CentOS 8にMySQL 8.0をインストール(AppStream)

Last updated at Posted at 2019-09-26

はじめに

Application Stream(AppStream)を利用してCentOS8にMySQL8.0をインストール
親記事:MySQL, MariaDBの各種インストール方法とEOLまとめ - Qiita
参考:RHEL8のパッケージ構成 - BaseOSとApplication Stream - 赤帽エンジニアブログ

サポート

本手法で導入した場合、Red Hat Enterprise Linux 8 Application Streams Life Cycle - Red Hat Customer Portalより、2023-04がEOLだと思われる。
それ以降に報告された脆弱性や不具合への対応は実施されない可能性がある。
なおCentOS Linux 8が2021-12にEOLを迎えるため、それ以降の更新を受けるためにはCentOS Stream8を含めた他ディストリビューションへの移行が必要。
