SHFS - 원격 디렉토리 마운트 사용 방법

SSHFS는 서버나 워크스테이션에 위치한 디렉토리와 파일을 SSH 연결을 통해 클라이언트가 마운트하고 통신할 수 

있게 하는 파일 시스템이다.

SSHFS는 SFTP를 사용하기 때문에 서버와 클라이언트 간에 전송된 모든 데이터를 암호화하고 암호를 해독해야 하며, 

이로 인해 NFS에 비해 성능이 약간 저하되고 클라이언트 및 서버의 CPU 사용량이 증가한다.

 

1. SSHFS 설치

# UBUNTU
apt install sshfs

# RedHat기반의 Linux
yum install sshfs

# Mac
brew cask install osxfuse
brew install sshfs

# Windows
WinFsp, SSHFS-WIN 두개의 패키지 설치

 

2. 원격 파일 시스템 마운트

sshfs [user@]host:[remote_directory] mountpoint [options]

2-1 마운트 디렉토리 생성 및 원격디렉토리 연동

# 마운트 디렉토리생성
mkdir /temp

# 원격 디렉토리 연동
sshfs demo@192.168.10.121:/twins/temp /temp

마운트시 사용자의 비밀번호를 입력하라고 나오면 암호를 입력 하면 된다.

만약 디렉터리를 마운트 할 때마다 암호를 입력하지 않으려면  SSH키를 생성하고 암호없는 SSH로그인을 설정하면 된다.

2.2 SSH public key 생성

$root@q381-1921:/# ssh-keygen

Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa
Your public key has been saved in /root/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:/a3uBy9NYgx3isDrVnCUEH9pK+oYOM4NygJIBCDz+WY root@q381-1921
The key`s randomart image is:
+---[RSA 3072]----+
|B       oo .     |
|.+ .     .o  .   |
|. o    . .. +    |
| . .    +.oo...  |
|o   E   S=o=.o   |
|o  o .  ..oo*..  |
|.   + .... ..*.  |
|.. + + +o   ..+  |
| .o o o..  o+o   |
+----[SHA256]-----+

$root@q381-1921:/# ls ~/.ssh/id_*
/root/.ssh/id_rsa  /root/.ssh/id_rsa.pub

$root@q381-1921:/# ssh-copy-id root@접속할 아이피
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
The authenticity of host '1.1.1.1 (1.1.1.1)' can`t be established.
ED25519 key fingerprint is SHA256:3LnG/lLjiytuDCvdn2Eh4qfaadjv69wLiWnnnvYBtQQ.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
$root@183.111.64.4`s password:*********

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'root@1.1.1.1'"
and check to make sure that only the key(s) you wanted were added.

 

 

 

3. 원격 디렉토리 마운트

$ vi /etc/fstab

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda2 during curtin installation

/swap.img       none    swap    sw      0       0
demo@192.168.10.121:/twins/temp /temp  fuse.sshfs  defaults,IdentityFile=/home/twins/.ssh/id_rsa,_netdev,delay_connect,allow_other,uid=1000,gid=1000    0     0

:wq

$ mount --all

 

4. 마운트 해제

unmout /temp
