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                                     |

+--------------+-------------------------------------------+

  5. Create a Placement service user using your chosen PLACEMENT_PASS:

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

User Password:
Repeat User Password:
+---------------------+----------------------------------+
| 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:

    # zypper install openstack-nova-api openstack-nova-scheduler \
  openstack-nova-conductor openstack-nova-consoleauth \
  openstack-nova-novncproxy openstack-nova-placement-api \
  iptables

  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/run/nova

  • 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.

  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

  • Enable the placement API Apache vhost:

    # mv /etc/apache2/vhosts.d/nova-placement-api.conf.sample /etc/apache2/vhosts.d/nova-placement-api.conf
# systemctl reload apache2.service

  • 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
