将 Spring Boot 应用程序部署到 Elastic Beanstalk 时出现 502 Bad Gateway
Posted
技术标签:
【中文标题】将 Spring Boot 应用程序部署到 Elastic Beanstalk 时出现 502 Bad Gateway【英文标题】：502 Bad Gateway when deploying Spring Boot application to Elastic Beanstalk 【发布时间】：2019-07-27 11:25:35 【问题描述】：免责声明* 我知道对此有很多问题。我已经查看了它们并应用了答案，但它仍然不起作用。
我使用 .jar（不是 war）文件将 Spring Boot 应用程序部署到 Elastic Beanstalk。我正在使用 Java 1.8。我将 application.properties 更改为 server.port = 5000。我还在 0.0.0.0/32 上打开了我的 ec2 实例用于端口 5000 的安全组。当我的弹性 beantalk 环境加载时，状态变为降级。这是来自 EB 的日志文件。

【问题讨论】：
【参考方案1】：最可能的情况是应用程序服务器（嵌入 Spring Boot）没有正确启动。应用服务器的日志存储到/var/log/web-1.log，也可以通过 ElasticBeanstalk 中的 Logs 选项卡获得。
根据我的经验，这通常与无法访问支持的服务（数据库集群）有关。可能从您的 ElasticBeanstalk、EC2 环境到 RDS 数据库的安全组设置不正确。
【讨论】：
让我试试 RDS 安全组。 哇..这太简单了，我不敢相信我在这上面花了这么多时间...为我的 RDS 实例打开了安全组，它可以工作了。谢谢兄弟。 你是个天才以上是关于将 Spring Boot 应用程序部署到 Elastic Beanstalk 时出现 502 Bad Gateway的主要内容，如果未能解决你的问题，请参考以下文章
