Openstack（Ocata版本）部署总结第七章：块存储

（1）控制节点
1、配置数据库

$ mysql -u root -p
MariaDB [(none)]> CREATE DATABASE cinder;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
  IDENTIFIED BY 'CINDER_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
  IDENTIFIED BY 'CINDER_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'controller' \
  IDENTIFIED BY 'CINDER_DBPASS';

2、创建服务实体和API端点

$ . admin-openrc
$ openstack user create --domain default --password-prompt cinder
User Password:
Repeat User Password:
$ 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

$ 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

3、安装并配置服务

# yum install openstack-cinder

# vim /etc/cinder/cinder.conf
[database]
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder
[DEFAULT]
transport_url = rabbit://openstack:RABBIT_PASS@controller
auth_strategy = keystone
my_ip = 10.0.0.11     这里为controller的IP地址
[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 = CINDER_PASS
[oslo_concurrency]
lock_path = /var/lib/cinder/tmp

# su -s /bin/sh -c "cinder-manage db sync" cinder
# vim /etc/nova/nova.conf
[cinder]
os_region_name = RegionOne

4、启动服务并加入开机自启

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

（2）存储节点
1、安装lvm服务并启动

# yum install lvm2
# systemctl enable lvm2-lvmetad.service
# systemctl start lvm2-lvmetad.service

2、创建lvm逻辑卷/dev/sdb

# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created
# vgcreate cinder-volumes /dev/sdb
Volume group "cinder-volumes" successfully created

3、配置LVM过滤

# vim /etc/lvm/lvm.conf
devices {
...
filter = [ "a/sdb/", "r/.*/"]
这里如果出错的话，建议对挂载的硬盘重新做分区、格式化

4、安装cinder服务

# yum install openstack-cinder targetcli python-keystone
# vim /etc/cinder/cinder.conf
[database]
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder
[DEFAULT]
transport_url = rabbit://openstack:RABBIT_PASS@controller
auth_strategy = keystone
my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS   这里修改为Cinder节点的IP
enabled_backends = lvm
glance_api_servers = http://controller:9292
[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 = CINDER_PASS
[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
[lvm]   这个标签默认是没有的，加到最后即可
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

5、启动服务并加到开机自启

# systemctl enable openstack-cinder-volume.service target.service
# systemctl start openstack-cinder-volume.service target.service

6、验证

$ . admin-openrc
$ openstack volume service list

这里看到状态为enabled 和 up即为正确。
