一. 掌握对象存储的特点及使用场景
#RadosGW 存储特点
通过对象存储网关将数据存储为对象，每个对象除了包含数据，还包含数据自身的元数据。
对象通过 Object ID 来检索，无法通过普通文件系统的挂载方式通过文件路径加文件名称操作来直接访问对象，只能通过 API 来访问，或者第三方客户端（实际上也是对 API 的封装）。
对象的存储不是垂直的目录树结构，而是存储在扁平的命名空间中，Amazon S3 将这个扁平命名空间称为 bucket，而 swift 则将其称为容器。
无论是 bucket 还是容器，都不能再嵌套(在 bucket 不能再包含 bucket)。
bucket 需要被授权才能访问到，一个帐户可以对多个 bucket 授权，而权限可以不同。
方便横向扩展、快速检索数据。
不支持客户端挂载,且需要客户端在访问的时候指定文件名称。
不是很适用于文件过于频繁修改及删除的场景。
ceph 使用 bucket 作为存储桶(存储空间)，实现对象数据的存储和多用户隔离，数据存储在bucket 中，用户的权限也是针对 bucket 进行授权，可以设置用户对不同的 bucket 拥有不同的权限，以实现权限管理。
#bucket特性:
11. 存储空间(bucket)是用于存储对象（Object）的容器，所有的对象都必须隶属于某个存储空间，可以设置和修改存储空间属性用来控制地域、访问权限、生命周期等，这些属性设置直
接作用于该存储空间内所有对象，因此可以通过灵活创建不同的存储空间来完成不同的管理功能。
12. 同一个存储空间的内部是扁平的，没有文件系统的目录等概念，所有的对象都直接隶属于其对应的存储空间。
13. 每个用户可以拥有多个存储空间
14. 存储空间的名称在 OSS 范围内必须是全局唯一的，一旦创建之后无法修改名称。
15. 存储空间内部的对象数目没有限制。
#radosgw 架构图
二. 在两台主机部署 radowsgw 存储网关以实现高可用环境
#安装 radosgw服务并初始化
root@ceph-mgr1:~# apt install radosgw
root@ceph-mgr2:~# apt install radosgw
#在 ceph deploy 服务器将 ceph-mgr1 初始化为 radosGW 服务:
[cephadmin@ceph-deploy ~]$ cd ceph-cluster/
[cephadmin@ceph-deploy ceph-cluster]$ ceph-deploy rgw create ceph-mgr2
[cephadmin@ceph-deploy ceph-cluster]$ ceph-deploy rgw create ceph-mgr1
#验证radosgw服务状态
#验证radosgw服务进程 ：
root@ceph-mgr1:~# ps -ef|grep radosgw
ceph 3940 1 0 20:00 ? 00:00:17 /usr/bin/radosgw -f --cluster ceph --name client.rgw.ceph-mgr1 --setuser ceph --setgroup ceph
root 4640 2944 0 20:48 pts/0 00:00:00 grep --color=auto radosgw
#radosgw的存储池类型
#查看默认 radosgw 的存储池信息：

#验证RGW zone 信息

#radosgw服务高可用配置
