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 I/O 大小(最小/最佳):512 字节 / 512 字节 磁盘标签类型:dos 磁盘标识符:0x0003970d 设备 Boot Start End Blocks Id System /dev/sda1 * 2048 1026047 512000 83 Linux /dev/sda2 1026048 1044381695 521677824 83 Linux /dev/sda3 1044381696 1048575999 2097152 82 Linux swap / Solaris 磁盘 /dev/sdb:107.4 GB, 107374182400 字节,209715200 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 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 DEFAULT transport_url rabbit://openstack:openstack@controller openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone openstack-config --set /etc/cinder/cinder.conf keystone_authtoken www_authenticate_uri http://controller:5000 openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_url http://controller:5000 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 cinder openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 192.168.1.82 openstack-config --set /etc/cinder/cinder.conf lvm volume_driver cinder.volume.drivers.lvm.LVMVolumeDriver openstack-config --set /etc/cinder/cinder.conf lvm volume_group cinder-volumes openstack-config --set /etc/cinder/cinder.conf lvm iscsi_protocol iscsi openstack-config --set /etc/cinder/cinder.conf lvm iscsi_helper lioadm openstack-config --set /etc/cinder/cinder.conf DEFAULT enabled_backends lvm openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_api_servers http://controller:9292 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
# 检查生效的cinder配置
egrep -v "^#|^$" /etc/cinder/cinder.conf grep '^[a-z]' /etc/cinder/cinder.conf
# 实例演示:
[root@openstack02 ~]# egrep -v "^#|^$" /etc/cinder/cinder.conf [DEFAULT] transport_url = rabbit://openstack:openstack@controller auth_strategy = keystone my_ip = 192.168.1.82 enabled_backends = lvm glance_api_servers = http://controller:9292 [backend] [backend_defaults] [barbican] [brcd_fabric_example] [cisco_fabric_example] [coordination] [cors] [database] connection = mysql+pymysql://cinder:cinder@controller/cinder [fc-zone-manager] [healthcheck] [key_manager] [keystone_authtoken] www_authenticate_uri = http://controller:5000 auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = cinder password = cinder [matchmaker_redis] [nova] [oslo_concurrency] lock_path = /var/lib/cinder/tmp [oslo_messaging_amqp] [oslo_messaging_kafka] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_messaging_zmq] [oslo_middleware] [oslo_policy] [oslo_reports] [oslo_versionedobjects] [profiler] [sample_remote_file_source] [service_user] [ssl] [vault] [lvm] volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver volume_group = cinder-volumes iscsi_protocol = iscsi iscsi_helper = lioadm --------------------------------------------------------- [root@openstack02 ~]# grep '^[a-z]' /etc/cinder/cinder.conf transport_url = rabbit://openstack:openstack@controller auth_strategy = keystone my_ip = 192.168.1.82 enabled_backends = lvm glance_api_servers = http://controller:9292 connection = mysql+pymysql://cinder:cinder@controller/cinder www_authenticate_uri = http://controller:5000 auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = cinder password = cinder lock_path = /var/lib/cinder/tmp volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver volume_group = cinder-volumes iscsi_protocol = iscsi iscsi_helper = lioadm
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:

# 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
