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 and Identity service credentials including 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 Identity service credentials, complete these
steps:Create the glance user:$keystone user-create --name glance --pass GLANCE_PASS --email EMAIL_ADDRESS+----------+----------------------------------+
| Property | Value |

| email | glance@example.com |
| enabled | True |

| name | glance |
| username | glance |
+----------+----------------------------------+Replace GLANCE_PASS with a suitable
password and EMAIL_ADDRESS with
a suitable e-mail address.Link the glance user to the
service tenant and admin
role:$keystone user-role-add --user glance --tenant service --role adminThis command provides no output.Create the glance service:$keystone service-create --name glance --type image \

the system boots:#service openstack-glance-api start#service openstack-glance-registry start#chkconfig openstack-glance-api on#chkconfig openstack-glance-registry onBy default, the Ubuntu packages create an SQLite database.Because this configuration uses a SQL database server, you can
remove the SQLite database file:#rm -f /var/lib/glance/glance.sqlite
