Centos7.4安装openstack（queens）详细安装部署（七）块存储服务

一、基本概念

　　1.1、概述：OpenStack块存储服务(cinder)为虚拟机添加持久的存储，块存储提供一个基础设施为了管理卷，以及和OpenStack计算服务交互，为实例提供卷。此服务也会激活管理卷的快照和卷类型的功能。

　　1.2、基本组件

　　　　cinder-api 接受API请求，并将其路由到``cinder-volume``执行。

　　　　cinder-volume：与块存储服务和例如``cinder-scheduler``的进程进行直接交互。它也可以与这些进程通过一个消息队列进行交互。``cinder-volume``服务响应送到块存储服务的读写请求来维持状态。它也可以和多种存储提供者在驱动架构下进行交互。

　　　　cinder-scheduler守护进程：选择最优存储提供节点来创建卷。其与``nova-scheduler``组件类似。

　　　　cinder-backup守护进程：cinder-backup服务提供任何种类备份卷到一个备份存储提供者。就像``cinder-volume``服务，它与多种存储提供者在驱动架构下进行交互。

二、控制节点安装服务

　　1、创库授权

mysql -u root -pADMIN_PASS

CREATE DATABASE cinder;

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'ADMIN_PASS';

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'ADMIN_PASS';

　　2、在keysonte上创建系统用户

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

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

　　3、在keysonte上创建服务和注册api

openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2      创建cinderv2服务实体

创建块设备存储服务的 API 入口点
  
openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%(tenant_id)s
  
openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%(tenant_id)s
  
openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%(tenant_id)s

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

openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v2/%(tenant_id)s

openstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v2/%(tenant_id)s

openstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v2/%(tenant_id)s

　　4、安装服务

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
yum makecache
yum install centos-release-openstack-queens.noarch -y
yum install openstack-cinder -y
yum install openstack-utils -y

 　　5、修改配置文件

cp /etc/cinder/cinder.conf{,.bak}
grep -Ev '^$|#' /etc/cinder/cinder.conf.bak >/etc/cinder/cinder.conf

openstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend rabbit
openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 10.0.0.11
openstack-config --set /etc/cinder/cinder.conf database connection  mysql+pymysql://cinder:ADMIN_PASS@controller/cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_uri http://controller:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_url http://controller:35357
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_type password
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_domain_name default
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken user_domain_name default
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_name service
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken username cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken password ADMIN_PASS
openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp
openstack-config --set /etc/cinder/cinder.conf oslo_messaging_rabbit rabbit_host controller
openstack-config --set /etc/cinder/cinder.conf oslo_messaging_rabbit rabbit_userid openstack
openstack-config --set /etc/cinder/cinder.conf oslo_messaging_rabbit rabbit_password ADMIN_PASS

　　6、配置计算节点以使用块设备存储

[cinder]
os_region_name = RegionOne

　　7、同步数据库

su -s /bin/sh -c "cinder-manage db sync" cinder

　　8、重启服务

　　　　控制节点重启计算API 服务

systemctl restart openstack-nova-api.service

　　　　计算节点重启openstack-nova-compute服务

systemctl restart openstack-nova-compute.service

　　 9、启动服务

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

　　 10、验证服务，web页面会多出一个卷管理

cinder service-list

 三、存储节点安装服务

　　1、LVM拓扑图

 　　2、添加两块硬盘，不关机识别

echo '- - -' >/sys/class/scsi_host/host0/scan
fdisk -l

　　

 　　3、原理图

 　　4、安装支持的工具包

yum makecache
yum install centos-release-openstack-queens.noarch -y
yum install lvm2 -y

  systemctl enable lvm2-lvmetad
  systemctl start lvm2-lvmetad

 　　5、创建物理卷和卷组 

pvcreate /dev/sdb                                     创建LVM 物理卷 
pvcreate /dev/sdc
vgcreate cinder-ssd /dev/sdb                          创建 LVM 卷组
