镜像服务(概览)使用户可以发现，注册和检索虚拟机镜像。
它提供了REST API，使我们可以查询虚拟机镜像元数据并检索实际镜像。
我们可以将通过Image服务提供的虚拟机镜像存储在各个位置，从简单的文件系统到对象存储系统(如OpenStack对象存储)。
创建Glance数据库
使用数据库访问客户端以root用户身份连接到数据库服务器：
[root@controller ~]# mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or g. Your MariaDB connection id is 6 Server version: 10.1.20-MariaDB MariaDB Server Copyright (c) 2000, 2015, Oracle, MariaDB Corporation Ab and others. Type 'help;' or 'h' for help. Type 'c' to clear the current input statement. MariaDB [(none)]> CREATE DATABASE glance; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'redhat'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'redhat'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> exit Bye
说明：
这里的" redhat"是我的nova数据库的密码
创建一目了然的用户和角色
[root@controller ~]# openstack user create --domain default --password-prompt glance
User Password:
Repeat User Password:
+---------------------+----------------------------------+

| name | glance |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
将admin角色添加到glance用户和service项目中：
[root@controller ~]# openstack role add --project service --user glance admin
创建一目了然的服务实体
[root@controller ~]# openstack service create --name glance --description "OpenStack Image" image +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Image | | enabled | True | | id | 123bf6d523e948a2abcd4b571e8cbadd | | name | glance | | type | image | +-------------+----------------------------------+

安装glance软件包
[root@controller ~]# yum install openstack-glance -y
更新glance配置文件
更新/etc/glance/glance-api.conf文件并完成以下操作：
说明：
用上述步骤中分配的glance用户密码和glance数据库密码替换GLANCE_PASS和GLANCE_DBPASS
[root@controller ~]# openstack-config --set /etc/glance/glance-api.conf database connection mysql+pymysql://glance:GLANCE_DBPASS@controller/glance [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_uri http://controller:5000 [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_url http://controller:35357 [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken memcached_servers controller:11211 [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_type password [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_domain_name Default [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken user_domain_name Default [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_name service [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken username glance [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken password GLANCE_PASS [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf paste_deploy flavor keystone [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf glance_store stores file,http [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf glance_store default_store file [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf glance_store filesystem_store_datadir /var/lib/glance/images/

填充图像服务数据库

启用Glance API和Glance注册表服务
[root@controller ~]# systemctl enable openstack-glance-api.service openstack-glance-registry.service [root@controller ~]# systemctl start openstack-glance-api.service openstack-glance-registry.service
验证Glance API和Glance注册中心服务
使用CirrOS验证镜像服务的操作，CirrOS是一个小的Linux镜像，可测试OpenStack部署。
[root@controller ~]# source adminrc
下载cirros源图像
[root@controller ~]# wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img --2016-11-01 16:43:44-- http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img Resolving download.cirros-cloud.net (download.cirros-cloud.net)... 64.90.42.85, 2607:f298:6:a036::bd6:a72a Connecting to download.cirros-cloud.net (download.cirros-cloud.net)|64.90.42.85|:80... connected.

检查文件是否已下载
[root@controller ~]# ls -lh cirros-0.4.0-x86_64-disk.img -rw-r--r-- 1 root root 13M Nov 20 2016 cirros-0.4.0-x86_64-disk.img
使用QCOW2磁盘格式，裸容器格式和公共可见性将图像上传到图像服务，以便所有项目都可以访问它：
[root@controller ~]# openstack image create cirros --file ~/cirros-0.4.0-x86_64-disk.img --disk-format qcow2 --public +------------------+------------------------------------------------------+ | Field | Value | +------------------+------------------------------------------------------+ | checksum | 443b7623e27ecf03dc9e01ee93f67afe | | container_format | bare | | created_at | 2016-11-01T11:53:50Z | | disk_format | qcow2 | | file | /v2/images/169bc19c-e9c9-4de3-ade4-c9cc9a443162/file | | id | 169bc19c-e9c9-4de3-ade4-c9cc9a443162 | | min_disk | 0 | | min_ram | 0 | | name | cirros | | owner | 8bb9c0b1fa7947778a4f914ea0752cfc | | protected | False | | schema | /v2/schemas/image | | size | 12716032 | | status | active | | tags | | | updated_at | 2016-11-01T11:53:51Z | | virtual_size | None | | visibility | public | +------------------+------------------------------------------------------+
确认上传图片并验证属性：
[root@controller ~]# openstack image list +--------------------------------------+--------+--------+ | ID | Name | Status | +--------------------------------------+--------+--------+ | 169bc19c-e9c9-4de3-ade4-c9cc9a443162 | cirros | active | +--------------------------------------+--------+--------+
我们也可以使用(--copy-from)将图像从网上直接上传到扫视图像数据库。
[root@controller ~]# openstack image create "cirros-1" --file ~/cirros-0.4.0-x86_64-disk.img --disk-format qcow2 --public --copy-from http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img ERROR: --copy-from was given, which is an Image v1 option that is no longer supported in Image v2
说明：
仅OS_IMAGE_API_VERSION的V1版本支持参数--copy-from。
因此，我们需要手动更改此变量的API版本。
[root@controller ~]# cat adminrc export OS_PROJECT_DOMAIN_NAME=default export OS_USER_DOMAIN_NAME=default export OS_PROJECT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=redhat export OS_AUTH_URL=http://controller:35357/v3 export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2
[root@controller ~]# export OS_IMAGE_API_VERSION=1
接下来重新尝试上传
[root@controller ~]# openstack image create "cirros-1" --file ~/cirros-0.4.0-x86_64-disk.img --disk-format qcow2 --public --copy-from http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img +------------------+--------------------------------------+ | Field | Value | +------------------+--------------------------------------+ | checksum | None | | container_format | bare | | created_at | 2016-11-01T12:51:21.000000 | | deleted | False | | deleted_at | None | | disk_format | qcow2 | | id | b28add75-85ec-46a3-8b8b-3de77944ee26 | | is_public | True | | min_disk | 0 | | min_ram | 0 | | name | cirros-1 | | owner | None | | properties | | | protected | False | | size | 12716032 | | status | queued | | updated_at | 2016-11-01T12:51:21.000000 | | virtual_size | None | +------------------+--------------------------------------+
检查上传的图片列表
[root@controller ~]# openstack image list +--------------------------------------+----------+--------+ | ID | Name | Status | +--------------------------------------+----------+--------+ | 169bc19c-e9c9-4de3-ade4-c9cc9a443162 | cirros | active | | b28add75-85ec-46a3-8b8b-3de77944ee26 | cirros-1 | active | +--------------------------------------+----------+--------+
配置计算
OpenStack Compute与OpenStack Identity交互以进行身份验证；用于磁盘和服务器镜像的OpenStack镜像服务；和用于用户和管理界面的OpenStack仪表板。
图像访问受到项目和用户的限制；每个项目都限制配额(例如，实例数)。
OpenStack Compute可以在标准硬件上水平扩展，并下载镜像以启动实例。
创建计算数据库
使用数据库访问客户端以root用户身份连接到数据库服务器：
[root@controller ~]# mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or g.
