mysqlプロセスが終了する原因（クリーン）

Layer7と呼ばれるAPIマネージャーにmysql master-master（バージョン5.5.32）を使用しています。インスタンスを保持する2つのホストは同じESXにあります

時々、今のところmysqlはクリーンシャットダウンを実行しています。

Cronjobsをチェックしましたが、どれもありませんこの期間中にホストまたはインスタンスへのログインをチェックしましたが、何もありませんでした。

手動でのシャットダウン、スクリプトまたはアプリからのシャットダウン、またはマスター/マスター構成でクリーンシャットダウンを引き起こす可能性がある強制終了によるシャットダウン以外

これはインスタンスが停止したホストのログです

ありがとうございました

よろしく

SHUTDOWN特権は、mysqladminを実行している場合にのみ使用できます

SHUTDOWN grant を削除すると、ユーザーはmysqladmin shutdownを実行できなくなります。

あなたの実際の問題

質問に表示されているエラーログは、mysqldの再起動です。

mysqladminはmysqldを起動または再起動できません。

誰かが何かを実行していますservice mysql restart

最初に履歴を実行する

# history | grep restart

表示される再起動に関連して何も起こらない場合は、service mysql restartを実行しているDBサーバーでcronjobを見つける必要があります。場合によっては、誰も覚えていないリモートサーバー上のcronjobである可能性があります。
