###openstack-ocata 單節點安裝 部署 目錄彙總

一 安裝資料庫服務

mysql -u root -p

CREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
--------------------------------------------------------------------------------

二 安裝nova使用者，角色等
.adminrc
openstack user create --domain default --password-prompt nova
openstack role add --project service --user nova admin

openstack service create --name nova --description "OpenStack Compute" compute

openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1

openstack user create --domain default --password-prompt placement

openstack role add --project service --user placement admin
openstack service create --name placement --description "Placement API" placement
openstack endpoint create --region RegionOne placement public http://controller:8778
openstack endpoint create --region RegionOne placement internal http://controller:8778
openstack endpoint create --region RegionOne placement admin http://controller:8778

--------------------------------------------------------------------------------

三 安裝nova軟體包

yum install openstack-nova-api openstack-nova-conductor \
openstack-nova-console openstack-nova-novncproxy \
openstack-nova-scheduler openstack-nova-placement-api -y

--------------------------------------------------------------------------------
四 配置nova檔案

cp /etc/nova/nova.conf /etc/nova/nova.conf.bak
>/etc/nova/nova.conf

echo '

五 啟動服務

systemctl restart httpd.service
systemctl status httpd.service

--------------------------------------------------------------------------------

六 初始化資料庫

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

--------------------------------------------------------------------------------

七 驗證是否正確註冊

nova-manage cell_v2 list_cells

--------------------------------------------------------------------------------
八 啟動nova服務
systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
systemctl restart openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
