Question

我从我认为是问题的开始开始：

我将一个mysql数据库从在线服务器导出到本地服务器，因此我可以在没有风险的情况下对其进行测试。

但是在XAMPP中我无法重启MySql模块。

11:02:54  [mysql]   Attempting to start MySQL app...

除了抛出此错误外什么都没做

10:57:49  [mysql]   Error: MySQL shutdown unexpectedly.
10:57:49  [mysql]   This may be due to a blocked port, missing dependencies, 
10:57:49  [mysql]   improper privileges, a crash, or a shutdown by another method.

10:57:49  [mysql]   the Windows Event Viewer for more clues
10:57:49  [mysql]   If you need more help, copy and post this
10:57:49  [mysql]   entire log window on the forums

我在网上查了一下，我找到的唯一可行的解决方案就是删除每次启动前的mysql / data / ibdata1文件。我知道它是一个肮脏的解决方案，但它有效，我不想浪费太多时间。

现在实际问题：我添加了一个新表。在下次重启（包括删除ibdata1文件）之后，我在phpMyAdmin的左栏中看到了这个表，但是当我点击“+”时它的完全空。当我点击名称时出现错误

#1146 table doesnt exist

如果我尝试创建一个同名的新表，我会得到同样的错误。

这是xampp日志文件：

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.

它在Windows 8上运行可能是关于缺少权限的东西，但我从c：\ program files \ xampp重新安装了xampp到c：\ xampp - ＆gt;同样的问题。我必须删除ibdata1才能启动它，然后我创建的每个新表都消失了。

在MySQL 5.6中似乎是known bug 他们还提到了一种解决方法：

[2012年11月27日8:39] Sunny Bains   这是bug＃67179的副本。只是不同的副作用。 Windows安装程序？显然复制了.ibd文件并导致了这个问题。 data / mysql中的那些。如果要恢复文件，则必须执行以下操作：


删除数据/ mysql / * .ibd文件和.ibd文件的相应.frm文件

使用--skip-slave-start
启动服务器
您应该能够访问和备份数据

我注意到，在关机时，你会再次失败。我需要调查这个问题的原因。我稍后会发布更新。

如果它不起作用，请尝试{X}与XAMPP相关的Restoring MySQL InnoDB Files on Windows。

MySql“表不存在”
