总结：nacos-2.x.x要使用mysql5.7.x
项目使用若依3.1.0-cloud版本，因此要使用nacos-2.x.x的版本，下载并安装nacos后，
配置application.properties里的Config Module Related Configurations模块，
#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource:
spring.datasource.platform=mysql### Count of DB:
db.num=1### Connect URL of DB:
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=SYC
db.password.0=123
然后再启动startup.cmd时会报错，需要使用单机模式，
编辑startup.cmd，设置里面的MODE为standalone
set MODE="standalone"
set FUNCTION_MODE="all"
set SERVER=nacos-server
set MODE_INDEX=-1
set FUNCTION_MODE_INDEX=-1
set SERVER_INDEX=-1
set EMBEDDED_STORAGE_INDEX=-1
set EMBEDDED_STORAGE=""
再次启动时报错
2022-09-09 16:30:29,073 ERROR Startup errors :

看着No DataSource set猜测可能是链接数据库问题，使用的mysql为5.6.x
升级为5.7.x
再次启动成功
