Question

我正在使用MariaDB for windows。它是stange，在我用命令

更改root密码之前一切正常

USER 'root'@'localhost' IDENTIFIED BY 'password';

和

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('password');

（密码只是假的）

我无法通过以下命令启动数据库：

bin\mysqld.exe --defaults-file=my.ini --standalone --console

我已经尝试过将数据文件夹的chmod设置为777 ...

我现在收到以下错误：

C:\vayu_neu>mariadb\bin\mysqld.exe --defaults-file=mariadb\my.ini --standalone --console

Answer 1

您应该检查运行数据库配置文件（.ini）中innodb_data_home_dir指定的目录数据库的用户的权限，也许它是一个不同的目录

Answer 2

如果更改了目录，则修改或禁用SELINUX服务。这不允许在DATA目录更改后创建文件和启动MySQL。

Answer 3

删除文件ibdata1，ibdata2，ib_logfile0，ib_logfile1似乎解决了这个问题。我不知道为什么，但确实如此。

MariaDB ibdata1文件无法写入
