CentOS7安装OpenStack（Queens版）——（七）cinder存储服务

cinder存储服务

安装配置（控制节点）

  1. 创建cinder数据库并授权,自定义帐号密码cinder/cinder
mysql -uroot -p

MariaDB [(none)]> CREATE DATABASE cinder;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';
MariaDB [(none)]> FLUSH PRIVILEGES;
  1. 加载临时环境变量
. keystonerc_admin
  1. 创建服务凭据
    • 创建cinder用户，自定义密码为cinder：
[root@controller-01 ~]# openstack user create --domain default --password-prompt cinder
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 586034dc84fa427baec593ed32501d28 |
| name                | cinder                           |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+
  • 给cinder用户添加admin角色,命令不输出结果：
openstack role add --project service --user cinder admin
  • 创建cinderv2和cinderv3服务实体：
[root@controller-01 ~]# openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Block Storage          |
| enabled     | True                             |
| id          | 08c72135ddcb46fda290c6ec94b270ed |
| name        | cinderv2                         |
| type        | volumev2                         |
+-------------+----------------------------------+

[root@controller-01 ~]# openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Block Storage          |
| enabled     | True                             |
| id          | 671d97addc654760be943446f9c158f6 |
| name        | cinderv3                         |
| type        | volumev3                         |
+-------------+----------------------------------+
  1. 创建块存储服务API端点：
[root@controller-01 ~]# openstack endpoint create --region RegionOne volumev2 public http://controller-01:8776/v2/%\(project_id\)s
+--------------+---------------------------------------------+
| Field        | Value                                       |

安装配置组件

  1. 安装包
yum install openstack-cinder
  1. 编辑/etc/cinder/cinder.conf文件，修改如下配置：
[database]
connection = mysql+pymysql://cinder:cinder@controller-01/cinder

[DEFAULT]
transport_url = rabbit://openstack:openstack@controller-01
auth_strategy = keystone
my_ip = 192.168.1.10

[keystone_authtoken]
auth_uri = http://controller-01:5000
auth_url = http://controller-01:5000
memcached_servers = controller-01:11211
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = cinder

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
  • 检查配置修改
egrep -v "^$|^#" /etc/cinder/cinder.conf
  1. 同步块存储数据库
su -s /bin/sh -c "cinder-manage db sync" cinder
  • 检查数据表
mysql -ucinder -pcinder cinder -e "show tables;"

配置计算使用块存储

  1. 编辑/etc/nova/nova.conf文件，添加修改如下配置：
[cinder]
os_region_name = RegionOne

最后安装

  1. 重启计算API服务
systemctl restart openstack-nova-api.service
  1. 启动块存储服务并设置开机自启
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

安装配置（存储节点）

  1. 安装工具包
    • 安装LVM包
yum install lvm2 device-mapper-persistent-data
  • 启动并配置开机自启动LVM元数据
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service
  1. 创建LVM物理卷/dev/sdb(测试可以通过虚拟机再添加一块磁盘)
pvcreate /dev/sdb
  Physical volume "/dev/sdb" successfully created.
  1. 创建LVM卷组cinder-volumes
vgcreate cinder-volumes /dev/sdb
  Volume group "cinder-volumes" successfully created
  1. 只有实例可以访问块存储卷。但是，底层操作系统管理与卷关联的设备。默认情况下，LVM 卷扫描工具会扫描 /dev包含卷的块存储设备的目录。如果项目在其卷上使用 LVM，则扫描工具会检测到这些卷并尝试缓存它们，这可能会导致底层操作系统和项目卷出现各种问题。您必须重新配置 LVM 以仅扫描包含cinder-volumes卷组的设备。编辑 /etc/lvm/lvm.conf文件并完成以下操作:
    • 在devices部分，添加一个过滤接受/dev/sdb设备并且拒绝所有其他设备：
devices {
filter = [ "a/sdb/", "r/.*/"]
  • 配置规则
# 每个过滤器组中的元素都以a开头accept接受，或以 r 开头reject拒绝，后面连接设备名称的正则表达式规则。
# 过滤器组必须以"r/.*/"结束，过滤所有保留设备。
# 可以使用命令:vgs -vvvv来测试过滤器。
  • 假如你的存储节点系统盘也使用的LVM，你也必须添加该设备到过滤器。举例，假如设备/dev/sda是系统盘：
filter = [ "a/sda/", "a/sdb/", "r/.*/"]
  • 假如你的计算节点系统盘也使用的LVM，你也必须在/etc/lvm/lvm.conf中添加系统盘的过滤器。举例，假如/dev/sda是系统盘：
filter = [ "a/sda/", "r/.*/"]

安装配置组件

  1. 安装包
yum install openstack-cinder targetcli python-keystone
  1. 编辑/etc/cinder/cinder.conf文件，修改如下配置：
[database]
connection = mysql+pymysql://cinder:cinder@controller-01/cinder

[DEFAULT]
transport_url = rabbit://openstack:openstack@controller-01
auth_strategy = keystone
my_ip = 10.0.0.12    # 这里IP填写网卡二IP
enabled_backends = lvm
glance_api_servers = http://controller-01:9292

[keystone_authtoken]
auth_uri = http://controller-01:5000
auth_url = http://controller-01:5000
memcached_servers = controller-01:11211
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = cinder

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
  • 检查配置修改
egrep -v "^$|^#" /etc/cinder/cinder.conf

最后安装

  1. 启动服务并开机自启
systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service

验证(控制节点)

  1. 加载临时环境变量
. keystonerc_admin
  1. 查看存储卷列表
[root@controller-01 ~]# openstack volume service list
+------------------+----------------+------+---------+-------+----------------------------+
| Binary           | Host           | Zone | Status  | State | Updated At                 |

| cinder-scheduler | controller-01  | nova | enabled | up    | 2023-01-07T11:15:38.000000 |
| cinder-volume    | storage-01@lvm | nova | enabled | up    | 2023-01-07T11:15:32.000000 |
