前言

cinder服务在OpenStack中不是必须的，cinder就是提供一个volume存储卷的功能，创建一个卷然后绑定到启动的实例上面去，没他我们照旧可以使用实例没啥影响。但是既然官方文档中写了那就部署上吧。

一、controller节点

1、数据库

# mysql -uroot -pXylong_000

MariaDB [(none)]> CREATE DATABASE cinder;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY '123';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY '123';Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> exit

2、创建身份认证

#source admin-openrc 
# openstack user create --domain default --password-prompt cinder
# openstack role add --project service --user cinder admin

创建服务

# openstack service create --name cinderv2   --description "OpenStack Block Storage" volumev2
# openstack service create --name cinderv3   --description "OpenStack Block Storage" volumev3

创建三类endpoint访问端口

# 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

3、安装软件

# yum install openstack-cinder

4、修改配置文件

# vim /etc/cinder/cinder.conf

[database]
connection = mysql+pymysql://cinder:123@controller/cinder

[DEFAULT]
transport_url = rabbit://openstack:123@controller
auth_strategy = keystone
my_ip = 192.168.144.20

[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = 123

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

5、同步数据库

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

# mysql -ucinder -p123

MariaDB [(none)]> show databases;
MariaDB [(none)]> use cinder
MariaDB [cinder]> show tables;

6、配置nova服务以使用块存储

# vim /etc/nova/nova.conf

[cinder]
os_region_name = RegionOne

7、启动服务

# systemctl restart openstack-nova-api.service

# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

二、compute节点

1、安装LVM软件

# yum install lvm2 device-mapper-persistent-data

在compute节点上可以查看到我们在基础配置的时候添加的一个5G硬盘

创建LVM

# pvcreate /dev/sdb
# vgcreate cinder-volumes /dev/sdb

# vim /etc/lvm/lvm.conf

注意，如果你操作系统使用的也是LVM的话，那么就需要将sda也写进入，

filter = [ "a/sda/", "a/sdb/", "r/.*/"]

2、安装cinder软件

# yum install openstack-cinder targetcli python3-keystone

这里注意，软件包有变化从python-keystone——》python3-keystone

# vim /etc/cinder/cinder.conf

[database]
connection = mysql+pymysql://cinder:123@controller/cinder

[DEFAULT]
transport_url = rabbit://openstack:123@controller
auth_strategy = keystone
my_ip = 192.168.144.21
enabled_backends = lvm
glance_api_servers = http://controller:9292

[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = 123

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
target_protocol = iscsi
target_helper = lioadm

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

3、启动服务

# systemctl enable openstack-cinder-volume.service target.service
# systemctl start openstack-cinder-volume.service target.service

三、验证：

查cinder的服务状态，都是up的，

# source admin-openrc 
# openstack volume service list

创建一个volume卷

# openstack volume create --size 1 test

查看状态

# openstack volume list
