一、实验
1.环境
(1) 主机
表1 主机
|------------|-------|-----------------|-----|
| 主机 | 架构 | IP | 备注 |
| controller | 控制节点 | 192.168.204.210 | 已部署 |

OpenStack Docs: OpenStack Installation Guide for Red Hat Enterprise Linux and CentOS
(3)网络
①存储节点1 ping 控制节点
②存储节点1 ping 计算节点1 与 计算节点2
(4) 时间同步
① 存储节点1
bash
[root@storage01 ~]# yum install -y chrony
bash
[root@storage01 ~]# vim /etc/chrony.conf
[root@storage01 ~]# systemctl restart chronyd.service && systemctl enable chronyd.service
③测试
bash
[root@controller ~]# date
[root@compute01 ~]# date
[root@compute02 ~]# date
[root@storage01 ~]# date
(5) 控制节点查看(目前已部署controller、compute01与compute02)
bash
# neutron agent-list
2.安装并配置控制节点
(1)创建数据库
①用数据库连接客户端 (生产环境需要密码)
bash
$ mysql -u root -p
② 创建 cinder 数据库
bash
CREATE DATABASE cinder;
③ 允许 cinder 数据库合适的访问权限(用合适的密码替换 CINDER_DBPASS)
bash
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
IDENTIFIED BY 'CINDER_DBPASS';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
IDENTIFIED BY 'CINDER_DBPASS';
(2)创建一个 cinder 用户
bash
$ openstack user create --domain default --password-prompt cinder
(3)添加 admin 角色到 cinder 用户上
bash
$ openstack role add --project service --user cinder admin
(4)创建 cinder 和 cinderv2 服务实体
bash
$ openstack service create --name cinder \
--description "OpenStack Block Storage" volume
$ openstack service create --name cinderv2 \
--description "OpenStack Block Storage" volumev2
(5)查看
bash
# openstack service list |grep cinder
(6)创建块设备存储服务的 API 入口点
bash
$ openstack endpoint create --region RegionOne \
volume public http://controller:8776/v1/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
volume internal http://controller:8776/v1/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
volume admin http://controller:8776/v1/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
volumev2 public http://controller:8776/v2/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
volumev2 internal http://controller:8776/v2/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
volumev2 admin http://controller:8776/v2/%\(tenant_id\)s
(7)查看
bash
# openstack endpoint list |grep cinder

bash
[oslo_concurrency]
...
lock_path = /var/lib/cinder/tmp
⑤ 备份复制
(10) 初始化块设备服务的数据库(忽略输出中任何不推荐使用的信息)
bash
# su -s /bin/sh -c "cinder-manage db sync" cinder
(11)配置计算节点以使用块设备存储
编辑文件 /etc/nova/nova.conf
bash
[cinder]
os_region_name = RegionOne
(12)重启服务
①重启计算API 服务
bash
# systemctl restart openstack-nova-api.service
②启动块设备存储服务,并将其配置为开机自启
bash
# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
(13)登录系统
(14)已新增卷的模块
