1、OpenStack-cinder 组件部署

1.1、创建数据库实例和角色

[root@ct ~]# mysql -uroot -p123456
MariaDB [(none)]> CREATE DATABASE cinder;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CINDER_DBPASS';
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> show databases;
MariaDB [(none)]> exit

1.2、创建用户、修改配置文件

1.2.1、创建cinder用户,密码设置为CINDER_PASS

[root@ct ~]# openstack user create --domain default --password CINDER_PASS cinder

在这里插入图片描述

1.2.2、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

1.2.3、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
[root@ct ~]# openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3

在这里插入图片描述

1.2.4、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
[root@ct ~]# openstack endpoint create --region RegionOne volumev2 internal http://ct:8776/v2/%\(project_id\)s
[root@ct ~]# openstack endpoint create --region RegionOne volumev2 admin http://ct:8776/v2/%\(project_id\)s
[root@ct ~]# openstack endpoint create --region RegionOne volumev3 public http://ct:8776/v3/%\(project_id\)s
[root@ct ~]# openstack endpoint create --region RegionOne volumev3 internal http://ct:8776/v3/%\(project_id\)s
[root@ct ~]# openstack endpoint create --region RegionOne volumev3 admin http://ct:8776/v3/%\(project_id\)s

在这里插入图片描述

1.3、yum 安装cinder 服务

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

1.3.1、修改cinder 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 DEFAULT my_ip 192.168.74.11
[root@ct ~]# openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp
[root@ct ~]# cd /etc/cinder/
[root@ct cinder]# cat cinder.conf
[DEFAULT]
transport_url = rabbit://openstack:RABBIT_PASS@ct			#配置rabbitmq连接
auth_strategy = keystone						#认证方式

1.3.2、同步cinder数据库(填充块存储数据库)

1.3.3、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

1.3.4、配置Cinder服务

[root@ct ~]# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
[root@ct ~]# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

1.3.5、配置控制节点验证

[root@ct ~]# cinder service-list

1.4、在计算节点c2配置Cinder（存储节点）

[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

1.4.1、创建lvm物理卷和卷组（新建一块硬盘，并重启）

[root@c2 ~]# pvcreate /dev/sdc
  Physical volume "/dev/sdc" successfully created.
[root@c2 ~]# vgcreate cinder-volumes /dev/sdc
  Volume group "cinder-volumes" successfully created

1.4.2、修改lvm配置文件(指定使用sdc磁盘）

[root@c2 ~]# vim /etc/lvm/lvm.conf
141行，取消，
# 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

在这里插入图片描述

1.4.3、重启lvm服务

[root@c2 ~]# systemctl restart lvm2-lvmetad.service

1.4.4、配置cinder模块

[lvm]							 #为LVM后端配置LVM驱动程序
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver	#指定LVM驱动程序；即通过指定的驱动创建LVM
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

1.4.5、开启cinder卷服务

[root@c2 ~]# systemctl enable openstack-cinder-volume.service target.service
[root@c2 ~]# systemctl start openstack-cinder-volume.service target.service

1.4.6、查看卷列表

[root@ct ~]# openstack volume service list

在这里插入图片描述

2、小结

1、Cinder配置思路：
创建管理、对接的用户、密码、服务和endpoint
2、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
3、配置计算节点中虚拟机所用的卷
