I did try reinstalling, using AppleWS, and some fixes that i found here. None of them worked.

Answer 1

These lines:

2014-10-28 14:14:38 3768 [ERROR] InnoDB: C:\xampp\mysql\data\ibdata1 can't be opened in read-write mode

2014-10-28 14:14:38 3768 [ERROR] InnoDB: The system tablespace must be writable!

.. indicate a problem with permissions.

Check the permissions on C:\\xampp\\mysql\\data\\ibdata1 and ensure that whatever user you're running your server under has read/write access to that folder.

Answer 2

I solved the problem following the following steps:

1. I moved all files and directories from C:\\xampp\\mysql\\data\\ to another directory.
2. I started MySQL from XAMPP to generate new files.
3. I moved not generated files and directories to C:\\xampp\\mysql\\data\\ .

This method didn't make me lost my configuration and my databases

Answer 3

只需删除C:\\xampp\\mysql\\data\\文件夹中的ibdata1和iblog文件。
