一、創建數據庫實例和角色

mysql -uroot -p CREATE DATABASE cinder; GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS'; GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CINDER_DBPASS'; flush privileges; exit

二、創建用戶、修改配置文件

#創建cinder用戶,密碼設置為CINDER_PASS openstack user create --domain default --password CINDER_PASS cinder#把cinder用戶添加到service服務中，并授予admin權限 openstack role add --project service --user cinder admin#cinder有v2和v3兩個并存版本的API，所以需要創建兩個版本的service實例 openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2 openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3 #給v2和v3版本的api創建endpoint openstack endpoint create --region RegionOne volumev2 public http://ct:8776/v2/%\(project_id\)s openstack endpoint create --region RegionOne volumev2 internal http://ct:8776/v2/%\(project_id\)s openstack endpoint create --region RegionOne volumev2 admin http://ct:8776/v2/%\(project_id\)s openstack endpoint create --region RegionOne volumev3 public http://ct:8776/v3/%\(project_id\)s openstack endpoint create --region RegionOne volumev3 internal http://ct:8776/v3/%\(project_id\)s openstack endpoint create --region RegionOne volumev3 admin http://ct:8776/v3/%\(project_id\)s#yum 安裝cinder 服務 yum -y install openstack-cinder#修改cinder 配置文件 cp /etc/cinder/cinder.conf{,.bak} grep -Ev '#|^$' /etc/cinder/cinder.conf.bak>/etc/cinder/cinder.conf openstack-config --set /etc/cinder/cinder.conf database connection mysql+pymysql://cinder:CINDER_DBPASS@ct/cinder openstack-config --set /etc/cinder/cinder.conf DEFAULT transport_url rabbit://openstack:RABBIT_PASS@ct openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone openstack-config --set /etc/cinder/cinder.conf keystone_authtoken www_authenticate_uri http://ct:5000 openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_url http://ct:5000 openstack-config --set /etc/cinder/cinder.conf keystone_authtoken memcached_servers ct:11211 openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_type password openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_domain_name default openstack-config --set /etc/cinder/cinder.conf keystone_authtoken user_domain_name default openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_name service openstack-config --set /etc/cinder/cinder.conf keystone_authtoken username cinder openstack-config --set /etc/cinder/cinder.conf keystone_authtoken password CINDER_PASS openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 192.168.100.10 openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp#同步cinder數據庫(填充塊存儲數據庫) su -s /bin/sh -c "cinder-manage db sync" cinder#修改 Nova 配置文件，并重啟服務 openstack-config --set /etc/nova/nova.conf cinder os_region_name RegionOne systemctl restart openstack-nova-api.service#配置Cinder服務 systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service#配置控制節點驗證 cinder service-list

三、在計算節點c2配置Cinder

yum -y install openstack-cinder targetcli python-keystone yum -y install lvm2 device-mapper-persistent-data systemctl enable lvm2-lvmetad.service systemctl start lvm2-lvmetad.service#創建lvm物理卷和卷組 pvcreate /dev/sdb vgcreate cinder-volumes /dev/sdb#修改lvm配置文件(指定使用sdb磁盤） vim /etc/lvm/lvm.conf 141行，取消注釋，修改filter規則，如下： filter = [ "a/sdb/","r/.*/" ] ## a表示允許，r表示拒絕 ## 只允許lvm服務訪問sdc中的數據，不允許lvm服務訪問其他磁盤，這也間接實現了openstack創建的虛擬機只能訪問sdb中的數據，不能訪問其他磁盤 ## 設置只允許實例訪問sdc邏輯卷中的數據；如果不配置的話，本機的其他服務也有可能會訪問sdc邏輯卷中的數據#重啟lvm服務 systemctl restart lvm2-lvmetad.service#配置cinder模塊 cp /etc/cinder/cinder.conf{,.bak} grep -Ev '#|^$' /etc/cinder/cinder.conf.bak>/etc/cinder/cinder.conf openstack-config --set /etc/cinder/cinder.conf database connection mysql+pymysql://cinder:CINDER_DBPASS@ct/cinder openstack-config --set /etc/cinder/cinder.conf DEFAULT transport_url rabbit://openstack:RABBIT_PASS@ct openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 192.168.100.30 openstack-config --set /etc/cinder/cinder.conf DEFAULT enabled_backends lvm openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_api_servers http://ct:9292 openstack-config --set /etc/cinder/cinder.conf keystone_authtoken www_authenticate_uri http://ct:5000 openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_url http://ct:5000 openstack-config --set /etc/cinder/cinder.conf keystone_authtoken memcached_servers ct:11211 openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_type password openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_domain_name default openstack-config --set /etc/cinder/cinder.conf keystone_authtoken user_domain_name default openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_name service openstack-config --set /etc/cinder/cinder.conf keystone_authtoken username cinder openstack-config --set /etc/cinder/cinder.conf keystone_authtoken password CINDER_PASS openstack-config --set /etc/cinder/cinder.conf lvm volume_driver cinder.volume.drivers.lvm.LVMVolumeDriver openstack-config --set /etc/cinder/cinder.conf lvm volume_group cinder-volumes openstack-config --set /etc/cinder/cinder.conf lvm target_protocol iscsi openstack-config --set /etc/cinder/cinder.conf lvm target_helper lioadm openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp#開啟cinder卷服務 systemctl enable openstack-cinder-volume.service target.service systemctl start openstack-cinder-volume.service target.service

四、ct節點查看卷列表

openstack volume service list

總結

• Cinder配置思路：
  • 創建管理、對接的用戶、密碼、服務和endpoint
  • 修改配置文件：
  • 主要內容為 向keystone對接認證授權、組件之間通訊模塊、配置所在的域等
  • 配置計算節點中虛擬機所用的卷
