This article is to share with you about how to install Ceph in CentOS7.0, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Background

Because rexray, the Ceph plug-in of docker, has certain requirements for the Ceph version, when the Ceph version is hammer (0.94.10), rexray cannot successfully create the rbd device. For CentOS 7 and above, the hammer version is installed by default, so we need to install a higher jewel version. The version of Ceph is available in.

Installation

For installation speed, we can choose domestic sources. The domestic sources that people usually use include:

NetEase http://mirrors.163.com/ceph

Http://mirrors.ustc.edu.cn/ceph of China University of Science and Technology

Ali http://mirrors.aliyun.com/ceph

Add sourc

Add a Ceph source to yum (here take NetEase source as an example).

$tee / etc/yum.repos.d/ceph.repo
