1. Nova 데이터 베이스 설정하기(Controller서버에서 진행)

nova, nova_api, nova_cell0 데이터베이스 생성
nova_cell0 데이터 베이스는 nova-api, nova-conductor, nova-compute 서비스에 의해 사용되며 스케줄링에 실패한 인스턴스의 정보를 저장합니다.

placement의 경우, 인스턴스 생성에 필요한 자원과 나머지 자원 그리고 전체 사용량에 대한 정보를 저장하기 위해 사용됩니다.

root@controller:~# su -s /bin/bash nova -c "nova-manage api_db sync"
root@controller:~# su -s /bin/bash nova -c "nova-manage cell_v2 map_cell0"
root@controller:~# su -s /bin/bash nova -c "nova-manage db sync"

5. 서비스 재시작

root@controller:~# systemctl restart apache2
root@controller:~# for service in api conductor scheduler novncproxy;do
> systemctl restart nova-$service
> done

root@controller:~# openstack compute service list
+----+----------------+------------+----------+---------+-------+----------------------------+

| 9 | nova-scheduler | controller | internal | enabled | up | None |
+----+----------------+------------+----------+---------+-------+----------------------------+

 

6. 방화벽

 

tcp/6080 포트 열어줍니다. (nova-novncproxy)

tcp/8774 포트 열어줍니다. (nova-api)

tcp/8775 포트 열어줍니다. (nova-metadata)

tcp/8778 포트 열어줍니다. (nova-placement-api)

 

 

 

---

 

 

1. Nova 패키지 설치(Compute Node 에서 진행)

root@compute:~# apt-get install nova-compute nova-compute-kvm

 

2. Nova 설정파일 수정

root@compute:~# cat /etc/nova/nova.conf
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:RABBIT_PASS@controller
my_ip = 192.168.198.102
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api]
auth_strategy = keystone

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:5000
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

vncserver_proxyclient_address = 192.168.198.102
novncproxy_base_url = http://controller:6080/vnc_auto.html

[glance]
api_servers = http://controller:9292

[oslo_concurrency]
lock_path = /var/lib/nova/tmp

[placement]
os_region_name = Region01
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

 

3. Nova 서비스 시작

 

가상화 모듈이 지원이 가능한지 확인

root@compute:~# lsmod | grep kvm
kvm_intel             282624  9
kvm                   663552  1 kvm_intel

 

root@compute:~# systemctl restart nova-compute libvirtd

 

※Controller 서버에서 compute 노드 확인

root@controller:~# su -s /bin/bash nova -c "nova-manage cell_v2 discover_hosts"
root@controller:~# openstack compute service list
+----+----------------+------------+----------+---------+-------+----------------------------+
| ID | Binary | Host | Zone | Status | State | Updated At |
+----+----------------+------------+----------+---------+-------+----------------------------+
| 5 | nova-conductor | controller | internal | enabled | up | 2021-05-03T09:41:18.000000 |
| 9 | nova-scheduler | controller | internal | enabled | up | 2021-05-03T09:41:21.000000 |
| 13 | nova-compute | compute | nova | enabled | up | 2021-05-03T09:41:16.000000 |
+----+----------------+------------+----------+---------+-------+----------------------------+

 

새로운 compute 노드를 추가할 때, 새로운 compute 노드들의 등록을 위해 controller 서버에서 nova-manage cell_v2 discover_hosts를 꼭 실행해야 합니다. 또는 /etc/nova/nova.conf 에서 적절한 interval을 설정할 수 있습니다

# vi /etc/nova/nova.conf

[scheduler]

discover_hosts_in_cells_interval = 300
