cephx 认证：对于不知道这个权限赋予的可以看下以前我写的cephx,
1，创建ceph.glance，ceph.cinder，ceph.backup用户密钥文件

1，拷贝glance,和cinder 密钥还有集群认证配置文件至controller01控制节点 前置所有openstack 节点创建/etc/ceph/ 目录
root@node1:/etc/ceph# scp ceph.client.cinder.keyring controller01.org:/etc/ceph/

root@controller01:/etc/ceph# ls

2，拷贝cinder 和backup密钥还有集群认证配置文件至computer01,computer02计算节点
computer01

计算节点添加libvirt密钥

所有openstack 节点安装ceph客户端：
使其能调用ceph 存储
apt install ceph-common -y配置glance用ceph做为后端存储
更改cephx文件权限为glance
root@controller01:/etc/ceph# chown glance:glance ceph.client.glance.keyring 修改配置文件使其调用ceph中的glance 池
root@controller01:/etc/glance# vi glance-api.conf
[glance_store]
stores = rbd,file,http
default_store = rbd
rbd_store_pool = glance
rbd_store_user = glance

rbd_store_chunk_size = 8
#stores = file,http
#default_store = file
#filesystem_store_datadir = /var/lib/glance/images/
重启glance-api服务：查看日志是否报错
root@controller01:/etc/glance# service glance-api restart
root@controller01:/etc/glance# tail -f /var/log/glance/glance-api.log上传镜像测试：
