Beanstalk 中的“未从实例接收到数据”状态。无法使用 SSH 或 FTP

Beanstalk 中的“未从实例接收到数据”状态。无法使用 SSH 或 FTP

我在 Beanstalk 上安装了 WordPress,并安装了 EC2 和 RDS。我对 AWS 还很陌生。昨天,网站变得没有响应,状态为“未从实例收到数据”。当我尝试请求完整日志时,它超时了。我无法通过 FTP 或 SSH 进入实例,因为它也超时了。我唯一看到的是系统日志,但我没有看到任何让我眼前一亮的东西。

查看事件,问题似乎从 4xx 错误开始,然后变成 5xx 错误。

以下是条目:

我不知道根本问题是什么。任何帮助或指导都将不胜感激。

答案1

我遇到过类似的问题,比如无法使用 SSH,也无法在 beanstalk 控制台中看到日志。问题是由于我的 t2.mini 实例导致内存不足。将实例类型更改为 t2.small 甚至 t2.medium,问题应该会得到解决(除非您的内存不足是由某些编码错误引起的)
