一、建立glance数据库并且给权限设置第三方登录
mysql -uroot -p0330
CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO ‘glance’@’localhost’ \ IDENTIFIED BY ‘GLANCE_DBPASS’;
GRANT ALL PRIVILEGES ON glance.* TO ‘glance’@’%’ \ IDENTIFIED BY ‘GLANCE_DBPASS’;
二、部署glance
①宣告环境变量
source openrc或 . openrc
②创建glance用户
openstack user create –domain default –password=glance glance
③将项目service中的用户glance设置为admin角色
openstack role add –project service –user glance admin
④创建glance服务
openstack service create –name glance \ –description “OpenStack Image” image
⑤创建服务端点（RegionOne是一个域）
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
三、安装glance镜像服务，并编辑配置文件
①安装
yum install openstack-glance
②先复制在编辑配置文件
cp /etc/glance/glance-api.conf /etc/glance/glance-api.conf.bak
cp /etc/glance/glance-registry.conf /etc/glance/glance-registry.conf.bak
[DEFAULT][cors]
[cors.subdomain][database] #数据库连接方式
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance[glance_store] #镜像存储位置
stores = file,http #保存方式：文件，http类型
default_store = file #默认以文件进行存储
filesystem_store_datadir = /var/lib/glance/images/ #文件系统目录[image_format][keystone_authtoken] #keystone验证方式
auth_uri = http://controller:5000 #私有服务端点
auth_url = http://controller:35357 #管理服务端点
memcached_servers = controller: #缓存镜像的方式memcache
auth_type = password #认证类型：密码
project_domain_name = default #项目处在default域中
user_domain_name = default #user处在default域中
project_name = service #项目名称
username = glance #用户名称
password = glance #密码[matchmaker_redis][oslo_concurrency][oslo_messaging_amqp][oslo_messaging_kafka][oslo_messaging_notifications][oslo_messaging_rabbit][oslo_messaging_zmq][oslo_middleware][oslo_policy][paste_deploy]
flavor = keystone #flavor认证的模板方式[profiler][store_type_location_strategy][task][taskflow_executor]
vim /etc/glance/glance-api.conf
[DEFAULT][database]
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = glance[matchmaker_redis][oslo_messaging_amqp][oslo_messaging_kafka][oslo_messaging_notifications][oslo_messaging_rabbit][oslo_messaging_zmq][oslo_policy][paste_deploy]
flavor = keystone[profiler]
vim /etc/glance/glance-registry.conf
③同步数据库
su -s /bin/sh -c “glance-manage db_sync” glance
④重启并设置开机自启
systemctl enable openstack-glance-api.service openstack-glance-registry.service
systemctl start openstack-glance-api.service openstack-glance-registry.service
四、上传镜像
①上传镜像
cirros-0.3.5-x86_64-disk.img
source openrc
openstack image create “cirros” –file cirros-0.3.5-x86_64-disk.img –disk-format qcow2 –container-format bare –public
②查看镜像列表（镜像保存在/var/lib/glance/images）
opentack image list或glance image-list
【补充】
第三方进入数据库
1.必须安装mariadb客户端
2.登录的用户必须可以第三方登录
mysql -h ip -ukeystone -pkeystone
