1 Experimental environment

2 quickly install ceph

2.1 preparation work

* time synchronization of each node, preferably from a ntp server on the same private network

* ssh visits between nodes, which are not described in detail in this article

* the ip and hostname correspondence of each node is set, and the / etc/hosts file of each node is configured as follows

192.168.100.96 ceph2

192.168.100.97 ceph3

192.168.100.98 ceph4

* create a journal partition. An osd corresponds to a journal partition (only partitions are created, no file systems are created)

You can create a GPT partition with sgdisk

2.2 install the ceph-deploy tool

Apt-get install ceph-deploy on admin

Create a cluster directory and enter the cluster directory. The following operations are performed in the cluster directory.

Mkdir / etc/ceph

Cd / etc/ceph

Install the cluster node

Ceph-deploy install ceph2 ceph3 ceph4

Establish a cluster instance and initialize the monitoring node

Ceph-deploy new ceph2 ceph3 ceph4

Activate the monitoring node

Ceph-deploy mon create-initial

Create osd

Command format: ceph-deploy osd create node:data-path:journal-path

Ceph-deploy osd create ceph2:/dev/sdb:/dev/sdd1 ceph2:/dev/sdc:/dev/sdd2 ceph3:/dev/sdb:/dev/sdd1 ceph3:/dev/sdc:/dev/sdd2 ceph4:/dev/sdb:/dev/sdd1 ceph4:/dev/sdc:/dev/sdd2

The command can be divided into two parts

Ceph-deploy osd prepare ceph2:/dev/sdb:/dev/sdd1 ceph2:/dev/sdc:/dev/sdd2 ceph3:/dev/sdb:/dev/sdd1 ceph3:/dev/sdc:/dev/sdd2 ceph4:/dev/sdb:/dev/sdd1 ceph4:/dev/sdc:/dev/sdd2

Ceph-deploy osd activate ceph2:/dev/sdb1 ceph2:/devsdc1 ceph3:/dev/sdb1 ceph3:/dev/sdc1 ceph4:/dev/sdb1 ceph4:/dev/sdc1

By the end of the installation of this ceph

You can use ceph-s to check the health status of ceph

View osd

From the figure, you can see each node and the osd in the node.
