fgo小窍门

容灾 (Disaster Recovery)，即容灾备份或灾备，是业务连续性系统的一个子集，用于保障 IT 系统在遭受自然灾害、人为操作失误或蓄意破坏后的数据还原和业务恢复。

Ceph RGW 多数据中心（multisite）功能旨在实现异地双活，提供了备份容灾的能力。并且具有多个数据中心供用户选择，存放资源。

主节点在对外提供服务时，用户数据在主节点落盘后即向用户回应“写成功”应答，然后实时记录数据变化的相关日志信息。备节点则实时比较主备数据差异，并及时将差异化数据拉回备节点。异步复制技术适用于远距离的容灾方案，对系统性能影响较小。

以往的容灾都是在单该或者多该ceph集群之间的，本次主要由于模拟 ceph 的 RGW 可以与其他所有的S3云供应商(https://docs.ceph.com/en/latest/radosgw/cloud-sync-module/)进行数据同步，从而实现Ceph的RGW对象存储的灾备。

内容

要求：

Ceph 集群
2 个 RGW 守护进程正在运行
S3 目标

我们将使用三个端点：

http://192.168.112.5:80

RGW 为我们现有的集群管理的端点

http://192.168.112.6:80

我们将创建一个新端点，它将依赖 RGW 将数据同步到另一个 S3 提供者

http://192.168.105.5:80

我们将用于推送/同步数据的 S3 目标

检查我们现有的存储池：

所有 rgw 都有一个区域和区域组，它可能是default.

您可以检查池的名称：

(docker-croit)@mycephcluster / $ ceph osd lspools1 device_health_metrics2 .rgw.root3 default.rgw.control4 default.rgw.log5 default.rgw.meta6 default.rgw.buckets.non-ec7 default.rgw.buckets.index8 default.rgw.buckets.data

或者直接检查区域或区域组：

(docker-croit)@mycephcluster / $ radosgw-admin zone get --rgw-zone=default{   "id": "303a00f5-f50d-43fd-afee-aa0503926952",   "name": "default",...}

(docker-croit)@mycephcluster / $ radosgw-admin zonegroup get --rgw-zonegroup=default{   "id": "881cf806-f6d2-47a0-b7dc-d65ee87f8ef4",   "name": "default",   "api_name": "default",   "is_master": "true",...   "zones": [      {           "id": "303a00f5-f50d-43fd-afee-aa0503926952",           "name": "default",

准备存储池：

我们的新区将需要一些池。我们将手动创建它们以确保没有问题（例如每个 osd 有太多 PG）阻止它们的创建。

(docker-croit)@mycephcluster / $ for pool in sync.rgw.meta sync.rgw.log sync.rgw.control sync.rgw.buckets.non-ec sync.rgw.buckets.index sync.rgw.buckets.data; do ceph osd pool create $pool 16 16 replicated; donepool 'sync.rgw.meta' createdpool 'sync.rgw.log' createdpool 'sync.rgw.control' createdpool 'sync.rgw.buckets.non-ec' createdpool 'sync.rgw.buckets.index' createdpool 'sync.rgw.buckets.data' created

创建新区域：

我们的新区域将命名为sync：

(docker-croit)@mycephcluster / $ radosgw-admin zone create --rgw-zonegroup=default --rgw-zone=sync --endpoints=http://192.168.112.6/ --tier-type=cloud{   "id": "7ead9532-0938-4698-9b4a-2d84d0d00869",   "name": "sync",   "domain_root": "sync.rgw.meta:root",   "control_pool": "sync.rgw.control",   "gc_pool": "sync.rgw.log:gc",   "lc_pool": "sync.rgw.log:lc",   "log_pool": "sync.rgw.log",   "intent_log_pool": "sync.rgw.log:intent",   "usage_log_pool": "sync.rgw.log:usage",   "roles_pool": "sync.rgw.meta:roles",   "reshard_pool": "sync.rgw.log:reshard",   "user_keys_pool": "sync.rgw.meta:users.keys",   "user_email_pool": "sync.rgw.meta:users.email",   "user_swift_pool": "sync.rgw.meta:users.swift",   "user_uid_pool": "sync.rgw.meta:users.uid",   "otp_pool": "sync.rgw.otp",   "system_key": {       "access_key": "",       "secret_key": ""  },   "placement_pools": [      {           "key": "default-placement",           "val": {               "index_pool": "sync.rgw.buckets.index",               "storage_classes": {                   "STANDARD": {                       "data_pool": "sync.rgw.buckets.data"                  }              },               "data_extra_pool": "sync.rgw.buckets.non-ec",               "index_type": 0          }      }  ],   "realm_id": "46669d35-f7ed-4374-8247-2b8f41218109"}

rgw-zonegroup：我们的新区域将成为默认区域组的一部分。
端点：我们的新区域需要它自己的 RGW，因此它使用新的端点。
tier-type ：我们使用cloud层类型，请参阅文档(https://docs.ceph.com/en/latest/radosgw/cloud-sync-module/)了解更多设置

修改现有区域：

我们需要添加现有default区域的端点。

(docker-croit)@mycephcluster / $ radosgw-admin zone modify --rgw-zonegroup=default --rgw-zone=default --endpoints=http://192.168.112.5:80{   "id": "303a00f5-f50d-43fd-afee-aa0503926952",   "name": "default",   "domain_root": "default.rgw.meta:root",   "control_pool": "default.rgw.control",   "gc_pool": "default.rgw.log:gc",   "lc_pool": "default.rgw.log:lc",   "log_pool": "default.rgw.log",   "intent_log_pool": "default.rgw.log:intent",   "usage_log_pool": "default.rgw.log:usage",   "roles_pool": "default.rgw.meta:roles",   "reshard_pool": "default.rgw.log:reshard",   "user_keys_pool": "default.rgw.meta:users.keys",   "user_email_pool": "default.rgw.meta:users.email",   "user_swift_pool": "default.rgw.meta:users.swift",   "user_uid_pool": "default.rgw.meta:users.uid",   "otp_pool": "default.rgw.otp",   "system_key": {       "access_key": "",       "secret_key": ""  },   "placement_pools": [      {           "key": "default-placement",           "val": {               "index_pool": "default.rgw.buckets.index",               "storage_classes": {                   "STANDARD": {                       "data_pool": "default.rgw.buckets.data"                  }              },               "data_extra_pool": "default.rgw.buckets.non-ec",               "index_type": 0          }      }  ],   "realm_id": "46669d35-f7ed-4374-8247-2b8f41218109"}

创建系统用户：

系统用户将用于同步数据，可以通过 CLI 创建此用户。

(docker-croit)@mycephcluster / $ radosgw-admin user create --uid=syncuser --display-name=syncuser --system{   "user_id": "syncuser",   "display_name": "syncuser",   "email": "",   "suspended": 0,   "max_buckets": 1000,   "subusers": [],   "keys": [      {           "user": "syncuser",           "access_key": "VGIF31FGOHZ0Q6MQRBQR",           "secret_key": "1FwPZH0ICfV1e1zi8okXApJJJEB0XHfiOxe1mmTr"      }  ],   "swift_keys": [],   "caps": [],   "op_mask": "read, write, delete",   "system": "true",   "default_placement": "",   "default_storage_class": "",   "placement_tags": [],   "bucket_quota": {       "enabled": false,       "check_on_raw": false,       "max_size": -1,       "max_size_kb": 0,       "max_objects": -1  },   "user_quota": {       "enabled": false,       "check_on_raw": false,       "max_size": -1,       "max_size_kb": 0,       "max_objects": -1  },   "temp_url_keys": [],   "type": "rgw",   "mfa_ids": []}

配置同步区域以使用此系统用户：

我们将更改两个区域以使用我们的新系统用户。

(docker-croit)@mycephcluster / $ radosgw-admin user info --uid syncuser| jq '.keys'[{   "user": "syncuser",   "access_key": "VGIF31FGOHZ0Q6MQRBQR",   "secret_key": "1FwPZH0ICfV1e1zi8okXApJJJEB0XHfiOxe1mmTr"}]

(docker-croit)@mycephcluster / $ radosgw-admin zone modify --rgw-zonegroup=default --rgw-zone=default --access-key=VGIF31FGOHZ0Q6MQRBQR --secret=1FwPZH0ICfV1e1zi8okXApJJJEB0XHfiOxe1mmTr{    "id": "303a00f5-f50d-43fd-afee-aa0503926952",    "name": "default",    "domain_root": "default.rgw.meta:root",    "control_pool": "default.rgw.control",    "gc_pool": "default.rgw.log:gc",    "lc_pool": "default.rgw.log:lc",    "log_pool": "default.rgw.log",    "intent_log_pool": "default.rgw.log:intent",    "usage_log_pool": "default.rgw.log:usage",    "roles_pool": "default.rgw.meta:roles",    "reshard_pool": "default.rgw.log:reshard",    "user_keys_pool": "default.rgw.meta:users.keys",    "user_email_pool": "default.rgw.meta:users.email",    "user_swift_pool": "default.rgw.meta:users.swift",    "user_uid_pool": "default.rgw.meta:users.uid",    "otp_pool": "default.rgw.otp",    "system_key": {        "access_key": "VGIF31FGOHZ0Q6MQRBQR",        "secret_key": "1FwPZH0ICfV1e1zi8okXApJJJEB0XHfiOxe1mmTr"    },    "placement_pools": [        {            "key": "default-placement",            "val": {                "index_pool": "default.rgw.buckets.index",                "storage_classes": {                    "STANDARD": {                        "data_pool": "default.rgw.buckets.data"                    }                },                "data_extra_pool": "default.rgw.buckets.non-ec",                "index_type": 0            }        }    ],    "realm_id": "46669d35-f7ed-4374-8247-2b8f41218109"}

(docker-croit)@mycephcluster / $ radosgw-admin zone modify --rgw-zonegroup=default --rgw-zone=sync --access-key=VGIF31FGOHZ0Q6MQRBQR --secret=1FwPZH0ICfV1e1zi8okXApJJJEB0XHfiOxe1mmTr{    "id": "7ead9532-0938-4698-9b4a-2d84d0d00869",    "name": "sync",    "domain_root": "sync.rgw.meta:root",    "control_pool": "sync.rgw.control",    "gc_pool": "sync.rgw.log:gc",    "lc_pool": "sync.rgw.log:lc",    "log_pool": "sync.rgw.log",    "intent_log_pool": "sync.rgw.log:intent",    "usage_log_pool": "sync.rgw.log:usage",    "roles_pool": "sync.rgw.meta:roles",    "reshard_pool": "sync.rgw.log:reshard",    "user_keys_pool": "sync.rgw.meta:users.keys",    "user_email_pool": "sync.rgw.meta:users.email",    "user_swift_pool": "sync.rgw.meta:users.swift",    "user_uid_pool": "sync.rgw.meta:users.uid",    "otp_pool": "sync.rgw.otp",    "system_key": {        "access_key": "VGIF31FGOHZ0Q6MQRBQR",        "secret_key": "1FwPZH0ICfV1e1zi8okXApJJJEB0XHfiOxe1mmTr"    },    "placement_pools": [        {            "key": "default-placement",            "val": {                "index_pool": "sync.rgw.buckets.index",                "storage_classes": {                    "STANDARD": {                        "data_pool": "sync.rgw.buckets.data"                    }                },                "data_extra_pool": "sync.rgw.buckets.non-ec",                "index_type": 0            }        }    ],    "tier_config": {        "connection": {            "access_key": "JO4RQ1787A6OGI6XMFDW",            "endpoint": "http://192.168.105.5:80",            "secret": "Dx5kKGUUeR0DaSRYueBWhV6oDRvJ9oXH2gPcVJ6s"        }    },    "realm_id": "46669d35-f7ed-4374-8247-2b8f41218109"}

确保默认区域是主区域：

(docker-croit)@mycephcluster / $ radosgw-admin zonegroup get{    "id": "881cf806-f6d2-47a0-b7dc-d65ee87f8ef4",    "name": "default",    "api_name": "default",    "is_master": "true",    "endpoints": [],    "hostnames": [],    "hostnames_s3website": [],    "master_zone": "303a00f5-f50d-43fd-afee-aa0503926952",    "zones": [        {            "id": "303a00f5-f50d-43fd-afee-aa0503926952",            "name": "default",

如果defaultzone 不是 master，则可以通过执行强制它radosgw-admin zone modify --rgw-zonegroup=default --rgw-zone=default --master --default

提交更改并验证配置：

(docker-croit)@mycephcluster / $ radosgw-admin period update --commit{    "id": "1861622f-b748-410d-b4a9-7338f4b6842b",    "epoch": 3,    "predecessor_uuid": "b6cd42db-6567-4a4b-9433-aee238da0c9d",    "sync_status": [],    "period_map": {        "id": "1861622f-b748-410d-b4a9-7338f4b6842b",        "zonegroups": [            {                "id": "881cf806-f6d2-47a0-b7dc-d65ee87f8ef4",                "name": "default",                "api_name": "default",                "is_master": "true",                "endpoints": [],                "hostnames": [],                "hostnames_s3website": [],                "master_zone": "303a00f5-f50d-43fd-afee-aa0503926952",                "zones": [                    {                        "id": "303a00f5-f50d-43fd-afee-aa0503926952",                        "name": "default",                        "endpoints": [                            "http://192.168.112.5:80"                        ],                        "log_meta": "false",                        "log_data": "true",                        "bucket_index_max_shards": 11,                        "read_only": "false",                        "tier_type": "",                        "sync_from_all": "true",                        "sync_from": [],                        "redirect_zone": ""                    },                    {                        "id": "7ead9532-0938-4698-9b4a-2d84d0d00869",                        "name": "sync",                        "endpoints": [                            "http://192.168.112.6/"                        ],                        "log_meta": "false",                        "log_data": "true",                        "bucket_index_max_shards": 11,                        "read_only": "false",                        "tier_type": "cloud",                        "sync_from_all": "true",                        "sync_from": [],                        "redirect_zone": ""                    }                ],                "placement_targets": [                    {                        "name": "default-placement",                        "tags": [],                        "storage_classes": [                            "STANDARD"                        ]                    }                ],                "default_placement": "default-placement",                "realm_id": "46669d35-f7ed-4374-8247-2b8f41218109",                "sync_policy": {                    "groups": []                }            }        ],        "short_zone_ids": [            {                "key": "303a00f5-f50d-43fd-afee-aa0503926952",                "val": 2796720163            },            {                "key": "7ead9532-0938-4698-9b4a-2d84d0d00869",                "val": 2175446857            }        ]    },    "master_zonegroup": "881cf806-f6d2-47a0-b7dc-d65ee87f8ef4",    "master_zone": "303a00f5-f50d-43fd-afee-aa0503926952",    "period_config": {        "bucket_quota": {            "enabled": false,            "check_on_raw": false,            "max_size": -1,            "max_size_kb": 0,            "max_objects": -1        },        "user_quota": {            "enabled": false,            "check_on_raw": false,            "max_size": -1,            "max_size_kb": 0,            "max_objects": -1        }    },    "realm_id": "46669d35-f7ed-4374-8247-2b8f41218109",    "realm_name": "default",    "realm_epoch": 2}

配置新区域：

我们的云同步模块需要一些配置(https://docs.ceph.com/en/latest/radosgw/cloud-sync-module/#cloud-sync-tier-type-configuration)。

我们将定义用于同步数据的端点和 S3 用户凭据。注意：如果您的密钥以 0 开头，您将无法配置它。例如，使用05XXXXXXXX时，访问密钥将被错误地存储：

配置 RGW：

我们需要修改每个 radosgw 配置以通过删除rgw zone = default和添加来管理正确的区域

[client.rgw.$(hostname)]host = $(hostname)rgw zone = default[client.rgw.$(hostname)]host = $(hostname)rgw zone = sync

在我们的基础设施上，我们/etc/ceph/ceph.conf通过添加以下内容进行编辑：

[client.rgw.new-croit-host-C0DE01]host = new-croit-host-C0DE01rgw zone = default[client.rgw.new-croit-host-C0DE02]host = new-croit-host-C0DE02rgw zone = sync

如果你使用 croit，你可以简单地ceph.conf用这个内容替换模板。

[global]auth cluster required = cephxauth service required = cephxauth client required = cephxauth supported = cephxmon client hunt interval = {{huntInterval}}mon client hunt parallel = {{huntParallel}}fsid = {{fsid}}mon host = {{commaSeparatedList mons}}{{~#if full}}{{~#unless server.managementHost}}crush location = host={{server.hostname}}{{~/unless}}{{~#if publicNets}}public network = {
}{{~/if}}{{~#if privateNets}}cluster network = {
}{{~/if}}log file = /dev/nullmon cluster log file = /dev/nullmon cluster log to syslog = truelog to syslog = trueerr to syslog = true{{~#replaceAll "rgw zone = default" ""~}}{{~#options}}{{key}} = {{value}}{{~/options}}{{~/replaceAll}}[client.rgw.new-croit-host-C0DE01]host = new-croit-host-C0DE01rgw zone = default[client.rgw.new-croit-host-C0DE02]host = new-croit-host-C0DE02rgw zone = sync{{~/if}}

要应用更改，您必须重新启动 RGW。

root@new-croit-host-C0DE01 ~ $ systemctl restart ceph-radosgw@rgw.new-croit-host-C0DE01.serviceroot@new-croit-host-C0DE02 ~ $ systemctl restart ceph-radosgw@rgw.new-croit-host-C0DE02.service

测试 S3 同步

我们将使用 s3cmd 进行测试。

在源和目标上生成用户并配置他们的 s3cmd 配置文件。检查 API 访问是否有效。

~ s3cmd -c .s3cfg_source ls~ s3cmd -c .s3cfg_target ls~

如果您有 API 错误错误，请检查您的凭据、端点。

在源上创建一个存储桶并添加对象：

我们首先创建一个bucket：

~ s3cmd -c .s3cfg_source mb s3://mystetbucketBucket 's3://mystetbucket/' created~ s3cmd -c .s3cfg_source ls2021-06-24 15:06  s3://mystetbucket

现在我们在源上添加一个对象：

~ s3cmd -c .s3cfg_source put /tmp/myobject s3://mystetbucket/synctest                                                                                                                                                                                 64WARNING: Module python-magic is not available. Guessing MIME types based on file extensions.upload: '/tmp/myobject' -> 's3://mystetbucket/synctest'  [1 of 1] 13 of 13   100% in    0s   325.90 B/s  done

并检查它是否已同步到目标：

~ s3cmd -c .s3cfg_target ls s3://2021-06-24 15:30  s3://rgw-default-271b93c16a9565d8~ s3cmd -c .s3cfg_target ls s3://rgw-default-271b93c16a9565d8                          DIR  s3://rgw-default-271b93c16a9565d8/mystetbucket/~ s3cmd -c .s3cfg_target ls s3://rgw-default-271b93c16a9565d8/mystetbucket/2021-06-24 15:36           13  s3://rgw-default-271b93c16a9565d8/mystetbucket/synctest

技巧和窍门

您可以随时增加调试日志记录以便于调试：

root@new-croit-host-C0DE02 ~ $ ceph --admin-daemon /var/run/ceph/ceph-client.rgw.new-croit-host-C0DE02.96866.94534872347832.asok config set debug_rgw_sync 5root@new-croit-host-C0DE02 ~ $ ceph --admin-daemon /var/run/ceph/ceph-client.rgw.new-croit-host-C0DE02.96866.94534872347832.asok config set debug_rgw 5

检查同步状态：

(docker-croit)@mycephcluster / $ radosgw-admin sync status --rgw-zone=sync          realm 46669d35-f7ed-4374-8247-2b8f41218109 (default)      zonegroup 881cf806-f6d2-47a0-b7dc-d65ee87f8ef4 (default)           zone 7ead9532-0938-4698-9b4a-2d84d0d00869 (sync)  metadata sync syncing                full sync: 0/64 shards                incremental sync: 64/64 shards                metadata is caught up with master      data sync source: 303a00f5-f50d-43fd-afee-aa0503926952 (default)                        syncing                        full sync: 0/128 shards                        incremental sync: 128/128 shards                        data is caught up with source
