OpenStack的部署T版（七）——cinder模块
一、创建数据库实例和角色
CT节点
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、创建用户、修改配置文件
创建cinder用户,密码设置为CINDER_PASS
openstack user create --domain default --password CINDER_PASS cinder
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
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 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/sdb
vgcreate cinder-volumes /dev/sdb
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/sdb/","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 192.168.100.30
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
开启cinder卷服务
systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service
四、ct节点查看卷列表
openstack volume service list
