학교 랩실에서 단일노드 Openstack 구축하기 - Keystone(3)

1. 데이터베이스 구축

# mysql

# MariaDB [(none)]> CREATE DATABASE keystone;
# MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY '키스톤_DB_비밀번호';
# MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY '키스톤_DB_비밀번호';

2. Keystone 설치와 설정

# apt install keystone
# vim /etc/keystone/keystone.conf 

[database]
# ...
connection = mysql+pymysql://keystone:키스톤_DB_비밀번호@localhost/keystone
...

[token]
# ...
provider = fernet
...

# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

# keystone-manage bootstrap --bootstrap-password 관리자_패스워드 \
  --bootstrap-admin-url http://노드_IP_주소:5000/v3/ \
  --bootstrap-internal-url http://노드_IP_주소:5000/v3/ \
  --bootstrap-public-url http://노드_IP_주소:5000/v3/ \
  --bootstrap-region-id RegionOne

• [database] 레이어 부분에서 controller가 아닌 localhost로 해줘야 한다.
  앞으로 모든 설정파일에서 공식 문서와 다르게 localhost를 입력한다.

• 엔드 포인트를 연결해주는 bootstrap 설정 부분에서는 해당 노드의 IP 주소를 사용한다.
  앞으로 모든 설정파일에서 공식 문서와 다르게 노드 IP 주소를 입력한다.

3. HTTP 서버 설정

ServerName을 추가(변경) 한다.

# vim /etc/apache2/apache2.conf

ServerName 노드_IP_주소

4. 설치 완료

# service apache2 restart
# vim admin-openrc

export OS_USERNAME=admin
export OS_PASSWORD=관리자패스워드 
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://노드_IP주소:5000/v3
export OS_IDENTITY_API_VERSION=3

5. 도메인, 프로젝트, 사용자 및 역할 생성

6. 작동 확인

admin과 myuser(사용자)의 토큰을 요청하면서 keystone 서비스의 작동이 잘 되는지 확인한다.
