학교 랩실에서 단일노드 Openstack 구축하기 - Placement(5)

1. DB 구축

# 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. 사용자와 엔드포인트 구성

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

User Password:
Repeat User Password:

3. 설치과 컴포넌트 설정

# apt install placement-api
# vim /etc/placement/placement.conf
[placement_database]
# ...
connection = mysql+pymysql://placement:PLACEMENT_DB_비밀번호@localhost/placement

[api]
# ...
auth_strategy = keystone

[keystone_authtoken]
# ...
auth_url = http://localhost:5000/v3
memcached_servers = localhost:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = placement
password = PLACEMENT_DB_비밀번호

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

user_name, password, project_domain_name 및 user_domain_name 값은 keystone설정과 동기화되어야 한다.

4. 설치 완료

# service apache2 restart

5. 작동 확인

# . admin-openrc
# placement-status upgrade check
+----------------------------------+
| Upgrade Check Results            |
+----------------------------------+
| Check: Missing Root Provider IDs |
| Result: Success                  |
| Details: None                    |

| Result: Success                  |
| Details: None                    |
