MySQL莫名地报错：
2020-12-08T02:02:32.179362Z 0 [ERROR] InnoDB: The innodb_system data file 'ibdata1' must be writable 2020-12-08T02:02:32.180017Z 0 [ERROR] InnoDB: The innodb_system data file 'ibdata1' must be writable 2020-12-08T02:02:32.180530Z 0 [ERROR] InnoDB: Plugin initialization aborted with error Generic error 2020-12-08T02:02:32.395955Z 0 [ERROR] Plugin 'InnoDB' init function returned error.
解决方案：
1、打开“任务管理器”，终止MySQL进程；
2、打开MySQL安装目录的data文件夹，删除以下2个文件：ib_logfile0 和 ib_logfile1；
3、重新启动MySQL；
