Please set the JAVA_HOME variable in your environment, We need java(x64)! jdk8 or later is better!

环境变量中没有配置JAVA_HOME，添加该配置即可，记得修改path
JAVA_HOME路径到jdk即可，不需要到bin

[db-load-error]load jdbc.properties error

nacos默认为集群运行，改为单机版运行即可
修改start.cmd文件

rem set MODE="cluster"  集群运行
set MODE="standalone"        单机运行

No DataSource set

主要错误：The server time zone value ‘�й���׼ʱ��’ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
错误原因：是使用了 Mysql 最新版驱动

解决方法：
在项目代码-数据库连接 URL 后，加上 （注意大小写必须一致）
?serverTimezone=UTC
