以下のエディターは、記事 MySQL グループ レプリケーションの構成手順 (推奨) を提供します。編集者はこれが非常に良いものだと思ったので、皆さんの参考として今から共有します。エディターをフォローして見てみましょう
MySQL-Group-Replication は、mysql-5.7.17 バージョンで開発された新機能であり、マスターとスレーブ間の強力な一貫性を実現します
が、現時点では主にパフォーマンスが優れていません。 。
【1】現在のmysqlデータベースのバージョンが5.7.17以降であることを確認してください
/usr/local/mysql/bin/mysqld --version /usr/local/mysql/bin/mysqld Ver 5.7.17 for linux-glibc2.5 on x86_64 (MySQL Community Server (GPL))
【2】実験環境は1台のホストに3つのmysqlをインストールし、その3つでグループを形成します-レプリケーショングループ
