在新生产服务器上上传文件时出现 PermissionError

Question

我将 Django 项目迁移到新的生产服务器。在以前的生产服务器上，一切正常。迁移时，我升级到 Ubuntu 20.04 和 Django 4.0.3。现在一切都恢复正常了，除了上传文件。

当我尝试创建 Invoice 对象的实例时，只要我不尝试随它一起上传文件，它就可以工作。添加带有文件的发票会出现以下错误：

文件已上传到正确的（cifs 安装）文件夹，但由于某些原因，无法将包含文件 link 的对象实例添加到数据库中？

我想问题是某种权限问题。我尝试通过将所有内容设置为 777 来解决此问题，因此我至少可以看到这是否解决了问题，但事实并非如此。当前 /var/www/html/media 的文件夹权限为：

drwxrwxrwx 2 root root 0 Mar 17 08:57 发票

chown 出于某种原因不起作用（我读到这与 cifs 挂载有关？），但 var-www 也不是以前服务器上发票文件夹的所有者，而且工作正常...

非常感谢任何帮助！

Answer 1

我找到了解决方案。

我必须将 uid=www-data,forceuid 添加到 cifs 挂载命令。 apache 用户没有正确的权限。

(然后卸载，再挂载)
