• 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
