1.安装前准备
1.1 创建数据库及用户
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';
#GLANCE_DBPASS需要替换成自己想设置的
1.2 在identity service中创建glance 用户
1.导入环境变量
. admin-openrc
2.创建glance用户
openstack user create --domain default --password-prompt glance
3.设置glance用户规则
openstack role add --project service --user glance admin
4.创建glance服务条目
openstack service create --name glance --description "OpenStack Image" image
1.3 创建image服务的API访问点
root@ubuntu-ControllerNode:/home/ubuntu# openstack endpoint create --region RegionOne image public http://controller:9292

2.安装与配置
2.1.安装glance
apt install glance
2.2.配置/etc/glance/glance-api.conf
需要修改如下几个位置，GLANCE_DBPASS和GLANCE_PASS需要替换成自己设置的：
[database]
# ...
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
[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
[glance_store]
# ...
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
2.3.配置 /etc/glance/glance-registry.conf
修改如下内容，GLANCE_DBPASS和GLANCE_PASS需要替换成自己设置的：
[database]
# ...
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glancea
[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
2.4.迁移Image service的数据库
su -s /bin/sh -c "glance-manage db_sync" glance
2.5 重启Image services
service glance-registry restart
service glance-api restart
3.检测安装成果
1.导入环境变量
. admin-openrc
2.下载一个网上现场的镜像用来测试
wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
3.将镜像传给Image service，使用 QCOW2 的硬盘格式，不创建容器，设置权限为public
openstack image create "cirros" \
--file cirros-0.4.0-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--public

4.查看镜像是否上传成功
root@ubuntu-ControllerNode:/home/ubuntu# openstack image list
+--------------------------------------+--------+--------+
