2.1本地启动】

@nacos2.2.1本地启动填坑之行

下载nacos代码

nacos文档地址：https://nacos.io/zh-cn/docs/quick-start-spring.html

github地址下载代码：https://github.com/alibaba/nacos.git

appllo文章：https://blog.51cto.com/muxiaonong/3933418

下载完成后idea呈现：

启动naocs

1、找到nacos中console服务

2、配置启动参数，指定为单机：-Dnacos.standalone=true

3、执行sql

4、application.properties中修改sql配置

4、application.properties中修改secret.key配置

# 随便填写key
nacos.core.auth.plugin.nacos.token.secret.key=123jiosjoijodjaosidj123123123123123123123123

5、不填写key后果

原因：nacos 2.2.1版本及以后开启了默认鉴权，需要填写jwt key，
