本篇文章是本系列的第三篇文章，将继续进行OpenStack镜像服务的安装
四、安装镜像服务
4.1 （控制节点）配置镜像数据库
- 连接数据库
# mysql -u root -pfuai123- 创建glance数据库并设置访问权限
MariaDB [(none)]> CREATE DATABASE glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY 'fuai123';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY 'fuai123';
4.2 （控制节点）创建glance认证相关信息
- 设置admin环境变量
# . admin-openrc- 创建glance用户
密码我设置的fuai123
# openstack user create --domain default --password-prompt glance
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | 0bf68fa1a87c4760859f9f34697a8753 |
| name | glance |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+- 将glance用户加入service项目，并设置admin角色
# openstack role add --project service --user glance admin- 创建镜像服务
# openstack service create --name glance \
--description "OpenStack Image" image
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+
| description | OpenStack Image |
| enabled | True |
| id | 520b45f9c795468ab50a5c7c363babef |
| name | glance |
| type | image |
+-------------+----------------------------------+- 创建镜像api端口
# openstack endpoint create --region RegionOne \
image public http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | ff8c65b2d96c4329a85954ed4ac13853 |
| interface | public |
| region | RegionOne |
| region_id | RegionOne |
| service_id | 520b45f9c795468ab50a5c7c363babef |
| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
+--------------+----------------------------------+
# openstack endpoint create --region RegionOne \
image internal http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | 5d930d23645541b3ad76c9bb29426519 |
| interface | internal |

| service_name | glance |
| service_type | image |
| url | http://controller:9292 |
+--------------+----------------------------------+
# openstack endpoint create --region RegionOne \
image admin http://controller:9292
+--------------+----------------------------------+
| Field | Value |
+--------------+----------------------------------+
| enabled | True |
| id | e0fc9759fb7b4d4790d225aaedcdcf31 |

+--------------+----------------------------------+4.3 （控制节点）安装软件包并配置配置文件
- 安装软件包
# yum install openstack-glance -y- 编辑/etc/glance/glance-api.conf文件并完成下面配置
[database]
connection = mysql+pymysql://glance:fuai123@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 = fuai123
...
[paste_deploy]
flavor = keystone
...
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
...- 编辑/etc/glance/glance-registry.conf文件，完成以下配置
[database]
connection = mysql+pymysql://glance:fuai123@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 = fuai123
...
[paste_deploy]
flavor = keystone
...
- 同步数据库
# su -s /bin/sh -c "glance-manage db_sync" glance4.4 （控制节点）设置服务的开机自启动，并启动服务
- 设置服务自启，并启动服务
# systemctl enable openstack-glance-api.service \
openstack-glance-registry.service
# systemctl start openstack-glance-api.service \
openstack-glance-registry.service4.5 （控制节点）验证操作
- 设置环境变量
# . admin-openrc- 下载镜像
# yum install wget -y
# wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img- 上传镜像
# openstack image create "cirros" \
--file cirros-0.3.5-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--public
