OpenStack-Pike 搭建之Cinder（七）

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。

块存储服务通常包含下列组件：

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 daemon

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。
消息队列

在块存储的进程之间路由信息。

安装并配置控制节点

先决条件

1、创建数据库

root 用户连接到数据库服务器

mysql -u root -p000000

创建 cinder 数据库

CREATE DATABASE cinder;

允许 cinder 数据库的cinder用户访问权限：

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY '000000';

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY '000000';

2、获取 admin 凭证

. admin-openrc

3、创建服务证书

创建一个 cinder 用户

openstack user create --domain default --password 000000 cinder

添加 admin 角色到 cinder 用户上

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

创建服务实体

openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2

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

创建服务API

openstack endpoint create --region RegionOne \
  volumev2 public http://controller:8776/v2/%\(project_id\)s

openstack endpoint create --region RegionOne \
  volumev2 internal http://controller:8776/v2/%\(project_id\)s

openstack endpoint create --region RegionOne \
  volumev2 admin http://controller:8776/v2/%\(project_id\)s

openstack endpoint create --region RegionOne \
  volumev3 public http://controller:8776/v3/%\(project_id\)s

openstack endpoint create --region RegionOne \
  volumev3 internal http://controller:8776/v3/%\(project_id\)s

openstack endpoint create --region RegionOne \
  volumev3 admin http://controller:8776/v3/%\(project_id\)s

安装并配置组件

1、安装软件包

yum install -y openstack-cinder

2、配置 cinder.conf

# sed -i.bak '/^#/d;/^$/d' /etc/cinder/cinder.conf

# vim /etc/cinder/cinder.conf

[database]
# 配置数据库访问
connection = mysql+pymysql://cinder:000000@controller/cinder

[DEFAULT]
# 配置RabbitMQ 消息队列访问
transport_url = rabbit://openstack:000000@controller
# 配置身份服务访问
auth_strategy = keystone
# 控制器节点的管理接口 IP 地址
my_ip = 178.120.2.100

[keystone_authtoken]
# 配置身份服务访问

配置计算节点使用块设备存储

配置 nova.conf

# vim /etc/nova/nova.conf 

[cinder]
os_region_name = RegionOne

完成安装

1、重启计算API服务

systemctl restart openstack-nova-api.service

2、启动设备块存储服务并设置开机自启

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

  Physical volume "/dev/vdb" successfully created.
[root@storage_node ~]# vgcreate cinder-volumes /dev/vdb
  Volume group "cinder-volumes" successfully create

{/collapse-item}

安装并配置组件

1、安装软件包
