须知:  

  根据上次基础环境部署,已经可以使用dashboard创建和管理虚拟机了。在生产环境中,所有虚拟机磁盘镜像是存在NAS存储架构中的,这样做保证了数据的可靠性,提高性能,可动态迁移。在早期的Openstack版本,用来卷存储的服务是nova-volume,是Nova的一部分,从F版本后,已经独立出来一个核心组件Cinder,首先你要知道Cinder本身不是来提供存储的,它是为后端的存储服务器,提供一个统一的Api来管理,它不去考虑后端存储是什么样的架构,它只需知道后端存储技术使用什么协议来工作的,这样存储技术有:LVM、NFS、IP-SAN、FC-SAN、分布式文件系统等,还包括硬件存储厂商NetApp、EMC、IBM都已经支持Openstack。通过这个管理接口,我们可以轻松的管理云硬盘。

下面就来部署下Cinder,后端存储技术采用LVM卷和iSCSI共享存储,也是Cinder默认的块存储。

Configure Controller Node


一、块存储Cinder服务安装与配置

1.安装块存储服务控制器

# yum install openstack-cinder

2.配置数据库

# openstack-config --set /etc/cinder/cinder.conf database connection mysql://cinder:CINDER_DBPASS@controller/cinder
3.创建数据库
# mysql -u root -p
mysql> CREATE DATABASEcinder;
mysql> GRANT ALLPRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
IDENTIFIED BY'CINDER_DBPASS';
mysql> GRANT ALLPRIVILEGES ON cinder.* TO 'cinder'@'%' \
IDENTIFIED BY'CINDER_DBPASS';
mysql> exit;
4.导入数据库
# cinder-manage db sync
5.创建用户并添加到角色admin
# keystone user-create --name=cinder --pass=cinder --email=cinder@example.com
# keystone user-role-add --user=cinder --tenant=service --role=admin

6.配置token认证信息



openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_uri http://controller:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_host controller
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_protocol http
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_port 35357
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_user cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_tenant_name service
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_password cinder



7.配置消息队列qpid



openstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend cinder.openstack.common.rpc.impl_qpid
openstack-config --set /etc/cinder/cinder.conf DEFAULT qpid_hostname controller
openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_host controller



 7.1修改/etc/cinder/cinder.conf

[DEFAULT]
 osapi_volume_listen=0.0.0.0
 state_path=/var/lib/cinder
 volumes_dir=/var/lib/cinder/volumes

8.创建cinder服务标识

# keystone service-create --name=cinder --type=volume --description="OpenStack Block Storage"
# keystone service-create --name=cinderv2 --type=volumev2 --description="OpenStack Block Storagev2"

9.创建Cinder API版本1和版本2接口URL


# keystone endpoint-create \
--service-id=$(keystone service-list | awk '/ volume / {print $2}') \
--publicurl=http://controller:8776/v1/%\(tenant_id\)s\
--internalurl=http://controller:8776/v1/%\(tenant_id\)s\
--adminurl=http://controller:8776/v1/%\(tenant_id\)s


# keystone endpoint-create \
--service-id=$(keystone service-list | awk '/ volumev2 / {print $2}') \
--publicurl=http://controller:8776/v2/%\(tenant_id\)s\
--internalurl=http://controller:8776/v2/%\(tenant_id\)s\
--adminurl=http://controller:8776/v2/%\(tenant_id\)s


10.重启服务并设置自启动



service openstack-cinder-api start
 service openstack-cinder-scheduler start
 service openstack-cinder-volume start
 service tgtd start
 chkconfig openstack-cinder-volume on
 chkconfig tgtd on
 chkconfig openstack-cinder-api on
 chkconfig openstack-cinder-scheduler on

Configure Storage Node


二、添加一台存储节点,并添加一块硬盘

1.ip地址设置为192.168.1.33

2.控制节点和存储节点添加对应host记录

192.168.1.33 storage

3.创建LVM卷

# pvcreate /dev/sdb

# vgcreate cinder-volumes/dev/sdb

4.安装块存储服务

# yum install openstack-cinder scsi-target-utils

5.配置token认证信息


openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken 
auth_urihttp://controller:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_host controller
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_protocol http
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_port 35357
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_user cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken 
admin_tenant_name service
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_password cinder


6.配置消息队列qpid



openstack-config --set /etc/cinder/cinder.conf DEFAULT 
rpc_backendcinder.openstack.common.rpc.impl_qpid
openstack-config --set /etc/cinder/cinder.conf DEFAULT qpid_hostname controller



7.配置连接数据库

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

8.配置glance服务位置

# openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_host controller

9.配置iSCSI目标发现块存储,使用iSCSI协议时使用

# vi /etc/tgt/targets.conf
include /etc/cinder/volumes/*

10.启动服务并设置自启动



service openstack-cinder-volume start
service tgtd start
chkconfig openstack-cinder-volume on
chkconfig tgtd on



11.创建一个10G的卷

# source admin-openrc.sh

# cinder create--display-name myVolume 10

12.查看创建的卷,下面是我实验后的

openstack 存储池和卷 openstack存储服务_数据库

13.登录Horizon查看

配置完成后,dashboard上面会生成一个云硬盘选项
