容灾 (Disaster Recovery)，即容灾备份或灾备，是业务联贯性系统的一个子集，用于保险 IT 系统在遭遇当然灾害、东说念主为操作造作或策画破裂后的数据还原和业务收复。
Ceph RGW 广博据中心(multisite)功能旨在完竣他乡双活，提供了备份容灾的才气。而况具有多个数据中心供用户采选，存放资源。
主节点在对外提供处事时，用户数据在主节点落盘后即向用户恢复“写顺利”搪塞，然后实时记载数据变化的相干日记信息。备节点则实时相比主备数据互异，并实时将互异化数据拉回备节点。异步复制技巧适用于远距离的容灾决策，对系统性能影响较小。
首先第一种，是白羊座的冲动型喜欢，就是白羊座这一刻这一秒觉得自己是喜欢你的，冲动和你在一起了，但在一起后热情和新鲜感逐渐消退，然后渐渐冷却，在这个情况下其实感情已经走到了尽头，无论是如何分手的，对于白羊座来说可能连痛都不会痛，直接拍拍屁股走人。这也就是我们常说的三分钟热度。
北京时间2023年5月6日1:34发生天蝎座14°58′半影月食（食甚在1:22）。非常有力的月食，是月门、日门加食相的打包。天蝎座满月是月历的贝尔丹，而就在这次月食之后一个小时，欧博官网网站我们迎来精确的贝尔丹日门——这个高度神圣的节日带着日月对齐的版本，将月食的能量放大十倍。（译注：贝尔丹是古代节日，代表夏季的到来，是春分与夏至之间的中点）。
以往的容灾齐是在单该莽撞多该ceph集群之间的，本次主要由于模拟 ceph 的 RGW 不错与其他系数的S3云供应商(https://docs.ceph.com/en/latest/radosgw/cloud-sync-module/)进行数据同步，从而完竣Ceph的RGW对象存储的灾备。
实质 条目： Ceph 集群 2 个 RGW 督察进度正在开动 S3 观念咱们将使用三个端点：
iba百家乐注册 http://192.168.112.5:80RGW 为咱们现存的集群处置的端点
http://192.168.112.6:80咱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咱们将用于推送/同步数据的 S3 观念
查抄咱们现存的存储池：
系数 rgw 齐有一个区域和区域组，它可能是default.
皇冠客服飞机：@seo3687您不错查抄池的称呼：
(docker-croit)@mycephcluster 北京赛车娱乐城/ $ ceph osd lspools 1 device_health_metrics 2 .rgw.root 3 default.rgw.control 4 default.rgw.log 5 default.rgw.meta 6 default.rgw.buckets.non-ec 7 default.rgw.buckets.index 8 default.rgw.buckets.data
莽撞平直查抄区域或区域组：
(docker-croit)@mycephcluster / $ radosgw-admin zone get --rgw-zone=default { "id": "303a00f5-f50d-43fd-afee-aa0503926952", "name": "default", ... }

皇冠体育hg86a
咱们的新区将需要一些池。咱们将手动创建它们以确保莫得问题(举例每个 osd 有太多 PG)拦阻它们的创建。
(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; done pool 'sync.rgw.meta' created pool 'sync.rgw.log' created pool 'sync.rgw.control' created pool 'sync.rgw.buckets.non-ec' created pool 'sync.rgw.buckets.index' created pool 'sync.rgw.buckets.data' created
创建新区域：
咱们的新区域将定名为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：咱们的新区域将成为默许区域组的一部分。
端点：咱们的新区域需要它我方的 RGW，因此它使用新的端点。
tier-type ：咱们使用cloud层类型，请参阅文档(https://docs.ceph.com/en/latest/radosgw/cloud-sync-module/)了解更多建树
修改现存区域：
咱们需要添加现存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，不错通过 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：
咱们将更变两个区域以使用咱们的新系统用户。

若是defaultzone 不是 master，则不错通过施行强制它radosgw-admin zone modify --rgw-zonegroup=default --rgw-zone=default --master --default
提交更变并考证配置：

咱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)。
咱们将界说用于同步数据的端点和 S3 用户凭证。堤防：若是您的密钥以 0 发轫，您将无法配置它。举例，使用05XXXXXXXX时 ，造访密钥将被罪过地存储：

配置 RGW：
咱们需要修改每个 radosgw 配置以通过删除rgw zone = default和添加来处置正确的区域
[client.rgw.$(hostname)] host = $(hostname) rgw zone = default [client.rgw.$(hostname)] host = $(hostname) rgw zone = sync
在咱们的基础活动上，咱们/etc/ceph/ceph.conf通过添加以下实质进行剪辑：
挑战[client.rgw.new-croit-host-C0DE01] host = new-croit-host-C0DE01 rgw zone = default [client.rgw.new-croit-host-C0DE02] host = new-croit-host-C0DE02 rgw zone = sync
若是你使用 croit，你不错浅陋地ceph.conf用这个实质替换模板。

要愚弄更变，您必须从头启动 RGW。

咱们将使用 s3cmd 进行测试。
