NFS(Network File System)
■ 분산 파일 시스템 : NFS(UNIX/LINUX), CIFS(WINDOWS)
(1) NFS 서버 데몬
NFS 서버는 언제든지 클라이언트가 마운트 할 수 있도록 준비 되어 있어야 하며 NFS는 rpc.mountd, rpc.nfsd 두 데 몬을 가지고 있다. rpc.mountd 데몬과 rpc.nfsd 데몬은 RPC 기반의 서비스이기 때문에, rpcbind(portmapper)가 반 드시 떠 있어야만 사용이 가능하다.
(2) NFS 관련 파일
■ /etc/exports (NFS Server)에서 부팅시에 공유하는 정보를 담는 파일
■ /etc/fstab (NFS Client)에서 부팅시에 마운트하는 정보를 담는 파일
(3) NFS 관련 명령어
■ exportfs 명령어 (NFS Server) 공유자원을 확인 할 때 사용하는 명령어
■ showmount 명령어 (NFS Client) 공유할 자원 확인 할 때 사용하는 명령어
■ mount 명령어 (NFS Client) 공유된 자원 마운트 할 때 사용하는 명령어
(3-1) exportfs 명령어
NFS 서버에서 공유된 자원을 확인 할 때 사용하는 명령어이다.
(명령어 형식)
# exportfs /* 공유된 자원 정보를 간략하게 보여준다. */
# exportfs -v /* 공유된 자원 정보를 자세하게 보여준다. */
# exportfs -ar /* 공유된 자원 목록(예: /etc/exports)을 다시 읽는다.(reread) */
■ NFS 서버에서 디렉토리 공유 방법
------------------------------------------
(첫번째 방법) # vi /etc/exports
/share *(rw)
# service nfs restart
------------------------------------------
(두번째 방법) # vi /etc/exports
/share *(rw)
# exportfs -ar
------------------------------------------
(3-2) showmount 명령어
NFS 서버의 공유된 자원을 확인할 때 사용한다.
(명령어 형식)
# showmount -e /* 로컬 서버에 공유된 자원 확인 */
# showmount -e 172.16.9.252 /* 원격 서버에 공유된 자원 확인 */
(3-3) mount 명령어
NFS 서버의 공유된 자원을 마운트 할 때 사용하는 명령어이다.
현재 마운트 할 때는 mount 명령어를 사용하고 부팅시에 마운트하기 위해서는 /etc/fstab 파일을 사용한다.
(명령어 형식)
# mount [-t nfs] nfs.linux.co.kr:/usr/local /usr/local
# mount [-t nfs] 172.16.9.2XX:/share /mnt/share
(4) NFS 서비스 제어
(현재서비스 제어)
# service nfs start /* NFS 서비스 start */
# service nfs stop /* NFS 서비스 stop */
# service nfs restart /* NFS 서비스 restart */
# service nfs status /* NFS 서비스 상태 확인 */
# service nfs reload /* NFS 설정 파일 다시 읽기(# exportfs –ar) */
(부팅시 서비스 제어)
# chkconfig nfs on (# chkconfig --level 35 nfs on)
# ntsysv (# setup)
# system-config-service (# serviceconf)
(NFS GUI 방식의 설정 툴)
# system-config-nfs &
# cat /etc/exports
# exportfs
3 NFS(Network File System) 서버 실습
■ root 사용자의 서버 자원 마운트
■ Man Page 서버 구축
■ Home Directory 서버 구축
■ 원격 CD 마운트
■ 원격 백업 서버 구축
■ (NFS Server/Client에서 UID/GID 퍼미션 관계)
==== NFS Server ===== ==== NFS Client =====
# vi /etc/exports # mount S:/share /p
/share/file1 <-- UID/GID check --> /p/file1
/share/dir1 /p/dir1
===================== ======================
/share/file1(rw-r--r-- user01 other) /p/file1(rw-r--r-- 500 1 )
user01(UID=500) A
|
|
user01 (# cd /p ; cat file1)
(UID=500)
/share/file1(rw-r--r-- root root) /p/file1(rw-r--r-- 0 0 )
root(UID=0) A
|
|
root (# cd /p ; cat file1)
(UID=0)
A
|
+---> (root(X) -> anonymous(nfsnobody))
[참고] no_root_squash 옵션(root_squash <----> no_root_squash)
NFS 서버에서 NFS 클라이언트의 root 사용자를 인정할 때 사용하는 공유 옵션이다.
(실무 예) Diskless Client(EX: Hardless Client)
Diskless Server (/disk/OS1) ------> Diskless Client(/)

(실무 예) Application Server
■ 노트북(window/vmware/linux(centos))
# rpm --root=/disk/app1 -ivh <PKG>.rpm
# vi /etc/exports
/disk *(rw)
# service nfs restart
■ 상용서버
# mkdir -p /mnt/app1
# mount IP:/disk /mnt/app1
(실무 예) 오락서버(EX: 리니지), 메일서버(EX: daum.net/naver.com)
오락서버(EX: 리니지)
10000 대(NFS 클라이언트)
- server1(/home/user01) NFS 서버(NAS)
- server2(/home/user01) (/export/home/user01)
- server3(/home/user01)
- server4(/home/user01)
- .....
(실무 예) 웹서버(EX: 이중화)
WEB1(/www)
WEB2(/www) NFS 서버(NAS) - /www
WEB3(/www)
[EX4] 원격서버의 CD 마운트
리눅스 서버에는 CD-ROM이 장착이 되지 않은 서버가 존재할 수 있다. 이런 경우, 다른 서버에 존재하는 CD-ROM에 CD를 장착하고 공유한후, 마운트 해서 사용하면 된다.
리눅스 서버에 CD-ROM이 고장난 경우
리눅스 서버중에 CD-ROM이 없는 서버의 경우
1. 네트워크 파일 서비스의 종류(Network File Service Type)
네트워크를 지원하는 수 많은 플랫폼들은 각각 자신의 플랫폼에 사용할 목적으로 다양한 파일 서비스 규격들을 만들어 냈다. 개별적인 플랫폼을 위해 만들어진 이러한 기술들은 자신의 플랫폼 내에서만 호환성을 가지고 있던 초기의 제한점을 넘어서 지금은 다양한 이기종의 플랫폼과 호환될 수 있는 형태로 확장되어 가고 있다.
네트워크 파일 서비스의 종류는 다음과 같다.
l NFS(Network File System)
l AFS(Andrew File System)
l NetWare
l Lan Manager
l Microsoft Network Service(CIFS)
l Apple Talk
Linux(NFS) | Windows(CIFS)

2. 삼바(SAMBA) 서버 개요
■ (서버)Linux <----- NFS -----> (클라이언트/서버)Linux/UNIX
■ (서버)Linux <----- CIFS/SMB -----> (클라이언트/서버)Windows
마이크로소프트에서는 SMB라는 이름보다는 좀 더 범위가 큰 CIFS(Common Internet File System)라는 프로토콜로 부른다. 이 프로토콜은 SMB 프로토콜에 Lan Manager, NetBIOS 프로토콜까지 포함한다.
삼바(SAMBA) 공식 사이트: http://www.samba.org
(1) 삼바(SAMBA)의 기능
SAMBA 기능은 유닉스/리눅스 플랫폼 환경에서 파일과 하드웨어(CD-ROM, Printer)를 서로 공유할 수 있게 해주는 프 로토콜이다. 이것을 정리해 보면 다음과 같다.
- 유닉스/리눅스 파티션과 윈도우와의 공유
- 윈도우 파티션과 유닉스/리눅스와의 공유
- 유닉스/리눅스의 프린터와 윈도우와의 공유
- 윈도우의 프린터와 유닉스와의 공유
(2) 삼바(SAMBA)의 활용
- 유닉스/리눅스 서버의 디렉토리를 MS 윈도우에서의 하나의 드라이브로 사용
- 프린터 공유
- 유닉스/리눅스 서버의 FTP 대치(EX: File Server)
- CD-ROM 데이터 공유
- 백업(Backup) 시스템으로 사용
3. 삼바(SAMBA) 서버
패키지: samba, samba-clinet, samba-common
----- Linux(SAMBA) Server ----- ----- Windows 7 Server -----
(linux2XX)
nmbd(137,138)
smbd(139)
- /etc/samba/smb.conf
------------------------------- ----------------------------
ㅇ nmbd(NetBIOS Name Server)
- 자원 검색(Resource Browing)
- WINS 서버 관리(WINS Server)
ㅇ smbd(SMB/CIFS Server)
- 인증/인가 관리(Authentication and Authorization)
- 파일/프린터 공유 관리(File and Printer Sharing)
* SMB(오픈버전) = CIFS(라이센스버전)
4. 삼바(SAMBA) 관련 명령어
■ smbclient 명령어
■ smbstatus 명령어
■ testparm 명령어
■ mount.cifs/umount.cifs 명령어

Each IMAP server has its own quirks. As much as we tried to stick
to standards, it doesn't help much if the IMAP server doesn't follow
the same principles. We have made some work-arounds for some of
these servers. If you would like to use them, please select your
IMAP server. If you do not wish to use these work-arounds, you can
set this to "other", and none will be used.
cyrus = Cyrus IMAP server
uw = University of Washington's IMAP server
exchange = Microsoft Exchange IMAP server
courier = Courier IMAP server
macosx = Mac OS X Mailserver
hmailserver = hMailServer
other = Not one of the above servers

[참고] (다른 방법) 윈도우(Windows XP) 공유 자원을 리눅스(Linux CentOS 5.4)에서 접근 하기
(두번째 방법) 바탕화면에서 확인하기
-> "root's Home" 아이콘 더블클릭
-> 새로 뜬 'root' 창에서 'File' 부분 선택
-> "Connect to Server" 선택
-> 새로 뜬 "Connect to Server" 창에서
Service type : "Windows share" 선택
Server : <자신 윈도우 서버의 이름> (예) 172.16.9.X
-> 공유된 자원이 보일것이다.
바탕화면에 아이콘으로 생성된다.
다음부터는 바탕화면의 아이콘 클릭하면 된다.

[참고] 부팅시에 SMB 마운트(리눅스 서버에 공유된 자원을 윈도우에서 부팅시에 마운트)
(Windows 쪽에서) "네트워크 드라이브 연결"을 사용
윈도우(Windows XP) 서버에서 네트워크 연결이 되면 자동으로 리눅스 서버(삼바 서버)의 자원을 마운트 할 수 있도록 하기 위해서는 "네트워크 드라이브 연결"을 사용한다.

(Linux 쪽에서) /etc/fstab 파일 사용
