之(五) Horizon安裝

手動安裝Openstack Mikita的第五部分: 用戶界面Horizon安裝.

這部分內容主要是對OpenStack Installation Guide for Red Hat Enterprise Linux and CentOS在Horizon這部分內容的實踐總結.

Dashboard依賴於幾個openstack的核心服務: Identity(Keystone), Image(Glance), Compute(Nove)以及網絡服務. 其中網絡服務可以由Neutron或者Nova-network提供. 一些獨立的服務, 如Object Storage無法使用Dashboard.

我們在controller節點上部署Horizon服務.

1. 安裝Horizon

[root@controller ~]# yum install openstack-dashboard -y

2. 配置Horizon

編輯 /etc/openstack-dashboard/local_settings 文件:

OPENSTACK_HOST = "controller"
ALLOWED_HOSTS = ['*', ]
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"

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

3. Restart the web server and session storage service

[root@controller ~]# systemctl restart httpd.service memcached.service

4. 驗證

訪問http://10.0.0.11/dashboard
