OpenStack—M Glance（镜像服务）

一、数据库配置

Controller节点

1.创建Glance数据库并授权

# mysql -uroot -p123456
MariaDB [(none)]> create database glance;
MariaDB [(none)]> grant all privileges on glance.* to 'glance'@'%' identified by '123456';
MariaDB [(none)]> grant all privileges on glance.* to 'glance'@'localhost' identified by '123456';
MariaDB [(none)]> exit

二、创建服务凭证和API端点

Controller节点

1）创建服务凭证

# . admin-openrc 

# openstack user create --domain default --password-prompt glance
User Password:123456
Repeat User Password:123456      （输入密码时是看不见的）

# openstack role add --project service --user glance admin
# openstack service create --name glance --description "OpenStack Image" image

2）创建镜像服务的API端点

# 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 internal http://controller:9292

三、安装并配置Glance

Controller节点

1）安装glance所需软件包

# yum install -y openstack-glance

2）配置glance所需组件
编辑/etc/glance/glance-api.conf文件

# vi /etc/glance/glance-api.conf
[database]
connection = mysql+pymysql://glance:123456@controller/glance

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = 123456

[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

# vi /etc/glance/glance-registry.conf
[database]
connection = mysql+pymysql://glance:123456@controller/glance

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = 123456

[paste_deploy]
flavor = keystone

3）同步数据库

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

4）启动glance服务，并设置开机自启

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

四、验证Glance服务

Controller节点

1）上传镜像文件

# openstack image create "cirros" --file cirros-0.3.4-x86_64-disk.img \
   --disk-format qcow2 --container-format bare –public

注：cirros-0.3.4-x86_64-disk.img文件在Mitaka.iso文件里，挂载后进入image目录可以看见

2）查看上传的镜像并验证属性

# openstack image list
# openstack image show cirros
