OpenStack 설치 학습서#

6. Nova#

OpenStack Compute service는 클라우드 컴퓨팅 시스템을 호스팅하고 관리하는 서비스이며, 해당 서비스는 Nova라고 합니다.

Nova은 Keystone, Glance, Placement 설치 이후에 설치하는 서비스입니다. Controller node에는 compute management와 api 등을 설치하고, Compute node는 compute를 위한 하이퍼바이저 등을 설치합니다.

• Controller node
  • 사전설정

    CONTROLLER_IP=192.168.0.150
    OPENSTACK_PASSWORD=passwds

  • 데이터베이스에 서비스 생성

    mysql -e "CREATE DATABASE nova_api;"
    mysql -e "CREATE DATABASE nova;"
    mysql -e "CREATE DATABASE nova_cell0;"
    mysql -e "GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '${OPENSTACK_PASSWORD}';"
    mysql -e "GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '${OPENSTACK_PASSWORD}';"
    mysql -e "GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '${OPENSTACK_PASSWORD}';"
    mysql -e "GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '${OPENSTACK_PASSWORD}';"
    mysql -e "GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY '${OPENSTACK_PASSWORD}';"
    mysql -e "GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY '${OPENSTACK_PASSWORD}';"
    mysql -e "FLUSH PRIVILEGES;"

  • admin 커맨드 액세스

    . admin-openrc

  • 서비스 자격 증명 및 생성

    openstack user create --domain default --password ${OPENSTACK_PASSWORD} nova
    openstack role add --project service --user nova admin
    openstack service create --name nova --description "OpenStack Compute" compute

    • 
  • API 엔드포인트를 생성

    openstack endpoint create --region RegionOne compute public http://${CONTROLLER_IP}:8774/v2.1
    openstack endpoint create --region RegionOne compute internal http://${CONTROLLER_IP}:8774/v2.1
    openstack endpoint create --region RegionOne compute admin http://${CONTROLLER_IP}:8774/v2.1
