Prerequisites
-------------

Before you install and configure the Shared File Systems service, you
must create a database, service credentials, and `API endpoints`.

#. To create the database, complete these steps:

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

     .. code-block:: console

        $ mysql -u root -p

   * Create the `manila` database:

     .. code-block:: console

        CREATE DATABASE manila;

   * Grant proper access to the ``manila`` database:

     .. code-block:: console

        GRANT ALL PRIVILEGES ON manila.* TO 'manila'@'localhost' \
          IDENTIFIED BY 'MANILA_DBPASS';
        GRANT ALL PRIVILEGES ON manila.* TO 'manila'@'%' \
          IDENTIFIED BY 'MANILA_DBPASS';

     Replace ``MANILA_DBPASS`` with a suitable password.

   * Exit the database access client.

#. Source the ``admin`` credentials to gain access to admin CLI commands:

   .. code-block:: console

      $ . admin-openrc.sh

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

   * Create a ``manila`` user:

     .. code-block:: console

        $ openstack user create --domain default --password-prompt manila
        User Password:
        Repeat User Password:

        | Field               | Value                            |
        +---------------------+----------------------------------+
        | domain_id           | e0353a670a9e496da891347c589539e9 |
        | enabled             | True                             |
        | id                  | 83a3990fc2144100ba0e2e23886d8acc |
        | name                | manila                           |
        | options             | {}                               |
        | password_expires_at | None                             |
        +---------------------+----------------------------------+

   * Add the ``admin`` role to the ``manila`` user:

     .. code-block:: console

        $ openstack role add --project service --user manila admin

     .. note::

        This command provides no output.

   * Create the ``manila`` and ``manilav2`` service entities:

     .. code-block:: console

        $ openstack service create --name manila \
          --description "OpenStack Shared File Systems" share
          +-------------+----------------------------------+
          | Field       | Value                            |
          +-------------+----------------------------------+
          | description | OpenStack Shared File Systems    |
          | enabled     | True                             |
          | id          | 82378b5a16b340aa9cc790cdd46a03ba |
          | name        | manila                           |
          | type        | share                            |
          +-------------+----------------------------------+

     .. code-block:: console

        $ openstack service create --name manilav2 \
          --description "OpenStack Shared File Systems V2" sharev2
          +-------------+----------------------------------+
          | Field       | Value                            |
          +-------------+----------------------------------+
          | description | OpenStack Shared File Systems V2 |
          | enabled     | True                             |
          | id          | 30d92a97a81a4e5d8fd97a32bafd7b88 |
          | name        | manilav2                         |
          | type        | sharev2                          |
          +-------------+----------------------------------+

     .. note::

        The Shared File Systems services require two service entities.

#. Create the Shared File Systems service API endpoints:

   .. code-block:: console

      $ openstack endpoint create --region RegionOne \
        sharev2 public http://controller:8786/v2
