镜像 安装过系统的虚拟硬盘
管理是用glance来完成。
镜像的状态：
active 镜像已经上传完成，并且是可用的
saving 正在被上传，还没有完成
killed 上传出错
queued 并没有真的上传完成，但是被标记有这个镜像
安装glance
在 keystone注册
glance所需要的账户
创建glance服务
指定glance服务的endpoint
安装

ceph 共享存储
安装epel仓库
rpm -vih http://mirrors.sohu.com/fedora-epel/7/x86_64/e/epel-release-7-2.noarch.rpm 添加yum ceph仓库 vim /etc/yum.repos.d/ceph.repo [ceph] name=Ceph noarch packages baseurl=http://mirrors.163.com/ceph/rpm-hammer/el7/x86_64/ enabled=1 gpgcheck=1 type=rpm-md gpgkey=http://mirrors.163.com/ceph/keys/release.asc 安装ceph-deploy,ceph（ceph所有节点都安装，ceph-deploy只需admin节点安装） yum -y update && yum -y install --release hammer ceph ceph-deploy
1 生成相关的MOD信息 监控服务器 h5
[root@h5 xx]# ceph-deploy new h5 [root@h5 xx]# ls ceph.conf ceph-deploy-ceph.log ceph.mon.keyring
2 要根据自己的情况修改配置文件ceph.conf
osd_pool_default_size = 2 ##几个节点组成，默认是3 osd_pool_defaults_min_size = 1 ##最小值是1
3 生成key 当客户端要链接到ceph服务器，需要用户名和密码
[root@h5 xx]# ceph-deploy mon create-initial [root@h5 myceph]# ls ceph.bootstrap-mds.keyring ceph.client.admin.keyring ceph.mon.keyring ceph.bootstrap-osd.keyring ceph.conf ceph.bootstrap-rgw.keyring ceph.log
4 开始准备配置OSD
mkdir path1 path2 [root@h5 xx]# ceph-deploy osd prepare h5:/path1 h6:/path2 [root@h5 xx]# ceph-deploy osd activate h5:/path1 h6:/path2 ##激活 [ceph_deploy.osd][DEBUG ] Host h5 is now ready for osd use.
5 把key复制到各个节点上去
[root@h5 ceph]# ceph-deploy admin h5 h6 [root@h5 ceph]# ceph health ##健康性检查
6 生成元数据
[root@h5 ceph]# ceph-deploy mds create h5 [root@h5 ceph]# rados lspools [root@h5 ceph]# rados mkpool glance [root@h5 ceph]# rados rmpool glance glance --yes-i-really-really-mean-it ##删除
glance配置成ceph的客户端
安装ceph
[root@h4 ceph(keystone_admin)]# ls rbdmap [root@h5 myceph]# ceph-deploy admin h4 [root@h4 ceph(keystone_admin)]# ls ceph.client.admin.keyring ceph.conf rbdmap tmp6BxOoY vim glance-api.conf [glance_store] default_store = rbd stores = rbd rbd_store_pool = glance rbd_store_user = admin rbd_store_ceph_conf = /etc/ceph/ceph.conf rbd_store_chunk_size = 8 systemctl restart openstack-glance-api.service openstack-glance-registry.service openstack-glance-scrubber.service -rw------- 1 root root 63 7月 21 16:43 ceph.client.admin.keyring setfacl -m u:glance:r-- ceph.client.admin.keyring ##设置权限 能读
