openstack mitaka版本使用

1. 修改管理员密码

默认账户default ---admin---ADMIN_PASS
[root@controller ~]# vim /root/admin-openrc 
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=123456 修改此项
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

source /root/admin-openrc   不然控制节点无法查看运行状态

2. 想新建虚拟实例在指定的宿主机上

3.新建普通用户有删除创建实例的权限

4. 新建项目创建配额限制普通用户创建实例

5. glance 镜像服务迁移出来

controller 停掉glance服务
[root@controller ~]# systemctl stop openstack-glance-api.service openstack-glance-registry.service 
[root@controller ~]# systemctl disable openstack-glance-api.service openstack-glance-registry.service 
Removed symlink /etc/systemd/system/multi-user.target.wants/openstack-glance-api.service.

9. 虚拟机冷迁移

1：开启nova计算节点之间互信
冷迁移需要nova计算节点之间使用nova用户互相免密码访问
默认nova用户禁止登陆，开启所有计算节点的nova用户登录shell。

usermod -s /bin/bash nova
su - nova
ssh-keygen -t rsa
#生成密钥
cp -fa .ssh/id_rsa.pub .sshauthorized_keys

将公钥发送给其他计算节点的nova用户的/var/lib/nova/.ssh目录下，注意权限和所属组
[nova@compute1 ~]$ scp -rp .ssh root@10.0.0.33:`pwd`
[root@compute3 ~]# chown -R nova:nova /var/lib/nova/.ssh/

2：修改控制节点nova.conf
vim /etc/nova/nova.conf
[DEFAULT]
scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,DiskFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter

重启openstack-nova-scheduler
systemctl restart openstack-nova-scheduler.service

3:修改所有计算节点的nova配置
vi /etc/nova/nova.conf
[DEFAULT]
allow_resize_to_same_host = True

重启openstack-nova-compute
systemctl restart openstack-nova-compute.service

4：dashboard上进行操作---->创建实例---->实现冷迁移操作
