OpenStack Train版-13.安装块存储服务cinder（控制节点）

Cinder的核心功能是对卷的管理，允许对卷、卷的类型、卷的快照、卷备份进行处理。它为后端不同的存储设备提供给了统一的接口，不同的块设备服务厂商在Cinder中实现其驱动，可以被Openstack整合管理，nova与cinder的工作原理类似。

OpenStack块存储服务为实例通过不同后台提供块存储设备。块存储 API 和调度服务运行在控制节点。volume 服务运行在一个或多个存储节点。cinder为实例提供本地存储或则 SAN/NAS后台适当的驱动。

安装cindoer块存储服务(控制节点192.168.0.10)
创建cinder数据库并授权

mysql -u root

create database cinder;

grant all privileges on cinder.* to 'cinder'@'%' identified by 'CINDER_DBPASS';

grant all privileges on cinder.* to 'cinder'@'localhost' identified by 'CINDER_DBPASS';

flush privileges;

创建cinder用户,密码设置为CINDER_PASS

source ~/admin-openrc

openstack user create --domain default --password CINDER_PASS cinder

admin向cinder用户添加角色

openstack role add --project service --user cinder admin

创建cinderv2和cinderv3服务实体

openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2

openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3

创建块存储服务API端点

块存储服务需要每个服务实体的端点

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

安装cinder软件包并修改配置文件

yum install openstack-cinder -y

编辑配置文件/etc/cinder/cinder.conf

cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak

grep -Ev '#|^$' /etc/cinder/cinder.conf.bak>/etc/cinder/cinder.conf

openstack-config --set /etc/cinder/cinder.conf database connection mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder

openstack-config --set /etc/cinder/cinder.conf DEFAULT transport_url rabbit://openstack:RABBIT_PASS@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_PASS

openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 192.168.0.10

openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp

填充块存储数据库

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

配置计算服务以使用块存储

编辑配置文件/etc/nova/nova.conf

openstack-config --set /etc/nova/nova.conf cinder os_region_name RegionOne

重启nova计算和cinder块存储服务并设置开机自启动

systemctl restart openstack-nova-api.service

systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service

systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service

控制节点验证

[root@controller ~]# cinder service-list

+------------------+------------+------+---------+-------+----------------------------+---------+-----------------+---------------+

| Binary | Host | Zone | Status | State | Updated_at | Cluster | Disabled Reason | Backend State |
