Install and configure for openSUSE and SUSE Linux Enterprise

Install and configure for openSUSE and SUSE Linux Enterprise

This section describes how to install and configure the DNS service for openSUSE Leap 42.2 and SUSE Linux Enterprise Server 12 SP2.


Before you install and configure the DNS service, you must create service credentials and API endpoints.

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

    $ source admin-openrc
  2. To create the service credentials, complete these steps:

    • Create the designate user:

      $ openstack user create --domain default --password-prompt designate
    • Add the admin role to the designate user:

      $ openstack role add --project service --user designate admin
    • Create the designate service entities:

      $ openstack service create --name designate --description "DNS" dns
  3. Create the DNS service API endpoint:

    $ openstack endpoint create --region RegionOne \
      dns public http://controller:9001/

Install and configure components


Default configuration files vary by distribution. You might need to add these sections and options rather than modifying existing sections and options. Also, an ellipsis (...) in the configuration snippets indicates potential default configuration options that you should retain.

  1. Install the packages:

    # zypper install openstack-designate\*
  2. Create a designate database that is accessible by the designate user. Replace DESIGNATE_DBPASS with a suitable password:

    # mysql -u root -p
    MariaDB [(none)]> CREATE DATABASE designate CHARACTER SET utf8 COLLATE utf8_general_ci;
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON designate.* TO 'designate'@'localhost' \
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON designate.* TO 'designate'@'%' \
  3. Install the BIND packages:

    # zypper install bind bind-utils
  4. Add the following options in the /etc/named.conf file:

    options {
        allow-new-zones yes;
        request-ixfr no;
        listen-on port 53 {; };
        recursion no;
        allow-query {; };
  5. Create an RNDC Key:

    # rndc-confgen -a -k designate -c /etc/designate/rndc.key -r /dev/urandom
  6. Add the key to /etc/named.conf:

    include "/etc/designate/rndc.key";
    controls {
      inet port 953
        allow {; } keys { "designate"; };
  7. Start the DNS service and configure it to start when the system boots:

    # systemctl enable named
    # systemctl start named
  8. Edit the /etc/designate/designate.conf file and complete the following actions:

    • In the [service:api] section, configure auth_strategy:

      listen =
      auth_strategy = keystone
      api_base_uri = http://controller:9001/
      enable_api_v2 = True
      enabled_extensions_v2 = quotas, reports
    • In the [keystone_authtoken] section, configure the following options:

      auth_type = password
      username = designate
      password = DESIGNATE_PASS
      project_name = service
      project_domain_name = Default
      user_domain_name = Default
      www_authenticate_uri = http://controller:5000/
      auth_url = http://controller:5000/

      Replace DESIGNATE_PASS with the password you chose for the designate user in the Identity service.

    • In the [service:worker] section, enable the worker model:

      enabled = True
      notify = True
    • In the [storage:sqlalchemy] section, configure database access:

      connection = mysql+pymysql://designate:DESIGNATE_DBPASS@controller/designate

      Replace DESIGNATE_DBPASS with the password you chose for the designate database.

    • Populate the designate database

      # su -s /bin/sh -c "designate-manage database sync" designate
  9. Start the designate central and API services and configure them to start when the system boots:

    # systemctl enable openstack-designate-central openstack-designate-api
    # systemctl start openstack-designate-central openstack-designate-api
  10. Create a pools.yaml file in /etc/designate/pools.yaml with the following contents:

    - name: default
      # The name is immutable. There will be no option to change the name after
      # creation and the only way will to change it will be to delete it
      # (and all zones associated with it) and recreate it.
      description: Default Pool
      attributes: {}
      # List out the NS records for zones hosted within this pool
      # This should be a record that is created outside of designate, that
      # points to the public IP of the controller node.
        - hostname:
          priority: 1
      # List out the nameservers for this pool. These are the actual BIND servers.
      # We use these to verify changes have propagated to all nameservers.
        - host:
          port: 53
      # List out the targets for this pool. For BIND there will be one
      # entry for each BIND server, as we have to run rndc command on each server
        - type: bind9
          description: BIND9 Server 1
          # List out the designate-mdns servers from which BIND servers should
          # request zone transfers (AXFRs) from.
          # This should be the IP of the controller node.
          # If you have multiple controllers you can add multiple masters
          # by running designate-mdns on them, and adding them here.
            - host:
              port: 5354
          # BIND Configuration options
            port: 53
            rndc_port: 953
            rndc_key_file: /etc/designate/rndc.key
  11. Update the pools:

    # su -s /bin/sh -c "designate-manage pool update" designate
  12. Start the designate and mDNS services and configure them to start when the system boots:

    # systemctl enable openstack-designate-worker openstack-designate-producer openstack-designate-mdns
    # systemctl start openstack-designate-worker openstack-designate-producer openstack-designate-mdns
