二、错误记录：
1、dashboard报各种错误，如无法获取扩展。

# openstack catalog list（查看各个服务的endpoint）
错误如下：
| nova   | compute  |                                                             |
| nova  | compute   |                                                             |
| nova  | compute   | RegionOne                                          |
|           |                  |   admin: http://controller:8774/v2.1     |
|           |                  | RegionOne                                          |
|           |                  |  internal: http://controller:8774/v2.1     |
|           |                  | RegionOne                                          |
|           |                  |   public: http://controller:8774/v2.1

解决：进入msyql数据库，把keystone库的service表的compute多余记录删除
msyql> delete from service  where id='bdbedb443b9646938f1526aa990e09b0';（删除记录）
#systemctl restart openstack-nova-api.service openstack-nova-scheduler.service  openstack-nova-conductor.service  openstack-nova-novncproxy.service

一定要重启Nova服务，修改后

2、MariaDB [keystone]> delete from service where type='volumev2';
报错：ERROR 1451 (23000): Cannot delete or update a parent row: a foreign key constraint fails (`keystone`.`endpoint`, CONSTRAINT `endpoint_service_id_fkey` FOREIGN KEY (`service_id`) REFERENCES `service` (`id`))

MariaDB [keystone]> SET FOREIGN_KEY_CHECKS = 0;
Query OK, 0 rows affected (0.001 sec)

MariaDB [keystone]> delete from service  where type='volumev2';
Query OK, 1 row affected (0.001 sec)

MariaDB [keystone]> SET FOREIGN_KEY_CHECKS = 1;
Query OK, 0 rows affected (0.000 sec)

3、新建的虚拟机没法从远程控制台启动

解决：修改nova的配置文件

# openstack-config --set /etc/nova/nova.conf libvirt virt_type  qemu  （kvm格式在vm虚拟机上不上很友好）
# openstack-config --set /etc/nova/nova.conf libvirt cpu_mode  none
# systemctl restart openstack-nova-compute.service

4、卷的状态不可用（下图为修改后）

解决方法：

#vim /etc/cinder/cinder.conf

auth_uri = http://[keystone IP]:5000
auth_url = http://[keystone IP]:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = services
username = cinder
password = [cinder's password]
#根据自己的实际情况替换（cinder节点）

三、常用命令：

1、# nova service-list （查看nova服务状态）

2、 # nova-manage version （查看openstack的版本号，19为stein版）
19.1.0-1.el7

3、上传镜像：

# openstack image create "centos7"   （此处粘贴复制不好使）
> --file CentOS-7.6-x86_64-GenericCloud.qcow2 
>  --disk-format qcow2 --container-format bare 
>  --public

4、# openstack image list （列出当前所有的镜像）

5、# openstack volume list （列出卷）

# openstack volume delete 4e131e71-70dd-40ba-98d7-4a103279a1db （删除卷）

6、# openstack network agent list （列出网络状态）
