　　Installing OpenStack Image Service
　　vagrant ssh controller
　　sudo apt-get update
sudo apt-get -y install glance
　　sudo apt-get update
sudo apt-get -y install glance-client
　　Using an alternative release
　　sudo apt-get update
sudo apt-get -y install python-software-properties
　　sudo add-apt-repository ppa:openstack-ubuntu-testing/havana-trunk-testing
　　Configuring OpenStack Image Service with MySQL
　　vagrant ssh controller
　　1. create the glance database
　　MYSQL_ROOT_PASSWORD=openstack
mysql -uroot -p$MYSQL_ROOT_PASSWORD -e 'CREATE DATABASE glance;'
　　2. create a glance user
　　MYSQL_GLANCE_PASSWORD=openstack
mysql -uroot -p${MYSQL_ROOT_PASSWORD} -e "GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '${MYSQL_GLANCE_PASSWORD}';"
mysql -uroot -p${MYSQL_ROOT_PASSWORD} -e "GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '${MYSQL_GLANCE_PASSWORD}';"
　　3. configure the OpenStack Image Service to use the database
　　sudo sed -i "s,^sql_connection.*,sql_connection = mysql://glance:${MYSQL_DB_PASSWORD}@172.16.0.200/glance," /etc/glance/glance-{registry,api}.conf
　　change the sql_connections line to match the database credentials.
　　4. restart the glance-registry service
　　sudo stop glance-registry
sudo start glance-registry
　　5. restart the glance-api service
　　sudo stop glance-api
sudo start glance-api
　　6. glance database is versioned controlled under Ubuntu 12.04 to allow upgrade and downgrade of service.
　　glance-manage version_control 0
　　7. sync the database to ensure the correct table structure is present.
　　sudo glance-manage db_sync
　　Configuring OpenStack Image Service with OpenStack Identity Service
　　vagrant ssh controller
　　1. edit the /etc/glance/glance-api-paste.ini file and configure the [filter:authtoken] section
　　[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_
token:filter_factory
admin_tenant_name = service
admin_user = glance
admin_password = glance
　　2. configure the /etc/glance/glance-api.conf file, to tell OpenStack Image Service to utilize OpenStack Identity Service
　　[keystone_authtoken]
auth_host = 172.16.0.200
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = glance
admin_password = glance
　　[paste_deploy]
config_file = /etc/glance/glance-api-paste.ini
flavor = keystone
　　3. edit the /etc/glance/glance-registry-paste.ini file and configure the [filter:authtoken] section
　　[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_
token:filter_factory
admin_tenant_name = service
admin_user = glance
admin_password = glance
　　4. configure the /etc/glance/glance-registry.conf file, to tell OpenStack Image Service to utilize OpenStack Identity Service
　　[keystone_authtoken]
auth_host = 172.16.0.200
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = glance
admin_password = glance
　　[paste_deploy]
config_file = /etc/glance/glance-registry-paste.ini
flavor = keystone
　　5. restart the two OpenStack Image Service processes
　　sudo restart glance-api
sudo restart glance-registry
　　Managing images with OpenStack Image Service
　　sudo apt-get update
sudo apt-get -y install glance-client
　　export OS_TENANT_NAME=cookbook
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=http://172.16.0.1:5000/v2.0/
export OS_NO_CACHE=1
　　uploading Ubuntu images
　　1. download an Ubuntu cloud image
　　wget http://uec-images.ubuntu.com/precise/current/precise-server-cloudimg-amd64-disk1.img
　　2. upload the cloud image
　　glance image-create --name='Ubuntu 12.04 x86_64 Server' --disk-format=qcow2 --container-format=bare --public < precise-server-clouding-amd64-disk1.img
　　listing images
　　glance image-list
　　viewing image details
　　glance image-show IMAGE-ID
glance image-show 794dca52-5fcd-4216-ac8e-7655cdc88852
　　deleting images
　　glance image-delete IMAGE-ID
　　making private images public
　　When uploading an image, they get entered into OpenStack Image Service as private by default.
　　1. list and view the image
　　glance image-show IMAGE-ID
　　2. convert to a public image
　　glance image-update IMAGE-ID --is-public True
　　3. issue a public glance listing
　　glance image-show IMAGE-ID
　　Registering a remotely stored image
　　sudo apt-get update
sudo apt-get -y install glance-client
　　export OS_TENANT_NAME=cookbook
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=http://172.16.0.200:5000/v2.0/
export OS_NO_CACHE=1
　　1. register a remote virtual image into the environment
　　glance image-create --name='Ubuntu 12.04 x86_64 Server' --disk-format=qcow2 --container-format=bare --public --locatin http://webserver/precise-server-clouding-amd64-disk1.img
