Glance Configuration
  Glance uses SQLite by default. MySQL and PostgreSQL can also be configured to work with Glance.
  Open /etc/glance/glance-api-paste.ini and at the end of the file, edit the following lines:

admin_tenant_name = %SERVICE_TENANT_NAME%
admin_user = %SERVICE_USER%
admin_password = %SERVICE_PASSWORD%

  These values have to be modified as per the configurations made earlier. The admin_tenant_name will be 'service', admin_user will be 'glance' and admin_password is 'glance'.
  After editing, the lines should be as follows:

admin_tenant_name = service
admin_user = glance
admin_password = glance

  Now open /etc/glance/glance-registry-paste.ini and make similar changes at the end of the file.
  Open the file /etc/glance/glance-registry.conf and edit the line which contains the option "sql_connection =" to this:

sql_connection = mysql://glancedbadmin:glancesecret@192.168.26.128/glance
  In order to tell glance to use keystone for authentication, add the following lines at the end of the file.


flavor = keystone

  Open /etc/glance/glance-api.conf and add the following lines at the end of the document.


flavor = keystone

  Create glance schema in the MySQL database.:

sudo glance-manage version_control 0
sudo glance-manage db_sync

  Restart glance-api and glance-registry after making the above changes.

sudo restart glance-api
sudo restart glance-registry
  Export the following environment variables.

   export SERVICE_TOKEN=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=admin
export OS_AUTH_URL="http://localhost:5000/v2.0/"
export SERVICE_ENDPOINT=http://localhost:35357/v2.0

  Alternatively, you can add these variables to ~/.bashrc.
  To test if glance is setup correectly execute the following command.

glance index
  The above command will not return any output. The output of the last command executed can be known from its return code - echo $?. If the return code is zero, then glance is setup properly and connects with Keystone.
  With glance configured properly and using keystone as the authentication mechanism, now we can upload images to glance. This has been explained in detail in "Image Management" chapter.
