整个OpenStack是由控制节点,计算节点,网络节点,存储节点四大部分组成。上篇博文详细讲述了控制节点服务controller中的horizon组件,本篇博文将详解存储节点cinder的部署。分为两部分:控制节点和存储节点

OpenStack存储节点架构

存储节点包含Cinder,Swift等服务

主 机 系 统 IP地址 角 色
controller CentOS7 192.168.37.128 keystone、nova、glance、neutron、horizon、cinder、ntp、mariadb、rabbitmq、memcached、etcd、apache
compute CentOS7 192.168.37.130 nova、neutron、ntp
cinder CentOS7 192.168.37.131 cinder、ntp

实验过程

++安装和配置Cinder节点++
1、添加、新建一块磁盘sdb

fdisk /dev/sdb

2、创建LVM物理逻辑卷/dev/sdb1

pvcreate /dev/sdb1

3、创建cinder-volumes逻辑卷组

vgcreate cinder-volumes /dev/sdb1

4、yum安装cinder软件包

yum install openstack-cinder targetcli python-keystone -y

5、编辑配置文件
vim /etc/cinder/cinder.conf

[DEFAULT]
#1302
transport_url = rabbit://openstack:123456@controller
#399
auth_strategy = keystone
#291
my_ip = 192.168.175.155
#403
enabled_backends = lvm        #支持格式
#296
glance_api_servers = http://controller:9292

[database]
#3586
connection = mysql+pymysql://cinder:123456@controller/cinder

[keystone_authtoken]
#3850
auth_uri = http://controller:5000
auth_url = http://controller:35357
#3901
memcached_servers = controller:11211
#4008
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = 123456

[oslo_concurrency]
#4125
lock_path = /var/lib/cinder/tmp

#末尾添加[lvm] 模块,使用LVM驱动程序,cinder-volumes卷组,iSCSI协议和相应的iSCSI服务配置LVM后端。 
[lvm]              
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

6、开启cinder服务,设置开机自启动

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

++安装和配置controller节点++
1、配置数据库

mysql -u root -p
create database cinder;
grant all privileges on cinder. to 'cinder'@'localhost' identified by '123456';
grant all privileges on cinder.
to 'cinder'@'%' identified by '123456';

2、创建用户cinder

source ~/admin-openrc
openstack user create --domain default --password-prompt cinder
密码:123456

3、添加角色

openstack role add --project service --user cinder admin

4、创建cinderv2和cinderv3服务实体

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

5、创建块存储服务API

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

6、安装cinder软件包

yum install openstack-cinder -y

7、编辑配置文件
vim /etc/cinder/cinder.conf

[database]
#3586
connection = mysql+pymysql://cinder:123456@controller/cinder

[DEFAULT]
#1302
transport_url = rabbit://openstack:123456@controller
#399
auth_strategy = keystone
#291
my_ip = 192.168.175.145

[keystone_authtoken]
#3850
auth_uri = http://controller:5000
auth_url = http://controller:35357
#3901
memcached_servers = controller:11211
#4008
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = 123456

[oslo_concurrency]
#4126
lock_path = /var/lib/cinder/tmp

8、同步数据库

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

9、编辑nova配置文件
vim /etc/nova/nova.conf

[cinder]
#4237
os_region_name = RegionOne

10、重启openstack-nova-api服务,开启cinder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

11、查看用户cinder
