Total PGs = (Total_number_of_OSD * 100) /max_replication_count）
1、 Create pool for OpenStack

pg=256ceph 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
|
1
|
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:

EOFsudo virsh secret-define --file secret.xml
sudo virsh secret-set-value --secret e05983be-9251-44cb-9738-198bf9ec2d7e --base64 $(cat client.cinder.key)&& rm client.cinder.key secret.xml
