openstack-T 之Cinder

1、创建数据库

使用数据库访问客户端，以 root 用户身份连接到数据库服务器。
mysql -u root -p依次执行以下命令创建数据库并设置访问权限，完成之后退出数据库访问客户端。这
里 cinder 用户的密码设为 cinder123
MariaDB [(none)]> CREATE DATABASE cinder;MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder123';MariaDB [(none)]> exit;

2、创建cinder服务凭据

创建用户：cinder

openstack user create --domain default --password-prompt cinder

将角色添加到用户：admin

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

创建和服务实体：cinderv2cinderv3

openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3

创建块存储服务 API 端点：

#V2的
openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%\(project_id\)sopenstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%\(project_id\)sopenstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%\(project_id\)s#下面是V3的
openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v3/%\(project_id\)sopenstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v3/%\(project_id\)sopenstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v3/%\(project_id\)s

在控制节点上安装Cinder组件

1．安装软件包

yum -y install openstack-cinder

2、编辑文件并完成以下操作：/etc/cinder/cinder.conf

[database]
connection = mysql+pymysql://cinder:cinder123@controller/cinder[DEFAULT]
transport_url = rabbit://openstack:openstack123@controller[DEFAULT]
auth_strategy = keystone[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = cinder123[DEFAULT]
my_ip = 10.0.0.11[oslo_concurrency]
lock_path = /var/lib/cinder/tmp填充块存储数据库：
su -s /bin/sh -c "cinder-manage db sync" cinder

3、在控制节点配置计算服务使用块存储服务

编辑/etc/nova/nova.conf 配置文件，在[cinder]节中添加以下设置：

[cinder]
os_region_name = RegionOne

完成安装

1、重新启动计算 API 服务：

systemctl restart openstack-nova-api.service

2、启动块存储服务，并将其配置为在系统引导时启动：

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

在存储节点上完成Cinder的安装

将计算节点作为存储节点

1、在存储节点主机上增加一块硬盘sdb

2、安装支持工具包

CentOS 7 操作系统默认已安装 LVM 包。如果没有安装，执行以下命令安装 LVM 包，

启动 LVM 元数据服务并将其配置为开机自动启动。

yum -y install lvm2 device-mapper-persistent-data
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service

3、创建 LVM 物理卷/dev/sdb

[root@compute1 ~]# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created

4、基于该物理卷创建 LVM 卷组 cinder-volumes

[root@compute1 ~]# vgcreate cinder-volumes /dev/sdb
Volume group "cinder-volumes" successfully created

5、编辑/etc/lvm/lvm.conf 文件

在“devices”节中添加一个过滤器来接受/dev/sdb 设备并拒绝所有其他设备。

devices {

...

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

6、在存储节点（计算节点）安装Cinder组件并配置

1、首先安装软件包。

yum -y install openstack-cinder targetcli python-keystone

2、编辑/etc/cinder/cinder.conf 文件并完成相应设置

[database]
connection = mysql+pymysql://cinder:cinder123@controller/cinder[DEFAULT]transport_url = rabbit://openstack:openstack123@controller[DEFAULT]
auth_strategy = keystone[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = cinder123[DEFAULT]
# ...
my_ip = 10.0.0.31  #计算节点的IP，以实际为准[lvm]        #没有就加在后面
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
target_protocol = iscsi
target_helper = lioadm[DEFAULT]
enabled_backends = lvm[DEFAULT]
glance_api_servers = http://controller:9292[oslo_concurrency]
lock_path = /var/lib/cinder/tmp

3、在存储节点（计算节点）

启动块存储卷服务及其依赖组件，并配置它们开机自动启动。

systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service

验证

1、在控制节点上加载 admin 凭据，以获取管理员权限。

. admin-openrc

2、执行以下命令列出 Cinder 块存储服务组件。

[root@controller ~]# openstack volume service list

[root@controller ~]#  openstack volume service list
+------------------+--------------+------+---------+-------+----------------------------+
| Binary           | Host         | Zone | Status  | State | Updated At                 |
+------------------+--------------+------+---------+-------+----------------------------+
| cinder-scheduler | controller   | nova | enabled | up    | 2022-06-05T11:38:01.000000 |
| cinder-volume    | compute1@lvm | nova | enabled | up    | 2022-06-05T11:38:02.000000 |
+------------------+--------------+------+---------+-------+----------------------------+

3、创建卷进行要测试

在控制节点上创建一个卷，并指定可用域、卷大小。

[root@controller ~]# openstack volume create --size 5 --availability-zone nova testVol

[root@controller ~]#  openstack volume create --size 5 --availability-zone nova testVol
+---------------------+--------------------------------------+

| multiattach         | False                                |
| name                | testVol                              |
| properties          |                                      |
| replication_status  | None                                 |
| size                | 5                                    |
| snapshot_id         | None                                 |
| source_volid        | None                                 |
| status              | creating                             |
| type                | __DEFAULT__                          |
| updated_at          | None                                 |
| user_id             | 5adedd33881042a3b87857d30066cf2a     |
+---------------------+--------------------------------------+

创建完毕，测试

[root@controller ~]#  openstack volume list
+--------------------------------------+---------+-----------+------+-------------+
| ID                                   | Name    | Status    | Size | Attached to |

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

成功！！
