 +</code> 
 + 
 +=== 確認 === 
 +

 + 
 + 
 +==== デプロイ ==== 
 + 
 +  # ceph orch apply -i ceph_cluster_conf.yaml 
 + 
 +下記で見ているとだんだんcephが構築されていってるのが見える 
 + 
 +  watch ceph -s 
 + 
 + 
 +=== cephadmでceph.confを持ってくる場合 === 
 + 
 +  cephadm shell cat /etc/ceph/ceph.conf > /etc/ceph/ceph.conf 
 + 
 + 
 +===== 2 openstack用設定 ===== 
 + 
 +==== openstack用のpoolを用意しておく ==== 
 + 
 +<code> 
 +# ceph osd pool create volumes 
 +# ceph osd pool create images 
 +# ceph osd pool create backups 
 +# ceph osd pool create vms 
 + 
 +# rbd pool init volumes 
 +# rbd pool init images 
 +# rbd pool init backups 
 +# rbd pool init vms 
 +</code> 
 + 
 +==== openstack用のkeyingを用意しておく ==== 
 + 
 +<code> 
 +# ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=images' -o /etc/ceph/ceph.client.glance.keyring 
 +# ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rwx pool=images' -o /etc/ceph/ceph.client.cinder.keyring 
 +# ceph auth get-or-create client.nova mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=vms, allow rx pool=images' -o /etc/ceph/ceph.client.nova.keyring 
 +# ceph auth get-or-create client.cinder-backup mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=backups' -o /etc/ceph/ceph.client.cinder-backup.keyring  
 +</code> 
 + 
 +==== OpenStack設定変更 ==== 
 + 
 +このrbd-1ってのが、cephになります。 
 + 
 +<code> 
 +# vi /etc/kolla/globals.yml 
 + 
 +# Cinder 
 +enable_cinder: "yes" 
 +enable_cinder_backend_nfs: "yes" 
 +skip_cinder_backend_check: True 
 +cinder_enabled_backends: 
 +  - name: rbd-1 
 +  - name: linstor-drbd 
 +  - name: nfs-1 
 +   
 +# Cinder-Backup 
 +enable_cinder_backup: "yes" 
 +cinder_backup_driver: "nfs" 
 +cinder_backup_share: "192.168.0.101:/nfs" 
 + 
 +## ceph 
 +glance_backend_ceph: "yes" 
 +cinder_backend_ceph: "yes" 
 +</code> 
 + 
 +==== ceph.conf修正 ==== 
 +ansibleを流すときに、ceph.confにタブがあると失敗するのでタブを削除 
 + 
 +  sed -i 's/\t//'g /etc/ceph/ceph.conf 
 + 
 + 
 +==== ceph用のファイル用意 ==== 
 + 
 +<code> 
 +mkdir /etc/kolla/config 
 +mkdir /etc/kolla/config/nova 
 +mkdir /etc/kolla/config/glance 
 +mkdir -p /etc/kolla/config/cinder/cinder-volume 
 +mkdir /etc/kolla/config/cinder/cinder-backup 
 + 
 +cp /etc/ceph/ceph.conf /etc/kolla/config/cinder/ 
 +cp /etc/ceph/ceph.conf /etc/kolla/config/nova/ 
 +cp /etc/ceph/ceph.conf /etc/kolla/config/glance/ 
 +cp /etc/ceph/ceph.client.glance.keyring /etc/kolla/config/glance/

 +cp /etc/ceph/ceph.client.cinder-backup.keyring /etc/kolla/config/cinder/cinder-backup/
