Swift文件存储对接Ceph RadosGW

实际上应该是 Ceph RadosGW 对接 OpenStack Keystone 身份认证,因为 RadosGW 提供了和 Swift 兼容的API,所有二者api是一样的,直接做个负载均衡到 RadosGW 就成了一个swift接口

#1. 前言

ceph.conf 配置中的键如果是空格形式的(形如“rgw keystone api version”),这种是 ceph octopus 版本最后一次出现,在 pacific 版本改为下划线形式。

重点:

如果使用 kolla-ansible 部署 RadosGW 兼容的 Swift ,不要去找那种 “手动部署RadosGW对接Swift” 的教程,因为kolla-ansible 已经为你准备好了 OpenStack 这边的一切配置。所有有关 OpenStack 这边的操作都 不要做!!!

RadosGW 兼容的 Swift:实际上没有部署 Swift,可以理解为把原本 Swift 的 api 重定向到了 RadosGW。而 RadosGW 有着和 Swift一样的api

#2. Ceph配置

RadosGW安装配置这里不再赘述,请参阅:

#2.1 检查Ceph.conf

做完之后你的ceph.conf应该大致如下:

建议取消所有缩进

[global]
auth_client_required = cephx
auth_cluster_required = cephx
auth_service_required = cephx
cluster_network = 10.10.11.1/24
fsid = 59063611-9b12-4807-bf9d-ecfa60480d94
mon_allow_pool_delete = true
mon_host = 10.10.1.51
ms_bind_ipv4 = true
ms_bind_ipv6 = false
osd_pool_default_min_size = 2
osd_pool_default_size = 2
public_network = 10.10.1.51/24

[client]
keyring = /etc/ceph/priv/$cluster.$name.keyring

[client.radosgw.pve1]
host = pve1
keyring = /etc/ceph/priv/ceph.client.radosgw.keyring

# common
rgw_keystone_url = 10.10.1.250:5000
rgw_keystone_api_version = 3
# rgw_keystone_verify_ssl = false
 
# v3
rgw_keystone_admin_domain = Default
rgw_keystone_admin_project = admin
rgw_keystone_admin_token = gAAAAABj4bqH7oqC7X45z41YGs

# other
# rgw_s3_auth_use_keystone = true
# rgw_swift_account_in_url = true


[mds]
keyring = /var/lib/ceph/mds/ceph-$id/keyring

[mds.pve1]
host = pve1
mds_standby_for_name = ceph

[mon.pve1]
public_addr = 10.10.1.51

#2.2 对接Keystone

这里需要先安装一个cli client工具。进入部署机,激活python虚拟环境,source admin授权文件,安装

. /path/to/venv/bin/activate
. /etc/kolla/admin-openrc.sh
pip install python-swiftclient

验证安装

swift --help

#2.3 获取Auth Token

swift auth
export OS_STORAGE_URL=http://10.10.1.250:6780/swift/v1
export OS_AUTH_TOKEN=gAAAAABj4cEubXFK1PLGUicIMKMft6TiWitNcGhzHJxS2CWbetUEYIHbCJMx3v_iLQ142ZgjQ9KvtwLwoDrP-_RctuP45O9FTVr1dAVWrEKZngXpxX2uRVSELz7FP27vmZqtN0

感兴趣的可以再试试下面两个命令:

swift auth -v

swift auth –debug

把 OS_AUTH_TOKEN 记录下来,回到 Ceph 部署主机

echo "gAAAAABj4cID5BqJhJcRPfAJniQ-eqt66praFVJ2ZwSGUMd6QgdUplNUJlih-AGOzYw5t5HOWHiCsTGsMfU2uJpBwbXsC_2Y8hpqSwqqICth8xfLtnivPcKaT__K9CNASb92REHMECmQI" >> /etc/ceph/keystone_admin_token

#2.4 配置RadosGW

在Ceph 部署主机节点中,打开ceph.conf,在[client.radosgw.pve1]节点下新增:

# common
rgw_keystone_url = 10.10.1.250:5000
rgw_keystone_api_version = 3
# rgw_keystone_verify_ssl = false

# v3
rgw_keystone_admin_domain = Default
rgw_keystone_admin_project = admin
rgw_keystone_admin_token = gAAAAABj4bqH7oqC7X45z41YGsrBR5U5RfMbHylk6nlk2ZquW58h0

# other
# rgw_s3_auth_use_keystone = true
# rgw_swift_account_in_url = true

完成后,整个ceph.conf看起来如下

[global]
auth_client_required = cephx
auth_cluster_required = cephx
auth_service_required = cephx
cluster_network = 10.10.11.1/24
fsid = 59063611-9b12-4807-bf9d-ecfa60480d94
mon_allow_pool_delete = true
mon_host = 10.10.1.51
ms_bind_ipv4 = true
ms_bind_ipv6 = false
osd_pool_default_min_size = 2
osd_pool_default_size = 2
public_network = 10.10.1.51/24

[client]
keyring = /etc/pve/priv/$cluster.$name.keyring

[client.radosgw.pve1]
host = pve1
keyring = /etc/pve/priv/ceph.client.radosgw.keyring

# common
rgw_keystone_url = 10.10.1.250:5000
rgw_keystone_api_version = 3
# rgw_keystone_verify_ssl = false

# v3
rgw_keystone_admin_domain = Default
rgw_keystone_admin_project = admin
rgw_keystone_admin_token = gAAAAABj4bqH7oqC7X45z41YGs

# other
# rgw_s3_auth_use_keystone = true
# rgw_swift_account_in_url = true

[mds]
keyring = /var/lib/ceph/mds/ceph-$id/keyring

[mds.pve1]
host = pve1
mds standby for name = pve

[mon.pve1]
public_addr = 10.10.1.51

上传保存,重启 RadosGW (容器方式)

#3. kolla配置

#3.1 启用 Ceph RadosGW 集成

在部署机,/etc/kolla/global.yml

enable_ceph_rgw: true

#3.2 添加rgw主机

在 enable_ceph_rgw: “yes” 下面一行,增加

ceph_rgw_hosts:
  - host: rgw01
    ip: 10.10.1.51
    port: 7480

host 是名字随意,不需要解析dns,但是一定要填写ip

端口7480,是 RadosGW 默认端口,可以在 RadosGW 文档中查询到 rgw_frontends 属性

#4. 重新部署

kolla-ansible -i ./multinode deploy

#5. 验证

#5.1 验证负载均衡

haproxy报告查看:

radosgw_back 都是绿色就行

#5.2 验证客户端

回到部署机,输入 swift stat

(venv) root@ttt:~# swift stat
                                    Account: v1

(venv) root@ttt:~# 

#5.3 验证 Horizon

重新登录Horizon,项目>对象存储>容器

随便创建一个

创建成功

上传文件,再下载,没问题
