Openstack(Kilo)安装系列之glance（六）

安装配置

Before you install and configure the Image service, you must create a database, service credentials, and API endpoint.

一、创建glance数据库并授权

1.登陆数据库

mysql -u root -p

2.创建数据库并授权

CREATE DATABASE glance;
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.

3.Source the admin credentials to gain access to admin-only CLI commands:

source admin-openrc.sh

4.To create the service credentials, complete these steps:

Create the glance user:

openstack user create --password-prompt glance

Add the admin role to the glance user and service project:

openstack role add --project service --user glance admin

Create the glance service entity:

openstack service create --name glance 
  --description "OpenStack Image service" image

Create the Image service API endpoint:

openstack endpoint create 
  --publicurl http://controller:9292 
  --internalurl http://controller:9292 
  --adminurl http://controller:9292 
  --region RegionOne 
  image

二、To install and configure the Image service components

1.Install the packages:

yum install openstack-glance python-glance python-glanceclient

2.Edit the /etc/glance/glance-api.conf file and complete the following actions:

In the [database] section, configure database access:

[database]
...
connection = mysql://glance:GLANCE_DBPASS@controller/glance

Replace GLANCE_DBPASS with the password you chose for the Image service database.

In the [keystone_authtoken] and [paste_deploy] sections, configure Identity service access:

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = glance
password = GLANCE_PASS
 
[paste_deploy]
...
flavor = keystone

Replace GLANCE_PASS with the password you chose for the glance user in the Identity service.

注意：Comment out or remove any other options in the [keystone_authtoken] section.

In the [glance_store] section, configure the local file system store and location of image files:

[glance_store]
...
default_store = file
filesystem_store_datadir = /var/lib/glance/images/

In the [DEFAULT] section, configure the noop notification driver to disable notifications because they only pertain to the optional Telemetry service:

[DEFAULT]
...
notification_driver = noop

The Telemetry chapter provides an Image service configuration that enables notifications.

(Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:

[DEFAULT]
...
verbose = True

3.Edit the /etc/glance/glance-registry.conf file and complete the following actions:

In the [database] section, configure database access:

[database]
...
connection = mysql://glance:GLANCE_DBPASS@controller/glance

Replace GLANCE_DBPASS with the password you chose for the Image service database.

In the [keystone_authtoken] and [paste_deploy] sections, configure Identity service access:

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = glance
password = GLANCE_PASS
 
[paste_deploy]
...
flavor = keystone

Replace GLANCE_PASS with the password you chose for the glance user in the Identity service.

注意：Comment out or remove any other options in the [keystone_authtoken] section.

In the [DEFAULT] section, configure the noop notification driver to disable notifications because they only pertain to the optional Telemetry service:

[DEFAULT]
...
notification_driver = noop

The Telemetry chapter provides an Image service configuration that enables notifications.

(Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:

[DEFAULT]
...
verbose = True

4.Populate the Image service database:

su -s /bin/sh -c "glance-manage db_sync" glance

To finalize installation

Start the Image service services and configure them to start when the system boots:

systemctl enable openstack-glance-api.service openstack-glance-registry.service
systemctl start openstack-glance-api.service openstack-glance-registry.service
