Openstack I版 结合 Ceph 分布式存储 部署安装(四)

配置Cinder块设备存储

安装cinder组件

yum install openstack-cinder -y

备份cinder配置文件

mv /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak

创建cinder配置文件
vi /etc/cinder/cinder.conf

注意rbd_secret_uuid为前面实际创建的值,笔者的环境中是: AQCEWRpVGDOsCBAAuGIEzp/FkCc6KPQSaFGAbw==

修改cinder配置文件权限

chown -R root:cinder /etc/cinder/cinder.conf

同步导入cinder数据库表

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

创建cinder用户、角色、端点服务

keystone user-create --name=cinder --pass=CINDER_PASS [email protected]
keystone user-role-add --user=cinder --tenant=service --role=admin
keystone service-create --name=cinder --type=volume --description="OpenStack Block Storage"
keystone endpoint-create \
--service-id=$(keystone service-list | awk '/ volume / {print $2}') \ --publicurl=http://controller:8776/v1/%\(tenant_id\)s \ --internalurl=http://controller:8776/v1/%\(tenant_id\)s \ --adminurl=http://controller:8776/v1/%\(tenant_id\)s keystone service-create --name=cinderv2 --type=volumev2 --description="OpenStack Block Storage v2"
keystone endpoint-create \
--service-id=$(keystone service-list | awk '/ volumev2 / {print $2}') \ --publicurl=http://controller:8776/v2/%\(tenant_id\)s \ --internalurl=http://controller:8776/v2/%\(tenant_id\)s \ --adminurl=http://controller:8776/v2/%\(tenant_id\)s

修改volumes的cephx密钥权限

chown -R cinder:cinder /etc/ceph/ceph.client.volumes.keyring

启动cinder相关服务

service openstack-cinder-api start
service openstack-cinder-scheduler start
service openstack-cinder-volume start
chkconfig openstack-cinder-api on
chkconfig openstack-cinder-scheduler on
chkconfig openstack-cinder-volume on

Cinder创建volume硬盘卷验证

[root@controller ~]# cinder create --display-name test 1
