Prerequisites

Before you install and configure the freecell service, you must create a database, service credentials, and API endpoints.

  1. To create the database, complete these steps:

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

      $ mysql -u root -p
      
    • Create the freecell_solver database:

      CREATE DATABASE freecell_solver;
      
    • Grant proper access to the freecell_solver database:

      GRANT ALL PRIVILEGES ON freecell_solver.* TO 'freecell_solver'@'localhost' \
        IDENTIFIED BY 'FREECELL_SOLVER_DBPASS';
      GRANT ALL PRIVILEGES ON freecell_solver.* TO 'freecell_solver'@'%' \
        IDENTIFIED BY 'FREECELL_SOLVER_DBPASS';
      

      Replace FREECELL_SOLVER_DBPASS with a suitable password.

    • Exit the database access client.

      exit;
      
  2. Source the admin credentials to gain access to admin-only CLI commands:

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

    • Create the freecell_solver user:

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

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

      $ openstack service create --name freecell_solver --description "freecell" freecell
      
  4. Create the freecell service API endpoints:

    $ openstack endpoint create --region RegionOne \
      freecell public http://controller:XXXX/vY/%\(tenant_id\)s
    $ openstack endpoint create --region RegionOne \
      freecell internal http://controller:XXXX/vY/%\(tenant_id\)s
    $ openstack endpoint create --region RegionOne \
      freecell admin http://controller:XXXX/vY/%\(tenant_id\)s
