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:

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: 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

上述解决方案对我来说都没用。然后我做了以下事情:

我删除了C:\xampp\mysql\data\目录下的所有文件,除了这个目录下的文件夹。 它工作得非常好,但我以前的数据库现在不能工作了。 所以,如果你不关心,上面会删除所有你以前的数据库在phpmyadmin。

其他回答

进入任务管理器 然后搜索mysqld,右键单击并选择END TASK并刷新XAMPP

以上的解决方案没有一个是无效的。它只是暂时有效。几天后,我们又一次面对同样的问题。我每次都失去了所有的脑起搏器。

我不知道确切的答案。但是,我一遍又一遍地做这3个简单的步骤。

将文件夹c:\xampp\mysql\data重命名为c:\xampp\mysql\data_old(可以使用任何名称)。 新建data文件夹c:\xampp\mysql\data 复制mysql\data_old中的所有数据库文件夹到mysql\data中

然后从XAMPP控制面板启动MySQL。

解决了!我用这个方法来解决它:

从控制面板打开shell并启动mysql:

mysqld –-console –-skip-grant-tables –-skip-external-locking

从控制面板打开另一个shell,用下面的命令修复数据库:

mysqlcheck -r --databases mysql --use-frm

停止mysql,关闭shell,正常重启mysql。

参见:https://stackoverflow.com/a/60576807/1662058

我也有同样的问题。 我的xampp控制面板将启动apache而不是mysql。 问题出在iblogfile中。 当你正在运行xampp/mysql时,你的电脑重新启动,而没有正确关闭innodb引擎。 进入xampp/mysql并删除

ib_logfile0

and

ib_logfile1

现在重新启动mysql,它应该工作。

Apache - >配置- >打开httpd . conf。搜索监听或80,更新监听端口到8081保存并重新启动服务器。 哦,如果你有Skype,关掉它。

移动xampp/mysql/backup文件到xampp/mysql/data 以管理员身份运行XAMPP(确保mysql已经安装,如果已经安装可以看到一个绿色的勾)

希望能有所帮助!
