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:

- 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：
[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage api_db sync" nova
[root@linux-node1 ~]#
- 登记cell0数据库
[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
[root@linux-node1 ~]#
- 创建cell1
[root@linux-node1 ~]# nova-manage cell_v2 list_cells
