八、OpenStack—Cinder组件安装

一、安装和配置控制器节点

1、先决条件

1）创建数据库
# mysql -u root -p
2）创建cinder数据库

MariaDB [(none)]> CREATE DATABASE cinder;

3）授予对cinder数据库的适当访问权限

MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CINDER_DBPASS';

4）退出数据库访问客户端

2、申明环境变量
# source openrc
3、创建cinder用户
# openstack user create --domain default --password=cinder cinder
4、将cinder用户添加到admin角色
# openstack role add --project service --user cinder admin
5、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

6、创建Block Storage服务API端点

# openstack endpoint create --region RegionOne volumev2 public http://node1:8776/v2/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev2 internal http://node1:8776/v2/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev2 admin http://node1:8776/v2/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev3 public http://node1:8776/v3/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev3 internal http://node1:8776/v3/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev3 admin http://node1:8776/v3/%\(project_id\)s

二、安装和配置

1、下载安装包
# yum install openstack-cinder
2、编辑配置文件
# vim /etc/cinder/cinder.conf

[DEFAULT]
my_ip = 172.16.254.63#本机管理网ip
glance_api_servers = http://node1:9292
auth_strategy = keystone
enabled_backends = lvm
transport_url = rabbit://openstack:admin@node1

[backend]

[barbican]

[brcd_fabric_example]

[cisco_fabric_example]

[coordination]

[cors]

[cors.subdomain]

[database]
connection = mysql+pymysql://cinder:CINDER_DBPASS@node1/cinder

[fc-zone-manager]

[healthcheck]

[key_manager]

[keystone_authtoken]
auth_uri = http://node1:5000
auth_url = http://node1:35357
memcached_servers = node1:
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = cinder

[matchmaker_redis]

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

[oslo_messaging_amqp]

[oslo_messaging_kafka]

[oslo_messaging_notifications]

[oslo_messaging_rabbit]

[oslo_messaging_zmq]

[oslo_middleware]

[oslo_policy]

[oslo_reports]

[oslo_versionedobjects]

[profiler]

[ssl]

[lvm]
#volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
#volume_group = cinder-vg
#volumes_dir = $state_path/volumes
#iscsi_protocol = iscsi
#iscsi_helper = lioadm
#iscsi_ip_address = 172.16.254.63

3、同步数据库

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

三、配置计算以使用存储

1、编辑/etc/nova/nova.conf文件
# vim /etc/nova/nova.conf

[cinder]
os_region_name = RegionOne

四、完成安装

1、重新启动Compute API服务

# systemctl restart openstack-nova-api.service

2、启动Block Storage服务并将其设置开机自启

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

至此控制节点配置完成，接下来存储节点配置

在配置存储节点之前请准备第二块磁盘

一、安装和配置存储节点

1、安装LVM包
# yum install lvm2
2、启动LVM元数据服务并设置开机自启

# systemctl enable lvm2-lvmetad.service
# systemctl start lvm2-lvmetad.service

3、创建LVM物理卷/dev/sdb

# pvcreate /dev/sdb
4、创建LVM卷组cinder-volumes
# vgcreate cinder-volumes /dev/sdb
5、编辑 /etc/lvm/lvm.conf，在该devices部分中，添加一个接受/dev/sdb设备的过滤 器并拒绝所有其他设备

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

二、安装和配置组件

1、下载安装包
# yum install openstack-cinder targetcli python-keystone
2、编辑/etc/cinder/cinder.conf
# vim /etc/cinder/cinder.conf

[DEFAULT]
my_ip = 172.16.254.63#存储节点ip
glance_api_servers = http://node1:9292
auth_strategy = keystone
enabled_backends = lvm
transport_url = rabbit://openstack:admin@node1

[backend]

[barbican]

[brcd_fabric_example]

[cisco_fabric_example]

[coordination]

[cors]

[cors.subdomain]

[database]
connection = mysql+pymysql://cinder:CINDER_DBPASS@node1/cinder

[fc-zone-manager]

[healthcheck]

[key_manager]

[keystone_authtoken]
auth_uri = http://node1:5000
auth_url = http://node1:35357
memcached_servers = node1:
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = cinder

[matchmaker_redis]

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

[oslo_messaging_amqp]

[oslo_messaging_kafka]

[oslo_messaging_notifications]

[oslo_messaging_rabbit]

[oslo_messaging_zmq]

[oslo_middleware]

[oslo_policy]

[oslo_reports]

[oslo_versionedobjects]

[profiler]

[ssl]

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
volumes_dir = $state_path/volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm
iscsi_ip_address = 172.16.254.63#存储节点ip

3、完成安装

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

三、验证

1、控制节点验证
# openstack volume service list

+------------------+------------+------+---------+-------+----------------------------+
| Binary           | Host       | Zone | Status  | State | Updated_at                 |
+------------------+------------+------+---------+-------+----------------------------+
| cinder-scheduler | controller | nova | enabled | up    | --30T02::41.000000 |
| cinder-volume    | block@lvm  | nova | enabled | up    | --30T02::46.000000 |
+------------------+------------+------+---------+-------+----------------------------+

2、至此openstack需要组件全部搭完，可以到web界面创造实例检查是否搭建成功

3、检查opensatck服务是否正常常用命令

 # opensatck network agent list
 # opensatck compute service list
 # opnsatck volume service list
