OpenStack（7）-cinder服務部署

OpenStack Block Storage服務（Cinder）將持久存儲添加到虛擬機。塊存儲提供用於管理卷的基礎結構，並與OpenStack Compute交互以為實例提供卷。該服務還可以管理卷快照和卷類型。

塊存儲服務包含以下組件：

cinderAPI

接受API請求，並將它們路由到 cinder-volume for操作。

cinder卷

直接與Block Storage服務以及諸如之后的進程交互 cinder-scheduler 。它還通過消息隊列與這些進程交互。該 cinder-volume 服務響應發送到塊存儲服務的讀寫請求以維持狀態。它可以通過驅動程序體系結構與各種存儲提供程序進行交互。

cinder-scheduler守護進程

選擇要在其上創建卷的最佳存儲提供程序節點。一個類似的組成部分 nova-scheduler 。

cinder-backup守護進程

該 cinder-backup 服務為備份存儲提供程序提供任何類型的備份卷。與 cinder-volume 服務一樣，它可以通過驅動程序體系結構與各種存儲提供程序進行交互。

消息隊列

          消息隊列在塊存儲進程之間路由信息。

我們需要在存儲節點添加一塊硬盤sdb

我們先配置控制節點

1.創建cinder數據庫；

mysql> CREATE DATABASE cinder;
Query OK, 1 row affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
    ->   IDENTIFIED BY '123';
Query OK, 0 rows affected, 1 warning (0.15 sec)

mysql> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
    ->   IDENTIFIED BY '123';
Query OK, 0 rows affected, 1 warning (0.00 sec)

2.創建cinder用戶；

[root@sxb1 ~]# openstack user create --domain default --password-prompt cinder
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | c14cbc9906274a968452fbe7a3f67474 |
| name                | cinder                           |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

3.將admin角色添加到cinder用戶；

[root@sxb1 ~]# openstack role add --project service --user cinder admin

4.創建cinder服務cinderv2、cinderv3（因為有兩個版本）；

[root@sxb1 ~]# openstack service create --name cinderv2 \
>   --description "OpenStack Block Storage" volumev2
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Block Storage          |
| enabled     | True                             |
| id          | 049c3b344b134b5695a7223658a0c625 |
| name        | cinderv2                         |
| type        | volumev2                         |
+-------------+----------------------------------+

[root@sxb1 ~]# openstack service create --name cinderv3 \
>   --description "OpenStack Block Storage" volumev3
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Block Storage          |
| enabled     | True                             |
| id          | 896ebdd517f44b45bc9c5beb9e7e3192 |
| name        | cinderv3                         |
| type        | volumev3                         |
+-------------+----------------------------------+

5.創建Block Storage服務API端點；

卷2

[root@sxb1 ~]# openstack endpoint create --region RegionOne   volumev2 public http://192.168.88.101:8776/v2/%\(project_id\)s^C
[root@sxb1 ~]# openstack endpoint create --region RegionOne   volumev2 internal http://192.168.88.101:8776/v2/%\(project_id\)s^C
[root@sxb1 ~]# openstack endpoint create --region RegionOne   volumev2 admin http://192.168.88.101:8776/v2/%\(project_id\)s

卷3

[root@sxb1 ~]# openstack endpoint create --region RegionOne   volumev3 public http://192.168.88.101:8776/v3/%\(project_id\)s^C
[root@sxb1 ~]# openstack endpoint create --region RegionOne   volumev3 internal http://192.168.88.101:8776/v3/%\(project_id\)s^C
[root@sxb1 ~]# openstack endpoint create --region RegionOne   volumev3 admin http://192.168.88.101:8776/v3/%\(project_id\)s

6.安裝cinder相關組件；

[root@sxb1 ~]# yum install openstack-cinder -y

7.配置cinder文件；

[root@sxb1 ~]# vim /etc/cinder/cinder.conf 

[DEFAULT]
transport_url = rabbit://openstack:123@192.168.88.101
auth_strategy = keystone

[database]
connection = mysql+pymysql://cinder:123@192.168.88.101/cinder

[keystone_authtoken]
www_authenticate_uri = http://192.168.88.101:5000
auth_url = http://192.168.88.101:5000
memcached_servers = 192.168.88.101:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = 123

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp

8.初始化數據庫（返回信息不用管）；

[root@sxb1 ~]# su -s /bin/sh -c "cinder-manage db sync" cinder
Deprecated: Option "logdir" from group "DEFAULT" is deprecated. Use option "log-dir" from group "DEFAULT".

9.配置nova文件；

[root@sxb1 ~]# vim /etc/nova/nova.conf

[cinder]
os_region_name = RegionOne

10.重啟nova服務；

[root@sxb1 ~]# systemctl restart openstack-nova-api.service

11.啟動控制節點cinder服務（status查看服務狀態）；

[root@sxb1 ~]# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-api.service to /usr/lib/systemd/system/openstack-cinder-api.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-scheduler.service to /usr/lib/systemd/system/openstack-cinder-scheduler.service.
[root@sxb1 ~]# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

我們來配置存儲節點

1.安裝cinder相關組件；

[root@sxb3 ~]# yum install lvm2 device-mapper-persistent-data -y

2.啟動cinder服務；

[root@sxb3 ~]# systemctl enable lvm2-lvmetad.service
[root@sxb3 ~]# systemctl start lvm2-lvmetad.service
[root@sxb3 ~]# systemctl status lvm2-lvmetad.service
● lvm2-lvmetad.service - LVM2 metadata daemon
   Loaded: loaded (/usr/lib/systemd/system/lvm2-lvmetad.service; static; vendor preset: enabled)

           └─519 /usr/sbin/lvmetad -f

Sep 09 07:28:32 sxb3.103.com systemd[1]: Started LVM2 metadata daemon.

3.創建一個LVM；

[root@sxb3 ~]# pvcreate /dev/sdb
  Physical volume "/dev/sdb" successfully created.
[root@sxb3 ~]# vgcreate cinder-volumes /dev/sdb
  Volume group "cinder-volumes" successfully created

4.配置lvm文件；

[root@sxb3 ~]# vim /etc/lvm/lvm.conf 

devices {
        filter = [ "a/sdb/", "r/.*/"]

5.安裝組件；

[root@sxb3 ~]# yum install openstack-cinder targetcli python-keystone -y

6.配置cinder文件；

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
target_protocol = iscsi
target_helper = lioadm

[DEFAULT]
transport_url = rabbit://openstack:123@192.168.88.101
auth_strategy = keystone
my_ip = 192.168.88.103
enabled_backends = lvm
glance_api_servers = http://192.168.88.101:9292

[database]
connection = mysql+pymysql://cinder:123@192.168.88.101/cinder

[keystone_authtoken]
www_authenticate_uri = http://192.168.88.101:5000
auth_url = http://192.168.88.101:5000
memcached_servers = 192.168.88.101:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = 123

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp

7.啟動cinder服務（status查看服務狀態）；

[root@sxb3 ~]# systemctl enable openstack-cinder-volume.service target.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-volume.service to /usr/lib/systemd/system/openstack-cinder-volume.service.
