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

openstack service create --name nova   --description "Openstack Compute " compute 
openstack endpoint create --region RegionOne compute public   http://192.168.3.220:8774/v2.1

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
