Install and configureThis section describes how to install and configure the Image Service,
code-named glance, on the controller node. For simplicity, this
configuration stores images on the local file system.This section assumes proper installation, configuration, and
operation of the Identity service as described in
and
.To configure prerequisitesBefore you install and configure the Image Service, you must
create a database, service credentials, and API endpoints.To create the database, complete these steps:Use the database access client to connect to the database
server as the root user:$mysql -u root -pCreate the glance database:CREATE DATABASE glance;Grant proper access to the glance
database:GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY 'GLANCE_DBPASS';GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY 'GLANCE_DBPASS';Replace GLANCE_DBPASS with a suitable
password.Exit the database access client.Source the admin credentials to gain access to
admin-only CLI commands:$source admin-openrc.shTo create the service credentials, complete these steps:Create the glance user:$openstack user create --password-prompt glanceUser Password:

+--------------+----------------------------------+To install and configure the Image Service componentsDefault configuration files vary by distribution. You might need
to add these sections and options rather than modifying existing
sections and options. Also, an ellipsis (...) in the configuration
snippets indicates potential default configuration options that you
should retain.Install the packages:#apt-get install glance python-glanceclient#yum install openstack-glance python-glanceclient#zypper install openstack-glance python-glanceclientEdit the /etc/glance/glance-api.conf
file and complete the following actions:In the [database] section, configure
