012 Ceph多区域网关
一、基本概念
1.1 多区域概念
Multi-Size功能是从J版本开始的。一个single zone配置通常由一个zone group组成，该zone group包含一个zone和多个用于负载均衡的RGW实例。从K版本开始，ceph为RGW提供了Multi-Size的配置选项
1.2 多区域相关术语
区域（zone）: 一个ceph集群可以包含多个区域，一个区域只属于一个集群，一个区域可以有多个RGW
区域组（zonegroup）：由一个或多个区域组成，包含一个主区域（master zone），其他区域称为Secondary Zone，区域组内的所有区域之间同步数据
域（realm）: 同一个或多个区域组组成，包含一个主区域组，其他都次区域组。域中的所有rados网关都从位于主区域组和主区域中的rados网关拉取配置
注意： master zone group中的master zone处理所元数据更新，因此创建用户、bucket等操作都必须经由master zone
1.3 多区域网关配置架构
single-zone：一个realm中只有一个zonegroup和一个zone，可以有多个RGW
multi-zone：一个relam中只有一个zonegroup，但是有多个zone。一个realm中存储的数据复制到该zonegroup中的所有zone中
multi-zonegroup：一个realm中有多个zonegroup，每个zonegroup中又有一个或多个zone
multi-realms：多个realm
两个集群配置两个zone，实现两个zone之间的数据同步：
periods和Epochs：
每个zone有关联的period，每个period有关联的epoch。
period用于跟踪zone、zone group和realm的配置状态
epoch用于跟踪zone period的配置变更的版本号
每个period具有唯一ID，含有zone配置，并且知道其先前period的id
在更改zone的配置时，需要更新zone的当前period
1.4 多区域同步流程
RGW在所有zone group集合之间同步元数据和数据操作。元数据操作与bucket相关：创建、删除、启用和禁用版本控制、管理用户。meta master位于master zone group中的master zone，负责管理元数据更新
多区域配置后处于活跃状态时，RGW会在master和secondary区域之间执行一次初始的完整同步。随后的更新是增量更新
当RGW将数据写入zone group的任意zone时，它会在该zone group的所有其他zone之间同步这一数据
当RGW同步数据时，所有活跃的网关会更新数据日志并通知其他网关
当RGW网关因用户操作而同步元数据时，主网关会更新元数据日志并通知其他RGW网关
两个集群配置两个zone，实现两个zone之间的数据同步：periods和Epochs：每个zone有关联的period，每个period有关联的epoch。period用于跟踪zone、zone group和realm的配置状态epoch用于跟踪zone period的配置变更的版本号每个period具有唯一ID，含有zone配置，并且知道其先前period的id在更改zone的配置时，需要更新zone的
当前period多区域同步流程：RGW在所有zone group集合之间同步元数据和数据操作。元数据操作与bucket相关：创建、删除、启用和禁用版本控制、管理用户。meta master位于master zone group中的master zone，负责管理元数据更新多区域配置后处于活跃状态时，RGW会在master和secondary区域之间执行一次初始的完整同步。随后
的更新是增量更新当RGW将数据写入zone group的任意zone时，它会在该zone group的所有其他zone之间同步这一数据当RGW同步数据时，所有活跃的网关会更新数据日志并通知其他网关当RGW网关因用户操作而同步元数据时，主网关会更新元数据日志并通知其他RGW网关
二、配置
