初始化api数据库
su -s /bin/sh -c "nova-manage api_db sync" nova
注册cell0
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
添加cell1
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
初始化nova数据库
su -s /bin/sh -c "nova-manage db sync" nova
查看注册cells
nova-manage cell_v2 list_cells
查看数据库表
mysql -unova -pnova -e " use nova;show tables;use nova_api;show tables;use nova_cell0;show tables;"
启动并配置开机启动
systemctl restart openstack-nova-scheduler openstack-nova-conductor openstack-nova-novncproxy openstack-nova-api openstack-nova-console openstack-nova-scheduler
systemctl enable openstack-nova-api openstack-nova-scheduler openstack-nova-conductor openstack-nova-novncproxy openstack-nova-console 1>&2
配置服务与端点

控制节点上加入主机
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
查看主机
openstack host list
openstack compute service list
openstack catalog list
