一 环境准备
1 安装虚拟机
pc机 1T硬盘 16G内存。
vmware workstation 15
创建 4台虚拟机, 网络为桥接。
编号 hostname ip 对应下图节点
ceph-1 dev-ceph1 192.168.199.175/24 admin-node
ceph-2 dev-ceph2 192.168.199.164/24 node1
ceph-3 dev-ceph3 192.168.199.105/24 node2
ceph-4 dev-ceph4 192.168.199.222/24 node3
2 配置源
yum源， 将/etc/yum.repo.d/CentOS* 移出bp目录备份；
编辑CentOS-Base.repo

3 ceph-1 安装ceph-deploy
sudo yum update && sudo yum install ceph-deploy
4 所有主机安装ntp，ssh和创建ceph用户。
ntp
yum install ntp ntpdate ntp-doc
openssh-server yum update 时已经安装。
创建ceph用户
ceph-1 ceph-2 ceph-3 ceph-4 创建 ceph用户 test-ceph
[root@dev-ceph2 yum.repos.d]# sudo useradd -d /home/test-ceph -m test-ceph
[root@dev-ceph2 yum.repos.d]# sudo passwd test-ceph
Changing password for user test-ceph.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@dev-ceph2 yum.repos.d]#
test-ceph 用户配置sudo权限
[root@dev-ceph4 yum.repos.d]# echo "test-ceph ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/test-ceph
test-ceph ALL = (root) NOPASSWD:ALL
[root@dev-ceph4 yum.repos.d]# sudo chmod 0440 /etc/sudoers.d/test-ceph
[root@dev-ceph4 yum.repos.d]#
5 各节点免密
ceph-1 管理节点。 创建ceph-admin用户。
A 生成密钥
[root@dev-ceph1 ~]# sudo useradd -d /home/ceph-admin -m ceph-admin
[root@dev-ceph1 ~]# sudo passwd ceph-admin
Changing password for user ceph-admin.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@dev-ceph1 ~]# su ceph-admin -l
[ceph-admin@dev-ceph1 ~]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/ceph-admin/.ssh/id_rsa):
Created directory '/home/ceph-admin/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/ceph-admin/.ssh/id_rsa.
Your public key has been saved in /home/ceph-admin/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:xU79sJfUL/5srMzy4jylqlfa3RgmQfD2IBTbXKdQ47c ceph-admin@dev-ceph1
The key's randomart image is:

| + *.= |
| o.*ooo+|
| .o.oo==oo|
+----[SHA256]-----+
[ceph-admin@dev-ceph1 ~]$
B 拷贝公钥到各个节点
拷贝到ceph-2
[ceph-admin@dev-ceph1 ~]$ ssh-copy-id -i /home/ceph-admin/.ssh/id_rsa.pub dev-ceph2
/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/ceph-admin/.ssh/id_rsa.pub"
/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
test-ceph@dev-ceph2's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'dev-ceph2'"
and check to make sure that only the key(s) you wanted were added.依次拷贝到ceph-3， ceph-4
ceph-1 上配置 ssh config文件
[ceph-admin@dev-ceph1 ~]$ cat ~/.ssh/config
Host dev-ceph2
Hostname dev-ceph2
User test-ceph
Host dev-ceph3
Hostname dev-ceph3
User test-ceph
Host dev-ceph4
Hostname dev-ceph4
User test-ceph
6 网络检查
A 各主机 网卡设置开机启动
[ceph-admin@dev-ceph1 ~]$ cat /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="dhcp"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="64725794-0775-426d-a6a9-48386e2293e9"
DEVICE="ens33"
ONBOOT="yes"
[ceph-admin@dev-ceph1 ~]$ 默认 ONBOOT 都是yes 不需要配置
B 各节点网络通 互ping
ping dev-ceph1
ping dev-ceph2
ping dev-ceph3
ping dev-ceph4
C 开端口6789
因为时测试， 直接禁用firewalld root用户操作
systemctl stop firewalld
systemctl disable firewalld
D 管理节点配置终端tty
如果配置了requiretty , 我们没有配置过， 忽略。
E 设置SELINUX
各节点 执行命令
sudo setenforce 0
F 配置包优先级
sudo yum install yum-plugin-priorities
二 集群安装
1 创建集群
ceph-1 管理节点 切换至ceph-admin 用户
[ceph-admin@dev-ceph1 ~]$ mkdir my-cluster
[ceph-admin@dev-ceph1 ~]$ cd my-cluster/
执行 ceph-deploy new -h 会报错 python 没有 pkg_rexxx包；
解决安装pip ， 方法 1 在pypi 上 下载 pip 源码包， 解压 python setup.py install 安装， 但可能有很多其他依赖。
方法2 在 rpmsearch 网站上搜索 el7 的 python-pip 包， 下载安装，只有一个python-setuptools rpm包。源里有直接安装。 然后 pip install distribute .
ceph-1 上 ceph-admin 用户创建 mon 节点
[ceph-admin@dev-ceph1 my-cluster]$ ceph-deploy new dev-ceph2
[ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph-admin/.cephdeploy.conf

[ceph-admin@dev-ceph1 my-cluster]$
2 安装ceph
在ceph-1 ceph-admin 用户
[ceph-admin@dev-ceph1 my-cluster]$ ceph-deploy install dev-ceph1 dev-ceph2 dev-ceph3 dev-ceph4 --no-adjust-repos
执行完后
[dev-ceph4][DEBUG ]
[dev-ceph4][DEBUG ] Complete!
[dev-ceph4][INFO ] Running command: sudo ceph --version
[dev-ceph4][DEBUG ] ceph version 10.2.11 (e4b061b47f07f583c92a050d9e84b1813a35671e)安装成功。
3 初始化mon
在ceph-1 ceph-admin 用户
[ceph-admin@dev-ceph1 my-cluster]$ ceph-deploy mon create-initial
[ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph-admin/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (2.0.1): /bin/ceph-deploy mon create-initial

[ceph_deploy.cli][INFO ] cluster : ceph
[ceph_deploy.cli][INFO ] func : <function mon at 0x7f53c4bde410>
到
[dev-ceph2][INFO ] Running command: sudo /usr/bin/ceph --connect-timeout=25 --cluster=ceph --name mon. --keyring=/var/lib/ceph/mon/ceph-dev-ceph2/keyring auth get client.bootstrap-rgw

结束。
[ceph-admin@dev-ceph1 my-cluster]$ ls
ceph.bootstrap-mds.keyring ceph.bootstrap-rgw.keyring ceph-deploy-ceph.log
ceph.bootstrap-mgr.keyring ceph.client.admin.keyring ceph.mon.keyring
ceph.bootstrap-osd.keyring ceph.conf
[ceph-admin@dev-ceph1 my-cluster]$
4 配置 osd 节点
登录到ceph-3 和ceph-4
[ceph-admin@dev-ceph1 my-cluster]$ ssh dev-ceph3
[test-ceph@dev-ceph3 ~]$ sudo mkdir /var/local/osd0
[test-ceph@dev-ceph3 ~]$ exit
logout
Connection to dev-ceph3 closed.
[ceph-admin@dev-ceph1 my-cluster]$ ssh dev-ceph4
[test-ceph@dev-ceph4 ~]$ sudo mkdir /var/local/osd1
[test-ceph@dev-ceph4 ~]$ exit
logout
Connection to dev-ceph4 closed.
[ceph-admin@dev-ceph1 my-cluster]$
装的版本10 版本的， 配置osd时 没有ceph-volume
所有节点 升级到14.2 版本
[root@dev-ceph4 ~]# yum install centos-release-ceph-nautilus
然后
[root@dev-ceph4 ~]# yum install ceph
然后 给ceph-3 和ceph-4 分别挂一个20G的盘 /dev/sdb
在 ceph-1 ceph-admin 用户
[ceph-admin@dev-ceph1 my-cluster]$ ceph-deploy osd create dev-ceph3 --data /dev/sdc
[ceph-admin@dev-ceph1 my-cluster]$ ceph-deploy osd create dev-ceph4 --data /dev/sdb
查看 osd 状态
[ceph-admin@dev-ceph1 my-cluster]$ ceph-deploy osd list dev-ceph3
[ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph-admin/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (2.0.1): /bin/ceph-deploy osd list dev-ceph3

在ceph-2 上查看ceph集群状态
[root@dev-ceph2 ~]# ceph -s
cluster:

health: HEALTH_WARN

看到
crush map has legacy tunables .... , 参考 https://github.com/rook/rook/issues/3138
no active mgr 则需要在ceph-1 ceph-admin 用户 做如下操作
ceph-admin@dev-ceph1 my-cluster]$ ceph-deploy mgr create dev-ceph1
[ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph-admin/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (2.0.1): /bin/ceph-deploy mgr create dev-ceph1

再在ceph-2 ，3，4 上查看 ceph -s
[root@dev-ceph2 ~]# ceph -s
cluster:

[root@dev-ceph2 ~]#
ceph集群 应该搭建成功了吧。 第一次搭建， 不足之处请大家指教， 参考的文章比较多， 主要是官方文档。
