우선 Server 패키지를 설치해야 한다.

$ sudo apt-get install nfs-kernel-server nfs-common rpcbind

제공해줄 디렉토리를 하나 생성

$ mkdir NFS_VI

/etc/exports 파일을 수정한다.

설정을 모두 마쳤으면, 재시작!

$ sudo service nfs-kernel-server restart

NFS를 사용하기 위해서 사용하는 포트가 지정된 1개가 아니다. 그러다보니 방화벽 환경에서 NFS를 사용하게 되면 당연히 문제가 발생한다. 지금 사용하고 있는 port 현황을 확인해보도록 하자.

사용할 포트를 등록해보자.

/etc/services 파일을 수정한다.

...
status            4000/tcp                       # rpc.statd tcp port
status            4000/udp                       # rpc.statd udp port
mountd            4002/tcp                       # mountd tcp port
mountd            4002/udp                       # mountd udp port
rquotad           4003/tcp                       # rpc.rquotad tcp port
rquotad           4003/udp                       # rpc.rquotad udp port
...

실행 옵션도 수정해주어야 한다.

/etc/default/nfs-kernel-server 파일 수정

...
# RPCMOUNTDOPTS=""
RPCMOUNTDOPTS="-p 4002 -g"
...

다음의 파일을 수정해야 한다. 만약 없는 경우 새로 생성하면 된다.

/etc/modprobe.d/options.conf

options lockd nlm_udpport=4001 nlm_tcpport=4001

그리고, 이젠 서비스를 재시작하자.

$ sudo service rpcbind restart
$ sudo service nfs-kernel-server restart

이렇게 설정하게 되면 나의 경우

/home/stephanos/NFS_VI

이 폴더가 Network File System으로 연결 된다.

내가 현재 사용중인 NFS_VI 폴더를 묶은 파일 이다.

nfs_vi.tar

SVN 에 올라온 uboot를 컴파일 해서 올리고

==>printenv

해보면 커맨드들이 나온다.

run ???? 의 형태로 이를 실행 시키면 된다.

그대로 설정을 사용하고 server의 설정을 맞추던지 아니면 uboot의 설정을 변경해서 사용하면 된다.

나의 경우 아래와 같이 uboot의 설정을 변경해서 사용했다. 부팅시 로그 이다.
