3. 配置 nacos 支持 MySQL

编辑 conf/application.properties (请根据实际情况修改)

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://mysql.jansora.app:3306/nacos-prod?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=nacos
db.password.0=nacos

启动 nacos
