rpm -vih http:
//mirrors
.sohu.com
/fedora-epel/7/x86_64/e/epel-release-7-2
.noarch.rpm
添加yum ceph仓库
vim
/etc/yum
.repos.d
/ceph
.repo
[ceph]
name=Ceph noarch packages
baseurl=http:
//mirrors
.163.com
/ceph/rpm-hammer/el7/x86_64/
enabled=1
gpgcheck=1
type
=rpm-md
gpgkey=http:
//mirrors
.163.com
/ceph/keys/release
.asc
安装ceph-deploy,ceph（ceph所有节点都安装，ceph-deploy只需admin节点安装）
yum -y update && yum -y
install
--release hammer ceph ceph-deploy
|
1 生成相关的MOD信息 监控服务器 h5
|

3
|
[root@h5 xx]
# ceph-deploy new h5
[root@h5 xx]
# ls
ceph.conf ceph-deploy-ceph.log ceph.mon.keyring
|
2 要根据自己的情况修改配置文件ceph.conf
|
1
2
|
osd_pool_default_size = 2
##几个节点组成，默认是3
osd_pool_defaults_min_size = 1
##最小值是1
|
3 生成key 当客户端要链接到ceph服务器，需要用户名和密码
|

[root@h5 xx]
# ceph-deploy mon create-initial
[root@h5 myceph]
# ls
ceph.bootstrap-mds.keyring ceph.client.admin.keyring ceph.mon.keyring
ceph.bootstrap-osd.keyring ceph.conf
ceph.bootstrap-rgw.keyring ceph.log
|
4 开始准备配置OSD
|

mkdir
path1 path2
[root@h5 xx]
# ceph-deploy osd prepare h5:/path1 h6:/path2
[root@h5 xx]
# ceph-deploy osd activate h5:/path1 h6:/path2 ##激活
[ceph_deploy.osd][DEBUG ] Host h5 is now ready
for
osd use.
|
5 把key复制到各个节点上去
|
1
2
|
[root@h5 ceph]
# ceph-deploy admin h5 h6
[root@h5 ceph]
# ceph health ##健康性检查
|
6 生成元数据
|

|
[root@h5 ceph]
# ceph-deploy mds create h5
[root@h5 ceph]
# rados lspools
[root@h5 ceph]
# rados mkpool glance
[root@h5 ceph]
# rados rmpool glance glance --yes-i-really-really-mean-it ##删除
