其中，nacos配置mysql的步骤

1. 新建数据库nacos_config, 执行sql脚本生成表单
2. 在application.properties下配置mysql相关属性
3. 启动# 欢迎使用Markdown编辑器

一般都是在配置application.properties文件时出了问题, 如果直接照抄官方文档会报错, 因为mysql8.0之后的版本, 需要在官网文档配置mysql的基础上加上mysql时区的设置

正确的配置如下:
spring.datasource.platform=mysql

db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&serverTimezone=UTC&connectTimeout=10000&socketTimeout=30000&autoReconnect=true
db.user=我的mysql用户名
db.password=我的密码

注：尽量按照上述所配置的信息进行完善，否则会出现异常，本人之前采用下面方案1，就需要手动先连接数据，nacos才可连接成功，否则就会提示nacos连接数据库异常；但是使用方案2就可以一次性连接数据

1. db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=10000&socketTimeout=30000&autoReconnect=true&serverTimezone=UTC&useUnicode=true&useSSL=false
2. db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=10000&socketTimeout=30000&autoReconnect=true&serverTimezone=UTC
