无法通过 SSH 连接到最近修补的服务器的 AMI 创建的 ec2

Question

我的一个 ec2 实例“patched-server-1”运行的内核版本是 4.18.0-240.1.1.el8_3.x86_64，然后我修补了该服务器，当前内核版本是 4.18.0-425.19.2.el8_7.x86_64，我可以 ssh 到该服务器，然后我从“patched -server-1”创建了一个 AMI 并启动了新的 ec2 实例“patched-server-2”，但我无法 ssh 到它。它给出连接被拒绝的错误。

原因：/etc/ssh 下缺少以下文件。当我使用升级内核的映像创建 ec2 实例时缺少这些文件，导致 sshd 服务启动失败，如果我仅从旧内核创建实例，则不会出现问题。
