Installazione e configurazione del servizio Image (Glance)
Installazione Glance
Server designato per l'installazione: hostname1.domain.
Install the Image service, as root:
# yum install openstack-nova openstack-glance openstack-glance-doc openstack-nova-doc
After installing, you need to delete the sqlite database it creates, then change the configuration to point to the MySQL database.
# rm /var/lib/glance/glance.sqlite
Configurazione keystone
- Rimuovere, se esiste, il file
/var/lib/glance/glance.db
(cioè il DB sqlite). Verrà utilizzato MySQL.
Configuring the Image Service database backend
- Start the MySQL command line client by running
mysql -u root -p
. Enter the MySQL root user's password when prompted.
- To configure the MySQL database, create the glance database:
mysql> CREATE DATABASE glance;
- Create a MySQL user for the newly-created glance database that has full control of the database.
mysql> GRANT ALL ON glance.* TO 'glance'@'%' IDENTIFIED BY '[YOUR_GLANCEDB_PASSWORD]';
Enter quit at the mysql> prompt to exit MySQL.
mysql> quit
Edit the Glance configuration files and paste ini middleware files
- Update
/etc/glance/glance-api-paste.ini
and configure the admin_*
values under [filter:authtoken]
.
[filter:authtoken]
admin_tenant_name = service
admin_user = glance
admin_password = XXXXXXX
- Add this to the end of
/etc/glance/glance-api.conf
and restart openstack-glance-api
to pick up these changed settings.
[paste_deploy]
flavor = keystone
service openstack-glance-api restart
- Add this to the end of
/etc/glance/glance-registry.conf
.
[paste_deploy]
flavor = keystone
- Update
/etc/glance/glance-registry-paste.ini
, configure the admin_*
values under [filter:authtoken]
:
[filter:authtoken]
admin_tenant_name = service
admin_user = glance
admin_password = XXXXXXX
- Ensure that the glance-registry pipeline section includes authtoken:
[pipeline:glance-registry]
#pipeline = context registryapp
# NOTE: use the following pipeline for keystone
pipeline = authtoken auth-context context registryapp
- Ensure that
/etc/glance/glance-registry.conf
points to the MySQL database rather than sqlite.
sql_connection = mysql://glance:yourpassword@131.154.101.242/glance
- Restart
openstack-glance-registry
and openstack-glance-api
services, as root:
# service openstack-glance-registry restart
# service openstack-glance-api restart
- Now you can populate or migrate the database
# glance-manage db_sync
Troubleshooting
- To begin troubleshooting, look at the logs in the
/var/log/glance/registry.log
or /var/log/glance/api.log
- You can find the version of the installation by using the
glance --version
command. The version number 2012.1 corresponds with the Essex release.
