ceph & openstack cinder集成方案验证

一、ceph & openstack可集成部分

cinder

glance

nova

二、ceph&openstack cinder集成

功能支持：

ceph rbd作为cinder存储后端，完整的实现了cinder的接口

集成步骤：

在ceph中创建池供openstack使用

ceph osd pool create dk-pool 2048 2048

ceph中创建相关的账号，并设置权限,dk-cinder 用于访问dk-pool

ceph auth get-or-create client.dk-cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=dk-pool'

同步ceph配置到openstack节点中(openstack将使用此配置访问ceph集群)

ssh {your-openstack-server} sudo tee /etc/ceph/ceph.conf </etc/ceph/ceph.conf

openstack主机安装相关的软件包

sudo apt-get install python-rbd
sudo apt-get install ceph-common

同步keyring文件

# 将dk-cinder user的keyring拷贝到cinder volume节点,并更改相应的权限.
ceph auth get-or-create client.dk-cinder | ssh {your-openstack-server}  sudo tee /etc/ceph/ceph.client.dk-cinder.keyring
ssh {your-openstack-server}  sudo chown cinder:cinder /etc/ceph/ceph.client.dk-cinder.keyring (devstack环境中不需要设置用户组)

nova认证dk-cinder

ceph auth get-key client.dk-cinder | ssh {your-compute-node} sudo tee /etc/ceph/client.dk-cinder.key

uuidgen
>   70cafbfb-3f5e-48c5-8acc-32858cb0814d

cat > secret.xml <<EOF
<secret ephemeral='no' private='no'>
<uuid> 70cafbfb-3f5e-48c5-8acc-32858cb0814d</uuid>
<usage type='ceph'>
<name>client.dk-cinder secret</name>
</usage>
</secret>
EOF

sudo virsh secret-define --file secret.xml
sudo virsh secret-set-value --secret  70cafbfb-3f5e-48c5-8acc-32858cb0814d --base64 $(cat client.dk-cinder.key) && rm client.dk-cinder.key secret.xml

- 设置cinder.conf（/etc/cinder/cinder.conf）

backend name （rbd2）可随意设置，保持统一就行

cat cinder.conf
[DEFAULT]
...
enabled_backends = rbd2
...
[rbd2]
volume_driver = cinder.volume.drivers.rbd.RBDDriver
rados_connect_timeout = -1
rados_connection_interval = 5
rados_connection_retries = 3
rdb_ceph_conf = /etc/ceph/ceph.conf
rbd_cluster_name = ceph
rbd_flatten_volume_from_snapshot = True
rbd_max_clone_depth = 5
rbd_pool = dk-pool
rbd_user = dk-cinder
rbd_secret_uuid = 70cafbfb-3f5e-48c5-8acc-32858cb0814d
rbd_store_chunk_size = 4
volume_backend_name = rbd2

重启cinder服务，查看cinder list

集成验证:

创建卷类型



设置volume type



创建卷





查看卷信息



ceph ls dk-pool

openstack平台环境搭建

部署步骤:

Add Stack User

$ sudo useradd -s /bin/bash -d /opt/stack -m stack
$ echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
$ sudo su - stack

Download DevStack

$ git clone https://git.openstack.org/openstack-dev/devstack $ cd devstack

Create a local.conf

[[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

Start the install

./stack.sh

依赖问题:

依赖及Python库版本问题，根据错误信息修改替换即可

etcd-v3.1.10-linux-amd64.tar.gz 无法自动下载成功，手动从错误处的网址下载，放在/opt/stack/devstack/files 目录中

（如果提示MD5校验失败，手动删除md5记录文件）

mysql安装失败: purse autoremove autoclean 后重新安装

配置源：

vi ~/.pip/pip.conf
[global]
index-url=http://mirrors.aliyun.com/pypi/simple/

[install]

trusted-host=mirrors.aliyun.com

vi /etc/apt/sources.lis
