openstack 수동 설정 placement

openstack 수동설정 사전 작업

* 사전 작업을 먼저 할 것

 

mysql
CREATE DATABASE placement;
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'openstack';
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'openstack';

mysql에서 placement db와 계정을 만들고 권한을 부여 해준다

. admin-openrc # keystone글 참조

# placement 계정 생성
openstack user create --domain default --password-prompt placement

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

# placement 서비스 생성
openstack service create --name placement --description "Placement API" placement

# endpoint 생성
openstack endpoint create --region RegionOne placement public http://controller:8778
openstack endpoint create --region RegionOne placement internal http://controller:8778
openstack endpoint create --region RegionOne placement admin http://controller:8778

openstack에서 사용할 placement 계정/서비스 생성,권한부여를 해주고 endpoint를 만들어준다

apt install -y placement-api
nano /etc/placement/placement.conf 

# placement.conf

[placement_database]
connection = mysql+pymysql://placement:openstack@controller/placement

[api]
auth_strategy = keystone

[keystone_authtoken]
auth_url = http://controller:5000/v3
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = placement
password = openstack

su -s /bin/sh -c "placement-manage db sync" placement
systemctl restart apache2

placement를 설치해주고 conf파일을 수정한 후 db를 초기화 하고 apache를 재시작해준다

 

* nova 연동

앞서 설치한 nova에서 conductor와 scheduler가 계속 down되는걸 확인할수 있는데 placement를 설정한 후엔 잘 실행된다
