openstack 删除computer node

1、删除的computer节点的虚机

2、删除用户下所有实例

3、nova service-list

nova service-disable uzer-kvm-5 nova-compute

nova service-disable uzer-kvm-6 nova-compute

4、删除数据库对应信息

use nova;

select host from services;

delete from serivces where host="uzer-kvm-5";

delete from serivces where host="uzer-kvm-6";

select host from compute_nodes;

delete from compute_nodes where host="uzer-kvm-5";

delete from compute_nodes where host="uzer-kvm-6";

5、查看是否删除成功

nova service-list
