十一、Openstack塊存儲服務（cinder）
配置：我在計算點添加了一塊硬碟（sdb）用來當塊存儲用，在我這搭建中控制節點也就是塊存儲節點了
簡單介紹：
cinder主要有四個元件：cinder-api、cinder-volume、cinder-scheduler、cinder-backup
cinder-api：接受API請求，并将其路由到cinder-volume執行
cinder-volume：與塊存儲服務cinder-scheduler的程序進行直接互動
cinder-scheduler：選擇最優存儲提供節點來建立卷
cinder-backup：提供任何種類備份卷到一個備份存儲提供者
後面操作都将在控制節點上
1.進入SQL建立cinder資料庫并授予權限
mysql -uroot -p
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY '123456';
2.建立cinder使用者（需要管理者權限） . admin-openrc
openstack user create --domain default --password-prompt cinder
[[email protected] ~]# . admin-openrc
[[email protected] ~]# openstack user create --domain default --password-prompt cinder
User Password:
Repeat User Password:
+-----------+----------------------------------+
| Field | Value |
+-----------+----------------------------------+
| domain_id | b24b3093654b4ba4be706fe675a03b2d |
| enabled | True |
| id | abf7418a5e90422cab6ae4df523cd850 |
| name | cinder |
+-----------+----------------------------------+
3.添加 admin 角色到 cinder 使用者上
openstack role add --project service --user cinder admin
此操作無傳回
4.建立 cinder 和 cinderv2 服務實體
openstack service create --name cinder --description "OpenStack Block Storage" volume
[[email protected] ~]# openstack service create --name cinder \
> --description "OpenStack Block Storage" volume
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Block Storage |
| enabled | True |
| id | 148fef5f0fae4569b7f7d89d855c7066 |
| name | cinder |
| type | volume |
+-------------+----------------------------------+
openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
[[email protected] ~]# openstack service create --name cinderv2 \
> --description "OpenStack Block Storage" volumev2
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Block Storage |
| enabled | True |
| id | a041d71904364c59a5e65ef49450db70 |
| name | cinderv2 |
| type | volumev2 |
+-------------+----------------------------------+
5. 建立塊裝置存儲服務的 API 入口點 (括号前面有“ \ ”)
openstack endpoint create --region RegionOne volume public http://controller:8776/v1/%\ (tenant_id\ )s
openstack endpoint create --region RegionOne volume internal http://controller:8776/v1/%\ (tenant_id\ )s
openstack endpoint create --region RegionOne volume admin http://controller:8776/v1/%\ (tenant_id\ )s

安裝配置：
1.安裝軟體包
yum install openstack-cinder lvm2 targetcli python-keystone
yum install openstack-cinder lvm2 targetcli python-keystone
2.修改配置檔案/etc/cinder/cinder.conf
vi /etc/cinder/cinder.conf
[DEFAULT]
rpc_backend = rabbit#啟用消息隊列
auth_strategy = keystone#啟用keystone認證
my_ip = 192.168.100.10#控制節點管理接口ip位址
enabled_backends = lvm#啟用 LVM 後端
glance_api_servers = http://controller:9292#配置鏡像api位置
配置資料庫通路
[database]
connection = mysql+pymysql://cinder:[email protected]/cinder
配置消息隊列
[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = 123456
配置認證服務通路
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = 123456
[lvm]（配置檔案中沒有直接添加在最後，不放心自己看看）
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver#配置LVM後端以LVM驅動結束
volume_group = cinder-volumes#卷組
iscsi_protocol = iscsi#配置iSCSI服務
iscsi_helper = lioadm#配置iSCSI服務
配置鎖路徑
[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
3.初始化塊裝置服務的資料庫
su -s /bin/sh -c "cinder-manage db sync" cinder
[[email protected] ~]# su -s /bin/sh -c "cinder-manage db sync" cinder
Option "logdir" from group "DEFAULT" is deprecated. Use option "log-dir" from group "DEFAULT".

4.建立LVM 實體卷 /dev/sdb
pvcreate /dev/sdb
[[email protected] ~]# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created
vgcreate cinder-volumes /dev/sdb
[[email protected] ~]# vgcreate cinder-volumes /dev/sdb
Volume group "cinder-volumes" successfully created
5.修改配置檔案/etc/lvm/lvm.conf
vi /etc/lvm/lvm.conf
找到添加一個過濾器
devices {
filter = [ "a/sdb/", "r/.*/"]
}
完成安裝：
控制節點上啟動：
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service openstack-cinder-volume.service target.service lvm2-lvmetad.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service openstack-cinder-volume.service target.service lvm2-lvmetad.service
[[email protected] ~]# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service openstack-cinder-volume.service target.service lvm2-lvmetad.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-api.service to /usr/lib/systemd/system/openstack-cinder-api.service.

[[email protected] ~]# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service openstack-cinder-volume.service target.service lvm2-lvmetad.service
計算節點修改配置檔案/etc/nova/nova.conf
vi /etc/nova/nova.conf
配置計算節點使用塊裝置存儲
[cinder]
os_region_name = RegionOne
重新開機計算API
systemctl restart openstack-nova-api.service
驗證：
1.擷取管理者權限
. admin-openrc
2.列出服務元件以驗證是否每個程序都成功啟動
cinder service-list
[[email protected] ~]# . admin-openrc
[[email protected] ~]# cinder service-list

添加一塊雲盤：
1.登陸管理者賬号——選擇計算——卷——建立雲硬碟
2.建立雲硬碟
建立完成
3.選擇編輯雲硬碟———管理連接配接
4.使雲硬碟連接配接到雲主機
完成
5.虛拟機控制台檢視挂載的盤
你會發現多了一塊盤叫vdb
