MySQL沒有在XAMPP上啓動

Question

我無法通過XAMPP啓動MySQL，上次在幾個月前打開它時沒有問題;

更新錯誤，我也跟着my.cnf中恢復後：

基礎上的錯誤日誌的建議，我想你應該試試這個。我計劃在評論中寫這個，但這很難讓你閱讀，所以我將它作爲一個回答，而不是

你不能啓動MySQL，因爲XAMPP無法打開文件.\mysql\innodb_index_stats.ibd，如

Error: could not open single-table tablespace file .\mysql\innodb_index_stats.ibd 

這裏是建議如何解決它：

1) If there is a permission problem in the file and mysqld cannot 
open the file, you should modify the permissions. 

（1）關於許可。轉到.\mysql\innodb_index_stats.ibd並檢查是否有權限讀取innodb_index_stats.ibd

2) If the table is not needed, or you can restore it from a backup, 
then you can remove the .ibd file, and InnoDB will do a normal 
crash recovery and ignore that table. 

（2）你可以嘗試刪除.\mysql\innodb_index_stats.ibd。我的建議是複製innodb_index_stats.ibd到另一個位置，以防萬一別的發生

3) If the file system or the disk is broken, and you cannot remove 
the .ibd file, you can set innodb_force_recovery > 0 in my.cnf 
and force InnoDB to continue crash recovery here. 

（3）如果你不能刪除nnodb_index_stats.ibd，你可以嘗試修改my.cnf文件，並設置innodb_force_recovery > 0（你可以用記事本或者記事本++編輯該文件。它定位xampp\mysql\

嘗試這些先來看看它是否有助於你

UPDATE 請嘗試查找文件ibdata1 LOCA TE在xampp\mysql\data和刪除或重新命名它，然後重新啓動XAMPP，希望這會工作，你
