安装glance镜像服务

• 创建并设置glance的数据库

mysql -u root -p

MariaDB [(none)]> CREATE DATABASE glance;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
  IDENTIFIED BY 'xxxxxxx';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
  IDENTIFIED BY 'xxxxxxx';

• 创建glance镜像服务的keystone相关认证信息

  • 用户密码：glance:xxxxxxx

# 设置环境变量
. admin-openrc
# 创建glance用户
openstack user create --domain default --password-prompt glance
# 将glance用户加入service项目，并设置为amdin角色
openstack role add --project service --user glance admin
# 创建名为glance的服务
openstack service create --name glance \
  --description "OpenStack Image" image

• 创建镜像的api端口

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

yum install openstack-glance -y

• 配置api

vim /etc/glance/glance-api.conf

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