六、【openstack train安装】第五步-安装nova

目前所有教程都是在控制节点进行的，控制节点组件部署介绍完之后会介绍计算节点。

初学者可以从手动部署开始了解各组件的工作内容和工作原理。

后面会出openstack自动化部署的教程。

1、安装软件包和配置

先创建计算服务用户，记住密码，本次使用123456

[root@controller ~]# openstack user create --domain default --password-prompt nova

[root@controller ~]# openstack role add --project service --user nova admin

[root@controller ~]# openstack service create --name nova   --description "OpenStack Compute" compute

[root@controller ~]# openstack endpoint create --region RegionOne   compute public http://controller:8774/v2.1

[root@controller ~]# openstack endpoint create --region RegionOne   compute internal http://controller:8774/v2.1

[root@controller ~]# openstack endpoint create --region RegionOne   compute admin http://controller:8774/v2.1

[root@controller ~]# yum install openstack-nova-api openstack-nova-conductor   openstack-nova-novncproxy openstack-nova-scheduler -y

[root@controller ~]# vi /etc/nova/nova.conf

[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova

[root@controller ~]# systemctl enable     openstack-nova-api.service     openstack-nova-scheduler.service     openstack-nova-conductor.service     openstack-nova-novncproxy.service

[root@controller ~]# systemctl start     openstack-nova-api.service     openstack-nova-scheduler.service     openstack-nova-conductor.service     openstack-nova-novncproxy.service

2、验证

[root@controller ~]# openstack compute service list

[root@controller ~]# openstack catalog list

[root@controller ~]# openstack image list

[root@controller ~]# nova-status upgrade check

这个输出的每项状态都是success
