Prerequisites

Before you install and configure the gyan 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 gyan database:

     CREATE DATABASE gyan;

   • Grant proper access to the gyan database:

     GRANT ALL PRIVILEGES ON gyan.* TO 'gyan'@'localhost' \
       IDENTIFIED BY 'GYAN_DBPASS';
     GRANT ALL PRIVILEGES ON gyan.* TO 'gyan'@'%' \
       IDENTIFIED BY 'GYAN_DBPASS';

     Replace GYAN_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 gyan user:

     $ openstack user create --domain default --password-prompt gyan

   • Add the admin role to the gyan user:

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

   • Create the gyan service entities:

     $ openstack service create --name gyan --description "gyan" gyan

4. Create the gyan service API endpoints:

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