目录
一、创建数据库
1、创建数据库：控制节点部署
①、授予数据库访问权限
②、刷新数据库
[root@controller ~]# mysql -u root -p
MariaDB [(none)]> create database glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY '123456';
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> quit2、获取管理员的权限访问OpenStack cli
[root@controller ~]# . admin-openrc.sh 3、创建服务凭据:
①、创建用户glance
密码："123456"
②、将角色添加到用户项目
[root@controller ~]# openstack user create --domain default --password-prompt glance
User Password:
Repeat User Password:

+---------------------+----------------------------------+
[root@controller ~]# openstack role add --project service --user glance admin4、创建服务实体：glance
[root@controller ~]# openstack service create --name glance \
--description "OpenStack Image" image

| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Image |

| id | ada0880b696a4979a7bd2d14f0b0de1e |
| name | glance |
| type | image |
+-------------+----------------------------------+5、创建镜像服务API端点
[root@controller ~]# openstack endpoint create --region RegionOne \
image public http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | bdc918c21b8d4774b9db7b74fbb496fa |

+--------------+----------------------------------+二、安装配置组件
1、安装软件包
2、修改配置文件/etc/glance/glance-api.conf
3、填充镜像服务数据库
[root@controller ~]# yum install openstack-glance -y
[root@controller ~]# vim /etc/glance/glance-api.conf
#配置数据库访问
[database]
connection = mysql+pymysql://glance:123456@controller/glance
#配置本地文件系统存储和图像文件的位置
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
#配置标识服务访问
[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = 123456
#配置标识服务访问
[paste_deploy]
flavor = keystone
[root@controller glance]# su -s /bin/sh -c "glance-manage db_sync" glance三、启动Glance服务
1、启动glance服务，并设置开机自启动
目录
四、验证是否完成安装
1、获取管理员对OpenStack cli的访问权限
[root@controller ~]# . admin-openrc.sh 2、下载源镜像
[root@controller ~]# wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
