Question

在Windows 10计算机上的XAMPP安装中，MySQL服务将不再启动。 XAMPP控制台中的错误消息显示：

错误：MySQL意外关闭。这可能是由于端口阻塞，缺少依赖项，特权不当，崩溃或其他方法关闭导致的。

错误日志显示如下：

Windows事件查看器包含5条单独的错误消息：

mysqld.exe: Table '.\mysql\db' is marked as crashed and should be repaired
mysqld.exe: Index for table '.\mysql\db' is corrupt; try to repair it
Couldn't repair table: mysql.db
Fatal error: Can't open and lock privilege tables: Index for table 'db' is corrupt; try to repair it
Aborting

尝试连接到MySQL时，它不起作用（这很有意义，因为MySQL服务将无法运行）。这是尝试连接ERROR 2002 (HY000): Can't connect to MySQL server on 'localhost' (10061)后在CMD中给出的错误消息。

与需要修复的MySQL表相关的帖子需要连接到MySQL，因此在这种情况下无济于事。如果可以在Windows 10计算机上修复mysql.db而无需连接MySQL，该怎么做？

这对我有帮助：

从控制面板打开外壳，并使用以下命令启动mysql：
mysqld –-console –-skip-grant-tables –-skip-external-locking
从控制面板打开另一个外壳，并使用以下命令修复数据库：
mysqlcheck -r --databases mysql --use-frm
停止mysql，关闭外壳并正常重启mysql。
