我有一个网页，使用
我的Django网页上的下载视图如下（虽然我很确定错误不在这个片段中）：
因此，我的问题是：为了能够访问位于
Nginx + Uwsgi + Django 技术，并且我在其中设置了一个外部路径 /download 用于管理 Django 中的下载（用户凭证），以及内部路径 /download-nginx 用于实际下载目录 /var/wwww/download 中的文件。为了试验，我尝试使用我的用户名和默认的 nginx 用户进行操作，但两者都在 Nginx 中遇到了权限被拒绝的错误。open() "/var/www/download/example.txt" failed (13: Permission denied)
我读过 Stack Overflow 上的一些其他解决方案，它们都说问题在于 nginx.conf 中提供的用户没有足够的权限。但事实上，他们已经拥有足够的权限：
$ sudo -u nginx stat /var
File: ‘/var’
Size: 4096 Blocks: 8 IO Block: 4096 directory

此外，以防万一，我已经对目录/var/wwww/download递归执行了chmod 777操作。

我的Django网页上的下载视图如下（虽然我很确定错误不在这个片段中）：
def download(request):
# Auth code is ommitted #
response = HttpResponse()
path = "/var/www/download/example.txt"
name = "example.txt"
response['Content-Length'] = os.path.getsize(path)
response['X-Accel-Redirect'] = "/download-nginx/{0}".format(name)
del response['Content-Type']
del response['Content-Disposition']
del response['Accept-Ranges']
del response['Set-Cookie']
del response['Cache-Control']
del response['Expires']
return response
因此，我的问题是：为了能够访问位于
/var/www/download上的数据并将其提供给用户作为可下载元素，我应该在我的Centos机器上做什么？
