超详细Openstack核心组件——nova部署

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
Enter password:

Query OK, 0 rows affected (0.000 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.000 sec)

MariaDB [(none)]> exit
Bye

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                             |
