1、由于尝试阿里、清华、163等源，在yum安装时都会出现问题，最后选用网友一种将yum源拉去到本地做镜像的方式。
下载ceph nautilus版本yum源（最新版），安装ftp服务器
yum install -y vsftpd wget lrzsz
systemctl start vsftpd
下载这两个文件夹里对应 14.2.5-0.el7 的 rpm
noarch/ 14-Jan-2020 23:21
x86_64/ 14-Jan-2020 23:24
1.1 下载aarch64文件夹对应版本的rpm文件：(物理机)
]# mkdir /var/ftp/pub/ceph
]# cd /var/ftp/pub/ceph
ceph]# mkdir ceph noarch
ceph]# ls
ceph noarch
进入/var/ftp/pub/ceph/ceph文件夹，创建x86_64.txt
ceph]# vim x86_64.txt
注意：用鼠标全选复制网页：
"https://mirrors.aliyun.com/ceph/rpm-nautilus/el7/x86_64/"
上面所有的文字粘贴到x86_64.txt
如下图：
1.2 编写脚本，将最新14.2.8拉去下来
[root@ceph01 ceph]# cat get.sh #!/bin/bash rpm_file=/var/ftp/pub/ceph/ceph/$1.txt rpm_netaddr=https://mirrors.aliyun.com/ceph/rpm-nautilus/el7/$1 for i in `cat $rpm_file` do if [[ $i =~ rpm ]] && [[ $i =~ 14.2.8-0 ]] then wget $rpm_netaddr/$i fi done
1.3 执行脚本，下载rpm文件
ceph]# bash get.sh x86_64
查看:
ceph]# ls
ceph-14.2.8-0.el7.x86_64.rpm
ceph-base-14.2.8-0.el7.x86_64.rpm
ceph-common-14.2.8-0.el7.x86_64.rpm
ceph-debuginfo-14.2.8-0.el7.x86_64.rpm
cephfs-java-14.2.8-0.el7.x86_64.rpm
ceph-fuse-14.2.8-0.el7.x86_64.rpm
1.4 在noarch文件夹内也下载对应的noarch.rpm包，复制网页时有些不全，可自己补充
[root@ceph01 ceph]# cd ../noarch/ You have new mail in /var/spool/mail/root [root@ceph01 noarch]# cat get.sh #!/bin/bash rpm_file=/var/ftp/pub/ceph/noarch/$1.txt rpm_netaddr=https://mirrors.aliyun.com/ceph/rpm-nautilus/el7/$1 for i in `cat $rpm_file` do if [[ $i =~ rpm ]] && [[ $i =~ 14.2.8-0 ]] then wget $rpm_netaddr/$i fi done
1.5 （所有节点都要）将下载的rpm文件制作本地yum源，给虚拟机ceph集群使用（此本地源在安装完后会被保存，新的ceph.repo文件为官方源）
[root@ceph01 ~]# cat /etc/yum.repos.d/ceph.repo [ceph] name=ceph repo baseurl=ftp://10.10.20.55/pub/ceph/ceph gpgcheck=0 enable=1 [ceph-noarch] name=Ceph noarch packages baseurl=ftp://10.10.20.55/pub/ceph/noarch gpgcheck=0 enable=1
2 准备集群环境
2.1 确认主机名，设置hosts配置文件按
（所有节点执行）
[root@ceph01 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.10.20.55 ceph01 10.10.20.66 ceph02 10.10.20.77 ceph03
2.2 创建用户并设置免密登陆
（所有节点执行）创建用户
useradd -d /home/admin -m admin echo "123456" | passwd admin --stdin #sudo权限 echo "admin ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/admin sudo chmod 0440 /etc/sudoers.d/admin
设置免密登陆
[root@ceph01 ~]# su - admin [admin@ceph01 ~]$ ssh-keygen [admin@ceph01 ~]$ ssh-copy-id admin@ceph01 [admin@ceph01 ~]$ ssh-copy-id admin@ceph02 [admin@ceph01 ~]$ ssh-copy-id admin@ceph03
2.3 配置NTP时间同步服务器
（所有节点执行）
yum -y install ntpdate ntpdate -u cn.ntp.org.cn crontab -e */20 * * * * ntpdate -u cn.ntp.org.cn > /dev/null 2>&1 systemctl reload crond.service
2.4 磁盘准备（所有节点准备）
虚拟机新增三块盘
/dev/sdb 用于日志盘
/dev/sdc /dev/sdd 用于数据盘
3. 开始部署集群环境
安装部署工具ceph-deploy
创建ceph集群
准备日志磁盘分区
创建OSD存储空间
查看ceph状态，验证
3.1 部署前安装
所有节点执行
]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo ]# yum clean all;yum repolist ]# yum -y install ceph-release ]# rm -rf /etc/yum.repos.d/ceph.repo.rpmnew
ceph01:
创建目录,并安装ceph-deploy
]# su - admin
]$ mkdir ceph-cluster
]$ cd ceph-cluster/
]$ sudo yum install ceph-deploy python-pip python-setuptools -y
]$ ceph-deploy --version
2.0.1
开始部署集群
[admin@ceph01 ceph-cluster]$ ceph-deploy new ceph01 ceph02 ceph03
[admin@ceph01 ceph-cluster]$ ls
ceph.conf ceph-deploy-ceph.log ceph.mon.keyring
[admin@ceph01 ceph-cluster]$ cat ceph.conf
[global]
fsid = b1b27e22-fc76-4a56-8a45-30bb87f6207c
mon_initial_members = ceph01, ceph02, ceph03
mon_host = 10.10.20.55,10.10.20.66,10.10.20.77
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
View Code
修改ceph.conf配置文件，添加如下配置：
public network = 10.10.20.0/24 osd pool default size = 3 osd pool default min size = 2 osd pool default pg num = 128 osd pool default pgp num = 128 osd pool default crush rule = 0 osd crush chooseleaf type = 1 max open files = 131072 ms bind ipv6 = false [mon] mon clock drift allowed = 10 mon clock drift warn backoff = 30 mon osd full ratio = .95 mon osd nearfull ratio = .85 mon osd down out interval = 600 mon osd report timeout = 300 mon allow pool delete = true [osd] osd recovery max active = 3 osd max backfills = 5 osd max scrubs = 2 osd mkfs type = xfs osd mkfs options xfs = -f -i size=1024 osd mount options xfs = rw,noatime,inode64,logbsize=256k,delaylog filestore max sync interval = 5 osd op threads = 2
3.2 开始安装ceph包
[admin@ceph01 ceph-cluster]$ sudo yum install -y ceph ceph-radosgw
[admin@ceph02 ~]$ sudo yum install -y ceph ceph-radosgw
[admin@ceph03 ~]$ sudo yum install -y ceph ceph-radosgw
查看ceph版本
[admin@ceph01 ceph-cluster]$ ceph --version
ceph version 14.2.8 (2d095e947a02261ce61424021bb43bd3022d35cb) nautilus (stable)
给所有节点安装软件包（ceph01操作），操作前检查/etc/yum.repo.d/下是否有ceph.repo.rpmnew 或ceph.repo.rpmsave
由于网络或镜像原因，一次不成功多执行几次，每次执行先删除ceph.repo.rpmnew 和 ceph.repo.rpmsave文件
[admin@ceph01 ceph-cluster]$ ceph-deploy install ceph01 ceph02 ceph03
部署初始的monitors，并获得keys

创建OSD存储空间（仅node1操作即可）
# 创建osd存储设备，vdc为集群提供存储空间，vdb1提供JOURNAL缓存
# 一个存储设备对应一个缓存设备，缓存需要SSD，不需要很大
