RAC 구성하기(solaris 10, oracle 10g) #3 ; 스토리지설정 및 node2 설정, equivalance 설정

0. openfiler는 계속 켜져있어야합니다.
1. node1(rac1)을 부팅합니다.
2. 스토리지 설정

3. 디스크세팅
# format
Specify disk (enter its number): 디스크선택
(경로에 openfiler가 있는 디스크는 모두 작업해야합니다.)

디스크 선택 후
format> fdisk

y 입력

format> part
partition> 0
Enter partition id tag[unassigned]: 엔터
Enter partition permission flags[wm]: 엔터
Enter new starting cyl[0]: 3  (0이나 엔터를 입력하게 되면, clusterware설치가 불가능합니다.)
Enter partition size[0b, 0c, 3e, 0.00mb, 0.00gb]: $
partition> label
Ready to label disk, continue? y
partition> quit
format> disk
디스크 선택
이후 모든 openfiler가 있는 디스크를 동일하게 작업하세요

4. power off 하고 노드2 만들기
# init 0 (셧다운)
이후 

이후 노드2를 부팅합니다. 추가적으로 뜨는 메시지에서는 I copied it.을 선택하세요.


5. 노드2 셋팅
5.1 IP재설정
5.1.1 이전상태확인
# ifconfig -a
lo0: flags=2001000849 mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=4001000842 mtu 1500 i ndex 2
inet 192.168.0.20 netmask ffffff00 broadcast 192.168.0.255
ether 0:c:29:5d:f8:1b
e1000g1: flags=1000842 mtu 1500 index 3
inet 0.0.0.0 netmask 0
ether 0:c:29:5d:f8:25

e1000g0, e1000g1을 변경합니다.

5.1.2 hostname 변경 및 네크워크카드설정
vi /etc/nodename
rac2

vi /etc/hostname.e1000g0
rac2

vi /etc/hostname.e1000g1
rac2-priv

5.1.3 네트워크카드 IP 설정
for host IP
ifconfig e1000g0 down
ifconfig e1000g0 unplumb
ifconfig e1000g0 plumb 192.168.0.21 up
ifconfig e1000g0 netmask 255.255.255.0 broadcast + up

for private IP
ifconfig e1000g1 down
ifconfig e1000g1 unplumb
ifconfig e1000g1 plumb 192.168.79.151 up
ifconfig e1000g1 netmask 255.255.255.0 broadcast + up

5.1.4 리붓 후 변경확인
# ifconfig -a
lo0: flags=2001000849 mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843 mtu 1500 index 2
inet 192.168.0.21 netmask ffffff00 broadcast 192.168.0.255
ether 0:c:29:4e:e5:c7
e1000g1: flags=1000843 mtu 1500 index 3
inet 192.168.79.151 netmask ffffff00 broadcast 192.168.79.255
ether 0:c:29:4e:e5:d1

5.2 oracle의 .profile 수정
export ORACLE_SID=rac2

$ hostname
rac2
$ vi .profile
export ORACLE_SID=rac2

5.3 iSCSI에 접근가능한지 확인하기
(따로 안해도 됩니다. list를 살펴보고 안되면 2.스토리지설정 부분을 다시 해주세요)


6. equivalance 설정
두 노드 모두 킨 후 oracle 유저에서 작업하세요.
한행씩 실행하세요

모든노드
mkdir .ssh
ssh-keygen -t rsa (실행 후 엔터3번)
ssh-keygen -t dsa  (실행 후 엔터3번) 

노드1에서만
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

모든노드

exec ssh-agent $SHELL   << ./runInstaller 설치하기 전에 한번 실행해주세요.
ssh-add  

ssh rac1 date
ssh rac1-priv date
ssh rac2 date
ssh rac2-priv date
(위 date명령들을 실행했을때, 비밀번호를 묻지않아야 합니다. known list관련 메시지는 상관없음)
