本文主要是介绍openstack Queens版本在centos7.1，最小化安装(安装nova（控制节点）)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
先在控制节点安装
在数据库中创建nova库和用户并授权
[root@con01~]# mysql -u root -ptest.2018

安装
yum install openstack-nova-api openstack-nova-conductor \
openstack-nova-consoleopenstack-nova-novncproxy \
openstack-nova-scheduleropenstack-nova-placement-api -y
修改配置文件(需要修改的选项较多)
[root@con01 ~]# cat /etc/nova/nova.conf |grep -v ^#

***************************************************************
在/etc/httpd/conf.d/00-nova-placement-api.conf 中添加
<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
***************************************************************
数据库初始化
[root@con01~]# su -s /bin/sh -c "nova-manage api_db sync" nova
会有下面的报错可以忽略
/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:332:NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported exception.NotSupportedWarning
1. # su -s /bin/sh -c "nova-managecell_v2 map_cell0" nova
2. # su -s /bin/sh -c "nova-managecell_v2 create_cell --name=cell1 --verbose" nova
3. # su -s /bin/sh -c "nova-manage dbsync" nova
验证nova cell0和cell1是否正确注册：
启动服务
# systemctl enable openstack-nova-api.service \
openstack-nova-consoleauth.serviceopenstack-nova-scheduler.service \
openstack-nova-conductor.serviceopenstack-nova-novncproxy.service
systemctl restart openstack-nova-api.service \
