（ceph集群安装请看上篇文章）

CEPH篇 块存储、文件存储和对象存储意义和差异及ubuntu20.4下 ceph安装_yaodunlin的博客-CSDN博客

各个work节点安装客户端

apt update

apt install ceph-common

K8S 客户端版本必须大于服务器版本   必须拷贝 这两个文件 ceph.client.admin.keyring  ceph.conf 到所有的K8S work节点

服务端拷贝配置文件过去

scp ceph.client.admin.keyring ceph.conf 这两个文件过去

chmod 644 /etc/ceph/ceph.c*
