一、Ceph新的OSD节点上的操作

1.1 配置ceph的yum源

cat /etc/yum.repos.d/ceph-aliyun.repo

[ceph]
name=ceph
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/x86_64/
gpgcheck=0
priority =1

[ceph-noarch]
name=cephnoarch
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/noarch/
gpgcheck=0
priority =1

[ceph-source]
name=Ceph source packages
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/SRPMS
gpgcheck=0
priority=1

1.2 配置ceph的安装包

yum -y install ceph ceph-radosgw

二、管理节点上的操作

# ssh-copy-id hz01-dev-ops-wanl-01
# ceph-deploy disk list hz01-dev-ops-wanl-01
# ceph-deploy disk zap hz01-dev-ops-wanl-01:vdb
# ceph-deploy osd prepare hz01-dev-ops-wanl-01:vdb
# ceph-deploy osd activate hz01-dev-ops-wanl-01:vdb1
# cd /my-cluster
# ceph-deploy admin hz01-dev-ops-wanl-01

查看ceph的状态：

2.1 查看ceph的状态：ceph -s
