openstack学习笔记八 glance安装配置
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
# yum -y install openstack-glance.noarch
# openstack-db--init--service glance --password 123456 -rootpw 123456
# keystone user-create --name glance--pass 123456
# keystoneuser-role-add--user glance --tenant services --role admin
# keystoneservice-create--name glance --type image--description "glance jingxiang"

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
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
# ceph-deploynewh5
# ls
ceph.confceph-deploy-ceph.logceph.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
# ceph-deploy mon create-initial
# ls
ceph.bootstrap-mds.keyringceph.client.admin.keyringceph.mon.keyring
ceph.bootstrap-osd.keyringceph.conf
ceph.bootstrap-rgw.keyringceph.log 4 开始准备配置OSD
mkdir path1path2
# ceph-deploy osd prepareh5:/path1h6:/path2
# ceph-deploy osd activate h5:/path1h6:/path2 ##激活
Host h5 is now ready for osd use. 5 把key复制到各个节点上去
# ceph-deployadminh5 h6
# ceph health##健康性检查 6 生成元数据
# ceph-deploymdscreate h5
# rados lspools
# rados mkpool glance
# rados rmpool glanceglance --yes-i-really-really-mean-it##删除 glance配置成ceph的客户端
安装ceph
# ls
