提问by kjr1995
I am running Raspbian version 7 on my raspberry pi. I am running owncloud on this. I have mounted an external drive under /media/Owncloud. This is where I have owncloud store all the files. I cannot access this directory. When I try cd /media/Owncloudit gives me the following error:-bash: cd: /media/Owncloud/: Permission denied
How can I access this directory?
我在我的树莓派上运行 Raspbian 版本 7。我正在运行owncloud。我已经在 /media/Owncloud 下安装了一个外部驱动器。这是我拥有自己的云存储所有文件的地方。我无法访问此目录。当我尝试时，cd /media/Owncloud它给了我以下错误：-bash: cd: /media/Owncloud/: Permission denied
如何访问此目录？

OwnCloud and external hard drives are tricky and you have a permission issue. For some reason, trying to make a link to an external hard drive has issues, so you need to try mounting your external hard drive.
OwnCloud 和外部硬盘驱动器很棘手，您有权限问题。出于某种原因，尝试链接到外部硬盘驱动器会出现问题，因此您需要尝试安装外部硬盘驱动器。
External hard drive - Apply the proper group and read permissions:
外置硬盘 - 应用正确的组和读取权限：
chown -R www-data:www-data /media/user/your_hard_drive/owncloud_data/
chmod -R 777 /media/user/your_hard_drive/owncloud_data/
Local hard drive - Apply the proper group and read permissions:
本地硬盘 - 应用正确的组和读取权限：
mkdir /var/www/owncloud/data
chown -R www-data:www-data /var/www/owncloud/data
chmod -R 777 /var/www/owncloud/data
Make the mount of local hard drive to external hard drive
将本地硬盘挂载到外置硬盘
mount --bind /media/user/your_hard_drive/owncloud_data/ /var/www/owncloud/data/

If you just want to cdinto the directory, change to root with sudo -i.
如果您只想cd进入目录，请使用sudo -i.

The issue is with wrong permissions.
问题是权限错误。
If the webserver runs as user www-data, the mounted folder must be somehow accessible to that user
如果网络服务器以用户 www-data 的身份运行，则该用户必须以某种方式访问安装的文件夹
either that user must be owner of mounted folder and its contents, and have the "user" permissions, or
the the folder must be accessible to the group the webserver user is in (usually www-data).
该用户必须是已安装文件夹及其内容的所有者，并且具有“用户”权限，或者
Web 服务器用户所在的组（通常是 www-data）必须可以访问该文件夹。
To see the current permissions use the ls -lcommand.
要查看当前权限，请使用该ls -l命令。
To change the owner use chowncommand,
要更改所有者使用chown命令，
to change the permissions for the user-owner, and group-owner, use the chmodcommand,
要更改用户所有者和组所有者的权限，请使用chmod命令，
or just use Midnight commander (mc) or some GUI to do that.
或者只是使用午夜指挥官 ( mc) 或一些 GUI 来做到这一点。
If you are mounting the external volume through /etc/fstabcheck the options in there. I would not recommend using the volume with some dynamic mounting (like the file managers do (gvfs-fuse)) if is a key folder for a webserver with ownCloud and you need to have it auto-mounted on boot, as some specific user that the webserver is run as.
如果您通过/etc/fstab检查那里的选项安装外部卷。如果是带有 ownCloud 的网络服务器的关键文件夹，并且您需要在启动时自动安装它，作为某些特定用户网络服务器运行为。
I have an experience with having the ownCloud data folder on /srv/data(also ownCloud 7.0 on Ubuntu Server 14.04 VPS), the permissions are 770 and the owner is www-data:www-data, and in the ownCloud config file, I use the line
我有使用 ownCloud 数据文件夹的经验/srv/data（Ubuntu Server 14.04 VPS 上的 ownCloud 7.0），权限为 770，所有者为 www-data:www-data，在 ownCloud 配置文件中，我使用了该行
'datadirectory' => '/srv/data',
'datadirectory' => '/srv/data',
I would not recommend using 777 permissions, as it is not a good security practice in general.
我不建议使用 777 权限，因为这通常不是一个好的安全实践。

In order to access /media/Owncloud, you need to set the proper permissions. Run the command sudo chmod 755 /media/Owncloud(for more security relative to permission 777).
为了访问/media/Owncloud，您需要设置适当的权限。运行命令sudo chmod 755 /media/Owncloud（为了获得相对于权限 777 的更多安全性）。
You also may need to allow to webserver to access the directory. In order to do that, run sudo chown -R www-data:www-data /media/Owncloud
您可能还需要允许网络服务器访问该目录。为了做到这一点，运行sudo chown -R www-data:www-data /media/Owncloud
