更新epel最新源

yum install epel-release -y

新加ceph jewel 版本源

 
       vim /etc/yum.repos.d/ceph.repo 
      

 
           [ceph-noarch]
          
           name=Ceph noarch packages
          
           baseurl=https:

           priority=

更新系统软件

 
           sudo yum update
          

安装ceph-deploy

 
           sudo yum install ceph-deploy
          

在所有的ceph node节点里添加ceph_deploy用户

 
           sudo useradd -d /home/ceph_deploy -m ceph_deploy
          
           sudo passwd ceph_deploy

在所有的ceph node节点里给ceph_deploy用户添加sudo权限

 
           echo 
           "ceph_deploy ALL = (root) NOPASSWD:ALL" 
           | sudo tee /etc/sudoers.d/ceph_deploy
          
           sudo chmod 
           0440 
           /etc/sudoers.d/ceph_deploy

所有的ceph node添加互信

 
           sudo su ceph_deploy
          
           ssh-keygen
          
           ssh-copy-id ceph_deploy
           @ceph
           -node1
          
           ssh-copy-id ceph_deploy
           @ceph
           -node2
          
           ssh-copy-id ceph_deploy
           @ceph
           -node3

添加ssh config文件，格式如下：

vim ~/.ssh/config

vim ~/.ssh/config

 
           Host ceph-node1
          
           Hostname ceph-node1
          
           User ceph_deploy
          
           Host ceph-node2
          
           Hostname ceph-node2
          
           User ceph_deploy
          
           Host ceph-node3
          
           Hostname ceph-node3
          
           User ceph_deploy
