本文详细介绍如何在控制节点上安装和配置OpenStack的Glance镜像服务，包括数据库设置、用户权限分配、API endpoints创建及配置文件调整等内容。

镜像服务image service（glance）的安装还是在控制节点上进行：

1、前提条件，数据库为glance创建库和账户密码来连接数据库

# mysql -u root -p
MariaDB [(none)]> CREATE DATABASE glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'glance';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%'IDENTIFIED BY 'glance';

2、在为glance在keystone上创建用户项目等时，需要先连接keystone，这里使用keystone的admin账号来登录

# source  admin-openrc

然后在创建glance用户：

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

输入密码：glance

将admin角色添加到glance用户和service项目中：

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

为glance创建服务实体：

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

为镜像服务创建API endpoints：

# openstack endpoint create --region RegionOne image public http://192.168.101.10:9292
# openstack endpoint create --region RegionOne image internal http://192.168.101.10:9292
# openstack endpoint create --region RegionOne image admin http://192.168.101.10:9292

安装和配置glance：

# yum install openstack-glance

修改配置文件：/etc/glance/glance-api.conf，在[database]部分：

connection = mysql+pymysql://glance:glance@192.168.101.10/glance

在[keystone_authtoken]和[paste_deploy]分别做如下设置：

[keystone_authtoken]
auth_uri = http://192.168.101.10:5000
auth_url = http://192.168.101.10:35357
memcached_servers = 192.168.101.10:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = glance

[paste_deploy]
flavor = keystone

在[glance_store]部分设置一个本地文件系统用来存储本地镜像：

[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/

修改配置文件：/etc/glance/glance-registry.conf，在[database]配置数据库的连接：

connection = mysql+pymysql://glance:glance@192.168.101.10/glance

在[keystone_authtoken]和[paste_deploy]配置如下内容：

[keystone_authtoken]
auth_uri = http://192.168.101.10:5000
auth_url = http://192.168.101.10:35357
memcached_servers = 192.168.101.10:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = glance

[paste_deploy]
flavor = keystone

向glance库导入填充数据：

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

　　Ignore any deprecation messages in this output.

验证glance是否有table？

最后开启glance服务：

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

校验glance：校验image service是否安装成功？

# source admin-openrc
# wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
# openstack image create "cirros" --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public

上传镜像到镜像服务上，使用格式qcow2磁盘格式，权限为public，所有的项目都能访问它

# openstack image list    查看镜像列表

至此glance的image service组件安装成功

贴出glance两个配置文件的配置：

1、/etc/glance/glance-api.conf

[root@node1 ~]# egrep -v "^$|^#" /etc/glance/glance-api.conf 
[DEFAULT]
[cors]
[database]
connection = mysql+pymysql://glance:glance@192.168.101.10/glance
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
[image_format]
[keystone_authtoken]
auth_uri = http://192.168.101.10:5000
auth_url = http://192.168.101.10:35357
memcached_servers = 192.168.101.10:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = glance
[matchmaker_redis]
[oslo_concurrency]
[oslo_messaging_amqp]
[oslo_messaging_kafka]
[oslo_messaging_notifications]
[oslo_messaging_rabbit]
[oslo_messaging_zmq]
[oslo_middleware]
[oslo_policy]
[paste_deploy]
flavor = keystone
[profiler]
[store_type_location_strategy]
[task]
[taskflow_executor]

2、配置文件/etc/glance/glance-registry.conf

[root@node1 ~]# egrep -v "^$|^#" /etc/glance/glance-registry.conf 
[DEFAULT]
[database]
connection = mysql+pymysql://glance:glance@192.168.101.10/glance
[keystone_authtoken]
auth_uri = http://192.168.101.10:5000
auth_url = http://192.168.101.10:35357
memcached_servers = 192.168.101.10:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = glance
[matchmaker_redis]
[oslo_messaging_amqp]
