InnoDBがメモリを割り当てることができないためにMysqlがクラッシュする

MySQLは、my.cnfで設定されたinnodb-buffer-pool-size（現在は210M）を超える大きなリクエストが原因でクラッシュすることがあります。これは、mysqlが最初に起動するように設定する必要がありました。 。

エラーログは次のとおりです。

サーバーを再起動し、ここでmysqldを再起動しました。問題を一時的に修正しますが、再びクラッシュします。

次のパラメータを追加して、問題が解決したかどうかを確認します。
innodb_buffer_pool_instances = 3
innodb_change_buffering = inserts
innodb_flush_method = O_DIRECT
