一、Cinder控制节点

1、创建Cinder数据库

mysql> CREATE DATABASE cinder;
mysql> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
  IDENTIFIED BY 'cinder';
mysql> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
  IDENTIFIED BY 'cinder';
mysql>  flush privileges;

2、安装配置cinder

yum install openstack-cinder python-cinderclient nfs-utils
vim /etc/cinder/cinder.conf

[DEFAULT]
my_ip = 192.168.100.100
auth_strategy = keystone
log_dir = /var/log/cinder
state_path = /var/lib/cinder
glance_api_servers = http://controller:9292
transport_url = rabbit://openstack:openstack@controller
enabled_backends = lvm,nfs

[database]
connection = mysql+pymysql://cinder:cinder@controller/cinder

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = cinder

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp

[nfs]  
nfs_shares_config=/etc/cinder/nfs_shares
nfs_mount_point_base = $state_path/mnt
nfs_sparsed_volumes=true  
volume_driver=cinder.volume.drivers.nfs.NfsDriver  
volume_backend_name=nfs01

vim /etc/nova/nova.conf

[cinder]
os_region_name = RegionOne

3、同步数据库：

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

4、创建Cinder的项目，角色，用户,注册Cinder的三种API

openstack user create --domain default --password=cinder cinder
openstack role add --project service --user cinder admin
openstack service create --name cinderv2   --description "OpenStack Block Storage" volumev2
openstack service create --name cinderv3   --description "OpenStack Block Storage" volumev3
openstack endpoint create --region RegionOne   volumev2 public http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev2 internal http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev2 admin http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev3 public http://controller:8776/v3/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev3 internal http://controller:8776/v3/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev3 admin http://controller:8776/v3/%\(project_id\)s

5、启动服务：

systemctl restart openstack-nova-api.service    #前面修改了nova配置文件要重启下nova-api
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

二、Cinder存储节点

本示例在一台服务器上

1、安装配置LVM

yum install -y lvm2
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service

2、nfs安装配置

yum install -y nfs-utils rpcbind
nfs-utils ：包括基本的NFS命令与监控程序
rpcbind或portmap：支持安全NFS RPC服务的连接

lvcreate -L 50G -n cindervg cl #建lv
mkfs.xfs -f /dev/cl/cindervg #格式化
mkdir /cinder/data
mount /dev/cl/cindervg /cinder/data
vim /etc/fstab
配置NFS目录的访问权限、用户映射
vim /etc/exports
/cinder/data *(rw,no_root_squash)
chown cinder:cinder /cinder/data
chmod 777 /cinder/data

3、启动服务

systemctl enable rpcbind
systemctl enable nfs
systemctl restart rpcbind
systemctl restart nfs

4、配置

在/etc/cinder/nfs_shares文件中配置路径
vim /etc/cinder/nfs_shares
master:/cinder/data
权限设置
chown root:cinder /etc/cinder/nfs_shares
vim /etc/cinder/cinder.conf，在上面已经配置

[nfs]  
nfs_shares_config=/etc/cinder/nfs_shares
nfs_sparsed_volumes=true  
volume_driver=cinder.volume.drivers.nfs.NfsDriver  
volume_backend_name=nfs  

启动Cinder卷服务

systemctl enable openstack-cinder-volume.service target.service
systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service openstack-cinder-volume.service target.service
