Ruby on rails 使用Elastic Beanstalk创建时的AWS EC2.pem证书

我已按照指导使用Elastic Beanstalk安装了新应用程序。
现在我想通过ssh访问EC2服务器。我没有任何密钥对，所以我生成了新的密钥对，但仍然被拒绝了权限（publickey）

SSH跟踪：

您是如何配置Elastic beanstalk以使用密钥的？您是否遵循了此处描述的所有步骤：？have您以前使用过beanstalk，您有什么建议吗？我之所以使用它，是因为有一个很好的指南，这是google搜索响应中关于在AWS上部署Rails的第一个结果。我以前在ruby on Rails堆栈中使用过beanstalk。如果您正在寻找ruby的PaaS提供商，我建议heroku然后使用beanstalk。在任何给定的时间点，EC2都是b更好的选择，如果它是一个实验性的项目，尽管它也托管在EC2上
