一、创建数据库实例和角色
mysql -uroot -p1
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、创建用户、修改配置文件
#① 创建cinder用户,密码设置为CINDER_PASS
openstack user create --domain default --password CINDER_PASS cinder
#② 把cinder用户添加到service服务中，并授予admin权限
openstack role add --project service --user cinder admin
#③ cinder有v2和v3两个并存版本的API，所以需要创建两个版本的service实例
openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
给v2和v3版本的api创建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 安装cinder 服务
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 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 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 192.168.61.55 #修改为 ct_IP地址
openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp
#查看配置文件
[root@ct cinder]# cat cinder.conf

同步cinder数据库(填充块存储数据库)
su -s /bin/sh -c "cinder-manage db sync" cinder
修改 Nova 配置文件，并重启服务。
openstack-config --set /etc/nova/nova.conf cinder os_region_name RegionOne
systemctl restart openstack-nova-api.service
配置Cinder服务
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
配置控制节点验证
cinder service-list
三、在计算节点c2配置Cinder（存储节点）
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
创建lvm物理卷和卷组
pvcreate /dev/sdc
vgcreate cinder-volumes /dev/sdc
● 修改lvm配置文件(指定使用sdc磁盘）
vim /etc/lvm/lvm.conf
● 141行，取消注释，修改filter规则，如下：
filter = [ "a/sdc/","r/.*/" ]
#a表示允许，r表示拒绝
#只允许lvm服务访问sdc中的数据，不允许lvm服务访问其他磁盘，这也间接实现了openstack创建的虚拟机只能访问sdb中的数据，不能访问其他磁盘
#设置只允许实例访问sdc逻辑卷中的数据；如果不配置的话，本机的其他服务也有可能会访问sdc逻辑卷中的数据
重启lvm服务
systemctl restart lvm2-lvmetad.service
配置cinder模块
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 192.168.61.77
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
【修改如下】
[DEFAULT]
transport_url = rabbit://openstack:RABBIT_PASS@ct
auth_strategy = keystone
my_ip = 192.168.61.77
enabled_backends = lvm
glance_api_servers = http://ct:9292

target_protocol = iscsi #pv使用的是iscsi协议，可以提供块存储服务
target_helper = lioadm #iscsi管理工具
#volume_backend_name=Openstack-lvm #选择：当后端有多个不同类型的存储时，可以在openstack中调用指定的存储；
给当前存储指定个名称，用于后期区分多个不同的存储
开启cinder卷服务
systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service
查看卷列表
openstack volume service list
小结：
Cinder配置思路：
创建管理、对接的用户、密码、服务和endpoint
修改配置文件：
主要内容为 向keystone对接认证授权、组件之间通讯模块、配置所在的域等
配置计算节点中虚拟机所用的卷
