Total PGs = (Total_number_of_OSD * 100) /max_replication_count）
1、 Create pool for OpenStack
pg=256 ceph osd pool create volumes $pg #disk_pool ceph osd pool create images $pg #image_pool ceph osd pool create vms $pg #host_pool ceph osd pool create backups $pg #backup_pool
2、 setup ceph client authentication
ceph auth get-or-create client.cinder mon‘allow r‘ osd ‘allow class-read object_prefix rbd_children, allow rwxpool=volumes, allow rwx pool=vms, allow rx pool=images‘ ceph auth get-or-create client.glance mon‘allow r‘ osd ‘allow class-read object_prefix rbd_children, allow rwxpool=images‘ ceph auth get-or-createclient.cinder-backup mon ‘allow r‘ osd ‘allow class-read object_prefixrbd_children, allow rwx pool=backups‘
3、Add the keyringsfor client.cinder, client.glance, and client.cinder-backup to the appropriatenodes and change their ownership
ceph auth get-or-create client.glance | ssh{your-glance-api-server} sudo tee /etc/ceph/ceph.client.glance.keyring
ssh {your-glance-api-server} sudo chownglance:glance /etc/ceph/ceph.client.glance.keyring
ceph auth get-or-create client.cinder | ssh{your-volume-server} sudo tee /etc/ceph/ceph.client.cinder.keyring
ssh {your-cinder-volume-server} sudo chowncinder:cinder /etc/ceph/ceph.client.cinder.keyring
4、 Nodes running nova-compute need the keyring file for thenova-compute process
ceph auth get-or-create client.cinder | ssh{your-nova-compute-server} sudo tee /etc/ceph/ceph.client.cinder.keyring
5、 Create a temporary copy of the secret key on the nodes runningnova-compute:
ceph auth get-key client.cinder > client.cinder.key
ceph auth get-key client.cinder | ssh{your-compute-node} tee client.cinder.key
uuidgen
4f859b95-406e-49f6-9ff8-d6e04f7ba1ef
cat > secret.xml <<EOF
<secret ephemeral=‘no‘ private=‘no‘>
<uuid>4f859b95-406e-49f6-9ff8-d6e04f7ba1ef</uuid>
<usage type=‘ceph‘>
<name>client.cinder secret</name>
</usage>
</secret>
EOF
sudo virsh secret-define --file secret.xml
sudo virsh secret-set-value --secret4f859b95-406e-49f6-9ff8-d6e04f7ba1ef --base64 $(cat client.cinder.key)&& rm client.cinder.key secret.xml
6、 Configuring Glance
vi /etc/glance/glance-api.conf [DEFAULT] ... default_store=rbd rbd_store_user=glance rbd_store_pool=images show_image_direct_url=True ...
7、 Configuring Cinder
vi /etc/cinder/cinder.conf [DEFAULT] ... volume_driver=cinder.volume.drivers.rbd.RBDDriver rbd_pool=volumes rbd_ceph_conf=/etc/ceph/ceph.conf rbd_flatten_volume_from_snapshot=false rbd_max_clone_depth=5 glance_api_version=2 rbd_user=cinder rbd_secret_uuid=4f859b95-406e-49f6-9ff8-d6e04f7ba1ef
8、 Configuring Cinder Backup
vi /etc/cinder/cinder.conf [DEFAULT] ... backup_driver=cinder.backup.drivers.ceph backup_ceph_conf=/etc/ceph/ceph.conf backup_ceph_user=cinder-backup backup_ceph_chunk_size=134217728 backup_ceph_pool=backups backup_ceph_stripe_unit=0 backup_ceph_stripe_count=0 restore_discard_excess_bytes=true
9、 Configuring Nova
vi /etc/nova/nova.conf [DEFAULT] ... libvirt_images_type=rbd libvirt_images_rbd_pool=vms libvirt_images_rbd_ceph_conf=/etc/ceph/ceph.conf rbd_user=cinder rbd_secret_uuid=9c9ee670-dd2c-4f44-9254-7b52a63caa9a libvirt_inject_password=false libvirt_inject_key=false libvirt_inject_partition=-2 libvirt_live_migration_flag="VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE,VIR_MIGRATE_PERSIST_DEST"
10、 Restart OpenStack
service openstack-glance-api restart service openstack-nova-compute restart service openstack-cinder-volume restart
10、Test
