如何解决“错误:MySQL关机意外”?

当我打开XAMPP并单击启动MySQL按钮时，它给了我一个错误。我刚才启动了它，但现在它不工作了。

以下是错误日志的内容:

最重要的错误信息在这里:

2013-08-02 12:19:12 4536 [ERROR] InnoDB: 试图打开先前打开的表空间。以前的表空间mysql/innodb_table_stats在filepath: .\mysql\innodb_table_stats.ibd使用的是空间ID: 1。在文件路径:.\xat\payments.ibd下无法打开空间ID: 1的表空间xat/payments

日志的其余部分:

InnoDB: Error: could not open single-table tablespace file .\xat\payments.ibd InnoDB: We do not continue the crash recovery, because the table may become InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it. InnoDB: To fix the problem and start mysqld: InnoDB: 1) If there is a permission problem in the file and mysqld cannot InnoDB: open the file, you should modify the permissions. InnoDB: 2) If the table is not needed, or you can restore it from a backup, InnoDB: then you can remove the .ibd file, and InnoDB will do a normal InnoDB: crash recovery and ignore that table. InnoDB: 3) If the file system or the disk is broken, and you cannot remove InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf InnoDB: and force InnoDB to continue crash recovery here.

这些错误的原因是什么?我该如何纠正它们?

当前回答

我打开并清空存在于数据文件夹中的文件multi-master.info。这对我很管用。

其他回答

如果你不需要损坏表中的数据，你可以通过丢弃表空间来删除它:

ALTER TABLE sakila.actor DISCARD TABLESPACE;

之后，你可以删除表本身:

DROP TABLE sakila.actor;

如果第一步不起作用，首先替换actor。从具有相同结构的空表中复制Ibd文件。

Error: MySQL shutdown unexpectedly

This is the best answer 

1)Rename the folder mysql/data to mysql/data_old (you can use any name)
2)Create a new folder mysql/data
3)Copy the content that resides in mysql/backup to the new mysql/data folder
4)Copy all your database folders that are in mysql/data_old to mysql/data (skipping the mysql, performance_schema, and phpmyadmin folders from data_old)
5)Finally copy the ibdata1 file from mysql/data_old and replace it inside mysql/data folder
6)Start MySQL from XAMPP control panel

在Xamp中打开MuSQL配置文件，修改端口号为3307 这对我很有用:)

转到任务管理器，结束正在运行的MySQL任务，并在XAMPP中重新启动MySQL

对我来说，问题是:

由于项目规模太大，我习惯将电脑休眠，而不是关闭。我太懒了，重新打开了所有程序。

在尝试其他方法之前，我建议您做以下简单的事情。否则，你的MySQL服务器就会一团糟。

打开任务管理器并结束XAMPP进程。以管理员身份重新运行XAMPP应用程序。

如果不行，

保存所有未保存的程序，重新启动电脑。以管理员身份运行XAMMP。

另外，一定要检查3306和5040端口。在默认设置下运行MySQL需要这两个端口。
