Openstack 설치 (1) - 사전 작업

1. 네트워크 구성

* 외부접속 : 192.168.0.0/24, Gateway : 192.168.0.254

* 내부접속 : 10.10.10.0/24, Gateway : 10.10.10.1

root@controller:~# cat /etc/hosts
127.0.0.1       localhost
127.0.1.1       controller

#controller
192.168.0.221   controller

#network
192.168.0.222   network

#compute
192.168.0.223   compute1
192.168.0.224   compute2
192.168.0.225   compute3
192.168.0.226   compute4

* Interface 설정 : Controller/Compute 노드는 2개의 인터페이스, Network(Neutron) 노드는 3개의 인터페이스 필요

- Cotroller

2. Ubuntu 구성

(1) OS 설치

    - SSH 활성화

(2). sudo 구성
   $ sudo vi /etc/sudoers
      stack   ALL=NOPASSWD: ALL

(3) root 유저 passwd 구성
$ sudo passwd root
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

(4). Ubuntu 1차 update
/etc/apt/sources.list 수정 (us.archive.ubuntu.com -> ftp.daum.net)
:1,$s/us.archive.ubuntu.com/ftp.daum.net/g

# old ubuntu 지원 중단 되어 OS update를 먼저 수행 해야 함
$ sudo apt-get update
$ sudo apt-get dist-upgrade
# neutron 최신 드라이버 구성을 위한 커널 업데이트
$ sudo apt-get install linux-image-generic-lts-saucy linux-headers-generic-lts-saucy
$ sudo reboot

(5) OpenStack Icehouse repository 설치
$ sudo apt-get install python-software-properties
$ sudo add-apt-repository cloud-archive:icehouse
$ sudo apt-get update
$ sudo apt-get dist-upgrade
$ sudo reboot
