一、ceph介绍
Ceph 是一个开源的分布式存储系统， 同时支持对象存储、 块设备、 文件系统。ceph 支持 EB(1EB=1,000,000,000GB)级别的数据存储， ceph 把每一个待管理的数据流(文件等数据)切分为一到多个固定大小(默认 4 兆)的对象数据， 并以其为原子单元(原子是构成元素的最小单元)完成数据的读写。ceph 的底层存储服务是由多个存储主机(host)组成的存储集群， 该集群也被称之为RADOS(reliable automatic distributed object store)存储集群， 即可靠的、 自动化的、 分布式的对象存储系统。 librados 是 RADOS 存储集群的 API， 支持 C/C++/JAVA/python/ruby/php/go等编程语言客户端。
ceph角色定义
LIBRADOS、 RADOSGW、 RBD 和 Ceph FS 统称为 Ceph 客户端接口。 RADOSGW、RBD、 Ceph FS 是基于 LIBRADOS 提供的多编程语言接口开发的。 一个 ceph 集群的组成部分：
-
若干的 Ceph OSD（对象存储守护程序）
-
至少需要一个 Ceph Monitors 监视器（1,3,5,7...）
-
两个或以上的 Ceph 管理器 managers， 运行 Ceph 文件系统客户端时
-
还需要高可用的 Ceph Metadata Server(文件系统元数据服务器)。
-
RADOS cluster:由多台 host 存储服务器组成的 ceph 集群
-
OSD(Object Storage Daemon)： 每台存储服务器的磁盘组成的存储空间
-
Mon(Monitor)： ceph 的监视器,维护 OSD 和 PG 的集群状态， 一个 ceph 集群至少要有一个mon， 可以是一三五七等等这样的奇数个。
-
Mgr(Manager)： 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等。
Monitor(ceph-mon) ceph 监视器 在一个主机上运行的一个守护进程，用于维护集群状态映射(maintains maps of thecluster state)，比如 ceph 集群中有多少存储池、每个存储池有多少PG以及存储池和 PG的映射关系等，monitor map, manager map, the OSD map, the MDS map, and theCRUSH map，这些映射是 Ceph 守护程序相互协调所需的关键群集状态， 此外监视器还负责管理守护程序和客户端之间的身份验证(认证使用 cephX 协议)。 通常至少需要三个监视器才能实现冗余和高可用性。
Managers(ceph-mgr)的功能： 在一个主机上运行的一个守护进程，Ceph Manager守护程序（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。CephManager守护程序还托管基于python的模块来管理和公开Ceph集群信息，包括基于Web的Ceph仪表板和REST API。高可用性通常至少需要两个管理器。
Ceph OSDs(对象存储守护程序 ceph-osd)： 提供存储数据，操作系统上的一个磁盘就是一个OSD守护程序，OSD用于处理ceph集群数据复制、恢复、重新平衡，并通过检查其他Ceph OSD守护程序的心跳来向Ceph监视器和管理器提供一些监视信息。通常至少需要3个Ceph OSD才能实现冗余和高可用性。
MDS(ceph 元数据服务器 ceph-mds)： 代表ceph文件系统(NFS/CIFS)存储元数据，(即Ceph块设备和Ceph对象存储不使用MDS)
Ceph 的管理节点： 1.ceph 的常用管理接口是一组命令行工具程序，例如rados、ceph、rbd等命令，ceph 管理员可以从某个特定的ceph-mon节点执行管理操作 2.推荐使用部署专用的管理节点对ceph进行配置管理、升级与后期维护，方便后期权限管理，管理节点的权限只对管理人员开放，可以避免一些不必要的误操作的发生。
ceph 逻辑组织架构
-
Pool： 存储池、分区，存储池的大小取决于底层的存储空间。
-
PG(placement group)：一个 pool 内部可以有多个PG存在， pool和PG都是抽象的逻辑概念，一个pool中有多少个PG可以通过公式计算。
-
OSD(Object Storage Daemon,对象存储设备):每一块磁盘都是一个 osd， 一个主机由一个或多个 osd 组成.
-
ceph 集群部署好之后,要先创建存储池才能向ceph写入数据，文件在向ceph保存之前要先进行一致性hash计算，计算后会把文件保存在某个对应的PG的，此文件一定属于某个pool的一个PG，在通过PG保存在OSD上。数据对象在写到主 OSD 之后再同步对从OSD以实现数据的高可用。
ceph存储适用场景
块存储： 块存储在使用的时候需要格式化为指定的文件系统， 然后挂载使用， 其对操作系统的兼容性相对比较好(可以格式化为操作系统支持的文件系统)， 挂载的时候通常是每个服务单独分配独立的块存储， 即各服务的块存储是独立且不共享使用的， 如 Redis 的 master 和 slave 的块存储是独立的、 zookeeper 各节点的快存储是独立的、 MySQL 的 master 和 slave 的块存储是独立的、 也可以用于私有云与公有云的虚拟机的系统盘和云盘等场景， 此类场景适合使用块存储。 cephFS： 对于需要在多个主机实现数据共享的场景，比如多个nginx读取由多个tomcat写入到存储的数据，可以使用cephFS。 对象存储： 而对于数据不会经常变化、删除和修改的场景，如短视频、APP下载等，可以使用对象存储

git clone https://github.com/ceph/ceph-deploy.git cd ceph-deploy python3 setup.py install
2.3、添加ceph apt源
[root@ceph-deploy ~]# vi /etc/ansible/hosts [root@ceph-deploy ~]# cat /etc/ansible/hosts
[vm] 172.16.88.100 172.16.88.101 172.16.88.102 172.16.88.103 172.16.88.111 172.16.88.112 172.16.88.121 172.16.88.122 172.16.88.123

2.4、创建cephadmin用户
[root@ceph-deploy ~]# ansible 'vm' -m shell -a "groupadd -r -g 2088 cephadmin && useradd -r -m -s /bin/bash -u 2088 -g 2088 cephadmin && echo cephadmin:123456 | chpasswd"
设置cephadmin 具备sudo权限
[root@ceph-deploy ~]# ansible 'vm' -m shell -a "echo 'cephadmin ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers"
验证cephadmin是否具备sudo 权限
[root@ceph-deploy ~]# cat /etc/sudoers # # This file MUST be edited with the 'visudo' command as root. # # Please consider adding local content in /etc/sudoers.d/ instead of # directly modifying this file. # # See the man page for details on how to write a sudoers file. # Defaults env_reset Defaults mail_badpass Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin" # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification root ALL=(ALL:ALL) ALL # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL # See sudoers(5) for more information on "#include" directives: #includedir /etc/sudoers.d cephadmin ALL=(ALL) NOPASSWD: ALL [root@ceph-deploy ~]# su cephadmin cephadmin@ceph-deploy:/root$ cephadmin@ceph-deploy:/root$ cephadmin@ceph-deploy:/root$ cephadmin@ceph-deploy:/root$ sudo su - [root@ceph-deploy ~]# [root@ceph-deploy ~]#
2.5、创建cephadmin密钥并推送
[root@ceph-deploy ~]# su cephadmin cephadmin@ceph-deploy:/root$ cephadmin@ceph-deploy:/root$ cephadmin@ceph-deploy:/root$ cephadmin@ceph-deploy:/root$ ssh-keygen Generating public/private rsa key pair.

cephadmin@ceph-deploy:~$ vi ssh-key-push.sh cephadmin@ceph-deploy:~$ cat ssh-key-push.sh
#!/bin/bash
for i in {100..123};
do
sshpass -p '123456' ssh-copy-id -o StrictHostKeyChecking=no -i /home/cephadmin/.ssh/id_rsa -p 22 cephadmin@172.16.88.$i;
done
三、部署ceph集群
3.1、在管理节点初始化 mon 节点
cephadmin@ceph-deploy:~$ mkdir ceph-cluster cephadmin@ceph-deploy:~/ceph-cluster$ sudo apt-get install python2.7 -y cephadmin@ceph-deploy:~/ceph-cluster$ sudo ln -sv /usr/bin/python2.7 /usr/bin/python2
3.2、创建ceph-mon1节点
cephadmin@ceph-deploy:~/ceph-cluster$ ceph-deploy new --cluster-network 192.168.122.0/24 --public-network 172.16.88.0/24 ceph-mon1.example.local

[ceph_deploy.new][DEBUG ] Writing monitor keyring to ceph.mon.keyring... [ceph_deploy.new][DEBUG ] Writing initial config to ceph.conf...
3.3、初始ceph-node节点
cephadmin@ceph-deploy:~/ceph-cluster$ ceph-deploy install --no-adjust-repos --nogpgcheck ceph-node1 ceph-node2 ceph-node3 此过程会在指定的ceph-node节点按照串行的方式逐个服务器安装ceph-base、ceph-common等组件包：
3.4、安装ceph-mon节点

验证ceph-mon
验证在mon定节点已经自动安装并启动了ceph-mon服务,并且后期在ceph-deploy节点初始化目录会生成一些bootstrap、ceph、mds、mgr、osd、rgw 等服务的keyring认证文件,这些初始化文件拥有对 ceph 集群的最高权限， 所以一定要保存好
3.5、分发admin密钥到node节点
cephadmin@ceph-deploy:~/ceph-cluster$ ceph-deploy admin ceph-node1 ceph-node2 ceph-node3

验证node节点密钥
认证文件的属主和属组为了安全考虑，默认设置为了root 用户和root组，如果需要ceph用户也能执行ceph 命令,那么就需要对ceph 用户进行授权
