控制节点部署

Cinder安装

[root@linux-node1 ~]# yum install -y openstack-cinder

数据库配置

[root@linux-node1 ~]# vim /etc/cinder/cinder.conf
#在 [database] 部分，配置数据库访问。
connection=mysql+pymysql://cinder:cinder@192.168.56.11/cinder
同步数据库
[root@linux-node1 ~]# su -s /bin/sh -c "cinder-manage db sync" cinder
验证数据库状态
[root@linux-node1 ~]# mysql -h 192.168.56.11 -ucinder -pcinder -e "use cinder;show tables;"

Keystone相关配置

[root@linux-node1 ~]# vim /etc/cinder/cinder.conf
[DEFAULT]
auth_strategy=keystone
[keystone_authtoken]
auth_uri = http://192.168.56.11:5000
auth_url = http://192.168.56.11:35357
memcached_servers = 192.168.56.11:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = cinder

RabbitMQ相关配置

[root@linux-node1 ~]# vim /etc/cinder/cinder.conf
[DEFAULT]
transport_url = rabbit://openstack:openstack@192.168.56.11

其它配置

在 [oslo_concurrency] 部分，配置锁路径：
[oslo_concurrency]
lock_path = /var/lib/cinder/tmp

配置Nova以使用块设备存储，注意所有

编辑文件 /etc/nova/nova.conf 并添加如下到其中：

[cinder]
os_region_name = RegionOne

重启nova-api服务

[root@linux-node1 ~]# systemctl restart openstack-nova-api.service

启动cinder服务，并设置为开机自动启动

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

Cinder注册Service和Endpoint

# openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
# openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
# openstack endpoint create --region RegionOne \
  volumev2 public http://192.168.56.11:8776/v2/%\(project_id\)s
# openstack endpoint create --region RegionOne \
  volumev2 internal http://192.168.56.11:8776/v2/%\(project_id\)s
# openstack endpoint create --region RegionOne \
  volumev2 admin http://192.168.56.11:8776/v2/%\(project_id\)s


# openstack endpoint create --region RegionOne \
  volumev3 public http://192.168.56.11:8776/v3/%\(project_id\)s
# openstack endpoint create --region RegionOne \
  volumev3 internal http://192.168.56.11:8776/v3/%\(project_id\)s
 # openstack endpoint create --region RegionOne \
  volumev3 admin http://192.168.56.11:8776/v3/%\(project_id\)s

存储节点配置

对于CentOS环境，默认是已经安装了LVM。如果没有可以使用以下命令安装并启动。

安装 LVM 包：

[root@linux-node1 ~]# yum install -y lvm2 device-mapper-persistent-data

启动LVM的metadata服务并且设置该服务随系统启动：

[root@linux-node1 ~]# systemctl enable lvm2-lvmetad.service
[root@linux-node1 ~]# systemctl start lvm2-lvmetad.service

把/dev/sdb创建为LVM的物理卷：

[root@linux-node2 ~]# pvcreate /dev/sdb
  Physical volume "/dev/sdb" successfully created

创建名为cinder-volumes的逻辑卷组

[root@linux-node2 ~]# vgcreate cinder-volumes /dev/sdb
  Volume group "cinder-volumes" successfully created
[root@linux-node2 ~]# vim /etc/lvm/lvm.conf
    在``devices``部分，添加一个过滤器，只接受``/dev/sdb``设备，拒绝其他所有设备：
    devices {
    ...
    filter = [ "a/sdb/", "r/.*/"]
    filter = [ "a/sda/", "a/sdb/", "r/.*/"]
    filter = [ "a/sda/", "r/.*/"]

存储节点安装

存储节点安装和控制节点类型，还是分为两步：

  1. 软件安装。
  2. 从控制节点SCP配置文件。

安装isci-target和cinder

[root@linux-node2 ~]# yum install -y openstack-cinder targetcli python-keystone

同步控制节点配置文件

由于存储节点大多数配置和控制节点相同，可以直接使用控制节点配置好的cinder.conf。再此基础上进行小的变动。

[root@linux-node1 ~]# scp /etc/cinder/cinder.conf 192.168.56.12:/etc/cinder/

设置Cinder后端驱动

[root@linux-node2 ~]# vim /etc/cinder/cinder.conf
[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm
volume_backend_name=iSCSI-Storage

在 [DEFAULT] 部分，启用 LVM 后端：
[DEFAULT]
...
enabled_backends = lvm


[DEFAULT]
glance_api_servers = http://192.168.56.11:9292

启动块存储卷服务及其依赖的服务，并将其配置为随系统启动： # systemctl enable openstack-cinder-volume.service target.service # systemctl start openstack-cinder-volume.service target.service
