vi /etc/openstack-dashboard/local_settings 文件中内容如下：

ALLOWED_HOSTS = ['192.168.133.150','192.168.133.1']

#OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = False

OPENSTACK_API_VERSIONS = {
    "identity": 2.0,
    "image": 2,
    "volume": 2,
}


SESSION_ENGINE = 'django.contrib.sessions.backends.cache'


CACHES = {
    'default': {
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
         'LOCATION': 'controller:11211',
    }
}

OPENSTACK_HOST = "controller"
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v2.0" % OPENSTACK_HOST
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"


解决办法：
编辑：/etc/httpd/conf.d/openstack-dashboard.conf
在WSGISocketPrefix run/wsgi下面加一行代码：
WSGIApplicationGroup %{GLOBAL}
保存，重启httpd服务。
