MySQL已損壞，無法啓動：「從雙寫緩衝區中恢復可能的半寫數據頁...」

Question

當試圖啓動mysql服務器時，它返回退出代碼1.我已經完成了這一百萬這個服務器之前的時間。 在上個月沒有搞亂服務器，mysql突然停止，我無法啓動它。我的error.log：

[Note] InnoDB: Using mutexes to ref count buffer pool pages

Everything goes to ruin below this line.

，直到我能啓動mysql服務器，我不能運行mysqldump也不mysql -u root：

Got error: 2002: "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")" when trying to connect 

我正在MariaDB的服務器10.1.23-9-deb9u1。

Answer 1

不知道這是否會工作，但由於服務器不反正工作，所以嘗試了這一點：

重命名logfile0和logfile1，然後重新啓動服務器。

在做任何事之前，將整個mysql文件夾複製到另一個位置以防萬一。

Answer 2

答案是我的右盈：

InnoDB: Set innodb_force_recovery to ignore this error. 

我設置innodb_force_recovery = 1我/etc/mysql/mariadb.conf.d/50-server.cnf的[mysqld]子句後（該文件很可能視操作系統而定）。

我重新啓動它並自行修復。我後來拿出innodb_force_recovery = 1並重新啓動，然後它工作得很好。

我學到了什麼？對「自動修復」程序有更多的信心。由於我接觸到Microsoft Windows，我的期望對他們來說太低了。
