创建数据库ova_api, nova, and nova_cell0 databases:

#  mysql -u root -pChangeme_123

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

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'Changeme_123'; 

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'Changeme_123';

GRANT ALL PRIVILEGES ON nova_placement.* TO 'nova'@'localhost' IDENTIFIED BY 'Changeme_123'; 

GRANT ALL PRIVILEGES ON nova_placement.* TO 'nova'@'%' IDENTIFIED BY 'Changeme_123'; 

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'Changeme_123';

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'Changeme_123';


GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'Changeme_123';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'Changeme_123';

创建用户

#  openstack user create --domain default --password Changeme_123 nova

赋予admin权限

#  openstack role add --project service --user nova admin

这个命令没有回显
创建service

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

创建endpoint

# openstack endpoint create --region RegionOne \
  compute public http://172.16.8.50:8774/v2.1
# openstack endpoint create --region RegionOne \
  compute internal http://172.16.8.50:8774/v2.1
# openstack endpoint create --region RegionOne \
  compute admin http://172.16.8.50:8774/v2.1

创建placement用户

#  openstack user create --domain default --password Changeme_123 placement

赋予admin权限

#  openstack role add --project service --user placement admin

创建服务

#  openstack service create --name placement --description "Placement API" placement

创建endpoint

#  openstack endpoint create --region RegionOne placement public http://172.16.8.50:8778
# openstack endpoint create --region RegionOne placement internal http://172.16.8.50:8778
# openstack endpoint create --region RegionOne placement admin http://172.16.8.50:8778

安装软件包

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

修改配置文件/etc/nova/nova.conf

重启服务

# systemctl restart httpd

验证监听

# ss -tanlp | grep 8778

同步数据库

# 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
# nova-manage cell_v2 list_cells

启动服务并设置开机启动

# 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 \
