Apache 无法显示/跟踪符号链接

Question

我在运行 OS X 10.10 的办公室 Mac mini 上运行 apache v2.4 来托管个人网站。基本网站运行良好，但当我将符号链接添加到目录（在 ~/anil/Documents/ 文件夹中）时，它会抛出 403 禁止访问错误。

我已经在 /etc/apache2/httpd.conf 上启用了 FollowSymLinks，如下所示

DocumentRoot "/Users/anil/Sites"
<Directory "/Users/anil/Sites">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.4/mod/core.html#options
    # for more information.
    #
    Options All MultiViews
    MultiviewsMatch Any

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   AllowOverride FileInfo AuthConfig Limit
    #
    AllowOverride All

    #
    # Controls who can get stuff from this server.
    #
    Require all granted
</Directory>

这是我的 /etc/apache2/users/anil.conf

<Directory "/Users/anil/Sites/">
    AddLanguage en .en
    LanguagePriority en fr de
    ForceLanguagePriority Fallback
    Options Indexes MultiViews FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from localhost
    Require all granted
</Directory>

我还验证了符号链接目标目录中的所有目录都具有执行权限，但无济于事；为了尝试排除这个问题，我在站点 rootdir 中下一级目录中为虚拟文件创建了一个符号链接，但仍然出现同样的错误。

$ ls -lrt
total 24
-rw-r--r--+ 1 anil  staff   49 Feb 24 08:15 somefile
lrwxr-xr-x  1 anil  staff   29 Feb 24 09:13 Corpus -> /Users/anil/Documents/Corpus
drwxr-xr-x  3 anil  staff  102 Feb 25 07:37 tmp_folder
lrwxr-xr-x  1 anil  staff   20 Feb 25 07:38 blankfile -> tmp_folder/blankfile

以下是 apache 的 error_log 的相关输出：
