A13 openstack架构实战-控制节点cinder块存储服务部署

cinder-volume和nova-compute类似，nova-compute并不能管理虚拟机，而是通过libvirt来对虚拟机进行管理，cinder-volume也是如此，他并不是自己能够提供存储，他是一调用的方法，调用nfs，lvm，glusterfs,ceph等存储进行使用

cinder-api： 接收外部的api请求

cinder-volume(可以使用多个方法)：提供存储空间

cinder-scheduler：调度器，决定将要分配的空间由哪一个cinder-volume提供

cinder-backup：备份创建的卷

部署cinder块存储服务：（在控制节点上进行演示）

一：创建对应数据库，并授权

MariaDB [(none)]>  CREATE DATABASE cinder;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]>  GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost'
    ->   IDENTIFIED BY 'huayun';
Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%'    IDENTIFIED BY 'huayun';
Query OK, 0 rows affected (0.00 sec)

二：在keystone上进行创建用户，并授权

1：创建cinder用户

[root@controller01 ~]# openstack user create --domain default --password-prompt cinder

2：将admin角色进行绑定到cinder用户中去：

[root@controller01 ~]# openstack role add --project service --user cinder admin

3：创建cinderv2和cinderv3服务验证：

创建cinder服务：
[root@controller01 ~]# openstack service create --name cinderv2
>   --description "OpenStack Block Storage" volumev2
[root@controller01 ~]# openstack service create --name cinderv3
>   --description "OpenStack Block Storage" volumev3

4：创建块存储服务API端点：

[root@controller01 ~]# openstack endpoint create --region RegionOne
>   volumev2 public http://controller01:8776/v2/%(project_id)s
[root@controller01 ~]# openstack endpoint create --region RegionOne  

volumev2 internal http://controller01:8776/v2/%(project_id)s

[root@controller01 ~]# openstack endpoint create --region RegionOne
>   volumev2 admin http://controller01:8776/v2/%(project_id)s

[root@controller01 ~]# openstack endpoint create --region RegionOne
>   volumev3 public http://controller01:8776/v3/%(project_id)s

[root@controller01 ~]# openstack endpoint create --region RegionOne
>   volumev3 internal http://controller01:8776/v3/%(project_id)s

[root@controller01 ~]#  openstack endpoint create --region RegionOne
>   volumev3 admin http://controller01:8776/v3/%(project_id)s

5：安装软件包

[root@controller01 ~]# yum install openstack-cinder -y

6：修改配置文件：

[root@controller01 ~]# vim /etc/cinder/cinder.conf

a.数据库连接修改：

[database]
connection = mysql+pymysql://cinder:huayun@controller01/cinder

b.在该[DEFAULT]部分中，配置RabbitMQ 消息队列访问：

[DEFAULT]
transport_url = rabbit://openstack:huayun@controller01

c.在[DEFAULT]和[keystone_authtoken]部分中，配置身份服务访问：

[DEFAULT]
........
auth_strategy = keystone

glance_api_servers = http://10.100.214.202:9292

[keystone_authtoken]
auth_uri = http://controller01:5000
auth_url = http://controller01:5000
memcached_servers = controller01:11211
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = huayun

d.在该[DEFAULT]部分中，配置my_ip选项以使用控制器节点的管理接口IP地址：

[DEFAULT]

my_ip = 10.100.201.201

e.在该[oslo_concurrency]部分中，配置锁定路径：

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

7：同步数据库

[root@controller01 ~]# su -s /bin/sh -c "cinder-manage db sync" cinder
检测数据库是否创建：

[root@controller01 ~]# mysql -uroot -phuayun cinder -e "show tables;"

三：配置控制节点de计算服务使用cinder

[root@controller01 ~]# vim /etc/nova/nova.conf

[cinder]
os_region_name = RegionOne

启动计算服务：

[root@controller01 ~]# systemctl restart openstack-nova-api.service

启动cinder服务：

[root@controller01 ~]# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
[root@controller01 ~]# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

检测：

[root@controller01 ~]# cinder service-list
