This article is about how to quickly deploy ceph clusters. I think it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

The editor will demonstrate how to deploy a ceph distributed storage cluster on centos step by step. The goal is to create a two-node cluster on ceph-node1 and ceph-node2.

Operating system: Centos 7.3

Openstack:Ocata

Ceph:Jewel

Install Ceph

1: prepare repo

Yum clean all

Rm-rf / etc/yum.repos.d/*.repo

Wget-O / etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

Yum update-y

2: operating system configuration

Enable Ceph monitor OSD port

Disable Selinux

Setenforce 0

Install ntp

Yum install ntp ntpdate-y

Systemctl restart ntpdate.service

Systemctl restart ntpd.service

Systemctl enable ntpd.service ntpdate.service

Password-less access configuration

Configure password-free access between deploy nodes and other ceph nodes

Sudo su-

Ssh-keygen

Ssh-copy-id root@ceph-node2

Ssh-copy-id root@cloud

3: deploy Ceph cluster

Install ceph-deploy

Yum install ceph-deploy-y

Using Ceph-deploy to create Ceph Cluster

Mkdir / etc/ceph

Cd / etc/ceph

Ceph-deploy new ceph-node1

Install the CEO binary package

Ceph-deploy install-no-adjust-repos ceph-node1

Modify ceph configuration file

[global]

Fsid = 7bac6963-0e1d-4cea-9e2e-f02bbae96ba7

Mon_initial_members = ceph-node1

Mon_host = 192.168.1.101

Auth_cluster_required = cephx

Auth_service_required = cephx

Auth_client_required = cephx

Public network = 192.168.1.0 Compact 24

Create the first ceph monitor on ceph-node1

Ceph-deploy mon create-initial

Create an OSD on ceph-node1

Ceph-deploy disk list ceph-node1 (list disk)

Ceph-deploy disk zap ceph-node1:sdb ceph-node1:sdc ceph-node1:sdd

Ceph-deploy osd create ceph-node1:sdb ceph-node1:sdc ceph-node1:sdd

With the above steps, a ceph for all in one is successfully deployed. Check the status of the ceph.
