This article mainly introduces how to use ceph-deploy to deploy ceph commands, the article is very detailed, has a certain reference value, interested friends must read it!

1. Execute the useradd command on each node to add a user (such as ceph) with the password set to empty

two。 Execute the ssh-keygen command on the mon.0 node, and then execute ssh-copy-id to copy the ssh public key to each node. Modify the sshd config file to enable remote password-less login.

3.ceph-deploy install is executed on each node (essentially the installation Ceph packages,iso is already included, this step can be skipped)

4. Ceph-deploy new adds mon nodes and modifies ceph.conf

This command actually generates only the ceph.conf and ceph.mon.keyring files.

5. Ceph-deploy mon create-initial

6. Ceph-deploy osd zap / / format partition

7. Ceph-deploy osd prepare / / add osd

8. Ceph-deploy osd activate (create = prepare then activate)

9. Ceph-deploy admin

Copy ceph.conf and ceph.client.admin.keyring to / etc/ceph, and you can use ceph CLI instead of specifying monitor address and ceph.client.admin.keyring when executing commands later

So that each node can manage the cluster.

10.ceph-deploy mon create add mon Node

11. Ceph-deploy forgetkeys deletes the local keys

12. Ceph-deploy gatherkeys retrieves the keys from the moniter node to manage the node. (for administering the cluster and bootstrapping new nodes)

13. Ceph-deploy config pull gets ceph.conf from cluster

14.ceph-create-keys-id:

Generate / var/lib/ceph/bootstrap-mds/ceph.keyring

15. The configuration file is as follows:

Under the deploy directory:

Ceph.conf

Ceph.mon.keyring-> Cluster keying

Ceph.bootstrap-mds.keyring

Ceph.bootstrap-osd.keyring-> is used to create osd

Ceph.client.admin.keyring-> create administrator keyring, generate admin users, and add users to keyring. The keyring needs to be added to the ceph.mon,keyring

Releasse.asc

Ceph.log

/ var/lib:

/ var/lib/ceph/bootstrap-osd/ceph.keyring

/ var/lib/ceph/bootstrap-mds/ceph.keyring

/ etc:

/ etc/ceph/ceph.conf

/ etc/ceph/ceph.client.admin.keyring

/ root:

/ root/.cephconfig
