ssh-keygen

ssh-copy-id {username}@node1
ssh-copy-id root@ceph2
4. 安装部署器
添加YUM源

baseurl=http://mirrors.aliyun.com/ceph/rpm-luminous/el7/x86_64/
gpgcheck=0
[ceph-noarch]
name=cephnoarch
baseurl=http://mirrors.aliyun.com/ceph/rpm-luminous/el7/noarch/
gpgcheck=0
[ceph-source]
name=ceph-source
baseurl=http://mirrors.aliyun.com/ceph/rpm-luminous/el7/SRPMS/
gpgcheck=0

 

yum install ceph-deploy -y

5.建立目录
[root@ceph1 ~]# mkdir /etc/ceph
[root@ceph1 ~]# cd /etc/ceph/

yum install python-setuptools
6.建立新的CEPH
建立新文件夹

ceph-deploy new ceph1 ceph2

7.修改配置
vi ceph.conf
添加

osd pool default size = 2

public network = 172.20.10.8/28

ceph-deploy install {ceph-node} [{ceph-node} ...]

ceph-deploy install ceph1 ceph2

9 初始化监控节点

ceph-deploy mon create-initial
ceph -s
10 挂载
ceph-deploy disk zap ceph1 /dev/vdb 初始化

ceph-deploy disk zap ceph2 /dev/vdb

ceph-deploy osd create ceph1 --data /dev/vdb
ceph-deploy osd create ceph2 --data /dev/vdb
ceph-deploy mon create ceph2 安装监控
