deshborad登陆报错404

搭建devstack环境，OK后登陆页面，出现错误信息如下：

Page not found (404)

Request Method:  GET

Request URL:  http://192.168.8.127/dashboard/

Using the URLconf defined in openstack_dashboard.urls, Django tried these URL patterns, in this order:

    ^$ [name='splash']

    ^auth/

    ^home/$ [name='user_home']

    ^i18n/js/(?P<packages>\S+?)/$ [name='jsi18n']

    ^i18n/setlang/$ [name='set_language']

    ^i18n/

    ^qunit/$ [name='qunit_tests']

    ^project/

    ^admin/

    ^settings/

    ^static\/(?P<path>.*)$

    ^media\/(?P<path>.*)$

    ^500/$

The current URL, dashboard/, didn't match any of these.

之前遇到过N多登陆的问题，很快就解决了。信心满满的，结果捣腾了一会儿都不见效。

查看页面/var/log/httpd/horizon_error.log日志，有如下错误

[Fri Jan 24 06:41:37 2014] [error] Not Found: /dashboard/

在FireFox上输入http://192.168.8.127/，回车后自动变为http://192.168.8.127/dashboard/

使用http://192.168.8.127/admin/ 登陆成功。。。
