上面报错了Error creating bean with name 'memoryMonitor' defined in URL，是数据库未连接上。

修改Nacos配置文件，安装目录nacos-server-2.1.0\conf\application.properties 中的数据库配置，如：

### Connect URL of DB:
spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://192.168.56.108:3306/ry-config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user=root
db.password=123456

继续启动操作下：

startup.cmd -m standalone

过程如下：

G:\WorkSoft\nacos\nacos-server-2.1.0\bin>startup.cmd -m standalone
"nacos is starting with standalone"
