ceph学习
ceph简介和特性
ceph时一个多版本存储系统，它把每一个待管理的数据量切分为一到多个固定带下的对象数据，并以其为原子
单元完成数据存取。
对象数据的地处存储服务是由多个主机组成的存储集群，该集群也被称为RADOS存储集群即可靠、自动化、分布式对象存储系统。
ceph通过内部crush算法，实时方式计算除一个文件应该存储到那个存储对象里面，从而实现快速查找对象的一种方式。
librados是RADOS存储集群的api,它支持c、c++、java、python、ruby和PHP等编程语言
功能强大：ceph能够同时提供对象存储、块存储和文件存储三种存储服务的统一存储架构
可扩展性：ceph通过crush算法的寻址操作，有相当强大的扩展性。
高可用性：cpeh数据副本数量可以有管理员自定义，并通过crush算法指定副本的物理存储位置以分隔故障域，支持数据强一致性的特性也是ceph具有了高可靠性，可以忍受多种故障场景并自动尝试并进行修复
LIBRADOS --通过自编程的方式实现数据的存储能力
RADOSGW --通过标准的RESTFULL接口，提供一种云存储服务
RBD --将ceph提供的空间，模拟成一个个独立的块设备，当ceph环境部署完后，服务端准备好rbd接口
CFS --通过一个标准的文件系统接口来进行数据的存储
ceph组件
| 组件 | 解析 |
|---|---|
| Monitors | ceph Monitors守护进程（ceph-mon）维护集群状态的映射，包括监视器映射，管理器映射、OSD映射，MDS映射和CRUSH映射。监视器还负责管理守护进程和客户端的身份验证，通常至少需要三个监视器才能实现冗余和高可用性，基于paxos协议实现节点间的信息同步 |
| Managers | ceph管理器（守护进程ceph-mgr）负责跟踪运行时指标和ceph集群的当前状态，包括存储利用率，当前性能指标和系统负载。高可用性通常至少需要两个管理器，基于raft协议实现节点间的信息同步 |
| cephOSDS | ceph OSD（对象存储守护进程ceph-osd）存储数据，处理数据复制，回复，重新平衡，并通过检查其他osd守护进程的心跳来向ceph监视器和管理器提供一写监控信息，通常需要3个ceph OSD 来实现冗余和高可用性，本质上osd就是一个个host主机上存储磁盘 |
| MDSs | ceph元数据服务器，代表ceph文件系统存储元数据。ceph元数据服务器允许POSIX文件系统用户执行基本命令（ls, find等），而不会给ceph集群带来巨大负担 |
ceph网络模型
ceph生产环境一般分为两个网段：
公有网络：用于用户的数据通信
集群网络：用于集群内部的管理通信
ceph版本
x.0.z-开发版
x.1.z-候选版
x.2.z-稳定、修正版

ceph部署
| 部署方式 | 特点解析 |
|---|---|
| cephadm | 使用容器和systemd安装和管理ceph集群，并于CLI和仪表板GUI紧密集成，只支持octopus以后的新版本，当前官方推荐 |
| ceph-deploy | 一个基于python实现的快速部署集群的工具，此工具从Nautilus版后不再支持和测试，建议使用此工具 Nautilus 之前的旧版本。不支持 RHEL8、CentOS 8 或更新的操作系统。 |
| rook | 在k8s上运行ceph集群，同时还支持通过K8Sapi管理存储资源和配置，只支持 Nautilus 以后的新版本，不支持 RHEL8、CentOS 8 或更新的操作系统。 |
| ceph-ansible | 使用ansible部署和管理ceph集群，应用较广，但是从Nautilus 和octopus版没有集成对应的api，所以较新的管理功能和仪表板集成不可用 |
| ceph-salt | 使用salt和cephadm安装ceph |
| ceph-mon | 使用Juju（模型驱动的k8s生命周期管理器OLM）安装ceph |
| puppet-ceph | 通过puppet安装ceph |
| 二进制 | 手工安装 |
| windows图形 | 在windows主机上通过图形操作就可以进行部署 |
