nacos启动报错 No DataSource set 的骚操作

前言：配置好的nacos一直都可以用，但是重启服务器后突然启动报错

一、报错信息

数据库一直是可以连接的，但是重启服务器后启动就报这个错误

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'memoryMonitor' defined in URL [jar:file:/opt/nacos/target/nacos-server.jar!/BOOT-INF/lib/nacos-config-2.0.3.jar!/com/alibaba/nacos/config/server/monitor/MemoryMonitor.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'asyncNotifyService': Unsatisfied dependency expressed through field 'dumpService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'externalDumpService': Invocation of init method failed; nested exception is ErrCode:500, ErrMsg:Nacos Server did not start because dumpservice bean construction failure :

二、解决方案

使用navicat连接数据库，随便执行一个mysql命令，比如：

select * from table_name(表名)

点击执行，最好在nacos_log数据库和自己的业务数据库都执行一下，再启动nacos就可以启动成功了
