openstack 수동설정 사전 작업

* 사전 작업을 먼저 할 것

 

controller

mysql
create database nova;
create database nova_api;
create database nova_cell0;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'openstack';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'openstack';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'openstack';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'openstack';

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'openstack';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'openstack';

flush privileges;

 

nova용 database와 계정생성, 권한부여를 해준다

. admin-openrc # keystone글 참조

# nova 계정생성
openstack user create --domain default --project service --password-prompt nova

# nova admin 권한 부여
openstack role add --project service --user nova admin

# nova 서비스 생성
openstack service create --name nova --description "OpenStack Compute" compute

# endpoint 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

openstack에서 사용할 nova 계정을 생성하고 권한을 부여한다

nova 서비스를 생성하고 endpoint를 만든다

nova 를 설치하고 conf파일에 아래 내용들을 수정/추가 한다

su -s /bin/sh -c "nova-manage api_db sync" nova # api_db 초기화
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova # cell0 등록
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova # cell1 생성
su -s /bin/sh -c "nova-manage db sync" nova # db 초기화
su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova # cell 확인

systemctl restart nova-api nova-scheduler nova-conductor nova-novncproxy

nova db등을 초기화해주고 nova 서비스들을 재시작 해준다

* nova-compute를 restart해도 계속 down되는데 이것은 neutron을 설정하면 해결된다
