OpenStack 설치 학습서#

5. Placement#

Placement service는 리소스의 사용량을 추적하는데 사용되는 서비스입니다.

Placement은 Keystone 설치 이후에 설치하는 서비스이며, 본 학습서에서는 Controller node에서 설치를 진행합니다.

• Controller node
  • 사전 설정

    CONTROLLER_IP=192.168.0.150
    OPENSTACK_PASSWORD=passwds

  • 데이터베이스에 서비스 생성

    mysql -e "CREATE DATABASE placement;"
    mysql -e "GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY '${OPENSTACK_PASSWORD}';"
    mysql -e "GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY '${OPENSTACK_PASSWORD}';"
    mysql -e "FLUSH PRIVILEGES;"

  • admin 커맨드 액세스

    . admin-openrc

  • 서비스 자격 증명 및 생성

    openstack user create --domain default --password ${OPENSTACK_PASSWORD} placement
    openstack role add --project service --user placement admin
    openstack service create --name placement --description "Placement API" placement

    • 
  • API 엔드포인트를 생성

    openstack endpoint create --region RegionOne placement public http://${CONTROLLER_IP}:8778
    openstack endpoint create --region RegionOne placement internal http://${CONTROLLER_IP}:8778
    openstack endpoint create --region RegionOne placement admin http://${CONTROLLER_IP}:8778

    • 
  • 패키지 설치 및 설정

    apt install -y placement-api
    # placement.conf 파일 수정
    crudini --set /etc/placement/placement.conf placement_database connection mysql+pymysql://placement:${OPENSTACK_PASSWORD}@${CONTROLLER_IP}/placement
    crudini --set /etc/placement/placement.conf api auth_strategy keystone
    crudini --set /etc/placement/placement.conf keystone_authtoken auth_url http://${CONTROLLER_IP}:5000/v3
    crudini --set /etc/placement/placement.conf keystone_authtoken memcached_servers ${CONTROLLER_IP}:11211
    crudini --set /etc/placement/placement.conf keystone_authtoken auth_type password
    crudini --set /etc/placement/placement.conf keystone_authtoken project_domain_name Default
    crudini --set /etc/placement/placement.conf keystone_authtoken user_domain_name Default
    crudini --set /etc/placement/placement.conf keystone_authtoken project_name service
    crudini --set /etc/placement/placement.conf keystone_authtoken username placement
    crudini --set /etc/placement/placement.conf keystone_authtoken password ${OPENSTACK_PASSWORD}

    • 
  • 데이터베이스 설정

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

  • 서비스 재시작

    service apache2 restart
    # 서비스 확인
    placement-status upgrade check
