AWS Amazon Linux MySQL Yum 更新失敗

我使用 Amazon Linux AMI SSH 連接到我的 AWS EC2 實例，它告訴我執行sudo yum update命令以進行安全更新。當我這樣做時，它最終無法更新 MySQL。

*我不知道這是否是原因，但請注意，我的 MySQL 設置為通過以下方式安裝綁定到附加的 EBS 文件系統：http ://aws.amazon.com/articles/1663?_encoding=UTF8&jiveRedirect=1

這是輸出：

Complete!

通常，當文件出於安全原因設置了不可變 (i) 標誌時，就會發生這種情況。

lsattr /etc/my.cnf

chattr -i /etc/my.cnf

在 Amazon EBS 的情況下，看起來文件綁定到 EBS 卷上的一個：只是umount /etc/my.cnf，執行更新並bind再次執行。
