MYSQL：崩潰或關閉後不支持升級 innodb_fast_shutdown = 2

我有一個在 docker 容器中執行的 mysql 伺服器。我嘗試將數據庫從版本 8.0.29 升級到版本 8.0.30。但是，在啟動時，出現以下錯誤：

2022-09-06T13:13:39.928986Z 0 [System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.30) starting as process 1

2022-09-06T13:13:41.328299Z 0 [ERROR] [MY-010119] [Server] Aborting

然後我嘗試在版本 8.0.29 中重新開始，但這也不再有效 - 錯誤消息是：

2022-09-06T13:31:18.544142Z 0 [System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.29) starting as process 1

有什麼想法可以解決這個問題嗎？

首先備份你的mysql數據目錄。然後刪除文件 ib_logfile*. 當您啟動 mysql 時，它將創建新的空日誌文件。

此外，與執行innodb_fast_shutdown = 2是一個壞主意。將其更改為 1。您仍然可以快速關閉，但 mysql 將盡最小可能使您的文件進入一致的、可升級的狀態。正如您所發現的，這在執行 Docker 時很重要，因為您的軟體版本可以獨立於您的數據。
