OpenStack-cinder 组件部署
继Dashboard部署完成后，继续部署cinder组件
创建数据库实例和角色
[root@ct ~]# mysql -uroot -p
Enter password:

创建用户、修改配置文件
1. 创建cinder用户,密码设置为CINDER_PASS
[root@ct ~]# openstack user create --domain default --password CINDER_PASS cinder
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | 9ed2fe5930fd4bff96163acdaff555ae |
| name | cinder |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
2. 把cinder用户添加到service服务中，并授予admin权限
[root@ct ~]# openstack role add --project service --user cinder admin
3. cinder有v2和v3两个并存版本的API，所以需要创建两个版本的service实例
[root@ct ~]# openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Block Storage |
| enabled | True |
| id | 86fc46058bc14d60b9777e593d293662 |
| name | cinderv2 |
| type | volumev2 |
+-------------+----------------------------------+
[root@ct ~]# openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Block Storage |
| enabled | True |
| id | 83e6439a228045dc8896ffdbfd8975a7 |
| name | cinderv3 |
| type | volumev3 |
+-------------+----------------------------------+
4. 给v2和v3版本的api创建endpoint
[root@ct ~]# openstack endpoint create --region RegionOne volumev2 public http://ct:8776/v2/%\(project_id\)s
+--------------+----------------------------------+
| Field | Value |

+--------------+----------------------------------+5. yum 安装cinder 服务
[root@ct ~]# yum -y install openstack-cinder
6. 修改cinder 配置文件
- 修改配置文件
[root@ct ~]# cp /etc/cinder/cinder.conf{,.bak}
[root@ct ~]# grep -Ev '#|^$' /etc/cinder/cinder.conf.bak>/etc/cinder/cinder.conf
[root@ct ~]# openstack-config --set /etc/cinder/cinder.conf database connection mysql+pymysql://cinder:CINDER_DBPASS@ct/cinder
[root@ct ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT transport_url rabbit://openstack:RABBIT_PASS@ct
[root@ct ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
[root@ct ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken www_authenticate_uri http://ct:5000

[root@ct ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 192.168.100.10
[root@ct ~]# openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp
- 查看配置文件
[root@ct ~]# cat /etc/cinder/cinder.conf
[DEFAULT]
transport_url = rabbit://openstack:RABBIT_PASS@ct //配置rabbitmq连接
auth_strategy = keystone //认证方式
my_ip = 192.168.100.11 //内网IP[backend]

7. 同步cinder数据库(填充块存储数据库)
[root@ct ~]# 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".
8. 修改 Nova 配置文件，并重启服务
[root@ct ~]# openstack-config --set /etc/nova/nova.conf cinder os_region_name RegionOne
[root@ct ~]# systemctl restart openstack-nova-api.service
9. 配置Cinder服务
[root@ct ~]# 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@ct ~]# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
10. 配置控制节点验证
[root@ct ~]# cinder service-list
+------------------+------+------+---------+-------+----------------------------+---------+-----------------+---------------+
| Binary | Host | Zone | Status | State | Updated_at | Cluster | Disabled Reason | Backend State |
+------------------+------+------+---------+-------+----------------------------+---------+-----------------+---------------+
| cinder-scheduler | ct | nova | enabled | up | 2021-02-19T06:08:04.000000 | - | - | |
+------------------+------+------+---------+-------+----------------------------+---------+-----------------+---------------+
在计算节点c2配置Cinder（存储节点）
1. 安装cinder及依赖文件，并设置开机自启
[root@c2 ~]# yum -y install openstack-cinder targetcli python-keystone
[root@c2 ~]# yum -y install lvm2 device-mapper-persistent-data
[root@c2 ~]# systemctl enable lvm2-lvmetad.service
[root@c2 ~]# systemctl start lvm2-lvmetad.service
2. 创建lvm物理卷和卷组
注：如若没有sdc则创建一个硬盘并重启
[root@c2 ~]# pvcreate /dev/sdcPhysical volume "/dev/sdc" successfully created.
[root@c2 ~]# vgcreate cinder-volumes /dev/sdcVolume group "cinder-volumes" successfully created
3. 修改lvm配置文件(指定使用sdc磁盘）
[root@c2 ~]# vim /etc/lvm/lvm.conf
141 filter = [ "a/sdc/","r/.*/" ] //取消前面#注释符并修改
- a表示允许，r表示拒绝
- 只允许lvm服务访问sdc中的数据，不允许lvm服务访问其他磁盘，这也间接实现了openstack创建的虚拟机只能访问sdb中的数据，不能访问其他磁盘
- 设置只允许实例访问sdc逻辑卷中的数据；如果不配置的话，本机的其他服务也有可能会访问sdc逻辑卷中的数据
4. 重启lvm服务
[root@c2 ~]# systemctl restart lvm2-lvmetad.service
5. 配置cinder模块
- 修改cinder.conf配置
[root@c2 ~]# cp /etc/cinder/cinder.conf{,.bak}
[root@c2 ~]# grep -Ev '#|^$' /etc/cinder/cinder.conf.bak>/etc/cinder/cinder.conf
[root@c2 ~]#
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf database connection mysql+pymysql://cinder:CINDER_DBPASS@ct/cinder
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT transport_url rabbit://openstack:RABBIT_PASS@ct
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 192.168.100.12 //c2内网ip
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT enabled_backends lvm
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_api_servers http://ct:9292
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken www_authenticate_uri http://ct:5000
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_url http://ct:5000
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken memcached_servers ct:11211
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_type password
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_domain_name default
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken user_domain_name default
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_name service
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken username cinder
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken password CINDER_PASS
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf lvm volume_driver cinder.volume.drivers.lvm.LVMVolumeDriver
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf lvm volume_group cinder-volumes
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf lvm target_protocol iscsi
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf lvm target_helper lioadm
[root@c2 ~]# openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp
- 查看修改内容
[root@c2 ~]# cat /etc/cinder/cinder.conf

volume_group = cinder-volumes //指定卷组(vg)
target_protocol = iscsi //pv使用的是iscsi协议，可以提供块存储服务
target_helper = lioadm //iscsi管理工具#volume_backend_name=Openstack-lvm //选择：当后端有多个不同类型的存储时，可以在openstack中调用指定的存储；
给当前存储指定个名称，用于后期区分多个不同的存储
6. 开启cinder卷服务,并设置开机自启
[root@c2 ~]# 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.
Created symlink from /etc/systemd/system/multi-user.target.wants/target.service to /usr/lib/systemd/system/target.service.
[root@c2 ~]# systemctl start openstack-cinder-volume.service target.service
验证，ct上查看卷列表
[root@ct ~]# openstack volume service list
+------------------+--------+------+---------+-------+----------------------------+
| Binary | Host | Zone | Status | State | Updated At |
+------------------+--------+------+---------+-------+----------------------------+
| cinder-scheduler | ct | nova | enabled | up | 2021-02-19T06:36:04.000000 |
| cinder-volume | c2@lvm | nova | enabled | up | 2021-02-19T06:36:04.000000 |
+------------------+--------+------+---------+-------+----------------------------+
至此，cinder组件部署完成,openstack全部部署成功
总结
Cinder配置思路：
- 创建管理、对接的用户、密码、服务和endpoint
修改配置文件：
- 主要内容为 向keystone对接认证授权、组件之间通讯模块、配置所在的域等
- 配置计算节点中虚拟机所用的卷
