kavin 虚拟化 2018-05-10 2901浏览 0

 

1.Cinder安装

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

2.数据库配置

[root@linux-node1 ~]# vim /etc/cinder/cinder.conf

#[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;"

3.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

4.RabbitMQ相关配置

[root@linux-node1 ~]# vim /etc/cinder/cinder.conf

[DEFAULT]

transport_url = rabbit://openstack:openstack@192.168.56.11

5.其它配置

[oslo_concurrency] 部分,配置锁路径:

[oslo_concurrency]

lock_path = /var/lib/cinder/tmp

6.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

7.重启nova-api服务

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

8.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

9.Cinder注册ServiceEndpoint

# 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LVMmetadata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

/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

    ``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-targetcinder

[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

[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
