块存储服务

安装并配置控制节点

创建数据库

[root@controller ~]# mysql -u root -pshg12345
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';

获取admin凭证

创建服务证书

创建一个 cinder 用户 添加 admin 角色到 cinder 用户上

[root@controller ~]# openstack user create --domain default --password cinder cinder
[root@controller ~]# openstack role add --project service --user cinder admin

创建 cinder 和 cinderv2 服务实体

[root@controller ~]# openstack service create --name cinder \
>   --description "OpenStack Block Storage" volume
[root@controller ~]# openstack service create --name cinderv2 \
>   --description "OpenStack Block Storage" volumev2

创建块设备存储服务的 API 入口点

[root@controller ~]# openstack endpoint create --region RegionOne \
>   volume public http://controller:8776/v1/%\(tenant_id\)s
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volume internal http://controller:8776/v1/%\(tenant_id\)s
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volume admin http://controller:8776/v1/%\(tenant_id\)s

[root@controller ~]# openstack endpoint create --region RegionOne \
>   volumev2 public http://controller:8776/v2/%\(tenant_id\)s
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volumev2 internal http://controller:8776/v2/%\(tenant_id\)s
[root@controller ~]# openstack endpoint create --region RegionOne \
>   volumev2 admin http://controller:8776/v2/%\(tenant_id\)s

[DEFAULT]
auth_strategy = keystone
[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 = cinder

配置``my_ip`` 来使用控制节点的管理接口的IP 地址

[DEFAULT]
my_ip = 192.168.81.11

配置锁路径

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

初始化块设备服务的数据库

[root@controller ~]# su -s /bin/sh -c "cinder-manage db sync" cinder

配置计算节点以使用块设备存储

[root@controller ~]# vim /etc/nova/nova.conf
[cinder]
os_region_name = RegionOne

[root@controller ~]# systemctl restart openstack-nova-api.service
[root@controller ~]# systemctl enable --now openstack-cinder-api.service openstack-cinder-scheduler.service

安装并配置一个存储节点

新建虚机block1，拷贝仓库，无需更改网卡，软件包更新，新增硬盘sdb

创建LVM 物理卷 /dev/sdb 创建 LVM 卷组 cinder-volumes

[root@block1 ~]# yum install lvm2
[root@block1 ~]# systemctl enable --now lvm2-lvmetad.service
[root@block1 ~]# pvcreate /dev/sdb
[root@block1 ~]# vgcreate cinder-volumes /dev/sdb

安全并配置组件

[root@block1 ~]# yum install openstack-cinder targetcli python-keystone
[root@block1 ~]# vim /etc/cinder/cinder.conf
