在控制節點上，nova-api負責虛擬機生命周期的操作，nova-scheduler實現控制在哪個計算節點上啟動實例，nova-conductor主要是防止云端上計算節點直接訪問數據庫。需要明確的一點是，控制節點上沒有提供計算資源虛擬化功能，都是由計算節點上的nova-compute來完成供給實例計算資源。 1）在controller1上創建nova數據庫 ``` MariaDB [(none)]> CREATE DATABASE nova; MariaDB [(none)]> CREATE DATABASE nova_api; ``` 2）在controller1創建數據庫用戶并賦予權限 ``` MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'yjscloud'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'yjscloud'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'yjscloud'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'yjscloud'; ``` 3）在controller1上創建nova用戶及賦予admin權限 ``` source /root/admin-openrc openstack user create --domain default nova --password yjscloud openstack role add --project service --user nova admin ``` 4）在controller1上創建computer服務 ``` openstack service create --name nova --description "OpenStack Compute" compute ``` 5）在controller1創建nova的endpoint ``` openstack endpoint create --region RegionOne compute public http://yjscloud.com:8774/v2.1/%\(tenant_id\)s openstack endpoint create --region RegionOne compute internal http://yjscloud.com:8774/v2.1/%\(tenant_id\)s openstack endpoint create --region RegionOne compute admin http://yjscloud.com:8774/v2.1/%\(tenant_id\)s ``` 6）在controller1、2、3上安裝nova相關軟件 ``` yum install -y openstack-nova-api openstack-nova-conductor openstack-nova-cert openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler 7）在controller1、2、3上配置nova的配置文件/etc/nova/nova.conf cp /etc/nova/nova.conf /etc/nova/nova.conf.bak >/etc/nova/nova.conf openstack-config --set /etc/nova/nova.conf DEFAULT debug False openstack-config

/etc/nova/nova.conf cinder os_region_name RegionOne ``` ``` scp -p /etc/nova/nova.conf controller2:/etc/nova/nova.conf scp -p /etc/nova/nova.conf controller3:/etc/nova/nova.conf ``` **注意修改ip** 8）在controller1同步nova數據 ``` su -s /bin/sh -c "nova-manage api_db sync" nova su -s /bin/sh -c "nova-manage db sync" nova ``` 9）在controller1上設置開機啟動 ``` systemctl enable openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service ``` controller2、3上設置開機啟動（注意比controller1節點少了`openstack-nova-consoleauth.service`）： ``` systemctl enable openstack-nova-api.service openstack-nova-cert.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service ``` controller1上啟動nova服務： ``` systemctl restart openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service systemctl status openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service ``` controller2、3上啟動nova服務： ``` systemctl restart openstack-nova-api.service openstack-nova-cert.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service systemctl status openstack-nova-api.service openstack-nova-cert.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service systemctl list-unit-files | grep openstack-noca-* ``` 10）隨便一個節點上驗證nova服務 ``` unset OS_TOKEN OS_URL echo "export OS_REGION_NAME=RegionOne" >> admin-openrc source /root/admin-openrc nova service-list openstack endpoint list ```
