Glance是OpenStack的镜像服务，负责用户虚拟机镜像的发现，注册和获取。Glance部署在Controller节点上。

创建数据库和用户(注意替换GLANCE_DBPASS)

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

退出mysql，加载环境变量(admin-openrc内容见上一文章)

. admin-openrc

创建Glance服务相关的鉴权信息

openstack user create --domain default --password-prompt glance
openstack role add --project service --user glance admin

创建Glance的服务对象和api节点

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 admin http://controller:9292

安装Glance

sudo apt-get install glance

修改配置文件

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

修改database(注意替换GLANCE_DBPASS)

[database]
#...
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance

修改keystone_authtoken和paste_deploy(注意替换GLANCE_DBPASS)

[keystone_authtoken]
# ...
www_authenticate_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 = GLANCE_PASS

[paste_deploy]
# ...
flavor = keystone

修改glance_store

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

初始化数据库

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

启动服务

sudo systemctl restart glance-api.service
sudo systemctl enable glance-api.service

测试部署是否成功

# 加载环境变量
. admin-openrc

# 下载镜像
wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img

# 上传镜像
glance image-create --name "cirros" \
  --file cirros-0.4.0-x86_64-disk.img \
  --disk-format qcow2 --container-format bare \
  --visibility=public

#查询镜像
glance image-list
