MySQLのログは問題が何であるかを明確に伝えます。
CentOSにMySQL 5.7をインストールしました[...]
2016-05-19T06:49:42.923623Z 0 [エラー]致命的なエラー：mysql.userテーブルが破損しています。 mysql_upgradeを実行してください。 2016-05-19T06:49:42.923679Z 0 [エラー] 中断中
MySQLがインストールされていません。あなた既存のアップグレードMySQLインストールでは、データベーススキーマを予想バージョン5.7にアップグレードする必要はありません。
そして、これらの人々...
... MySQLがデータベースを気に入らず、新しいスキーマにアップグレードするまでデータベースの起動を拒否することを知りました。
ビタリウス・レザコバスインストールユーティリティを使用してデータベース全体を再インストールすると、以前のデータはすべて失われます。
Redl Harald と呼ばれる~になるCentOSリポジトリに注意してください。 XeはOracleの独自の提案に応答します。一度に1つのバージョンレベルのみアップグレード。
ハラルドさんが言ったあの男の店は、レミーコレットと呼ばれる以前のバージョンのMySQLに再ダウングレードするには、データベースセット全体をファイルにダンプして再アップグレードし、ダンプから復元します。
Oracleは、docoでのアップグレードとダンプの回復方法について説明しています。前者は次のとおりです。内部アップグレード後者は論理アップグレード。
