一、前期准备

1. 软件包准备

• 安装OpenStack Pike Repository
  ~]# yum install centos-release-openstack-pike -y
• 升级软件包
  ~]# yum upgrade
• 安装openstack客户端软件包
  ~]# yum install python-openstackclient -y
• 安装openstack-selinux软件包
  ~]# yum install openstack-selinux -y

2. 安装LVM软件包

~]# yum install lvm2 device-mapper-persistent-data -y
启动服务，并配置其开机自动启动
~]# systemctl enable lvm2-lvmetad.service
~]# systemctl start lvm2-lvmetad.service

3. 创建LVM物理卷

~]# pvcreate /dev/sdb

4. 创建LVM的VG卷组cinder-volumes

~]# vgcreate cinder-volumes /dev/sdb

5. 编辑/etc/lvm/lvm.conf配置文件，确保只允许LVM扫描cinder-volumes

~]# cp /etc/lvm/lvm.conf{,.bak}
~]# vim /etc/lvm/lvm.conf

devices {
...
filter = [ "a/sdb/", "r/.*/"]

二. 安装和配置组件

1. 安装软件包

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

2. 编辑配置文件

~]# cp /etc/cinder/cinder.conf{,.bak}
~]# vim /etc/cinder/cinder.conf

[database]
# ...
connection = mysql+pymysql://cinder:pike@controller/cinder

[DEFAULT]
# ...
transport_url = rabbit://openstack:pike@controller
auth_strategy = keystone
my_ip = 10.6.10.3
enabled_backends = lvm
glance_api_servers = http://controller:9292

[keystone_authtoken]
# ...
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 = pike

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

[oslo_concurrency]
# ...
lock_path = /var/lib/cinder/tmp

三、结束安装

启动openstack-cinder-volume.service和target.service服务，并配置其开机自动启动
~]# systemctl enable openstack-cinder-volume.service target.service
~]# systemctl start openstack-cinder-volume.service target.service

四、验证操作

警告：此步骤在controller节点操作！！

1. 读取admin-openrc环境变量脚本文件

~]# . admin-openrc

2. 列出volume相关服务组件，以验证各个进程的成功加载

~]# openstack volume service list
