502 bad gateway when I deploy SpringBoot application to AWS Elastic Beanstalk and cannot connect to RDS from local SpringBoot

问题

以下是您提供的内容的翻译部分：

我对AWS还不熟悉，我将部署我的StringBoot应用程序到AWS Elastic Beanstalk。我已经创建了RDS，并且我可以使用MySQL Workbench成功连接到它（没有建立模式）。但是当我将其部署到Elastic Beanstalk并运行时，我得到502错误坏的网关nginx/1.18.0。

另一个问题困扰着我，我无法使用本地SpringBoot连接到RDS。因此，当我将其打包成jar文件时，我让Maven跳过测试部分。我的yml文件如下所示。
在日志中，我发现显示：

Aug 18 22:45:10 ip-172-31-15-192 web: 2020-08-18 22:45:10.618  WARN 8134 --- [           main] o.h.e.j.e.i.JdbcEnvironmentInitiator     : HHH000342: 无法获取连接以查询元数据：未知数据库 'database-myblog'

这是否意味着与此数据库有什么问题，还是在运行之前我必须创建一个模式？

以下是一些yml文件示例；

英文:

I am new to AWS and I am going to deploy my StringBoot application to AWS Elastic Beanstalk. I already created rds and I can use mysql workbench to successfully connect to it(no schema built). But when I deploy it to Elastic Beanstalk and run it, I get error 502 bad gateway nginx/1.18.0.

Another problem brother me is I cannot connect to rds using local SpringBoot. So when I package it to jar file, I let maven skip test part. My yml(files) shown below.
In the log I fount it shows

Aug 18 22:45:10 ip-172-31-15-192 web: 2020-08-18 22:45:10.618  WARN 8134 --- [           main] o.h.e.j.e.i.JdbcEnvironmentInitiator     : HHH000342: Could not obtain connection to query metadata : Unknown database 'database-myblog'

Is that means something wrong with this database or do I have to create a schema before I run it?

Some yml files shown below;

  1. application.yml
spring:
  thymeleaf:
    mode: HTML
  profiles:
    active: prod

2 application-prod.yml

server:
  port: 5000

spring:
  datasource:

你需要将Elastic Beanstalk的安全组添加到RDS的入站规则中。你还可以添加你的IP地址，以允许从本地进行连接。
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/rds-external-defaultvpc.html

英文:

You need to add security group of your Elastic Beanstalk to your inbound rules for RDS. You can also add your ip address to allow connection from your local.
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/rds-external-defaultvpc.html
