Ubuntu 18.04 上的 SQL Server 操作系统错误 2（系统找不到指定的文件。）

[英]SQL Server on Ubuntu 18.04 Operating system error 2(The system cannot find the file specified.)

原文 2018-09-03 07:57:28 1 1 sql-server/ ubuntu/ sqlcmd

I am trying to backup database on sql server with : BACKUP DATABASE [mydb] TO DISK = N'/path/to/file.bak' WITH NOFORMAT, NOINIT, NOSKIP, REWIND, NOUNLOAD, STATS = 10我正在尝试在 sql server 上备份数据库： BACKUP DATABASE [mydb] TO DISK = N'/path/to/file.bak' WITH NOFORMAT, NOINIT, NOSKIP, REWIND, NOUNLOAD, STATS = 10

It creates backup if the path is /var/opt/mssql/data/file.bak cannot create backup in any other location.如果路径为/var/opt/mssql/data/file.bak则创建备份无法在任何其他位置创建备份。 Is this a permission issue?这是权限问题吗？ Does any one had faced the same?有没有人遇到过同样的情况？ Thanks in advance.提前致谢。

SQL Server on Linux (on Ubuntu) runs under the user mssql . Linux（在 Ubuntu 上）上的 SQL Server 在用户mssql下运行。 If you want SQL Server to be able to write to that folder, then either the user/group mssql needs write acces to the folder (and able to read/execute any parent folders), the mssql user needs to be part of a group that can, or the permissions for others needs to be set to write.如果您希望 SQL Server 能够写入该文件夹，则用户/组mssql需要对该文件夹进行写入访问（并且能够读取/执行任何父文件夹），则mssql用户需要成为该组的一部分可以，或者需要设置其他人的权限才能写。 Again, all parent folders need to allow access (read/execute).同样，所有父文件夹都需要允许访问（读取/执行）。

If you had a Folder /backups , for example, owned by root: with the permissions 770 , and then a folder /backups/SQLServer/ owned by root:mssql with the permission 775 , then SQL Server would be unable to write to the folder, as it wouldn't have been able to navigate to the folder /backups .如果您有一个文件夹/backups ，例如，由root:拥有，权限为770 ，然后文件夹/backups/SQLServer/由root:mssql拥有，权限为775 ，则 SQL Server 将无法写入该文件夹，因为它无法导航到文件夹/backups 。
