Ubuntu 16.04 nfs 서버 설정
1. 서버 프로그램 설치
root@com1:~# apt-get install nfs-common nfs-kernel-server portmap
2. 서버 설정root@com1:/home# vi /etc/exports
/home/nfs 192.168.9.* (rw,no_root_squash,async)
폴더경로 허용 IP (권한)
3. nfs 옵션
ro : read only mount
rw : read/write mount
no_root_squash : nfs 서버와 클라이언트의 root 사용자를 같도록 설정
no_all_squash : root 이외 모든 사용자에 대해 똑깥은 UID 를 가진 사용자는 동일한 권한
sync : 서버와 클라이언트 사이에 sync (서버에 데이터가 저장되었는지 확인)
async : sync 옵션 미사용 (성능상으로는 향상)
no_subtree_check (파티션 전체를 nfs 설정한 경우 전송율 상승)
4. 서비스 재시작
root@com1:/home# systemctl restart nfs-kernel-server
root@com1:/home# systemctl restart portmap
