分布式存储-ceph部署jewel版本

准备

1，所有节点添加域名解析，设置root无秘钥登录
2，所有节点（包括客服端）创建cent用户

#useradd cent && echo "123" | passwd --stdin cent
设置超级权限
#echo -e 'Defaults:cent !requiretty\ncent ALL = (root) NOPASSWD:ALL' | tee /etc/sudoers.d/ceph
#chmod 440 /etc/sudoers.d/ceph

3,在部署节点切换为cent用户，设置无密钥登陆各节点包括客户端节点
4,在部署节点切换为cent用户，在cent用户家目录，设置如下文件( define all nodes and users ):

$vi ~/.ssh/config

Host pikachu4
	Hostname pikachu4
	User cent
Host pikachu1
	Hostname pikachu1
	User cent
Host pikachu3
	Hostname pikachu3
	User cent

修改权限
$chmod 600 ~/.ssh/config

所有节点配置国内ceph源

1，all-node（包括客户端）

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

[ceph]
name=ceph-install
baseurl=https://mirrors.aliyun.com/centos/7/storage/x86_64/ceph-jewel/
enable=1
gpgcheck=0

2，需要到https://mirrors.aliyun.com/centos/7/storage/x86_64/ceph-jewel/下载下面的rpm包（贴心小提示：安包之前快个照）
