본 포스팅은 OpenStack의 구성요소들을 수동으로 설치하는 방법에 대한 가이드입니다.
오픈스택은 Core 프로젝트 즉 주요 구성요소로 10가지를 채택하고 있습니다. 이들은 각자의 VM으로 구성되며 VM간의 연결을 위해 하이퍼바이저를 사용합니다. 본 포스팅에서는 각 구성요소들을 하나씩 수동으로 구성해 보고 연결과정에 대해 알아보겠습니다.
★Cloud★/OpenStack [OpenStack] Part 1. kestone (아이덴티티 서비스)
★Cloud★/OpenStack [OpenStack] Part 2. glance (이미지 서비스)
세번째 시간으로 설치할 구성요소는 Compute인 nova입니다.
앞선 포스팅은 위 URL을 참고하세요.
OpenStack 컴퓨트 (nova)는 IaaS 시스템의 주요 부분입니다. 주요 모듈은 Python으로 구현되어 있습니다. Compute는 인증 관리를 위해 Identity Service를 사용하고 사용자 및 관리 인터페이스용으로 대시보드와 상호작용합니다.
OpenStack Compute는 수평으로 확장가능하며, 이미지를 다운로드하여 인스턴스를 시작합니다.
nova는 다음과 같은 구성 요소가 포함되어 있습니다.
- nova-api service
end user의 compute API 호출을 허용하고 응답합니다. 이 서비스는 admin User가 관리작업을 수행할 수 있도록 OpenStack Compute API, Amazon EC2 API등의 API를 지원합니다. 인스턴스를 실행하고 관리 제어하는 역할을 담당합니다.
- nova-api-metadata service
인스턴스의 메타데이터 요청을 수락합니다. nova-network가 설치 된 다중 호스트 모드에서 실행할 때 사용됩니다.
- nova-compute service
하이퍼바이저 API를 통해 VM 인스턴스를 생성하고 종료하는 데몬입니다. 하이퍼바이저는 XenServer / KVM / VMWare등이 있습니다.
- nova-scheduler service
queue에서 VM 인스턴스의 Request를 가져와 가상 시스템이 실행되는 Compute 서버 노드를 결정합니다.
- nova-conductor module
nova-compute service와 데이터베이스 간의 상호 작용을 관리합니다.
- nova-cert module
X509 인증용 nova 인증서 서비스를 제공합니다. EC2 API에서만 필요합니다.
- nova-network worker deamon
nova-compute service와 마찬가지로 queue에서 네트워크 작업을 허용하고 네트워크를 관리합니다.
- nova-consoleauth daemon
Console Proxy가 제공하는 사용자에 대한 토큰을 승인합니다. 하단의 nova-novncproxy와 nova-xvpvncproxy를 참고하십시오.
- nova-novncproxy daemon
VNC 연결을 통해 실행 중인 인스턴스에 액세스하는 프록시를 제공합니다. 브라우저 기반 novnc 클라이언트를 지원합니다.
- nova-xvpvnproxy daemon
VNC 연결을 통해 실행 중인 인스턴스에 액세스하는 프록시를 제공합니다. OpenStack 관련 java 클라이언트를 지원합니다.
- nova-spiceshtml5proxy deamon
SPICE 연결을 통해 실행 중인 인스턴스에 액세스하는 프록시를 제공합니다. 브라우저 기반 HTML5 클라이언트를 지원합니다.
- euca2ools client
클라우드 리소스 관리를 위한 CLI API입니다. OpenStack 모듈은 아니지만 EC2 인터페이스를 지원하도록 nova-api를 구성할 수 있습니다.
- nova client
사용자가 테넌트 관리자 또는 End User에게 명령을 전달할 수 있습니다.
# 참조
The queue - daemon 간의 메시지를 전달하기 위한 대기열. 일반적으로 RabbitMQ와 함께 구현되지만 Apache Qpid 또는 Zero MQ와 같은 AMQP 메시지 대기열로 구현할 수 있습니다.
SQL database - OpenStack Compute는 SQL-Alchemy가 지원하는 모든 데이터베이스를 지원할 수 있습니다. 데이터베이스는 테스트 및 개발 작업용도로 SQLite2, MYSQL, PostgreSQL이 사용됩니다.
OpenStack Compute Service Installation
Compute Service는 nova이라는 프로젝트로 개발되었습니다. OpenStack은 오픈소스로써 이러한 프로젝트들이 핵심프로젝트로 올라가면 이를 실제 OpenStack에 반영하여 사용하고 실제 프로젝트 Name은 Module Name 및 CLI 환경에서 Command로 사용할 수 있습니다.
- 본 테스트는 다음과 같은 환경에서 작성되었습니다.
[nrson@nrsonLinux~$]uname -a

- 본 포스팅에서는 다양한 설치가 이루어짐에 따라 필수로 설치되어야 하는 mysql, rabbitMQ등의 Install과정으 과감히 제거하였습니다. 별도의 포스팅에서 사전에 준비되야 하는 Package의 설치 과정을 설명드리겠습니다.
- 본 포스팅에서 설치되는 패키지들은 apt-get package manager를 통해 수행됩니다.

출력되는 경고는 무시하면 되며, 지금까지 추가했던 glance와 keystone 그리고 nova의 endpoint가 모두 출력됩니다. 어제 glance 문제를 해결하다,,,,, 원인을 못찾아 endpoint를 여러개 생성해더니.. 3세트가 나왔어요.. 나중에 제거할 예정입니다.
3. nova image list 입니다.

어제 작업했던 glance service에 업로드 된 cirros 이미지가 보입니다.
지금까지 OpenStack 구성요소인 컴퓨트(nova) 이미지 서비스를 구성해 보았습니다.
다음시간에는 뉴트론(neutron) 네트워크 서비스에 대해 알아보겠습니다.
