KATO Tomoyuki 95847f47e2 [install] remove Debian specific procedure from tool 
This is a following patch of I8df6b3b382137d08d60f85bc41bcd98ac1f4eb47
"Factor out Install Guide for Debian with debconf".
Mainly, remove Debian specific procedure from build tool.
Also, remove debconf content from Debian Install Guide,
but there are still some debconf content, which is needed to

Install and configure

This section describes how to install and configure the OpenStack Identity service, code-named keystone, on the controller node. For performance, this configuration deploys Fernet tokens and the Apache HTTP server to handle requests.

obs or rdo or ubuntu

Prerequisites

Before you configure the OpenStack Identity service, you must create a database and an administration token.

  1. To create the database, complete the following actions:

    • Use the database access client to connect to the database server as the root user:

      $ mysql -u root -p

    • Create the keystone database:

      CREATE DATABASE keystone;

    • Grant proper access to the keystone database:

      GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
  IDENTIFIED BY 'KEYSTONE_DBPASS';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
  IDENTIFIED BY 'KEYSTONE_DBPASS';

      Replace KEYSTONE_DBPASS with a suitable password.

    • Exit the database access client.

  2. Generate a random value to use as the administration token during initial configuration:

    $ openssl rand -hex 10

obs or rdo or ubuntu

Install and configure components

Note

This guide uses the Apache HTTP server with mod_wsgi to serve Identity service requests on ports 5000 and 35357. By default, the keystone service still listens on these ports. Therefore, this guide manually disables the keystone service.

ubuntu

  1. Disable the keystone service from starting automatically after installation:

    # echo "manual" > /etc/init/keystone.override

  2. Run the following command to install the packages:

    ubuntu

    # apt-get install keystone apache2 libapache2-mod-wsgi

obs or rdo

  1. Run the following command to install the packages:

    rdo

    # yum install openstack-keystone httpd mod_wsgi

    obs

    # zypper install openstack-keystone apache2-mod_wsgi

obs or rdo or ubuntu

  1. Edit the /etc/keystone/keystone.conf file and complete the following actions:

    • In the [DEFAULT] section, define the value of the initial administration token:

      [DEFAULT]
...
admin_token = ADMIN_TOKEN

      Replace ADMIN_TOKEN with the random value that you generated in a previous step.

    • In the [database] section, configure database access:

      [database]
...
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone

      Replace KEYSTONE_DBPASS with the password you chose for the database.

    • In the [token] section, configure the Fernet token provider:

      [token]
...
provider = fernet

rdo or ubuntu or obs

  1. Populate the Identity service database:

    # su -s /bin/sh -c "keystone-manage db_sync" keystone

    Note

    Ignore any deprecation messages in this output.

  2. Initialize Fernet keys:

    # keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

debian

Install and configure the components

  1. Run the following command to install the packages:

    # apt-get install keystone

  2. Respond to prompts for debconf, which will fill the below database access directive.

    [database]
...
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone

    If you decide to not use dbconfig-common, then you have to create the database and manage its access rights yourself, and run the following by hand.

    # keystone-manage db_sync

  3. Generate a random value to use as the administration token during initial configuration:

    $ openssl rand -hex 10

  4. Configure the initial administration token:

    image

    Use the random value that you generated in a previous step. If you install using non-interactive mode or you do not specify this token, the configuration tool generates a random value.

    Later on, the package will configure the below directive with the value you entered:

    [DEFAULT]
...
admin_token = ADMIN_TOKEN

  5. Create the admin project and user:

    During the final stage of the package installation, it is possible to automatically create an admin and service project, and an admin user. This can later be used for other OpenStack services to contact the Identity service. This is the equivalent of running the below commands:

    # openstack --os-token ${AUTH_TOKEN} \
  --os-url=http://127.0.0.1:35357/v3/ \
  --os-domain-name default \
  --os-identity-api-version=3 \
  project create --or-show \
  admin --domain default \
  --description "Default Debian admin project"

# openstack --os-token ${AUTH_TOKEN} \
  --os-url=http://127.0.0.1:35357/v3/ \
  --os-domain-name default \
  --os-identity-api-version=3 \
  project create --or-show \
  service --domain default \
  --description "Default Debian admin project"

# openstack --os-token ${AUTH_TOKEN} \
  --os-url=http://127.0.0.1:35357/v3/ \
  --os-domain-name default \
  --os-identity-api-version=3 \
  user create --or-show \
  --password ADMIN_PASS \
  --project admin \
  --email root@localhost \
  --enable \
  admin \
  --domain default \
  --description "Default Debian admin user"

# openstack --os-token ${AUTH_TOKEN} \
  --os-url=http://127.0.0.1:35357/v3/ \
  --os-domain-name default \
  --os-identity-api-version=3 \
  role create --or-show admin

# openstack  --os-token ${AUTH_TOKEN} \
  --os-url=http://127.0.0.1:35357/v3/ \
  --os-domain-name default \
  --os-identity-api-version=3 \
  role add --project admin --user admin admin

    In Debian, the Keystone package offers automatic registration of Keystone in the service catalogue. This is equivalent of running the below commands:

    # openstack --os-token ${AUTH_TOKEN} \
  --os-url=http://127.0.0.1:35357/v3/ \
  --os-domain-name default \
  --os-identity-api-version=3 \
  service create \
  --name keystone \
  --description "OpenStack Identity" \
  identity

# openstack --os-token ${AUTH_TOKEN} \
  --os-url=http://127.0.0.1:35357/v3/ \
  --os-domain-name default \
  --os-identity-api-version=3 \
  keystone public http://controller:5000/v2.0

# openstack --os-token ${AUTH_TOKEN} \
  --os-url=http://127.0.0.1:35357/v3/ \
  --os-domain-name default \
  --os-identity-api-version=3 \
  keystone internal http://controller:5000/v2.0

# openstack --os-token ${AUTH_TOKEN} \
  --os-url=http://127.0.0.1:35357/v3/ \
  --os-domain-name default \
  --os-identity-api-version=3 \
  keystone admin http://controller:35357/v2.0

ubuntu or rdo or obs

Finalize the installation

ubuntu

  1. Restart the Apache HTTP server:

    # service apache2 restart

  2. By default, the Ubuntu packages create an SQLite database.

    Because this configuration uses an SQL database server, you can remove the SQLite database file:

    # rm -f /var/lib/keystone/keystone.db

rdo

  • Start the Apache HTTP service and configure it to start when the system boots:

    # systemctl enable httpd.service
# systemctl start httpd.service

obs

  1. Start the Apache HTTP service and configure it to start when the system boots:

    # systemctl enable apache2.service
# systemctl start apache2.service
