NFS - 파일이나 백업용 서버로 많이씀
mountd Daemon , NFS Server Daemon (NFSD) : 공유해주는 서버
file handle : server에 있는 파일이나 디렉토리 식별
/etc/dfs/dfstab : 공유내역 저장하는 파일

server 역할

vi /etc/dfs/dfstab

• share -o ro /usr/share/man 이나
• share -o rw /usr/share/man 이나
• share -o root /usr/share/man 수정

/etc/init.d/nfs.server start - daemon 시작
share - 공유디렉토리 확인
dfshare - 공유되있는 디렉토리 리스트 확인
dfmounts - 공유되있는 사용자 리스트 확인

client 역할

mv /usr/share/man /usr/share/men -man을 men으로 이름변경
man ls -man있는지 확인
mkdir /usr/share/man -man디렉토리 생성
mount server104/usr/share/man /usr/share/man -server104의 /usr/share/man으로 mount
man ls -man확인
mount -마운트확인
dfmounts server104 -server104에 연결되어있는지 마운트 확인
umount /usr/share/man -마운트해제
dfmounts server104 -server104에 연결되어있는지 마운트 확인

문제풀기

1. server2 에 100m 디스크 추가 후 /data로 마운트 하세요
2. server2 의 /data를 읽기/쓰기가 가능하도록 공유하세요
3. server1에서 server2의 /data를 /server1/backup으로 NFS연결하세요
4. server1에서 /etc/ssh 디렉토리를 /server1/backup/ssh_backup.tar.zip으로 백업하세요

---

server2의 역할

touch reconfigure
init 6
100mb 디스크생성
format 파티션설정
100m 디스크추가

---

newfs dev/rdsk/c1d1s0 -포맷
mount dev/dsk/c1d1s0 -마운트
vi /etc/dfs/dfstab -/data를 읽기/쓰기 가능하도록 설정
share -o root=server104:server105 /data -공유 설정
/etc/init.d/nfs.server stop -server stop
/etc/init.d/nfs.server stop -server start

server1의 역할

mkdir -p /server1/backup -디렉토리생성
mount server104:/data /server1/backup -server1/backup을 server104의 data로 마운트
cd /server1/backup -경로이동
tar cvf /server1/backup/ssh_backup.tar.zip /etc/ssh/* -ssh_backup.tar.zip 으로 압축
cp ssh_backup.tar.zip /data1 -data1로 백업
