    > create database cinder;
    > grant all privileges on cinder.* to 'cinder'@'localhost' identified by '000000';

## 2.获得admin凭证执行管理员命令并创建服务证书 ##

# . /root/admin-openrc
    # openstack user create --domain default --password 000000 cinder
    # openstack role add --project service --user cinder admin

## 4.Controller节点安装块存储组件并配置 ##

[root@controller ~]# yum -y install openstack-cinder 
    
    编辑 /etc/cinder/cinder.conf
    #vi /etc/cinder/cinder.conf
    
    在 “[DEFAULT]” 下添加
    rpc_backend = rabbit
    auth_strategy = keystone
    my_ip = 192.168.100.10
    
    在[database]下添加
    connection = mysql+pymysql://cinder:000000@controller/cinder
    
    在[oslo_messaging_rabbit]部分，配置 “RabbitMQ” 消息队列访问：
    rabbit_host = controller
    rabbit_userid = openstack
    rabbit_password = 000000
    
    在[keystone_authtoken]部分，配置认证服务访问：
    auth_uri = http://controller:5000
    auth_url = http://controller:35357
    memcached_servers = controller:11211
    auth_type = password
    project_domain_name = default
    user_domain_name = default
    project_name = service
    username = cinder
    password = 000000
    
    在 [oslo_concurrency] 部分，配置锁路径：
    lock_path = /var/lib/cinder/tmp

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZseTE1NzQ_size_16_color_FFFFFF_t_70 7]

![在这里插入图片描述][20191125003530429.png]

## 5.初始化块设备服务的数据库 ##

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

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZseTE1NzQ_size_16_color_FFFFFF_t_70 9]

## 6.配置计算节点以使用块设备存储 ##

编辑文件 /etc/nova/nova.conf 并添加如下到其中：
    
    # [root@controller ~]# vi /etc/nova/nova.conf
    
    在[cinder]下添加
    os_region_name = RegionOne

![在这里插入图片描述][20191125003605883.png]

## 7.重启服务并设置开机启动 ##

重启计算API 服务：
    # systemctl restart openstack-nova-api.service
    
    启动块设备存储服务，并将其配置为开机自启：
    #systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
    #systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service

![在这里插入图片描述][20191125003645895.png]

## 8.Compute节点安装并配置一个存储节点，此处用Compute节点代替 ##

#### 1.安装并配置 ####

###### 1.安装支持的工具包LVM： ######

[root@compute ~]# yum -y install lvm2 
    
    启动LVM的metadata服务并且设置该服务随系统启动：
    # systemctl start lvm2-lvmetad.service
    # systemctl enable lvm2-lvmetad.service

###### 2.创建LVM 物理卷 /dev/sdb： ######

首先查看是否存在sdb

# lsblk

首先执行如下命令

创建分区:
    [root@compute ~]# fdisk /dev/sdb

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZseTE1NzQ_size_16_color_FFFFFF_t_70 11]

# pvcreate /dev/sdb1

![在这里插入图片描述][20191125005955278.png]

###### 3.创建 LVM 卷组 cinder-volumes： ######

# vgcreate cinder-volumes /dev/sdb1

###### 3.编辑`/etc/lvm/lvm.conf`文件,并修改 ######

首先查看哪些分区使用了 LVM格式

# lsblk
    
    # vi /etc/lvm/lvm.conf
    在``devices``部分，添加一个过滤器，接受使用lvm的设备：
    
    filter = [ "a/sdb/", "r/.*/"]

![在这里插入图片描述][2019112501010663.png]

#### 2.安装并配置组件(Compute节点) ####

###### 1.安装软件包 ######

# yum -y install openstack-cinder targetcli python-keystone

###### 2.编辑 /etc/cinder/cinder.conf ######

# vi /etc/cinder/cinder.conf #

在[DEFAULT]下添加
    rpc_backend = rabbit
    auth_strategy = keystone
    my_ip = 192.168.100.20   #这里的IP地址是存储节点的ip
    enabled_backends = lvm
    glance_api_servers = http://controller:9292
    
    在[database]下添加
    connection = mysql+pymysql://cinder:000000@controller/cinder
    
    在[oslo_messaging_rabbit]”部分，配置 “RabbitMQ” 消息队列访问：
    rabbit_host = controller
    rabbit_userid = openstack
    rabbit_password = 000000
    
    在[keystone_authtoken]” 部分，配置认证服务访问：
    auth_uri = http://controller:5000
    auth_url = http://controller:35357
    memcached_servers = controller:11211
    auth_type = password
    project_domain_name = default
    user_domain_name = default
    project_name = service
    username = cinder
    password = 000000
    
    添加[lvm]项
    [lvm]
    volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
    volume_group = cinder-volumes
    iscsi_protocol = iscsi
    iscsi_helper = lioadm
    
    在 [oslo_concurrency] 部分，配置锁路径：
    lock_path = /var/lib/cinder/tmp

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZseTE1NzQ_size_16_color_FFFFFF_t_70 12]

![在这里插入图片描述][20191125010311759.png]

#### 3.启动块存储卷服务及其依赖的服务，并将其配置为随系统启动 ####

# systemctl start openstack-cinder-volume.service target.service
    # systemctl enable openstack-cinder-volume.service target.service

## 9.验证操作 ##

# . /root/admin-openrc
    
    列出服务组件以验证是否每个进程都成功启动：
    #cinder service-list

![在这里插入图片描述][20191125010335511.png]

创建卷
    # cinder create --display-name v1 1
    # cinder list
