Openstack_O版(otaka)部署_镜像服务glance部署

安装和配置服务

1. 建库建用户

mysql -u root -p

CREATE DATABASE glance;

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '123456';

flush privileges;

2. keystone认证操作

上面提到过：所有后续项目的部署都统一放到一个租户service里，然后需要为每个项目建立用户，建管理员角色，建立关联

. admin-openrc # 修改环境变量获取token

openstack user create --domain default --password-prompt glance

+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | 135e691ebbb74fefb5086970eac74706 |
| enabled             | True                             |
| id                  | e8febba19a724bc7b27e5f485f43104b |
| name                | glance                           |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

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

建立服务实体

openstack service create --name glance --description "OpenStack Image" image

+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Image                  |
| enabled     | True                             |
| id          | c1334a6d30644f399acb9a40f6d7dac5 |
| name        | glance                           |
| type        | image                            |
+-------------+----------------------------------+

建端点

3. 安装软件

yum install openstack-glance -y

4. 初始化存放镜像的存储设备

# 此处我们暂时用本地存储，但是无论哪种存储，都应该在glance启动前就已经有了，否则glance启动时通过驱动程序检索不到存储设备，

# 即在glance启动后 新建的存储设备无法被glance识别到，需要重新启动glance才可以，因此我们将下面的步骤提到了最前面

# 新建目录

mkdir -p /var/lib/glance/images/

chown glance. /var/lib/glance/images/

5. 修改配置

vim /etc/glance/glance-api.conf

[database]

# 这里的数据库连接配置是用来初始化生成数据库表结构,不配置无法生成数据库表结构

# glance-api不配置database对创建vm无影响，对使用metada有影响

# 日志报错:ERROR glance.api.v2.metadef_namespaces

connection = mysql+pymysql://glance:123456@controller01/glance

[keystone_authtoken]

auth_url = http://controller01:5000

memcached_servers = controller01:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = glance

password = 123456

[paste_deploy]

flavor = keystone

[glance_store]

stores = file,http

default_store = file

filesystem_store_datadir = /var/lib/glance/images/ 

vim /etc/glance/glance-registry.conf

[database]

#这里的数据库配置是用来glance-registry检索镜像元数据

connection = mysql+pymysql://glance:123456@controller01/glance

6. 同步数据库

此处会报一些关于future的问题，自行忽略

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

7. 启动服务

systemctl enable openstack-glance-api.service openstack-glance-registry.service
systemctl start openstack-glance-api.service openstack-glance-registry.service

验证操作

. admin-openrc

wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

openstack image create "cirros" --file cirros-0.3.4-x86_64-disk.img --disk-format qcow2 --container-format bare --public
