docker logs -f containter_id

Caused by: com.alibaba.nacos.api.exception.NacosException: Nacos Server did not start because dumpservice bean construction failure :No DataSource set

进一步查看 容器内错误日志 /home/nacos/logs/nacos.log

报错开始行

2022-11-10 16:03:34,323 ERROR HikariPool-1 - Exception during pool initialization.java.sql.SQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

后面找到一行关键错误

Caused by: com.mysql.cj.exceptions.CJException: Access denied for user 'root'@'host.docker.internal' (using password: YES)

一般来讲本地数据库是不会放开远程连接的 所以我这边是新建一个用户 并授权 开始远程连接
创建nacos用户

create user 'nacos'@'%' identified by '123456';

将nacos数据管理权限授权给nacos

grant all privileges on nacos.* to `nacos`@'%';

将新配置刷新到缓存中，这样就不用重启数据库

flush privileges;

修改配置
application.properties文件

再次启动
