修改placement配置

vim /etc/httpd/conf.d/00-nova-placement-api.conf

在前插入以下内容

= 2.4> Require all granted Order allow,deny Allow from all

启动placement

systemctl restart httpd

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

验证

nova-manage cell_v2 list_cells

启动服务

systemctl start openstack-nova-api.service \
openstack-nova-consoleauth.service openstack-nova-scheduler.service \
openstack-nova-conductor.service openstack-nova-novncproxy.service
systemctl enable openstack-nova-api.service \
