私は、ビンログファイルbin.000008を持つマスターMySQLサーバAを持っています。そして、ビンログファイルbin.000012を持つスレーブサーバB。スレーブデータベースサーバからレプリケートすると、MySQLの複製が失敗する
AからBへの複製はうまく機能します。
データをサーバーAに変更するたびに、サーバーBはそれを正しく複製します。私はそれがサーバBに奴隷のように作る新しいMySQLサーバCがあります
問題がある：私は、サーバーA上のデータを変更すると
は、サーバBが正しくそれを複製します。しかし、サーバーCは変更されません。レプリケーションは、サーバBからサーバCに
無効であることを意味している私は、サーバーC.にスレーブを再起動しようとしましたが、それはバイナリログからデータを読み取る際がマスターから致命的なエラー1236を手に入れたと言う：「奴隷をCHANGE MASTER TO MASTER_AUTO_POSITION = 1を使用して接続していますが、マスターはスレーブが必要とするGTIDを含むバイナリログをパージしました。ここ
各サーバのマスタとスレーブの状態である。
サーバC（サーバBのスレーブ）：
