OpenStack-nova组件部署
继之前Placement部署之后，继续部署nova
nova组件部署位置
-
控制节点ct
nova-api（nova主服务）
nova-scheduler（nova调度服务）
nova-conductor（nova数据库服务，提供数据库访问）
nova-novncproxy（nova的vnc服务，提供实例的控制台） -
计算节点c1、c2
nova-compute（nova计算服务）
计算节点Nova服务配置(CT配置)
1. 创建nova数据库，并执行授权操作
[root@ct ~]# mysql -uroot -p

2. 管理Nova用户及服务
- 创建nova用户
[root@ct ~]# openstack user create --domain default --password NOVA_PASS nova
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | 93e904c4063545de83350cd21b7c6b44 |
| name | nova |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
//把nova用户添加到service项目，拥有admin权限
[root@ct ~]# openstack role add --project service --user nova admin
- 创建nova服务
[root@ct ~]# openstack service create --name nova --description "OpenStack Compute" compute
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Compute |
| enabled | True |
| id | 721156ee0ff54b468f8e9ff1b65af18c |
| name | nova |
| type | compute |
+-------------+----------------------------------+
- 给Nova服务关联endpoint（端点）
[root@ct ~]# openstack endpoint create --region RegionOne compute public http://ct:8774/v2.1
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | cb13f505671a453ab7c1be84e8774bfc |
| interface | public |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 721156ee0ff54b468f8e9ff1b65af18c |
| service_name | nova |
| service_type | compute |
| url | http://ct:8774/v2.1 |
+--------------+----------------------------------+
[root@ct ~]# openstack endpoint create --region RegionOne compute internal http://ct:8774/v2.1
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | f769cea83d5343a787203bb5da4de4b0 |
| interface | internal |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 721156ee0ff54b468f8e9ff1b65af18c |
| service_name | nova |
| service_type | compute |
