一 摘要
本文是基於centos7.6 版使用ceph-deploy 工具 安裝ceph nautilus 版本。
二 環境
（一）操作系統版本
[root@ceph ~]# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)
[root@ceph ~]# uname -a
Linux ceph.novalocal 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@ceph ~]#
（二）ceph 版本
（三）部署規划
| 主機名 | IP | 磁盤 | 角色 |
|---|---|---|---|
| ceph001 | 172.31.185.127 | 系統盤：/dev/vda 數據盤：/dev/vdb | 時間服務器，ceph-deploy,monitor,mgr,mds,osd |
| ceph002 | 172.31.185.198 | 系統盤：/dev/vda 數據盤：/dev/vdb | monitor,mgr,mds,osd |
| ceph003 | 172.31.185.203 | 系統盤：/dev/vda 數據盤：/dev/vdb | monitor,mgr,mds,osd |
三 部署實施
(一) 基礎安裝
以下安裝，若無特殊說明，三台節點均需要安裝。
3.1.1 設置主機名稱
以172.31.185.127 為例子
[root@ceph ~]# hostnamectl set-hostname ceph001
[root@ceph ~]#
PS:
172.31.185.198 hostnamectl set-hostname ceph002
172.31.185.203 hostnamectl set-hostname ceph003
3.1.2 關閉防火牆
[root@ceph ~]# systemctl stop firewalld | systemctl disable firewalld | systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld(1)
[root@ceph ~]#
3.1.3 關閉selinux
[root@ceph001 ~]# cp /etc/selinux/config /etc/selinux/config.bak.orig
[root@ceph001 ~]# sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config
[root@ceph001 ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@ceph001 ~]#
3.1.4 修改hosts文件
[root@ceph001 ~]# cp /etc/hosts /etc/hosts.bak.orig
[root@ceph001 ~]# vi /etc/hosts
新增
172.31.185.127 ceph001
172.31.185.198 ceph002
172.31.185.203 ceph003
3.1.5 重啟虛機
[root@ceph001 ~]# reboot
3.1.6 配置時間服務
因為centos7 一般默認安裝了chrony ，若沒有安裝直接 yum install chrony
3.1.6.1 配置時間服務器server 端
172.31.185.127 作為時間服務器server
3.1.6.1.1 修改配置/etc/chrony.conf
[root@ceph001 ~]# cp /etc/chrony.conf /etc/chrony.conf.bak.orig
3.1.6.2 配置時間服務器client 端
3.1.7 配置ceph 源
根據操作系統版本以及需要安裝的ceph 版本配置ceph 源
vim cephcentos7.repo
[Ceph]
name=Ceph packages for $basearch
baseurl=http://mirrors.aliyun.com/ceph/rpm-nautilus/el7/$basearch
enabled=1
gpgcheck=0
type=rpm-md
gpgkey=https://mirrors.aliyun.com/ceph/keys/release.asc
priority=1
[Ceph-noarch]
name=Ceph noarch packages
baseurl=http://mirrors.aliyun.com/ceph/rpm-nautilus/el7/noarch
enabled=1
gpgcheck=0
type=rpm-md
gpgkey=https://mirrors.aliyun.com/ceph/keys/release.asc
priority=1
[ceph-source]
name=Ceph source packages

enabled=1
gpgcheck=0
type=rpm-md
gpgkey=https://mirrors.aliyun.com/ceph/keys/release.asc
priority=1
給另外兩台機器也配置上
[root@ceph001 yum.repos.d]# scp /etc/yum.repos.d/cephcentos7.repo root@ceph002:/etc/yum.repos.d/

[root@ceph001 yum.repos.d]#
3.1.8 創建部署用戶cephadmin
三台節點都要創建該用戶，並設置sudo
[root@ceph001 yum.repos.d]# useradd cephadmin
[root@ceph001 ~]# echo "cephnau@2020" | passwd --stdin cephadmin
Changing password for user cephadmin.
passwd: all authentication tokens updated successfully.
[root@ceph001 ~]#
[root@ceph001 yum.repos.d]# echo "cephadmin ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/cephadmin
cephadmin ALL = (root) NOPASSWD:ALL
[root@ceph001 yum.repos.d]# chmod 0440 /etc/sudoers.d/cephadmin
[root@ceph001 yum.repos.d]#
(二) 部署節點基礎安裝
此處部署節點是ceph001 節點即ceph001
3.2.1 配置cephadmin用戶ssh免密登錄
部署節點上cephadmin 能夠免密登錄到三個ceph 集群集群 ceph001,ceph002,ceph003
[root@ceph001 ~]# su - cephadmin

[cephadmin@ceph001 ~]$ ssh-copy-id cephadmin@ceph003
(三) 部署ceph
3.3.1 部署節點安裝ceph-deploy
在部署節點ceph001 上使用cephadmin 用戶安裝ceph-deploy
3.3.1.1 下載安裝包到本地
將這些安裝包下載到本地，為以后的離線安裝做准備。
sudo yum -y install --downloadonly --downloaddir=/home/cephadmin/software/cephcentos7/ceph-deploy/ ceph-deploy python-pip
[cephadmin@ceph001 cephcentos7]$ cd ceph-deploy/
[cephadmin@ceph001 ceph-deploy]$ pwd
/home/cephadmin/software/cephcentos7/ceph-deploy
[cephadmin@ceph001 ceph-deploy]$ ll
total 2000
-rw-r--r-- 1 root root 292428 Apr 10 2020 ceph-deploy-2.0.1-0.noarch.rpm
-rw-r--r-- 1 root root 1752207 Jan 29 2020 python2-pip-8.1.2-12.el7.noarch.rpm
[cephadmin@ceph001 ceph-deploy]$
3.3.1.2 安裝ceph-deploy python-pip
[cephadmin@ceph001 ceph-deploy]$ pwd
/home/cephadmin/software/cephcentos7/ceph-deploy
[cephadmin@ceph001 ceph-deploy]$ ll
total 2000
-rw-r--r-- 1 root root 292428 Apr 10 2020 ceph-deploy-2.0.1-0.noarch.rpm
-rw-r--r-- 1 root root 1752207 Jan 29 2020 python2-pip-8.1.2-12.el7.noarch.rpm
[cephadmin@ceph001 ceph-deploy]$ sudo yum localinstall *.rpm
3.3.2 安裝ceph包
所有ceph 集群節點都需安裝
采用yum 方式安裝ceph 包，把相關依賴全部下載下來
3.3.2.1 下載安裝包到本地
sudo yum -y install --downloadonly --downloaddir=/home/cephadmin/software/cephcentos7/ceph/ ceph ceph-radosgw
3.3.2.2 安裝ceph 包
三台節點安裝ceph
[cephadmin@ceph001 ceph]$ sudo yum localinstall *.rpm
3.3.3 創建集群
在ceph-deploy 部署節點 操作
3.3.3.1 安裝ceph軟件(標題名稱要改)
部署節點上
[cephadmin@ceph001 ~]$ mkdir /home/cephadmin/cephcluster
[cephadmin@ceph001 ~]$ ll
total 0
drwxrwxr-x 2 cephadmin cephadmin 6 Nov 30 16:48 cephcluster
drwxr-xr-x 4 root root 58 Nov 30 16:45 software
[cephadmin@ceph001 ~]$ cd cephcluster/
[cephadmin@ceph001 cephcluster]$ pwd
/home/cephadmin/cephcluster
[cephadmin@ceph001 cephcluster]$ ceph-deploy new ceph001 ceph002 ceph003
[ceph_deploy.conf][DEBUG ] found configuration file at: /home/cephadmin/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (2.0.1): /bin/ceph-deploy new ceph001 ceph002 ceph003

[ceph_deploy.cli][INFO ] cluster : ceph
[ceph_deploy.cli][INFO ] ssh_copykey : True
[ceph_deploy.cli][INFO ] mon : ['ceph001', 'ceph002', 'ceph003']
[ceph_deploy.cli][INFO ] public_network : None
[ceph_deploy.cli][INFO ] ceph_conf : None
[ceph_deploy.cli][INFO ] cluster_network : None
[ceph_deploy.cli][INFO ] default_release : False
[ceph_deploy.cli][INFO ] fsid : None
[ceph_deploy.new][DEBUG ] Creating new cluster named ceph
。。。。
以上可見 本次集群名是ceph
並生成以下文件
[cephadmin@ceph001 cephcluster]$ ll
total 16
-rw-rw-r-- 1 cephadmin cephadmin 247 Nov 30 16:50 ceph.conf
-rw-rw-r-- 1 cephadmin cephadmin 5231 Nov 30 16:50 ceph-deploy-ceph.log
-rw------- 1 cephadmin cephadmin 73 Nov 30 16:50 ceph.mon.keyring
[cephadmin@ceph001 cephcluster]$
PS:
ceph-deploy –cluster {cluster-name} new node1 node2 //創建一個自定集群名稱的ceph集群，默
認為 ceph
修改ceph.conf 新增網絡配置
[global]
fsid = 69002794-cf45-49fa-8849-faadae48544f
mon_initial_members = ceph001, ceph002, ceph003
mon_host = 172.31.185.127,172.31.185.198,172.31.185.203
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
public network = 172.31.185.0/24
cluster network = 172.31.185.0/24
~
public network = 172.31.185.0/24
cluster network = 172.31.185.0/24
應該使用兩個不同的網段，因為我這里只有一張網卡。
比如eth0 ，eth1
3.3.3.2 集群配置初始化，生成所有密鑰
[cephadmin@ceph001 cephcluster]$ ceph-deploy mon create-initial #配置初始 monitor(s)、並收集所有密鑰
[ceph_deploy.conf][DEBUG ] found configuration file at: /home/cephadmin/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (2.0.1): /bin/ceph-deploy mon create-initial

[cephadmin@ceph001 cephcluster]$ pwd
/home/cephadmin/cephcluster
[cephadmin@ceph001 cephcluster]$
3.3.3.3 配置信息分發到各節點
配置信息將拷貝到各節點/etc/ceph 目錄下
[cephadmin@ceph001 cephcluster]$ ceph-deploy admin ceph001 ceph002 ceph003 #配置信息拷貝到三台節點
檢查是否可以
切換到root 賬號
[root@ceph001 ~]# ceph -s

三個節點都需要執行 sudo chown -R cephadmin:cephadmin /etc/ceph
3.3.3.4 配置osd
首先查看數據盤名稱,三個節點都要看
