安裝配置openstack-dashboard（horizon）

這里把dashboard安裝在controller節點上。

1、安裝程序包

# yum install -y openstack-dashboard

2、修改配置文件

# vim /etc/openstack-dashboard/local_settings

OPENSTACK_HOST = "controller"
ALLOWED_HOSTS = ['*', ]         #注意這里的寫法！

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

Enable the Identity API version 3:
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

OPENSTACK_API_VERSIONS = {
    "identity": 3,
    "image": 2,
    "volume": 2,
}

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

configure the time zone:
TIME_ZONE = "Asia/Shanghai"

3、重啟httpd和memcached服務

# systemctl restart httpd.service memcached.service

4、驗證

用瀏覽器訪問 http://controller/dashboard

使用admin賬號或demo賬號登錄。
