上一篇介绍了glance，并且成功创建了一个镜像，这一篇介绍Nova。
- 首先创建Nova用户，需要记得先source环境变量，然后创建Nova用户，并设置密码为nova
[root@linux-node1 ~]# source admin-openstack.sh [root@linux-node1 ~]# openstack user create --domain default --password-prompt nova User Password: Repeat User Password: +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 34c7be4d612a45b4830304af29eb010e | | name | nova | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+
- 给Nova用户添加admin角色
[root@linux-node1 ~]# openstack role add --project service --user nova admin
[root@linux-node1 ~]#
- 创建Nova服务实例
[root@linux-node1 ~]# openstack service create --name nova > --description "OpenStack Compute" compute +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Compute | | enabled | True | | id | bf254b3182e04256897e925632f171d0 | | name | nova | | type | compute | +-------------+----------------------------------+
- 创建NovaAPI服务端点
[root@linux-node1 ~]# openstack endpoint create --region RegionOne > compute public http://192.168.56.11:8774/v2.1 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 06541267fb014c7f9b0be6748366fdba | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | bf254b3182e04256897e925632f171d0 | | service_name | nova | | service_type | compute | | url | http://192.168.56.11:8774/v2.1 | +--------------+----------------------------------+ [root@linux-node1 ~]# openstack endpoint create --region RegionOne > compute internal http://192.168.56.11:8774/v2.1 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | d9da327e665645fb9766dea107e13bf1 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | bf254b3182e04256897e925632f171d0 | | service_name | nova | | service_type | compute | | url | http://192.168.56.11:8774/v2.1 | +--------------+----------------------------------+ [root@linux-node1 ~]# openstack endpoint create --region RegionOne > compute admin http://192.168.56.11:8774/v2.1 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 805cd45ded6841d0acd3335ccfdc29ef | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | bf254b3182e04256897e925632f171d0 | | service_name | nova | | service_type | compute | | url | http://192.168.56.11:8774/v2.1 | +--------------+----------------------------------+
- 创建placement服务，并将密码设置为placement
[root@linux-node1 ~]# openstack user create --domain default --password-prompt placement User Password: Repeat User Password: +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 27080769990347169fdc6bf81fe9ebd1 | | name | placement | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+
- 给placement用户添加admin角色
[root@linux-node1 ~]# openstack role add --project service --user placement
admin
- 在服务目录中创建placement API实例
[root@linux-node1 ~]# openstack service create --name placement --description "Placement API" placement +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | Placement API | | enabled | True | | id | 344d25c79f1b412cb0c5958bd8242b2c | | name | placement | | type | placement | +-------------+----------------------------------+

- 因为一个packaging bug，必须通过在/etc/httpd/conf.d/00-nova-placement-api.conf添加如下配置来是能placement API的接入：
<Directory /usr/bin> <IfVersion >= 2.4> Require all granted </IfVersion> <IfVersion < 2.4> Order allow,deny Allow from all </IfVersion> </Directory>
- 重启httpd服务
# systemctl restart httpd
- 同步nova-api数据库：
