本地文件系统版本请参照：
openstack搭建之镜像服务glance的安装(四)<本地文件系统版本> - 运维术 (cnbugs.com)
以下所有操作均在controller节点完成
认证服务创建
创建glance数据库并配置权限
mysql -uroot -p000000
create database glance;
grant all privileges on glance.* to 'glance'@'%' identified by '000000';
grant all privileges on glance.* to 'glance'@'localhost' identified by '000000';
exit
创建glance服务的认证
source admin-openrc创建用户
openstack user create --domain default --password-prompt glance创建角色
openstack role add --project service --user glance admin创建service entity和api endpoints：
openstack service create --name glance --description "OpenStack Image" image
openstack endpoint create --region RegionOne image public http://controller:9292
openstack endpoint create --region RegionOne image internal http://controller:9292
openstack endpoint create --region RegionOne image admin http://controller:9292安装glance服务
yum install -y openstack-glance ceph-common配置glance服务

EOF复制ceph集群配置文件
从ceph1复制集群配置文件/etc/ceph/ceph.conf到/etc/glance/
scp /etc/ceph/ceph.conf root@10.168.1.103:/etc/glance/ceph.conf初始化数据库
su -s /bin/sh -c "glance-manage db_sync" glance在ceph1节点获得ceph密钥
ceph auth get-or-create client.glance mon "allow r" osd 'allow class-read object_prefix rbd_children,allow rwx pool=images'
将获得的密钥保存
cat>/etc/glance/ceph.client.glance.keyring<<EOF

EOF启动glance服务并设开机启动
systemctl enable openstack-glance-api.service
systemctl start openstack-glance-api.service查看服务状态
systemctl status openstack-glance-api.service
至此，glance服务告一段落。
