我的解决方法，将derby 换成 mysql

2. 修改配置文件，需要注意的就是数据库url中的IP地址，需要换成真实的地址（我的是跑在docker中，所以就用了 172.17.0.1）

spring.datasource.platform=mysql
 
db.num=1
db.url.0=jdbc:mysql://172.17.0.1:3306/nacos_config?characterEncoding=utf8&serverTimezone=Asia/Shanghai&connectTimeout=1000&socketTimeout=3000&autoReconnect=true # 网络地址需要你实际的地址，localhost(127.0.0.1)环回测试地址并不可用
db.user=root # 替换成你自己的
db.password=123456 # 替换成你自己的

3. 解决
   

错误的解决方法!!!（删除derby）

这是一开始在某篇博客下看到的，删除掉derby后，nacos的数据会丢失，共享配置啥的…，错误的！
