传统公司部署OpenStack（t版）简易介绍（七）——cinder模块部署

• 一、创建数据库实例和角色
• 二、创建用户、修改配置文件
• 三、在计算节点c2配置Cinder
• 四、ct节点查看卷列表
• 总结

一、创建数据库实例和角色

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、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

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sdb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

总结

• 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
