1.8 主机聚合
通过创建主机聚合可以让新创建的实例指定的调度到聚合组中的计算节点中去。
2.项目用户角色的关系
openstack 中只有两个角色
- admin - user一个项目有多个成员用户，user 角色用户只能管理所在项目组中的虚拟资源，能够创建配额内的计算资源，而且不能看到其它非授权项目的资源。在管理菜单中只有项目选项卡。无法对虚拟机进行迁移。
admin 角色能够给相应的项目配额，防止user角色对资源的过度使用。在菜单栏中有管理员选项卡，在管理员中可以看到所有的计算资源，但是该用户项目选项卡中不能看到其它项目的资源。
3.glance 服务迁移
3.1 停止原有服务
glance-api glance-registry
3.2 在新主机上安装数据库
yum -y install mariadb-server mariadb python2-PyMySQL
vi /etc/my.cnf
[mysqld]
bind-address = 10.0.0.32
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_gene
# 初始化数据库
mysql_secure_installation
## 设置数据库密码
Set root password? [Y/n] y
New password: # <===== openstack
Re-enter new password:
Password updated successfully!
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y
3.3 恢复glance数据库数据
# 导出原glance数据库
mysqldump -uroot -p -B glance > glance.sql
scp glance.sql root@compute2:~
# 新机器导入数据库
mysql -uroot -p < glance.sql
[root@compute2 ~]# mysql glance -uroot -p -e 'show tables;'
Enter password:

# 创建glance用户
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'GLANCE_DBPASS';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'GLANCE_DBPASS';
3.4 安装配置glance
yum -y install openstack-glance.noarch
scp controller:/etc/glance/glance-api.conf /etc/glance/
scp controller:/etc/glance/glance-registry.conf /etc/glance/
# 只需要更改数据库连接即可
vi /etc/glance/glance-api.conf
......
[database]
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
......
vi /etc/glance/glance-registry.conf
......
connection = mysql+pymysql://glance:GLANCE_DBPASS@compute2/glance
......
# 启动服务
systemctl start openstack-glance-api.service openstack-glance-registry.service
systemctl enable openstack-glance-api.service openstack-glance-registry.service
3.5 镜像文件迁移
-p 保持文件属性
scp -p root@10.0.0.11:/var/lib/glance/images/* /var/lib/glance/images/
chown -R glance.glance glance/
3.6 注册新的服务目录
a. 方法一：命令更改
# 查看现有glance endpoint
openstack endpoint list|grep glance
# 删除
openstack endpoint delete 2879c39c7dc64db8a5f82d479b6d2f08
# 后面的是ID 用上面的命令查询出来的
#注册新的glance endpoint
[root@controller ~]# openstack endpoint create --region RegionOne image public http://compute2:9292

+--------------+----------------------------------+
b.方法二：直接修改数据库
keystone库 endpoin表中记录了
%s###gc
c # 交换式替换
% # 全局
3.7 更改控制节点和计算节点配置文件glance-api地址
- 涉及配置文件nova-api
yum -y install openstack-utils
openstack-config --set /etc/nova/nova.conf glance api_servers http://compute2:9292
# 重启服务
## 控制节点
openstack-nova-api
## 计算节点
openstack-nova-compute
3.8 验证
4.cinder 块存储服务
控制节点操作
cinder-api: 接收和响应外部有关块存储请求
cinder-volume： 提供存储空间,与其它存储对接，比如ceph
cinder-scheduler：调度器，决定将要分配的空间由哪一个cinder-volume提供，选择最优存储提供节点来创建卷。
cinder-backup： 备份存储
块存储服务（cinder）为实例提供块存储。存储的分配和消耗是由块存储驱动器，或者多后端配置的驱动器决定的。还有很多驱动程序可用：NAS/SAN，NFS，ISCSI，Ceph等。
典型情况下，块服务API和调度器服务运行在控制节点上。取决于使用的驱动，卷服务器可以运行在控制节点、计算节点或单独的存储节点。
4.1 创建数据库
mysql -u root -p
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CINDER_DBPASS';

4.4 配置控制节点nova-api
vi /etc/nova/nova.conf
[cinder]
os_region_name = RegionOne
# 重启服务
systemctl restart openstack-nova-api.service
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
4.5 配置一个存储节点
可以选择任意一台主机
注意节点的hosts 文件和yum私有源
a.安装lvm
yum install lvm2 -y
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service
b.配置lvm
# 添加新的磁盘，这种方式后可以不重启虚拟机添加硬盘
echo '- - -' >/sys/class/scsi_host/host0/scan
echo '- - -' >/sys/class/scsi_host/host1/scan
echo '- - -' >/sys/class/scsi_host/host2/scan

vi /etc/lvm/lvm.conf

# 这里表示只允许sda、sdc做lvm的操作。

只有实例可以访问块存储卷组。不过，底层的操作系统管理这些设备并将其与卷关联。默认情况下，LVM卷扫描工具会扫描
/dev目录，查找包含卷的块存储设备。如果项目在他们的卷上使用LVM，扫描工具检测到这些卷时会尝试缓存它们，可能会在底层操作系统和项目卷上产生各种问题。您必须重新配置LVM，让它只扫描包含cinder-volume卷组的设备。编辑/etc/lvm/lvm.conf
4.6 部署cinder组件
这里在存储节点部署的存储组件可以与控制节点的通信。
配置文件版本1:

配置文件版本2:
因为版本1配置根据官方配置第一次运行完全没有问题，但是在虚拟机挂起一次然后再启动的时候就开始报错。

4.7 启动服务
systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service
4.8 验证
多出了卷的选项。
a.创建卷
4.9 创建卷类型
通过创建卷类型可以让创建卷的时候指定选用哪种存储方式的的卷。
绑定真实属性
这里的键值对与enabled_backends = ssd,hdd是相对应的。这样可以控制创建的卷在哪个vg中。
