CentOS 7にMySQL 8.0をインストール(SCL)

More than 1 year has passed since last update.

はじめに

Software Collection(SCL)を利用してCentOS7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:Quick Start — Software Collections

サポート

本手法で導入した場合、Red Hat Software Collections Product 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。
