RHEL4+Oracle10g+Rac_ASM (Node1_Node2 설정)

1. Node1 설정

# ifconfig 로 ip확인

# netstat -nr 로 gateway 주소 확인

# neat 로 ip 설정

eth0 , eth1 edit버튼으로 ip변경

DNS주소는 168.126.63.1

# /etc/init.d/network restart 로 네트워크 재시작

# ping 168.126.63.1 연결 잘 되어있는지 확인

vi /etc/hosts

Node 1 설정 끝  init 0 종료

2. Node2 설정

rac1 디렉토리에 있는 rac1.vmdk 파일과 rac1.vmx 파일을 rac2 디렉토리로 복사

rac1.vmx 파일을 아래와 같이 편집

vmware로 rac2디렉토리에 있는 rac1.vmx파일 열어서 실행

I copied it 선택

Space

Remove Configuration 두번 반복

Configure 선택 (2번 반복)

Use dynamic IP configuration 선택

터미널창 열어서 neat로 IP설정

# vi /home/oracle/.bash_profile 

export ORACLE_SID = rac1 -> export ORACLE_SID = rac2 로 바꿔주기

Node2 설정 끝 reboot

3. equivalence 설정

Node1,Node2 둘다 실행 (oracle 계정)

$ mkdir .ssh

$ ssh-keygen –t rsa

$ ssh-keygen –t dsa

Node1 만 실행

$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

$ ssh rac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

$ ssh rac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

$ scp ~/.ssh/authorized_keys rac2:~/.ssh/authorized_keys

Node1, Node2 모두 실행 

$ ssh rac1 date

$ ssh rac1-priv date

$ ssh rac2 date

$ ssh rac2-priv date
