OpenStack之Queen版本安装cinder服务

cinder节点配置安装

该服务使用LVM驱动程序在该设备上配置逻辑卷，并通过iSCSI传输将其提供给实例。 您可以按照这些说明进行小的修改，以便使用其他存储节点水平扩展您的环境。

1.安装支持的软件包

安装LVM，

yum install lvm2 device-mapper-persistent-data

编辑/etc/lvm/lvm.conf

devices {
filter = [ "a/sda/", "a/sdb/", "r/.*/"]   //devices大括号中  添加这行

设置LVM服务开机启动

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

2.创建LVM物理逻辑卷/dev/sdb

先给cinder节点加第二块硬盘，我设置的大小是30G。
然后对硬盘进行格式化以及分配。
可参考

fdisk /dev/vdb  //分区
partprobe    //刷新到内核

分区完成后再执行pvcreate和vgcreate。

[root@cinder ~]# pvcreate /dev/sdb1
Device /dev/sdb not found (or ignored by filtering).

解决方案：

编辑 vim /etc/lvm/lvm.conf,找到global_filter一行，配置如下

   global_filter = [ "a|.*/|","a|sdb1|"]

之后再执行pvcreate命令，问题解决。

[root@cinder ~]# pvcreate /dev/sdb1
Physical volume "/dev/sdb1" successfully created.

3.创建cinder-volumes逻辑卷组

[root@cinder ~]# vgcreate cinder-volumes /dev/sdb1
Volume group "cinder-volumes" successfully created

4.安装和配置组件

安装软件包

yum install openstack-cinder targetcli python-keystone -y

编辑/etc/cinder/cinder.conf

[DEFAULT]

transport_url = rabbit://openstack:123456@controller
auth_strategy = keystone
my_ip = 172.17.168.130
enabled_backends = lvm
glance_api_servers = http://controller:9292

[database]

connection = mysql+pymysql://cinder:123456@controller/cinder

[keystone_authtoken]

auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = 123456

在[lvm]部分中，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。 如果[lvm]部分不存在，请创建它：

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

[oslo_concurrency]

lock_path = /var/lib/cinder/tmp

设置存储服务开机启动

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

控制节点

1. 创建cinder数据库

# 在任意控制节点创建数据库，后台数据自动同步，以controller01节点为例；
[root@controller01 ~]# mysql -uroot -pmysql_pass

MariaDB [(none)]> CREATE DATABASE cinder;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY '123456';

MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit;

2. 创建cinder-api

# 在任意控制节点操作，以controller01节点为例；
# 调用cinder服务需要认证信息，加载环境变量脚本即可
[root@controller ~]# . admin-openrc

1）创建cinder用户

# service项目已在glance章节创建；
# neutron用户在”default” domain中
[root@controller ~]# openstack user create --domain default --password=cinder_pass cinder

2）cinder赋权

# 为cinder用户赋予admin权限
[root@controller ~]# openstack role add --project service --user cinder admin

3）创建cinder服务实体

# cinder服务实体类型”volume”；
# 创建v2/v3两个服务实体
[root@controller ~]# openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
[root@controller ~]# openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3

4）创建cinder-api

# 注意--region与初始化admin用户时生成的region一致；
# api地址统一采用vip，如果public/internal/admin分别使用不同的vip，请注意区分；
# cinder-api 服务类型为volume；
# cinder-api后缀为用户project-id，可通过”openstack project list”查看
# v2 public api
[root@controller ~]# openstack endpoint create --region RegionTest volumev2 public http://controller:8776/v2/%(project_id)s


# v2 internal api
[root@controller ~]# openstack endpoint create --region RegionTest volumev2 internal http://controller:8776/v2/%(project_id)s


# v2 admin api
[root@controller ~]# openstack endpoint create --region RegionTest volumev2 admin http://controller:8776/v2/%(project_id)s


# v3 public api
[root@controller ~]# openstack endpoint create --region RegionTest volumev3 public http://controller:8776/v3/%(project_id)s


# v3 internal api
[root@controller ~]# openstack endpoint create --region RegionTest volumev3 internal http://controller:8776/v3/%(project_id)s


# v3 admin api
[root@controller ~]# openstack endpoint create --region RegionTest volumev3 admin http://controller:8776/v3/%(project_id)s

3. 安装cinder

# 在全部控制节点安装cinder服务，以controller01节点为例
[root@controller ~]# yum install openstack-cinder -y

4. 配置cinder.conf

[DEFAULT]
rpc_backend = rabbit
enabled_backends = lvm
auth_strategy = keystone
report_interval = 10
[backend]
[backend_defaults]
[barbican]
[brcd_fabric_example]
[cisco_fabric_example]
[coordination]
[cors]
[database]
connection = mysql+pymysql://cinder:123456@controller/cinder
[fc-zone-manager]
[healthcheck]
[key_manager]
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = 123456
[nova]
[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
[oslo_messaging_amqp]
[oslo_messaging_kafka]
[oslo_messaging_notifications]
[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = 123456
[oslo_middleware]
[oslo_policy]
[oslo_reports]
[oslo_versionedobjects]
[privsep]
[profiler]
[sample_castellan_source]
[sample_remote_file_source]
[service_user]
[ssl]
[vault]
[lvm]
volume_group = centos

5. 配置nova.conf

# 在全部控制节点操作，以controller01节点为例；
# 配置只涉及nova.conf的”[cinder]”字段；
# 加入对应regiong
[root@controller ~]# vim /etc/nova/nova.conf
[cinder]
os_region_name=RegionTest

6. 同步cinder数据库

# 任意控制节点操作；
# 忽略部分”deprecation”信息
[root@controller ~]# su -s /bin/sh -c "cinder-manage db sync" cinder

## 验证
[root@controller ~]# mysql -h controller -ucinder -p123456 -e "use cinder;show tables;"

7. 启动服务

# 全部控制节点操作；
# 变更nova配置文件，首先需要重启nova服务
[root@controller ~]# systemctl restart openstack-nova-api.service


### 开机启动

[root@controller ~]# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service

### 启动

[root@controller ~]# systemctl restart openstack-cinder-api.service
[root@controller ~]# systemctl restart openstack-cinder-scheduler.service

8. 验证

[root@controller ~]# . admin-openrc

查看agent服务；

[root@controller ~]# openstack volume service list   # 或：cinder service-list
