Menginstal dan mengkonfigurasi controller node.

Menginstal dan mengkonfigurasi controller node.

Bagian ini menjelaskan cara menginstal dan mengkonfigurasi layanan Compute, code-named nova, pada controller node.

Prasyarat

Sebelum Anda menginstal dan mengkonfigurasi layanan Compute, Anda harus membuat database, kredensial layanan, dan API endpoints.

  1. Untuk membuat database, lakukan langkah-langkah berikut:

    • Gunakan klien akses database untuk menghubungkan ke server database sebagai root user:

      $ mysql -u root -p
      
    • Create the nova_api, nova, and nova_cell0 databases:

      MariaDB [(none)]> CREATE DATABASE nova_api;
      MariaDB [(none)]> CREATE DATABASE nova;
      MariaDB [(none)]> CREATE DATABASE nova_cell0;
      
    • Berikanlah akses yang tepat untuk database:

      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
        IDENTIFIED BY 'NOVA_DBPASS';
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \
        IDENTIFIED BY 'NOVA_DBPASS';
      
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
        IDENTIFIED BY 'NOVA_DBPASS';
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
        IDENTIFIED BY 'NOVA_DBPASS';
      
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' \
        IDENTIFIED BY 'NOVA_DBPASS';
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' \
        IDENTIFIED BY 'NOVA_DBPASS';
      

      Ganti NOVA_DBPASS dengan password yang sesuai.

    • Keluar dari klien akses database.

  2. Dapatkan sumber `admin credential untuk akses ke admin-only CLI commands:

    $ . admin-openrc
    
  3. Create the Compute service credentials:

    • Buat pengguna nova:

      $ openstack user create --domain default --password-prompt nova
      
      User Password:
      Repeat User Password:
      +---------------------+----------------------------------+
      | Field               | Value                            |
      +---------------------+----------------------------------+
      | domain_id           | default                          |
      | enabled             | True                             |
      | id                  | 8a7dbf5279404537b1c7b86c033620fe |
      | name                | nova                             |
      | options             | {}                               |
      | password_expires_at | None                             |
      +---------------------+----------------------------------+
      
    • Tambahkan peran admin ke pengguna nova:

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

      Catatan

      Command ini tidak memberikan output.

    • Buat entitas layanan nova:

      $ openstack service create --name nova \
        --description "OpenStack Compute" compute
      
      +-------------+----------------------------------+
      | Field       | Value                            |
      +-------------+----------------------------------+
      | description | OpenStack Compute                |
      | enabled     | True                             |
      | id          | 060d59eac51b4594815603d75a00aba2 |
      | name        | nova                             |
      | type        | compute                          |
      +-------------+----------------------------------+
      
  4. Create the Compute API service endpoints:

    $ openstack endpoint create --region RegionOne \
      compute public http://controller:8774/v2.1
    
    +--------------+-------------------------------------------+
    | Field        | Value                                     |

Menginstal dan mengkonfigurasi komponen

Catatan

file konfigurasi default bervariasi oleh distribusi. Anda mungkin perlu menambahkan bagian ini dan pilihan daripada memodifikasi bagian dan pilihan yang ada. Juga, elipsis (`` ... ``) dalam cuplikan konfigurasi menunjukkan opsi konfigurasi default potensial yang harus Anda mempertahankan.

  1. Instal paket:

    # yum install openstack-nova-api openstack-nova-conductor \
      openstack-nova-console openstack-nova-novncproxy \
      openstack-nova-scheduler openstack-nova-placement-api
    
  1. Edit file /etc/nova/nova.conf dan selesaikan tindakan berikut:

    • Dalam bagian ``[DEFAULT] ``, aktifkan hanya komputasi dan metadata API:

      [DEFAULT]
      # ...
      enabled_apis = osapi_compute,metadata
      
    • Dalam bagian [api_database] dan `` [Database] ``, konfigurasi akses database:

      [api_database]
      # ...
      connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova_api
      
      [database]
      # ...
      connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova
      

      Ganti NOVA_DBPASS dengan password yang Anda pilih untuk database Compute.

    • Dalam bagian [DEFAULT], lakukan konfigurasi akses antrian pesan RabbitMQ:

      [DEFAULT]
      # ...
      transport_url = rabbit://openstack:RABBIT_PASS@controller
      

      Ganti RABBIT_PASS dengan password yang Anda pilih untuk akun openstack di `` RabbitMQ``.

    • Dalam bagian ``[api] `` dan ``[keystone_authtoken] ``, lakukan konfigurasi akses layanan Identity:

      [api]
      # ...
      auth_strategy = keystone
      
      [keystone_authtoken]
      # ...
      auth_uri = http://controller:5000
      auth_url = http://controller:35357
      memcached_servers = controller:11211
      auth_type = password
      project_domain_name = default
      user_domain_name = default
      project_name = service
      username = nova
      password = NOVA_PASS
      

      Ganti NOVA_PASS dengan password yang Anda pilih untuk pengguna nova dalam pelayanan Identity.

      Catatan

      Hilangkan komentar atau bahkan hapus pilihan lainnya dalam bagian ``[keystone_authtoken] ``.

    • Dalam bagian [DEFAULT] ``, konfigurasi opsi ``my_ip menggunakan management interface alamat IP dari controller node:

      [DEFAULT]
      # ...
      my_ip = 10.0.0.11
      
  • Dalam bagian ``[DEFAULT] ``, aktifkan dukungan untuk layanan Networking:

    [DEFAULT]
    # ...
    use_neutron = True
    firewall_driver = nova.virt.firewall.NoopFirewallDriver
    

    Catatan

    Secara default, Compute menggunakan driver firewall internal. Karena layanan Networking termasuk driver firewall, Anda harus menonaktifkan driver firewall Compute dengan menggunakan driver firewall nova.virt.firewall.NoopFirewallDriver.

  • Dalam bagian ``[vnc] ``, konfigurasi proxy VNC menggunakan manajemen antarmuka alamat IP dari controller node:

    [vnc]
    enabled = true
    # ...
    vncserver_listen = $my_ip
    vncserver_proxyclient_address = $my_ip
    
  • Dalam bagian ``[glance] ``, konfigurasikan lokasi layanan Image API:

    [glance]
    # ...
    api_servers = http://controller:9292
    
  • Dalam bagian [oslo_concurrency], konfigurasi lock path:

    [oslo_concurrency]
    # ...
    lock_path = /var/lib/nova/tmp
    
  • In the [placement] section, configure the Placement API:

    [placement]
    # ...
    os_region_name = RegionOne
    project_domain_name = Default
    project_name = service
    auth_type = password
    user_domain_name = Default
    auth_url = http://controller:35357/v3
    username = placement
    password = PLACEMENT_PASS
    

    Replace PLACEMENT_PASS with the password you choose for the placement user in the Identity service. Comment out any other options in the [placement] section.

  • Due to a packaging bug, you must enable access to the Placement API by adding the following configuration to /etc/httpd/conf.d/00-nova-placement-api.conf:

    <Directory /usr/bin>
       <IfVersion >= 2.4>
          Require all granted
       </IfVersion>
       <IfVersion < 2.4>
          Order allow,deny
          Allow from all
       </IfVersion>
    </Directory>
    
  • Mulai ulang layanan httpd:

    # systemctl restart httpd
    
  1. Populate the nova-api database:

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

    Catatan

    Abaikan pesan bantahan dalam output ini.

  2. Register the cell0 database:

    # su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
    
  3. Create the cell1 cell:

    # su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
    109e1d4b-536a-40d0-83c6-5f121b82b650
    
  4. Populate the nova database:

    # su -s /bin/sh -c "nova-manage db sync" nova
    
  5. Verify nova cell0 and cell1 are registered correctly:

    # nova-manage cell_v2 list_cells
    +-------+--------------------------------------+
    | Name  | UUID                                 |
    +-------+--------------------------------------+
    | cell1 | 109e1d4b-536a-40d0-83c6-5f121b82b650 |
    | cell0 | 00000000-0000-0000-0000-000000000000 |
    +-------+--------------------------------------+
    

Finalisasi instalasi

  • Mulai layanan Compute dan mengkonfigurasi mereka untuk mulai booting:

    # systemctl enable openstack-nova-api.service \
      openstack-nova-consoleauth.service openstack-nova-scheduler.service \
      openstack-nova-conductor.service openstack-nova-novncproxy.service
    # systemctl start openstack-nova-api.service \
      openstack-nova-consoleauth.service openstack-nova-scheduler.service \
      openstack-nova-conductor.service openstack-nova-novncproxy.service
