学校実験室で単一ノードOpenStack–Placementを構築する(5)

1.データベース構築

# mysql
MariaDB [(none)]> CREATE DATABASE placement;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' \
  IDENTIFIED BY 'PLACEMENT_DB_비밀번호';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' \
  IDENTIFIED BY 'PLACEMENT_DB_비밀번호';

2.ユーザーとエンドポイントの構成

#. admin-openrc
# openstack user create --domain default --password-prompt placement

User Password:
Repeat User Password:

user_domain_name = Default
project_name = service
username = placement
password = PLACEMENT_DB_비밀번호

# su -s /bin/sh -c "placement-manage db sync" placement
