9.0.Cinder概述

OpenStack塊存儲服務(cinder)爲虛擬機添加持久的存儲，塊存儲提供一個基礎設施爲了管理卷，以及和OpenStack計算服務交互，爲實例提供卷。此服務也會激活管理卷的快照和卷類型的功能。正則表達式

塊存儲服務一般包含下列組件：redis

1）cinder-api
接受API請求，並將其路由到``cinder-volume``執行。
2）cinder-volume
與塊存儲服務和例如``cinder-scheduler``的進程進行直接交互。它也能夠與這些進程經過一個消息隊列進行交互。``cinder-volume``服務響應送到塊存儲服務的讀寫請求來維持狀態。它也能夠和多種存儲提供者在驅動架構下進行交互。
3）cinder-scheduler守護進程
選擇最優存儲提供節點來建立卷。其與``nova-scheduler``組件相似。
4）cinder-backup守護進程
``cinder-backup``服務提供任何種類備份捲到一個備份存儲提供者。就像``cinder-volume``服務，它與多種存儲提供者在驅動架構下進行交互。
5）消息隊列
在塊存儲的進程之間路由信息。sql

9.1.在控制節點安裝cinder存儲服務

# Install and configure controller node
https://docs.openstack.org/cinder/rocky/install/cinder-controller-install-rdo.html數據庫

1）建立cinder數據庫

# 建立相關數據庫，受權訪問用戶json

mysql -u root -p123456
----------------------------------------
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';
flush privileges;
show databases;
select user,host from mysql.user;
exit
----------------------------------------

2）在keystone上面註冊cinder服務（建立服務證書）

# 在keystone上建立cinder用戶vim

cd /server/tools
source keystone-admin-pass.sh
openstack user create --domain default --password=cinder cinder
openstack user list

# 在keystone上將cinder用戶配置爲admin角色並添加進service項目，如下命令無輸出

openstack role add --project service --user cinder admin

# 建立cinder服務的實體

openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
openstack service list

# 建立cinder服務的API端點（endpoint）

openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%\(project_id\)s

openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v3/%\(project_id\)s
openstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v3/%\(project_id\)s
openstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v3/%\(project_id\)s
openstack endpoint list

3）安裝cinder相關軟件包

yum install openstack-cinder -y

4）快速修改cinder配置

openstack-config --set  /etc/cinder/cinder.conf database connection  mysql+pymysql://cinder:cinder@controller/cinder
openstack-config --set  /etc/cinder/cinder.conf DEFAULT transport_url  rabbit://openstack:openstack@controller

6）修改nova配置文件

# 配置nova調用cinder服務

openstack-config --set  /etc/nova/nova.conf cinder os_region_name  RegionOne

# 檢查生效的nova配置

grep '^[a-z]' /etc/nova/nova.conf |grep os_region_name

7）重啓nova-api服務

systemctl restart openstack-nova-api.service
systemctl status openstack-nova-api.service

8）啓動cinder存儲服務

# 須要啓動2個服務

systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl status openstack-cinder-api.service openstack-cinder-scheduler.service

systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service

# 至此，控制端的cinder服務安裝完畢，在dashboard上面能夠看到項目目錄中多了一個卷服務

# 接下來安裝塊存儲節點服務器storage node

9.2.在存儲節點服務器安裝cinder存儲服務

# 存儲節點建議單獨部署服務器（最好是物理機），測試時也能夠部署在控制節點或者計算節點
# 在本文，存儲節點使用LVM邏輯卷提供服務，須要提供一塊空的磁盤用以建立LVM邏輯卷
# 我這裏在VMware虛擬機增長一塊100GB的磁盤

1）安裝LVM相關軟件包

yum install lvm2 device-mapper-persistent-data -y

2）啓動LVM的metadata服務並配置開機自啓動

systemctl start lvm2-lvmetad.service
systemctl status lvm2-lvmetad.service

systemctl enable lvm2-lvmetad.service
systemctl list-unit-files |grep lvm2-lvmetad |grep enabled

3）建立LVM邏輯卷

# 檢查磁盤狀態

fdisk -l

# 建立LVM 物理卷 /dev/sdb

pvcreate /dev/sdb

# 建立 LVM 卷組 cinder-volumes，塊存儲服務會在這個卷組中建立邏輯卷

vgcreate cinder-volumes /dev/sdb

# 實例演示：

[root@openstack02 ~]# fdisk -l

磁盤 /dev/sda：536.9 GB, 536870912000 字節，1048576000 個扇區
Units = 扇區 of 1 * 512 = 512 bytes
扇區大小(邏輯/物理)：512 字節 / 512 字節
I/O 大小(最小/最佳)：512 字節 / 512 字節
磁盤標籤類型：dos
磁盤標識符：0x0003970d

   設備 Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048     1026047      512000   83  Linux
/dev/sda2         1026048  1044381695   521677824   83  Linux
/dev/sda3      1044381696  1048575999     2097152   82  Linux swap / Solaris

磁盤 /dev/sdb：107.4 GB, 107374182400 字節，209715200 個扇區
Units = 扇區 of 1 * 512 = 512 bytes
扇區大小(邏輯/物理)：512 字節 / 512 字節
I/O 大小(最小/最佳)：512 字節 / 512 字節

[root@openstack02 ~]# pvcreate /dev/sdb
  Physical volume "/dev/sdb" successfully created.
[root@openstack02 ~]# vgcreate cinder-volumes /dev/sdb
  Volume group "cinder-volumes" successfully created

# ok

4）配置過濾器，防止系統出錯

# 默認只會有openstack實例訪問塊存儲卷組，不過，底層的操做系統也會管理這些設備並嘗試將邏輯卷與系統關聯。
# 默認狀況下LVM卷掃描工具會掃描整個/dev目錄，查找全部包含lvm卷的塊存儲設備。若是其餘項目在某個磁盤設備sda，sdc等上使用了lvm卷，那麼掃描工具檢測到這些卷時會嘗試緩存這些lvm卷，可能致使底層操做系統或者其餘服務沒法正常調用他們的lvm卷組，從而產生各類問題，須要手動配置LVM，讓LVM卷掃描工具只掃描包含"cinder-volume"卷組的設備/dev/sdb，我這邊磁盤分區都是格式化的手工分區，目前不存在這個問題，如下是配置演示

vim /etc/lvm/lvm.conf
-----------------------------
devices {
filter = [ "a/sdb/", "r/.*/"]
}
-----------------------------

# 配置規則：

# 每一個過濾器組中的元素都以a開頭accept接受，或以 r 開頭reject拒絕，後面鏈接設備名稱的正則表達式規則。
# 過濾器組必須以"r/.*/"結束，過濾全部保留設備。
# 可使用命令:vgs -vvvv來測試過濾器。

# 注意：

# 若是存儲節點的操做系統磁盤/dev/sda使用的是LVM卷組，也須要將該設備添加到過濾器中，例如：
filter = [ "a/sda/", "a/sdb/", "r/.*/"]
# 若是計算節點的操做系統磁盤/dev/sda使用的是LVM卷組，也須要修改這些節點的/etc/lvm/lvm.conf，在過濾器中增長該類型的磁盤設備，例如：
filter = [ "a/sda/", "r/.*/"]

5）在存儲節點安裝配置cinder組件

yum install openstack-cinder targetcli python-keystone -y

6）在存儲節點快速修改cinder配置

openstack-config --set  /etc/cinder/cinder.conf database connection  mysql+pymysql://cinder:cinder@controller/cinder

systemctl enable openstack-cinder-volume.service target.service
systemctl list-unit-files |grep openstack-cinder |grep enabled

# 至此，在存儲節點安裝cinder服務就完成了

9.3.在控制節點進行驗證

1）獲取管理員變量

cd /server/tools/
source keystone-admin-pass.sh

2）查看存儲卷列表

openstack volume service list

# 實例演示：

[root@openstack01 tools]# openstack volume service list
+------------------+-------------------------------+------+---------+-------+----------------------------+
| Binary           | Host                          | Zone | Status  | State | Updated At                 |

+------------------+-------------------------------+------+---------+-------+----------------------------+

# 返回以上信息，表示cinder相關節點安裝完成

9.4.cinder雲磁盤使用建議

1）雲磁盤能夠進行磁盤遷移，擴容，縮容等操做，但不建議在生產環境進行嘗試，測試環境能夠嘗試，但也要注意備份數據

2）涉及重要數據的話儘可能仍是不使用雲磁盤，而採用本地磁盤存儲數據，若是出現問題至少各個磁盤數據是分開的，磁盤文件還在

3）總的來講，使用openstack部署企業私有云，生產環境用本地磁盤就好，測試環境能夠以嘗試使用雲磁盤
