Amazon Linux 是基于 CentOS 6 吗？我想升级我的 Amazon Linux 实例
[myuser@mymachine ~]$ uname -a
Linux sandbox2.evo-text.com 4.9.38-16.33.amzn1.x86_64 #1 SMP Thu Jul 20 01:31:29 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
CentOS 7，但我对如何做到这一点感到困惑。我可以“yum install update”，但我想知道是否必须更新位于 /etc/yum.repos.d/centos.repo 的“Centos.repo”文件

我是否需要更改文件的内容才能升级我的 Amazon Linux 实例？如果需要，它们需要是什么？
答案1
CentOS 并不意味着在主要版本之间进行升级，AWS 会告诉您销毁实例并使用 CentOS 7 AMI 启动一个新实例。
