Parallels CentOS 上的 Apache 无法读取 OSX 主机文件

Parallels CentOS 上的 Apache 无法读取 OSX 主机文件

Parallels虚拟服务器是CentOS 5.5，主机系统是OSX Snow Leopard

在 CentOS 中，主机文件系统被挂载：

none          /media/psf   prl_fs   sync,nosuid,nodev,noatime,share     0       0

Apache 在 CentOS 中运行，并具有指向主机文件系统的以下别名

Alias /ca_media /home/django/soft-link-via-media-psf/media
<Location "/ca_media">
    SetHandler None
    ExpiresActive on
    ExpiresDefault "access plus 1 week"
    FileETag MTime Size
</Location>

这时就变得很奇怪了，下面是主机的演示。似乎有些文件无法被提供 - 但其他文件可以。我看不出两者有什么区别（请注意，“pgevr”是我在 中配置的 CentOS 机器的名称/etc/hosts）：

~/Projects/er_trunk/media/er/js$ ls -l navagation_menu.js 
-rw-r--r--  1 millere  staff  702 Sep 21  2009 navagation_menu.js
~/Projects/er_trunk/media/er/js$ curl http://pgevr/ca_media/er/js/navagation_menu.js
curl: (18) transfer closed with 702 bytes remaining to read
~/Projects/er_trunk/media/er/js$ echo 'foo' > bar.js
~/Projects/er_trunk/media/er/js$ curl http://pgevr/ca_media/er/js/bar.js
foo
~/Projects/er_trunk/media/er/js$ ls -l bar.js 
-rw-r--r--  1 millere  staff  4 Oct 21 11:51 bar.js
~/Projects/er_trunk/media/er/js$ file navagation_menu.js 
navagation_menu.js: ASCII text
~/Projects/er_trunk/media/er/js$ file bar.js 
bar.js: ASCII text
~/Projects/er_trunk/media/er/js$ cp navagation_menu.js bar.js 
~/Projects/er_trunk/media/er/js$ curl http://pgevr/ca_media/er/js/bar.js
curl: (18) transfer closed with 702 bytes remaining to read

这是与两个文件系统有关的问题，还是与挂载的文件系统类型有关的问题？您将如何调查此问题？

[编辑..这是使用--trace-ascii的失败的curl请求的结果]

答案1

我遇到了同样的问题，并且取消注释 /etc/httpd/conf/httpd.conf 中的 EnableSendfile Off 对我有用（如 Deutch 在上面的帖子中所建议的那样）。
