오픈스택 멀티 노드 설치 - Nova (Controller)

아. Compute service 설치(컨트롤러) 및 설정

---

1) 데이터베이스 설정

mysql

CREATE DATABASE nova_api;

CREATE DATABASE nova;

CREATE DATABASE nova_cell0;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \  IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \  IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \  IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \  IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' \  IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' \  IDENTIFIED BY 'NOVA_DBPASS';

exit

 

2) nova user 생성

. admin-openrc

openstack user create --domain default --password-prompt nova

* 비밀번호: NOVA_PASS

 

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

* service 프로젝트에 넣고 admin 권한 부여

 

3) nova 서비스 엔트리 생성

openstack service create --name nova \  --description "OpenStack Compute" compute

*다른 컴포넌트들이 nova 서비스를 인식하도록 함

 

4) nova 서비스 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

 

5) nova 설치

apt install nova-api nova-conductor nova-novncproxy nova-scheduler

 

6) nova config 파일 설정

vi /etc/nova/nova.conf
