Openstack云平台搭建课程七·存储服务Cinder

这是搭建Openstack云平台的第七堂课,主要讲述存储组件cinder的配置过程。Cinder负责管理Openstack所有存储资源,因此要求磁盘性能有保障。

创建数据库用户

mysql -uroot -pMariadb123
create database cinder;
grant all privileges on cinder.* to 'cinder'@'localhost' identified by 'Cinder123';
grant all privileges on cinder.* to 'cinder'@'%' identified by 'Cinder123';
flush privileges;
exit

配置cinder服务凭证

创建cinder服务凭证

# source /opt/scripts/admin
# 开始创建用户
openstack user create \
--domain default \
--password-prompt cinder

输入密码(Cinder123)后继续:

openstack role add \
--project service \
--user cinder admin
openstack service create \
--name cinderv2 \
--description "OpenStack Block Storage" volumev2
openstack service create \
--name cinderv3 \
--description "OpenStack Block Storage" volumev3

创建endpoint

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

配置控制节点上的服务

安装cinder

yum -y install openstack-cinder

配置cinder

修改配置/etc/cinder/cinder.conf

[DEFAULT]
my_ip = 10.10.100.150
auth_strategy = keystone
log_dir = /var/log/cinder
transport_url = rabbit://openstack:Openstack123@controller:5672
#如果使用ceph存储,请取消以下注释
#enabled_backends = ceph
#glance_api_servers = http://controller:9292
#osapi_volume_listen = $my_ip
#osapi_volume_listen_port = 8776
#state_path = /var/lib/cinder

[ceph]
#如果使用ceph,取消如下注释,并注释后面lvm段中的所有内容
#volume_driver = cinder.volume.drivers.rbd.RBDDriver
#rbd_pool = volumes
#rbd_ceph_conf = /etc/ceph/ceph.conf
#rbd_flatten_volume_from_snapshot = False
#rbd_max_clone_depth = 5
#rbd_store_chunk_size = 4
#rados_connect_timeout = -1
#glance_api_version = 2
#rbd_user = cinder
#rbd_secret_uuid = {uuid}

[database]
connection = mysql+pymysql://cinder:Cinder123@controller/cinder

[keystone_authtoken]
#auth_uri = http://controller:5000
www_authenticate_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = cinder
password = Cinder123

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
#lock_path = $state_path/tmp

初始化cinder数据

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

配置nova

修改配置/etc/nova/nova.conf

[cinder]
os_region_name = RegionOne

启动应用

systemctl restart openstack-nova-api
systemctl enable openstack-cinder-api openstack-cinder-scheduler
systemctl start openstack-cinder-api openstack-cinder-scheduler

配置存储节点上的服务

启用lvm

一般情况下,系统默认已经启动lvm服务,无需以下操作。

systemctl enable lvm2-lvmetad; systemctl start lvm2-lvmetad

配置专用存储块

# 找到要添加的存储块
fdisk -l
# 创建pv
pvcreate /dev/sdb
# 创建vg
vgcreate cinder-volumes /dev/sdb

安装cinder

yum -y install openstack-cinder targetcli python-keystone

配置cinder

修改配置/etc/cinder/cinder.conf

[DEFAULT]
my_ip = 10.10.100.151
auth_strategy = keystone
enabled_backends = lvm
glance_api_servers = http://controller:9292
transport_url = rabbit://openstack:Openstack123@controller:5672

[database]
connection = mysql+pymysql://cinder:Cinder123@controller/cinder

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = cinder
password = Cinder123

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

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

启动应用

systemctl enable openstack-cinder-volume target
systemctl start openstack-cinder-volume target

在控制节点上验证存储

openstack volume service list
