9.0.Cinder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：
1）cinder-api
接受API请求，并将其路由到``cinder-volume``执行。
2）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。
3）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。
4）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。
5）消息队列
在块存储的进程之间路由信息。
9.1.在控制节点安装cinder存储服务
# Install and configure controller node
https://docs.openstack.org/cinder/rocky/install/cinder-controller-install-rdo.html
1）创建cinder数据库
# 创建相关数据库，授权访问用户
mysql -u root -p123456
----------------------------------------
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';
flush privileges;
show databases;
select user,host from mysql.user;
exit
----------------------------------------
2）在keystone上面注册cinder服务（创建服务证书）
# 在keystone上创建cinder用户
cd /server/tools
source keystone-admin-pass.sh
openstack user create --domain default --password=cinder cinder
openstack user list
# 在keystone上将cinder用户配置为admin角色并添加进service项目，以下命令无输出
openstack role add --project service --user cinder admin
# 创建cinder服务的实体
openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
openstack service list
# 创建cinder服务的API端点（endpoint）
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
openstack endpoint list

# 至此，控制端的cinder服务安装完毕，在dashboard上面可以看到项目目录中多了一个卷服务
# 接下来安装块存储节点服务器storage node
9.2.在存储节点服务器安装cinder存储服务
# 存储节点建议单独部署服务器（最好是物理机），测试时也可以部署在控制节点或者计算节点
# 在本文，存储节点使用LVM逻辑卷提供服务，需要提供一块空的磁盘用以创建LVM逻辑卷
# 我这里在VMware虚拟机增加一块100GB的磁盘
1）安装LVM相关软件包
yum install lvm2 device-mapper-persistent-data -y
2）启动LVM的metadata服务并配置开机自启动
systemctl start lvm2-lvmetad.service
systemctl status lvm2-lvmetad.service systemctl enable lvm2-lvmetad.service
systemctl list-unit-files |grep lvm2-lvmetad |grep enabled
3）创建LVM逻辑卷
# 检查磁盘状态
fdisk -l
# 创建LVM 物理卷 /dev/sdb
pvcreate /dev/sdb
# 创建 LVM 卷组 cinder-volumes，块存储服务会在这个卷组中创建逻辑卷
vgcreate cinder-volumes /dev/sdb
# 实例演示：
[root@openstack02 ~]# fdisk -l 磁盘 /dev/sda：536.9 GB, 536870912000 字节，1048576000 个扇区
Units = 扇区 of 1 * 512 = 512 bytes
扇区大小(逻辑/物理)：512 字节 / 512 字节

Units = 扇区 of 1 * 512 = 512 bytes
扇区大小(逻辑/物理)：512 字节 / 512 字节
I/O 大小(最小/最佳)：512 字节 / 512 字节 [root@openstack02 ~]# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created.
[root@openstack02 ~]# vgcreate cinder-volumes /dev/sdb
Volume group "cinder-volumes" successfully created
# ok
4）配置过滤器，防止系统出错
# 默认只会有openstack实例访问块存储卷组，不过，底层的操作系统也会管理这些设备并尝试将逻辑卷与系统关联。
# 默认情况下LVM卷扫描工具会扫描整个/dev目录，查找所有包含lvm卷的块存储设备。如果其他项目在某个磁盘设备sda，sdc等上使用了lvm卷，那么扫描工具检测到这些卷时会尝试缓存这些lvm卷，可能导致底层操作系统或者其他服务无法正常调用他们的lvm卷组，从而产生各种问题，需要手动配置LVM，让LVM卷扫描工具只扫描包含"cinder-volume"卷组的设备/dev/sdb，我这边磁盘分区都是格式化的手工分区，目前不存在这个问题，以下是配置演示
vim /etc/lvm/lvm.conf
-----------------------------
devices {
filter = [ "a/sdb/", "r/.*/"]
}
-----------------------------
# 配置规则：
# 每个过滤器组中的元素都以a开头accept接受，或以 r 开头reject拒绝，后面连接设备名称的正则表达式规则。
# 过滤器组必须以"r/.*/"结束，过滤所有保留设备。
# 可以使用命令:vgs -vvvv来测试过滤器。
# 注意：
# 如果存储节点的操作系统磁盘/dev/sda使用的是LVM卷组，也需要将该设备添加到过滤器中，例如：
filter = [ "a/sda/", "a/sdb/", "r/.*/"]
# 如果计算节点的操作系统磁盘/dev/sda使用的是LVM卷组，也需要修改这些节点的/etc/lvm/lvm.conf，在过滤器中增加该类型的磁盘设备，例如：
filter = [ "a/sda/", "r/.*/"]
5）在存储节点安装配置cinder组件
yum install openstack-cinder targetcli python-keystone -y
6）在存储节点快速修改cinder配置
openstack-config --set /etc/cinder/cinder.conf database connection mysql+pymysql://cinder:cinder@controller/cinder

openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp
# 如果存储节点是双网卡，选项my_ip需要配置存储节点的管理IP，否则配置本机IP

7）在存储节点启动cinder服务并配置开机自启动
# 需要启动2个服务
systemctl start openstack-cinder-volume.service target.service
systemctl status openstack-cinder-volume.service target.service systemctl enable openstack-cinder-volume.service target.service
systemctl list-unit-files |grep openstack-cinder |grep enabled
systemctl list-unit-files |grep target.service |grep enabled
# 实例演示：

[root@openstack02 ~]# systemctl status openstack-cinder-volume.service target.service

[root@openstack02 ~]# systemctl list-unit-files |grep target.service |grep enabled

# 至此，在存储节点安装cinder服务就完成了
9.3.在控制节点进行验证
1）获取管理员变量
cd /server/tools/
source keystone-admin-pass.sh
2）查看存储卷列表
openstack volume service list
# 实例演示：
[root@openstack01 tools]# openstack volume service list
+------------------+-------------------------------+------+---------+-------+----------------------------+
| Binary | Host | Zone | Status | State | Updated At |
+------------------+-------------------------------+------+---------+-------+----------------------------+
| cinder-scheduler | openstack01.zuiyoujie.com | nova | enabled | up | 2018-10-31T10:55:19.000000 |
| cinder-volume | openstack02.zuiyoujie.com@lvm | nova | enabled | up | 2018-10-31T10:55:21.000000 |
+------------------+-------------------------------+------+---------+-------+----------------------------+
# 返回以上信息，表示cinder相关节点安装完成
9.4.cinder云磁盘使用建议
1）云磁盘可以进行磁盘迁移，扩容，缩容等操作，但不建议在生产环境进行尝试，测试环境可以尝试，但也要注意备份数据
2）涉及重要数据的话尽量还是不使用云磁盘，而采用本地磁盘存储数据，如果出现问题至少各个磁盘数据是分开的，磁盘文件还在
3）总的来说，使用openstack部署企业私有云，生产环境用本地磁盘就好，测试环境可以以尝试使用云磁盘
======== 完毕，呵呵呵呵 ========
