Ubuntu-16.04 部署 OpenStack Ocata<下>
六、配置 Dashboard 仪表盘服务(Controller Node)
1.配置Dashboard
1 # apt -y install openstack-dashboard 2 # vim /etc/openstack-dashboard/local_settings.py 3 OPENSTACK_HOST = "192.168.30.145" ##配置仪表盘以使用 OpenStack 服务 4 ALLOWED_HOSTS = ['*'] ##允许所有主机访问仪表板 5 ##配置 memcached 会话存储服务 6 SESSION_ENGINE = 'django.contrib.sessions.backends.cache' 7 CACHES = { 8 'default': { 9 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 10 'LOCATION': '192.168.30.145:11211', 11 } 12 } 13 OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST ##启用第3版认证API 14 OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True ##启用对域的支持 15 OPENSTACK_API_VERSIONS = { 16 "identity": 3, 17 "image": 2, 18 "volume": 2, 19 } ##配置API版本 20 OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "default" ##通过仪表盘创建用户时的默认域配置 21 OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user" ##通过仪表盘创建的用户默认角色配置 22 TIME_ZONE = "Asia/Chongqing" ##配置时区 23 24 # cat /etc/openstack-dashboard/local_settings.py|grep -v "#"|grep -v ^$
2.更改 dashboard 密钥文件权限
1 # chown www-data:www-data /var/lib/openstack-dashboard/secret_key 2 # service apache2 reload ##重新加载 web 服务器配置
3.验证仪表盘服务
浏览器输入 http://controller/horizon 访问仪表盘。
使用 admin 或者 demo 用户凭证和 default 域凭证验证。
身份管理-项目
身份管理-用户
七、启动一个实例
1.创建公共网络
a.获取 admin 权限
1 # . admin-openrc
b.创建网络
1 # openstack network create --share \\ 2 --provider-physical-network provider \\ 3 --provider-network-type flat provider 4 +---------------------------+--------------------------------------+ 5 | Field | Value | 6 +---------------------------+--------------------------------------+ 7 | admin_state_up | UP | 8 | availability_zone_hints | | 9 | availability_zones | | 10 | created_at | 2017-03-29T11:59:09Z | 11 | description | | 12 | dns_domain | None | 13 | id | ff30780d-45af-45dc-860f-59b1c091c2a2 | 14 | ipv4_address_scope | None | 15 | ipv6_address_scope | None | 16 | is_default | None | 17 | mtu | 1500 | 18 | name | provider | 19 | port_security_enabled | True | 20 | project_id | 2461396f6a344c21a2360a612d4f6abe | 21 | provider:network_type | flat | 22 | provider:physical_network | provider | 23 | provider:segmentation_id | None | 24 | qos_policy_id | None | 25 | revision_number | 3 | 26 | router:external | Internal | 27 | segments | None | 28 | shared | True | 29 | status | ACTIVE | 30 | subnets | | 31 | updated_at | 2017-03-29T11:59:10Z | 32 +---------------------------+--------------------------------------+
--shared:允许所有项目使用虚拟网络
--provider:管理员创建的直接和物理网络映射的网络
--provider-physical-network (物理网络的逻辑名称)
--provider-network-type (网络类型，包括 vxlan, gre, vlan, flat, local)
c.配置 Modular Layer 2 (ML2) 插件
|
