openstack对接ceph后端存储
- 对接glance后端存储
- 对接nova后端存储
- 对接cinder后端存储
openstack T版对接ceph 14版本做glance、nova、cinder后端存储，openstack集群和ceph集群均搭建完毕

创建cinder、glance、nova存储池
[root@storage01 ceph-cluster]# ceph osd pool create volumes 8
pool 'volumes' created
[root@storage01 ceph-cluster]# ceph osd pool create images 8
pool 'images' created
[root@storage01 ceph-cluster]# ceph osd pool create vms 8
pool 'vms' created
[root@storage01 ceph-cluster]# ceph osd lspools
4 volumes
5 images
6 vms
创建用户以及密钥
[root@storage01 ceph-cluster]# 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=vms,allow rx pool=images"
[client.cinder]key = AQDRE3tkDVGeFxAAPkGPKGlqh74pRl2dzIJXAw==
[root@storage01 ceph-cluster]# ceph auth get-or-create client.glance mon "allow r" osd "allow class-read object_prefix rbd_children,allow rwx pool=images"
[client.glance]key = AQDaE3tkKTQCIRAAwRQ/VeIjL4G5GjmsJIbTwg==
[root@storage01 ceph-cluster]#
openstack节点创建ceph目录，T版计算节点默认创建了
[root@controller ~]# mkdir /etc/ceph/
ceph导出密钥glance和cinder，并导入到opesntack
[root@storage01 ceph-cluster]# ceph auth get client.glance -o ceph.client.glance.keyring
exported keyring for client.glance
[root@storage01 ceph-cluster]# ceph auth get client.cinder -o ceph.client.cinder.keyring
exported keyring for client.cinder
[root@storage01 ceph-cluster]#
[root@storage01 ceph-cluster]# scp ceph.client.glance.keyring root@192.168.200.10:/etc/ceph/
[root@storage01 ceph-cluster]# scp ceph.client.glance.keyring root@192.168.200.20:/etc/ceph/
[root@storage01 ceph-cluster]# scp ceph.client.cinder.keyring root@192.168.200.10:/etc/ceph/
[root@storage01 ceph-cluster]# scp ceph.client.cinder.keyring root@192.168.200.20:/etc/ceph/
拷贝认证文件到集群
[root@storage01 ceph-cluster]# scp ceph.conf root@192.168.200.20:/etc/ceph/
[root@storage01 ceph-cluster]# scp ceph.conf root@192.168.200.10:/etc/ceph/
计算节点添加libvirt密钥
[root@compute ~]# cd /etc/ceph/
[root@compute ceph]# UUID=$(uuidgen)
cat >> secret.xml << EOF
<secret ephemeral='no' private='no'><uuid>$UUID</uuid><usage type='ceph'><name>client.cinder secret</name></usage>
</secret>
EOF
[root@compute ceph]# virsh secret-define --file secret.xml

安装客户端工具，需计算节点添加ceph的yum源
[root@controller ~]# yum install -y ceph-common
[root@compute ~]# yum install -y ceph-common
对接glance后端存储
更改配置文件属性
[root@controller ~]# chown glance.glance /etc/ceph/ceph.client.glance.keyring
[root@controller ~]# vi /etc/glance/glance-api.conf
[glance_store]
#stores = file,http
#default_store = file
#filesystem_store_datadir = /var/lib/glance/images/
stores = rbd
default_store = rbd
show_image_direct_url = True
rbd_store_pool = images
rbd_store_user = glance
rbd_store_ceph_conf = /etc/ceph/ceph.conf
rbd_store_chunk_size = 8
重启服务
