上传文件时Django的权限被拒绝错误

Question

我目前有一个简单的模型定义,使用django缩略图插件的photoupload功能.

但是当我尝试上传时,它给出了以下错误:

OSError at /admin/products/photo/add/

(13, 'Permission denied')

现在,我知道这似乎是一个权限问题,所以我检查的第一件事是对目录的权限,并将这些更改为777(只是测试),重新启动服务器和fcgi,它仍然给出错误.

正在运行FCGI守护程序的用户肯定有访问该目录的读写权限.

来自settings.py

MEDIA_ROOT = '/var/www/sites/gang/http/media/'
MEDIA_ROOT_URL = '/media/'

Answer 1

我刚遇到同样的问题.如果您使用Apache作为服务器托管,则找到解决方案.例如,如果我的设置是:

MEDIA_ROOT ='/ var/www/media/geekingreen'

然后我只需要递归地给该文件夹正确的权限,以确保任何子文件夹也具有相同的权限.apache的默认组是www-data,所以为了给我的django app提供权限,我会运行这些命令.

cd /var/www/media
chgrp -R www-data geekingreen/
chmod -R g+w geekingreen/

该chgrp命令-R www数据geekingreen /命令改变目录geekingreen和任何子目录具有组WWW的数据.
在搭配chmod -R G + w ^ geekingreen /命令改变什么权限的组对所有这些文件夹,现在属于www数据的,到现在已经有写权限.显然需要上传.

希望这可以帮助任何可能遇到类似问题的人.

尝试检查从/开始的路径中每个目录的权限.只是一个想法.
