openstack云主机 跨项目迁移

1、面板或者后台修改网络类型为共享网络

openstack network set xxxxxxx --share

2、备份数据库

docker exec -it -u root mariadb mysqldump -uroot -pxxxxxxxxxxx nova instances  > nova_instances.sql

docker exec -it -u root mariadb mysqldump -uroot -pxxxxxxxxxxx nova instance_info_caches > nova_instance_info_caches.sql

docker exec -it -u root mariadb mysqldump -uroot -pxxxxxxxxxxx cinder volumes > cinder_volumes.sql

docker exec -it -u root mariadb mysqldump -uroot -pxxxxxxxxxxx neutron ports > neutron_ports.sql

3、查找原来项目的user_id和project_id，并记录下来

openstack user list  --long
openstack project list --long

4、查找目标项目的user_id和project_id

openstack user list  --long
openstack project list --long

5、修改数据库

mysql> update nova.instances set user_id="xxxxxxx",project_id="xxxxxxxx" where project_id="XXXXXXX";
mysql> update cidner.volumes set user_id="xxxxxxx",project_id="xxxxxxxx" where project_id="XXXXXXX";
mysql> update neutron.ports set user_id="xxxxxxx",project_id="xxxxxxxx" where project_id="XXXXXXX";

6、将导出来的nova.instance_info_caches.sql导出来，进行修改替换project_id 为目标项目id。

//将数据库表导入
docker cp nova_instance_info_caches.sql mariadb:/opt/
mysql> use nova;
mysql[nova]>source /opt/nova_instance_info_caches.sql

6、面板上验证云主机是否迁移成功
