安装glance镜像服务：

官方文档：https://docs.openstack.org/keystone/queens/install/keystone-install-rdo.html

1. 创建glance数据库，创建glance用户，并授权

mysql -uroot -p000000

CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '000000';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '000000';

2. 创建glance用户并赋予admin角色

获得 admin 凭证来获取只有管理员能执行的命令的访问权限：
source admin-openrc
openstack user create --domain default --password-prompt glance

[root@controller ~]# openstack user create --domain default --password-prompt glance
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | c7dd30904a9c4466898f0f512036d3d2 |
| name                | glance                           |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

openstack role add --project service --user glance admin

3. 创建glance服务，并创建endpoint（public，internal，admin）

每个glance服务都有自己的endpoint（public，internal，admin这三种）
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 internal http://controller:9292

[root@controller ~]# openstack service create --name glance --description "OpenStack Image" image
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Image                  |

+--------------+----------------------------------+

| url          | http://controller:9292           |
+--------------+----------------------------------+

4. 安装包：openstack-glance

yum install `openstack-glance -y`

5. 编辑/etc/glance/glance-api.conf文件

vim `/etc/glance/glance-api.conf`

[database]
     connection = mysql+pymysql://glance:000000@controller/glance
[keystone_authtoken]
     auth_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 = 000000
[paste_deploy]
     flavor = keystone
[glance_store]
     stores = file,http
     default_store = file
     filesystem_store_datadir = /var/lib/glance/images/

6. 编辑/etc/glance/glance-registry.conf文件

vim /etc/glance/glance-registry.conf

[database]
     connection = mysql+pymysql://glance:000000@controller/glance
[keystone_authtoken]
     auth_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 = 000000
[paste_deploy]
     flavor = keystone

7. 同步数据库

su -s /bin/sh -c "glance-manage db_sync" glance

8. 启动glance-api和glance-registry服务

systemctl enable openstack-glance-api.service \<br /> openstack-glance-registry.service
systemctl start openstack-glance-api.service \<br /> openstack-glance-registry.service

查看运行状态：

[root@controller ~]# systemctl status openstack-glance-api.service openstack-glance-registry.service

9. 下载一个基础镜像cirror

10. 上传镜像

openstack image create "cirros" \
--file cirros-0.3.5-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--public

[root@controller ~]# openstack image create "cirros" \

+------------------+------------------------------------------------------+

qcow2:指的是磁盘格式
-0.3.5-x86_64-disk:指的是版本号

11. 查看镜像

openstack image list

[root@controller ~]# openstack image list
+--------------------------------------+--------+--------+
| ID                                   | Name   | Status |
+--------------------------------------+--------+--------+
| 6d4ba40e-97eb-47b8-a855-4e0c114cdb2c | cirros | active |
+--------------------------------------+--------+--------+

这个镜像是我们以后创建虚拟机时需要使用的，和iso镜像不同

[OpenStack]六、Glance镜像服务部署

安装glance镜像服务：

1. 创建glance数据库，创建glance用户，并授权

2. 创建glance用户并赋予admin角色

3. 创建glance服务，并创建endpoint（public，internal，admin）

4. 安装包：openstack-glance

5. 编辑/etc/glance/glance-api.conf文件

6. 编辑/etc/glance/glance-registry.conf文件

7. 同步数据库

8. 启动glance-api和glance-registry服务

9. 下载一个基础镜像cirror

10. 上传镜像

11. 查看镜像
