我的MySQl服务器昨天工作正常，但是今天早上我突然得到了这个错误：

当我尝试mysqld

时

我试过了：

重新安装

Answer 1

[ERROR] InnoDB: ./ibdata1 can't be opened in read-write mode
[ERROR] InnoDB: The system tablespace must be writable!

听起来这个文件（以及其他文件）不能被mysqld正在运行的用户写入。检查您的文件权限。

该文件也可能已被删除。

Answer 2

如果您尝试使用.bat文件运行它，只需右键单击该文件，然后＆＃34;以管理员身份运行＆＃34;。我遇到了同样的问题并为我修复了身份。

MySQL错误，我已尽力而为
