以下のエディターは、IST 送信のみを必要とする新しいノードを構築するための記事MySQLPXC を提供します (推奨)。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
需要シナリオ: 元の pxc 環境には比較的大量のデータがあり、新しく購入したサーバーを SST ではなく IST で送信する方法を追加する必要があります。
PXC にはデータを送信する 2 つの方法があります: IST: 増分ステート転送増分同期
SST: ステート スナップショット転送完全同期
IST 発生条件: これはノード上のキャッシュ メカニズムを使用して行われます (つまり、クラスター内のノード データはまだ
キャッシュ内にあります
)
判定方法: mysql> show global status like 'wsrep_local_cached_downto';

したがって、私たちのアイデアはバックすることです。クラスター内のノードのデータをアップし、新しいノードに復元し、grastate.dat を作成してバックアップ データのシーケンス番号を記録します。これにより、新しいノードの起動時に、SST ではなく IST メソッドが自動的に使用されます ( gcache.size には十分な容量が必要であることに注意してください (バックアップおよびリカバリ期間中に新しく生成されたデータが確実にキャッシュされるようにするため)
galera.cache: This file is used as a main writeset store. It's implemented as a permanent ring-buffer file
that is preallocated on disk when the node is initialized. File size can be controlled with the variable
gcache.size. If this value is bigger, more writesets are cached and chances are better that the rejoining node will get IST instead of SST.
Filename can be changed with the gcache.name variable.

ステップ5: Xidの場所を調べる
方法は2つあります
方法1: ファイル11e6-9955-ae4d7e89eed2:8を表示します
方法 2 : ビンログの場所で検索:
[root@zejin241 I6000]# cat xtrabackup_binlog_infolog_bin.000003 2772つまり、バックアップ中のバックアップ ポイントの場所は log_bin.000003 2772 ですこのビンログを見つけるためにメイン データベースに行きましょうxid
[root@zejin240 I6000]# mysqlbinlog -vv log_bin.000003 | grep Xid#160528 9:02:59 サーバー ID 9816000 end_log_pos 947 CRC32 0x37371b3e Xid = 7#160528 10:03:04 サーバー ID 9 816000 終了ログ位置 2969 CRC32 0xf7973829 Xid = 9#160528 10:03:13 server id 9816000 end_log_pos 3168 CRC32 0x8db2aa41 Xid = 10
この場所に xid がないことがわかりました。その理由は、上部の mysql.user テーブルを更新したためです。このテーブルは myisam テーブルであり、Xid レコードはありません。この場合、上位と下位の位置に従って Xid を 8 に設定します
