Nova部署控制節點計算節點配置檔案

  • 控制節點
  • 計算節點
  • 配置檔案
    • 控制節點的/etc/nova/nova.conf檔案
    • 計算節點的/etc/nova/nova.conf檔案

Nova作為計算服務，需要由控制節點統一調配，由計算節點提供服務。是以部署Nova需要在控制節點和計算節點上分别進行操作。

控制節點

進入mariadb，建立Nova的資料庫和使用者

建立資料庫
	create database nova_api;
	create database nova;
	create database nova_cell0;
建立使用者nova并賦予其上述三個庫的所有權限
	grant all privileges on nova_api.* to 'nova'@'%' identified by 'nova';
	grant all privileges on nova.* to 'nova'@'%' identified by 'nova';
	grant all privileges on nova_cell0.* to 'nova'@'%' identified by 'nova';

建立nova和placement的user、service和endpoint

admin登入OpenStack
	source openrc
建立使用者nova
	openstack user create --domain default --password=nova nova
将nova添加為管理者
	openstack role add --project service --user nova admin
建立nova服務
	openstack service create --name nova --description "OpenStack Compute" compute
建立endpoint
	openstack endpoint create --region RegionOne compute public http://controller1:8774/v2.1
	openstack endpoint create --region RegionOne compute internal http://controller1:8774/v2.1
	openstack endpoint create --region RegionOne compute admin http://controller1:8774/v2.1
建立使用者placement
	openstack user create --domain default --password=placement placement
将placement添加為管理者
	openstack role add --project service --user placement admin
建立placement服務
	openstack service create --name placement --description "Placement API" placement
建立endpoint
	openstack endpoint create --region RegionOne placement public http://controller1:8778
	openstack endpoint create --region RegionOne placement internal http://controller1:8778
	openstack endpoint create --region RegionOne placement admin http://controller1:8778
檢查一下上述步驟是否成功：
檢視使用者
	openstack user list
	+----------------------------------+-----------+
	| ID                               | Name      |

	| 6e1f6488725e4c5e85b23b3a089ef36c | placement |
檢視服務
	penstack service list
	| ID                               | Name      | Type      |

如以上均無問題，進入下一步

安裝配置Nova服務

安裝控制節點需要的nova軟體包
	yum -y install openstack-nova-api openstack-nova-conductor openstack-nova-console \
	openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api
編輯配置檔案
	vim /etc/nova/nova.conf
	配置檔案的内容和其含義寫在下面了
修改/etc/httpd/conf.d/00-nova-placement-api.conf
	cat >> /etc/httpd/conf.d/00-nova-placement-api.conf <<EOF
	<Directory /usr/bin>
	   <IfVersion >= 2.4>
	      Require all granted
	   </IfVersion>
	   <IfVersion < 2.4>
	      Order allow,deny
	      Allow from all
	   </IfVersion>
	</Directory>
	EOF
重新開機httpd
	systemctl restart httpd
同步資料庫
	su -s /bin/sh -c "nova-manage api_db sync" nova
	su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
	su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
	su -s /bin/sh -c "nova-manage db sync" nova
檢視nova的cell
	nova-manage cell_v2 list_cells
	+-------+--------------------------------------+
	|  Name |                 UUID                 |
	+-------+--------------------------------------+
	| cell0 | 00000000-0000-0000-0000-000000000000 |
	| cell1 | 046be722-134f-431e-a36c-e27a6700ab69 |

	openstack-nova-conductor openstack-nova-novncproxy
	systemctl restart openstack-nova-api openstack-nova-consoleauth openstack-nova-scheduler \
	openstack-nova-conductor openstack-nova-novncproxy
檢視服務是否啟動
