我已经搜索过了，但找不到这个特定问题的答案。我已经设置并运行了 minidlna - 但设置得并不好。
首先，当我在蓝光播放器上打开服务器时，我的所有电影都会列出两次 - 而它们肯定不会在我的外部设备上保存两次。
其次，当我打开服务器时，它不会读取“电影”、“电视”、“音乐”等，而是将我所有的电影、电视和其他文件夹混在一起，没有任何组织。当我设置 Windows 时，我从未遇到过这个问题，所以我知道这是配置不当造成的，而不是我的外部驱动器给我带来的问题。
这是我的 minidlna.conf 文件：
# This is the configuration file for the MiniDLNA daemon, a DLNA/UPnP-AV media
# server.
#
# Unless otherwise noted, the commented out options show their default value.
#
# On Debian, you can also refer to the minidlna.conf(5) man page for
# documentation about this file.
media_dir=/media/somnambulist/Ghost In You
# This option can be specified more than once if you want multiple directories
# scanned.
#
# If you want to restrict a media_dir to a specific content type, you can
# prepend the directory name with a letter representing the type (A, P or V),
# followed by a comma, as so:
# * "A" for audio (eg. media_dir=A,/var/lib/minidlna/music)
# * "P" for pictures (eg. media_dir=P,/var/lib/minidlna/pictures)
# * "V" for video (eg. media_dir=V,/var/lib/minidlna/videos)
#
# WARNING: After changing this option, you need to rebuild the database. Either
# run minidlna with the '-R' option, or delete the 'files.db' file
# from the db_dir directory (see below).
# On Debian, you can run, as root, 'service minidlna force-reload' instead.
#media_dir=/var/lib/minidlna

这是我运行时在终端中出现的错误：
sudo service minidlna restart
sudo service minidlna force-reload
强制重启错误：

[ OK ]
到目前为止，我已经花了几个小时在这上面，阅读了各种文件 - 甚至有一个对 Ubuntu 比较熟悉的朋友试图通过聊天来帮助我 - 但没有那么幸运。
在此先感谢您的帮助。

错误在这里
rm: cannot remove ‘/home/somnambulist/serverart/files.db’: Permission denied
rm: cannot remove ‘/home/somnambulist/serverart/art_cache/media/somnambulist/Ghost In You/Movies/Slumdog Millionaire/Slumdog.Millionaire.Cover.jpg’: Permission denied

[2013/08/12 21:19:46] minidlna.c:744: warn: Failed to clean old file cache.
minidlna无法删除旧文件，因此失败。我遇到了同样的问题。删除旧Art_cache文件夹，然后重试。

我既不是 ubuntu 专家也不是 minidlna 专家 - 但我终于在 ubuntu server 12.04 上启动了我的 minidlna 服务器（今天！）并因此遇到了一些问题（并且知道如果你接近目标但却没有达到，你会有多么绝望）。
第一个怀疑：minidlna 混淆了其内部数据库中的某些内容。因此删除 files.db，在 Ubuntu 12.04 下，您需要类似以下内容（可能还需要 sudo）：
rm /var/lib/minidlna/files.db
然后重新启动 minidlna + 等待（它将重新创建文件）
第二个嫌疑人：你的路径中有一些空格：
/media/somnambulist/Ghost In You
Linux 和一些编程语言对此有点挑剔——如果没有正确处理，这可能会在 minidlna 内部引起一些问题。
请尝试：
/media/somnambulist/Ghost_In_You
（即更改目录的名称加minidlna.conf 文件中的设置）
对于第二个嫌疑人，您可能还需要再次删除 files.db。
无论第二名嫌疑人的结果如何 - 请发布结果，以便其他人也能从中受益。人们已经可以在网上找到第一名嫌疑人/线索。
没有保证——但值得一试。

您的问题是文件权限。如果您是 Linux 新手，那么您应该花一点时间了解文件权限如何工作。
minidlna 服务器作为单独的进程运行，并且通常会在 minidlna.conf 文件中指定用户名 minidlna。
# Specify the user name or uid to run as.
user=minidlna
数据库通常位于目录中
# Path to the directory that should hold the database and album art cache.
db_dir=/var/cache/minidlna
检查此目录的权限和所有者
~$ stat /var/cache/minidlna
File: /var/cache/minidlna
Size: 4096 Blocks: 8 IO Block: 4096 directory
Device: 801h/2049d Inode: 1967306 Links: 3
Access: (0750/drwxr-x---) Uid: ( 127/minidlna) Gid: ( 134/minidlna)
Access: 2020-04-26 11:39:36.340582338 +0100
Modify: 2020-07-07 08:35:11.796748628 +0100

Birth: 2020-04-26 11:39:36.340582338 +0100
在 Access 中，第一个 rwx 是所有者权限，rx 是组权限，最后一个 --- 是全局权限。因此 minidlna 用户可以读取、写入和执行此文件，执行位意味着当应用于目录时，您可以执行文件列表。要查看实际效果，请尝试：
~$ ll /var/cache/minidlna/
ls: cannot open directory '/var/cache/minidlna/': Permission denied
~$ sudo ls -l /var/cache/minidlna/
total 4504
drwxr-xr-x 3 minidlna root 4096 Jul 7 08:35 art_cache
-rw-r--r-- 1 minidlna root 4603904 Nov 8 01:47 files.db
在第一个 ll 命令中，我的普通用户没有此目录的 x 权限。但数据库文件的权限设置正确。
您提到的另一个问题是目录结构的压缩。这部分是客户端的功能，但如果客户端支持，请选择基于文件夹的呈现方式。默认情况下，minidlna 应该设置这些选项。
# URL presented to clients (e.g. http://example.com:80).
presentation_url=/
# Set this to merge all media_dir base contents into the root container
# (The default is no.)
merge_media_dirs=no

尝试将 umask=007 更改为 umask=002 并重新挂载分区。这样对您有用。
