我最近在我的arch

linux盒子上安装了mariadb,并希望用不同的数据和tmp目录运行

mysqld

[mysqld]

user = mysql

port = 3306

datadir =

tmpdir = /tmp

运行mysqld时,我收到以下错误消息：

InnoDB: The InnoDB memory heap is disabled

InnoDB: Mutexes and rw_locks use GCC atomic builtins

InnoDB: Compressed tables use zlib 1.2.8

InnoDB: Using Linux native AIO

[ERROR] mysqld: Can't create/write to file '/tmp/ib8dOkCX' (Errcode: 13)

InnoDB: Error: unable to create temporary file; errno: 13

[ERROR] Plugin 'InnoDB' init function returned error.

[ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.

[ERROR] mysqld: Can't create/write to file '/aria_log_control' (Errcode: 13)

[ERROR] mysqld: Got error 'Can't create file' when trying to use aria control file '/aria_log_control'

[ERROR] Plugin 'Aria' init function returned error.

[ERROR] Plugin 'Aria' registration as a STORAGE ENGINE failed.

[ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

[ERROR] Unknown/unsupported storage engine: InnoDB

[ERROR] Aborting

[Note] mysqld: Shutdown complete

我确保mysql用户是所有者,并且对数据和tmp目录具有适当的权限.

当以root身份运行mysqld时,一切正常.当使用默认的tmpdir时,我仍然在创建/写入文件/ aria_log_control时收到错误.谁知道我失败的地方？
