    오픈스택 수동 설치 실습 #.9 - Controller 노드에 Nova 설치


    Nova 설치 준비


    SQL DB에 접속하여 nova, placement 2개의 유저를 생성합니다. DB계정에 대한 password는 보기 편하게 user와 동일하게 설정 했습니다.

    Database nova, nova-api, nova_cell0, placement 4개의 DB를 생성합니다.

    # su - postgres

    $ psql

    postgres=# create database nova;

    postgres=# create database nova_api;

    postgres=# create database nova_cell0;

    postgres=# create database placement;


    postgres=# create role nova with login;

    postgres=# create role placement with login;


    postgres=# grant all privileges on database nova to nova;

    postgres=# grant all privileges on database nova_api to nova;

    postgres=# grant all privileges on database nova_cell0 to nova;

    postgres=# grant all privileges on database placement to placement;


    postgres=# alter user nova with encrypted password 'nova';

    postgres=# alter user placement with encrypted password 'placement';

    keystone 인증 불러오기

    # . admin-openrc

    Nova 유저를 생성합니다.

    $ openstack user create --domain Default --password-prompt nova

    Nova 유저에 admin 권한을 줍니다.

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

    Nova 서비스 엔티티 생성

    $ openstack service create --name nova \

      --description "OpenStack Compute" compute

    Compute API 엔드포인트 생성

    $ openstack endpoint create --region RegionOne \

      compute public http://controller:8774/v2.1


    $ openstack endpoint create --region RegionOne \

      compute internal http://controller:8774/v2.1

      

    $ openstack endpoint create --region RegionOne \

      compute admin http://controller:8774/v2.1

    Placement 서비스 유저 생성

    $ openstack user create --domain Default --password-prompt placement

    Placement 서비스 유저에 admin 권한부여

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

    Placement 서비스 생성

    $ openstack service create --name placement \

      --description "Placement API" placement

    Placement API 엔드포인트 생성

    $ openstack endpoint create --region RegionOne \

      placement public http://controller:8778

      

    $ openstack endpoint create --region RegionOne \

      placement internal http://controller:8778


    $ openstack endpoint create --region RegionOne \

      placement admin http://controller:8778


    Nova 패키지 설치 및 설정

    # yum install openstack-nova-api openstack-nova-conductor \

      openstack-nova-console openstack-nova-novncproxy \

      openstack-nova-scheduler openstack-nova-placement-api

    # vi /etc/nova/nova.conf

    [DEFAULT]

    # ...

    enabled_apis = osapi_compute,metadata

    transport_url = rabbit://openstack:RABBIT_PASS@controller

    my_ip = 10.0.0.11


    [api_database]

    # ...

    connection = postgresql://nova:nova@controller/nova_api


    [database]

    # ...

    connection = postgresql://nova:nova@controller/nova


    [placement_database]

    # ...

    connection = postgresql://placement:placement@controller/placement


    [api]

    # ...

    auth_strategy = keystone


    [keystone_authtoken]

    # ...

    auth_url = http://controller:5000/v3

    memcached_servers = controller:11211

    auth_type = password

    project_domain_name = Default

    user_domain_name = Default

    project_name = service

    username = nova

    password = NOVA_PASS


    [vnc]

    enabled = true

    # ...

    server_listen = 10.0.0.11

    server_proxyclient_address = 10.0.0.11


    [oslo_concurrency]

    # ...

    lock_path = /var/lib/nova/tmp


    [placement]

    # ...

    region_name = RegionOne

    project_domain_name = Default

    project_name = service

    auth_type = password

    user_domain_name = Default

    auth_url = http://controller:5000/v3

    username = placement

    password = PLACEMENT_PASS

    Placement API 설정에 15째줄에 아래 내용을 추가해줘야 합니다.

    # vi /etc/httpd/conf.d/00-nova-placement-api.conf

      <Directory /usr/bin>
        Require all granted
      </Directory>

    # semanage port -a -t http_port_t -p tcp 8778

    Nova-api DB와 placement DB에 배포

    # su -s /bin/bash nova -c "nova-manage api_db sync"

    cell0 데이터베이스 등록

    # su -s /bin/bash nova -c "nova-manage cell_v2 map_cell0"

    cell1 cell 생성

    # su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

    Nova DB에 배포

    # su -s /bin/bash nova -c "nova-manage db sync"

    Nova 리스트에 cell0과 cell1을 등록

    # ssu -s /bin/bash nova -c "nova-manage cell_v2 create_cell --name cell1"

    httpd 재시작

    # systemctl restart httpd


    Nova 서비스 생성 및 자동실행 등록

    # for service in api consoleauth conductor scheduler novncproxy; do
    systemctl start openstack-nova-$service
    systemctl enable openstack-nova-$service
    done


    Controller 노드에 Nova 설치가 끝났습니다.

    이어서 Compute 노드에 Nova를 설치해야 합니다.
