초기에 추가한 디스크를 파티션해준다.
[root@rac1 ~]# fdisk /dev/sdb
The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-1305, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-1305, default 1305):
Using default value 1305
Command (m for help): t
Selected partition 1
Hex code (type L to list codes): 8e
Changed system type of partition 1 to 8e (Linux LVM)
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
n : 새로생성
p : 파티션
1 : 주 파티션 번호
시작실린더번호 : 엔터(자동으로 잡아줌)
용량지정 : 엔터(남은용량 전부 할당)
t : 타입지정
8e : Linux LVM용으로 파티션을 생성
w : 새로 생성한 파티션 저장
w 전에 p를 입력하면 파티션 옵션을 준 것을 볼 수 있다. 그 다음에 w로 저장해도 됨
같은 방법으로
[root@rac1 ~]# fdisk /dev/sdc
[root@rac1 ~]# fdisk /dev/sdd
해준다.
안해도 되는 작업이지만 내가 파티션을 잘 줬는지 궁금하다면
아래에 장치명 뒤에 숫자 1이 있는 것을 볼 수 있다.
그러면 파티션이 잘 된 것이다.

raw/*:oracle:dba:0660
oracle:dba으로 수정해준다.
퍼미션을 설정한 후 적용하기 위해서 다시 rawdevices를 재실행해준다.

권한이 변경되었는지 확인을 해준다.
oracle dba로 변경되었다.

노드1 세팅이 완료되었다.
노드1 리눅스를 init0으로 완전히 종료하고 난 다음
노드2를 세팅해준다.
rac2 폴더를 만든다.
rac1이 설치 된 폴더에 들어가서 ra1.vmdk, rac1.vmx를 복사한 후 붙여넣기를 해준다.
vmware의 상단메뉴 file-open 클릭해서 rac1.vmx 파일을 오픈한다.
devices 정보 위에 Edit virtual machine settings를 클릭한 후
options 탭을 클릭한다.
오른쪽에 있는 virtual machine name을 rac2로 고친다.
rac2 폴더 안에 있는 rac1.vmx 파일을 열어서 이름을 수정해준다.
displayName = "rac2"
(이건 위 작업을 했으면 변경되어 있을 것이다.
귀찮으면 그냥 vmx 파일을 열어서 1을 이 세 줄만 끝에 숫자를 2로 변경해주면 된다.)
nvram = "rac2.nvram"
extendedConfigFile = "rac2.vmxf"
1을 2로 변경해주고 저장해준다.
power on 그리고 rac2를 실행한다.
그럼 옮길 건지 I moved it 복사할 건지 i copied it 물어본다.
우리는 I copied it을 선택한다.
리눅스 화면 중 파란색 배경의 하드웨어 설정창이 뜨면 아무키나 누른다.
1 설정삭제
2 설정삭제
3 설정-동적 ip 자동할당 스페이스바(별표)로 확인
아래 화살표로 이동 확인
4 설정-동적 ip 자동할당 스페이스바(별표)로 확인
아래 화살표로 이동 확인
노드2에 root로 접속한다.
neat를 실행해서 네트워크 주소를 설정해준다.
노드1에서 해줬던 /etc/hosts에 있는 ip를 정보를 기준으로 변경해준다.
[root@rac1 ~]# neat
eth0 더블클릭 - 정적으로 설정된 ip주소 클릭
주소
서브넷마스크
기본게이트웨이주소 입력
eth1 더블클릭 - 정적으로 설정된 ip주소 클릭
주2
서브넷마스크 입력
상단의 탭 dns에서
호스트명 rac2로 변경
기본 dns : 168.126.63.1
[root@rac1 ~]# vi /home/oracle/.bash_profile
export ORACLE_SID=rac2 로 숫자를 변경해준다.
네트워크를 재시작 해준다.
[root@rac1 ~]# /etc/init.d/network restart
패킷을 보낼 수 있는지 확인한다.
[root@rac1 ~]# ping 168.126.63.1
ctrl + c 해서 보낸 것을 확인한다??
이거 안되도 상관이 없다.
/etc/hosts에 값을 모두 입력한 다음에 실행하면 정상적으로 되는듯하다.
이건 확인해볼 것 설치하는데 그리 중요하지 않은거같은데;;;
[root@rac1 ~]# vi /etc/sysconfig/network
HOSTNAME=rac2 로 변경을 해준다.
종료하고 노드1, 노드2 모두 oracle 계정으로 로그인함
어떤 건 노드1,2에 설치하든 상관없는데 스크립트 실행이라던가
특별히 노드1에서만 하는 작업이 있기때문에 신경써서 작업을 하자.
노드1, 노드2 공통작업
노드1
ssh-keygen -t rsa
ssh-keygen -t dsa
공통적으로 두 작업 다음에는 모두 엔터를 세번 입력하면 된다.
