Ceph
deploy-ceph部署
投入使用ceph前，要知道一个很现实得问题，ceph对低版本内核得客户端使用非常不友好，低内核是指小于等于3.10.0-862，默认的centos7.5及以下的系统都是小于此类内核，无法正常使用ceph的文件存储（cephFS）块存储（RBD）。
ceph部署一定要考虑好版本问题，经测试如果想使用ceph16版本，那你的客户端操作系统内核小于3.10.0-862根本用不了，常见的centos7.5以下默认没升级的内核都是小于3.10.0-862，所以这一大批服务器使用ceph提供的rdb存储都会有问题，而且ceph已经不提供centos的16版本的ceph-common组件，也就是说ceph集群部署16版本，常见的客户端centos7系统只能使用15版本的ceph-common，虽说也可以使用，但也存在一定隐患毕竟不是同一版本客户端软件，目前推荐使用ceph15的最高版本，15版本的安装与16相同，只是ceph源不同。
以上说法不正确，ceph版本选择和客户端内核没有关系，是所有版本的ceph都不友好支持内核小于等于3.10.0-862（CentOS7.5）
环境
ubuntu 18.04b版本
ceph 16.10版本

服务器配置：服务器型号，cpu，内存，磁盘大小及磁盘类型必须完全一致，磁盘最好全ssd盘
1.系统环境初始化
1.1 修改主机名，DNS解析
sh
master01：
hostnamectl set-hostname ceph-master01
vi /etc/hostname
ceph-master01
master02：
hostnamectl set-hostname ceph-master02
vi /etc/hostname
ceph-master02
master03：
hostnamectl set-hostname ceph-master03
vi /etc/hostname
ceph-master03
vi /etc/hosts
10.0.0.217 ceph-master01.example.local ceph-master01
10.0.0.218 ceph-master02.example.local ceph-master02
10.0.0.219 ceph-master03.example.local ceph-master031.2 时间同步
所有服务器执行
sh
#修改时区
timedatectl set-timezone Asia/Shanghai
#时间同步
root@ubuntu:~# apt install ntpdate

root@ubuntu:~# crontab -e
crontab: installing new crontab
root@ubuntu:~# crontab -l
* * * * * ntpdate ntp.aliyun.com1.3 配置apt基础源与ceph源
所有服务器执行如下命令自动替换
sh
#基础源
sed -i "s@http://.*archive.ubuntu.com@http://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list
sed -i "s@http://.*security.ubuntu.com@http://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list
#ceph源
echo "deb https://mirrors.tuna.tsinghua.edu.cn/ceph/debian-pacific bionic main" >> /etc/apt/sources.list.d/ceph.list
echo "deb https://mirrors.tuna.tsinghua.edu.cn/ceph/debian-nautilus bionic main" >> /etc/apt/sources.list.d/ceph.list
#导入ceph源key，不然不能使用ceph源
wget -q -O- 'https://mirrors.tuna.tsinghua.edu.cn/ceph/keys/release.asc' | sudo apt-key add -
# ceph仓库为https的话需要安装下面，不然无法使用https源
apt install -y apt-transport-https ca-certificates curl software-properties-common
apt update1.4关闭selinux与防火墙
sh
# ufw disable1.5 创建 ceph 集群部署用户 cephadmin
推荐使用指定的普通用户部署和运行 ceph 集群，普通用户只要能以非交互方式执行 sudo 命令执行一些特权命令即可，新版的 ceph-deploy 可以指定包含 root 的在内只要可以执 行 sudo 命令的用户，不过仍然推荐使用普通用户，ceph 集群安装完成后会自动创建 ceph 用户 (ceph 集群默认会使用 ceph 用户运行各服务进程 ,如 ceph-osd 等 )，因此推荐 使用除了 ceph 用户之外的比如 cephuser**、**cephadmin 这样的普通用户去部署和 管理ceph 集群。
在包含 ceph-deploy 节点的存储节点、mon 节点和 mgr 节点等创建 cephadmin 用户.
sh
groupadd -r -g 2088 cephadmin && useradd -r -m -s /bin/bash -u 2088 -g 2088 cephadmin && echo cephadmin:chinadci888. | chpasswd各服务器允许 cephadmin 用户以 sudo 执行特权命令:
bash
~# echo "cephadmin ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers1.6分发密钥
deploy节点要与所有服务器mon，mgr，osd节点免密，本文这里只有三台服务器，mon,mgr,osd都混合一起部署，所以只免密了三台服务器
master01(deploy节点):
sh
su - cephadmin
ssh-keygen
ssh-copy-id cephadmin@ceph-master01
ssh-copy-id cephadmin@ceph-master02
ssh-copy-id cephadmin@ceph-master032. ceph部署
2.1 安装 ceph 部署工具
bash
cephadmin@ceph-master01:~$ apt-cache madison ceph-deploy

cephadmin@ceph-master01:~$ sudo apt install ceph-deploy2.2 初始化 mon 节点
Ubuntu 各服务器需要单独安装 Python2(mon，mgr，osd节点所有服务器必须做)：
sh
cephadmin@ceph-master01:~$ sudo apt install python2.7 -y
cephadmin@ceph-master01:~$ sudo ln -sv /usr/bin/python2.7 /usr/bin/python2ceph-master01:

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，后续需要发送给各个服务节点。

执行ceph -s 发现有健康告警
[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-7GVNxmHe-1693278451851)(Ceph.assets/image-20220906174218646.png)]
在其中一个mon节点执行：
sh
ceph config set mon auth_allow_insecure_global_id_reclaim false2.4 分发admin 秘钥
在 ceph-deploy 节点把配置文件和 admin 密钥拷贝至 Ceph 集群需要执行 ceph 管理命令的节点，从而不需要后期通过 ceph 命令对 ceph 集群进行管理配置的时候每次都需要指定ceph-mon 节点地址和 ceph.client.admin.keyring 文件,另外各 ceph-mon 节点也需要同步ceph 的集群配置文件与认证文件。
sh
cephadmin@ceph-master01:~# sudo apt install ceph-common -y #node 节点在初始化时已经安装发送admin密钥到deploy节点，默认分发到/etc/ceph/下， ceph.client.admin.keyring只需要存放在要执行ceph客户端命令下即可，同k8s kubeconfig文件，传到日常管理的ceph-deploy下
sh

一般情况下ceph.client.admin.keyring文件的权限为600，属主和属组为root，如果在集群内节点使用cephadmin用户直接直接ceph命令，将会提示无法找到/etc/ceph/ceph.client.admin.keyring文件，因为权限不足

#服务器上有两块ssd盘时，可以分别把block-db，block-wal存放到ssd盘中
ceph-deploy osd create {node} --data /dev/sdc --block-db /dev/sda --block-wal /dev/sdb
#服务器上只有一块硬盘时，只指定db的话存放ssd盘，没有指定waf存放位置，waf也会自动写到更快速的ssd盘上，和db共用
ceph-deploy osd create {node} --data /path/to/data --block-db /dev/sda
#第三种无意义
ceph-deploy osd create {node} --data /path/to/data --block-wal /dev/sda 这里采用最简单的第一种方案 单块磁盘，高性能的ceph集群可以使用第二种方案，ssd存放元数据与waf日志

bash
存取数据时，客户端必须首先连接至 RADOS 集群上某存储池，然后根据对象名称由相关的CRUSH 规则完成数据对象寻址。于是，为了测试集群的数据存取功能，这里首先创建一个用于测试的存储池 mypool，并设定其 PG 数量为 32 个。
$ ceph -h #一个更底层的客户端命令
$ rados -h #客户端命令创建 pool：
sh
cephadmin@ceph-master01:~# ceph osd pool create mypool 32 32
pool 'mypool' created
cephadmin@ceph-master01:/etc/ceph-cluster# sudo ceph osd pool ls
device_health_metrics
mypool
或者：
cephadmin@ceph-master01:/etc/ceph-cluster# rados lspools mypool
device_health_metrics
mypool
或者：
cephadmin@ceph-master01:/etc/ceph-cluster# ceph osd lspools
1 device_health_metrics
2 mypool上传数据
当前的 ceph 环境还没还没有部署使用块存储和文件系统使用 ceph，也没有使用对象存储的客户端，但是 ceph 的 rados 命令可以实现访问 ceph 对象存储的功能：
bash
cephadmin@ceph-master01:~# sudo rados put msg1 /var/log/syslog --pool=mypool列出数据
bash
cephadmin@ceph-master01:/etc/ceph-cluster# rados ls --pool=mypool
msg1文件信息
bash
cephadmin@ceph-master01:/etc/ceph-cluster# ceph osd map mypool msg1
osdmap e114 pool 'mypool' (2) object 'msg1' -> pg 2.c833d430 (2.10) -> up ([15,13,0], p15) acting ([15,13,0], p15)表示文件放在了存储池 id 为 2 的 c833d430 的 PG 上,10 为当前 PG 的 id, 2.10 表示数据是在 id 为 2 的存储池当中 id 为 10 的 PG 中存储，在线的 OSD 编号 15,13,10，主 OSD 为 5，活动的 OSD 15,13,10，三个 OSD 表示数据放一共 3 个副本，PG 中的 OSD 是 ceph 的 crush算法计算出三份数据保存在哪些 OSD。

3.1 RBD架构图
Ceph 可以同时提供 RADOSGW(对象存储网关)、RBD(块存储)、Ceph FS(文件系统存储)， RBD 即 RADOS Block Device 的简称，RBD 块存储是常用的存储类型之一，RBD 块设备类似磁盘可以被挂载，RBD 块设备具有快照、多副本、克隆和一致性等特性，数据以条带化的方式存储在 Ceph 集群的多个 OSD 中。
bash
条带化技术就是一种自动的将 I/O 的负载均衡到多个物理磁盘上的技术，条带化技术就是 将一块连续的数据分成很多小部分并把他们分别存储到不同磁盘上去。这就能使多个进程同 时访问数据的多个不同部分而不会造成磁盘冲突，而且在需要对这种数据进行顺序访问的时 候可以获得最大程度上的 I/O 并行能力，从而获得非常好的性能。[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-oA8BQbdY-1693278451859)(Ceph.assets/image-20220916200520085.png)]
3.2 创建存储池
bash
#创建存储池
root@ceph-master01:~# ceph osd pool create rbd-data1 32 32
pool 'rbd-data1' created
#存储池启用 rbd
root@ceph-master01:~# ceph osd pool application enable rbd-data1 rbd
enabled application 'rbd' on pool 'rbd-data1'
#初始化 rbd
root@ceph-master01:~# rbd pool init -p rbd-data13.3 创建img镜像
rbd 存储池并不能直接用于块设备，而是需要事先在其中按需创建映像（image），并把映像文件作为块设备使用。rbd 命令可用于创建、查看及删除块设备相在的映像（image)，以及克隆映像、创建快照、将映像回滚到快照和查看快照等管理操作。例如，下面的命令能 够在指定的 RBD 即 rbd-data1 创建一个名为 myimg1 的映像.
3.3.1 创建镜像
bash
root@ceph-master01:~# rbd create data-img1 --size 3G --pool rbd-data1 --image-format 2 --image-feature layering

]3.3.3 :镜像的特性
RBD默认开启的特性包括: layering/exlcusive lock/object map/fast diff/deep flatten
bash
#启用指定存储池中的指定镜像的特性
$ rbd feature enable exclusive-lock --pool rbd-data1 --image data-img1
$ rbd feature enable object-map --pool rbd-data1 --image data-img1
$ rbd feature enable fast-diff --pool rbd-data1 --image data-img1
#关闭指定存储池中的指定镜像的特性
$ rbd feature disable fast-diff --pool rbd-data1 --image data-img1
#验证镜像特性
$ rbd --image data-img1 --pool rbd-data1 info3.4 客户端使用RBD
客户端使用RBD需要两个条件：
一.安装ceph 客户端组件 ceph-common
二.ceph用户
3.4.1 客户端安装 ceph-common
客户端要想挂载使用 ceph RBD，需要安装 ceph 客户端组件 ceph-common，但是 ceph-common 不在 cenos 的 yum 仓库，因此需要单独配置 yum 源，并且centos只能安装最高的版本为Octopus版（15版本）
bash
#配置 yum 源：
$ yum install epel-release
$ yum install https://mirrors.aliyun.com/ceph/rpm-octopus/el7/noarch/ceph-release-1-1.el7.noarch.rpm -y
#下载ceph-common
$ yum install -y ceph-common

[root@xianchaonode1 ~]# 4.CephFS使用详解
ceph FS 即 ceph filesystem，可以实现文件系统共享功能(POSIX 标准), 客户端通过 ceph协议挂载并使用 ceph 集群作为数据存储服务器，http://docs.ceph.org.cn/cephfs/。 Ceph FS 需要运行 Meta Data Services(MDS)服务，其守护进程为 ceph-mds，ceph-mds 进程管理与 cephFS 上存储的文件相关的元数据，并协调对 ceph 存储集群的访问。
bash
在linux系统使用 ls 等操作查看某个目录下的文件的时候，会有保存在磁盘上的分区表 记录文件的名称、创建日期、大小、inode 及存储位置等元数据信息，在 cephfs 由于数据 是被打散为若干个离散的 object 进行分布式存储，因此并没有统一保存文件的元数据，而且将文件的元数据保存到一个单独的存储出 matedata pool，但是客户端并不能直接访问 matedata pool 中的元数据信息，而是在读写数的时候有 MDS(matadata server)进行处理， 读数据的时候有 MDS从 matedata pool加载元数据然后缓存在内存(用于后期快速响应其它 客户端的请求)并返回给客户端，写数据的时候有MDS 缓存在内存并同步到matedata pool。[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-t8sqZbcW-1693278451860)(Ceph.assets/1663655096199.png)]
4.1 部署MDS服务

4.2 创建CephFS mdetadata和data存储池
使用 CephFS 之前需要事先于集群中创建一个文件系统，并为其分别指定元数据和数据相关的存储池。下面创建一个名为 cephfs 的文件系统用于测试，它使用 cephfs-metadata 为 元数据存储池，使用 cephfs-data 为数据存储池.
bash
root@ceph-master01:~# ceph osd pool create cephfs-metadata 32 32
pool 'cephfs-metadata' created
root@ceph-master01:~# ceph osd pool create cephfs-data 64 64

客户端挂载有两种方式，一是内核空间一是用户空间，内核空间挂载需要内核支持 ceph模块（内核版本3.10.0-862以上，centos7.5默认内核），用户空间挂载需要安装 ceph-fuse，如果内核本较低而没有 ceph 模块（验证centos7.5及以上默认内核基本都有ceph模块，centos7.3以下默认内核未测试），那么可以安装 ceph-fuse 挂载，但是推荐使用内核模块挂载。

存储卷可以通过 kube-controller-manager 组件动态创建，适用于有状态服务需要多个存储卷的场合。 将 ceph admin 用户 key 文件定义为 k8s secret，用于 k8s 调用 ceph admin 权限动态创建存储卷，即不再需要提前创建好 image 而是 k8s 在需要使用的时候再调用 ceph 创建。

虽然官方并没有直接提供对Cephfs StorageClass的支持，但是社区给出了类似的解决方案 external-storage/ cephfs。
测试发现Cephfs StorageClass k8s1.20版本之后已经不能使用。按照这种方式会报错以下截图，网上的解决方案需要在kube-apiserver.yaml配置文件中添加--feature-gates=RemoveSelfLink=false，这个参数在k8s1.20版本之后已经移除，后续使用ceph-csi方式。
Cephfs StorageClass部署方案（不成功）：
