Ubuntu - sshfs 远程服务器目录挂载工具

Github - libfuse/sshfs

SSHFS(SSH Filesystem) 是一种采用 SFTP(普通 SSH) 连接来挂载远程服务器或工作站上的目录和文件交互的工具. 一般情况下,大部分 SSH 服务器支持 SFTP 访问.

1. 使用场景

[1] - 本机访问远程服务器目录与文件;

[2] - 多台服务器之间目录与文件的访问.

Ubuntu - 挂载 NFS 服务器的文件系统到本机 - AIUAI 挂载服务器所分享的目录.

2. Ubuntu 安装

[1] - Ubuntu apt 安装:

sudo apt-get install sshfs

版本可能比较早,如:

sshfs --version
#SSHFS version 2.5
#FUSE library version: 2.9.4
#fusermount version: 2.9.4
#using FUSE kernel interface version 7.19

[2] - 源码安装

#下载最新源码
#https://github.com/libfuse/sshfs/releases
wget https://github.com/libfuse/sshfs/releases/download/sshfs-3.5.2/sshfs-3.5.2.tar.xz
#解压
tar xvf sshfs-3.5.2.tar.xz

#编译安装推荐采用 Meson>0.38 和 Ninja
#http://mesonbuild.com/
#https://ninja-build.org/

cd sshfs-3.5.2
mkdir build 
cd build
#默认参数进行编译
meson ..

#修改编译参数
mesonconf                  # list options
mesonconf -D strip=true    # set an option

#安装
ninja
python3 -m pytest test/    # optional, but recommended
sudo ninja install

或者可以试试:

wget https://github.com/libfuse/sshfs/archive/sshfs-3.5.2.zip
unzip sshfs-3.5.2.zip

cd sshfs-3.5.2
./configure
make -j4
make install 

3. 使用方法

3.1. 远程(mount)服务器目录挂载

sshfs [user@]hostname:[directory] mountpoint
sshfs [服务器用户名]@服务器ip地址:[挂载目录] [本地挂载点]

#如:
sshfs username@192.168.1.10:/path/to/test/ mountpoint  

(1) - 推荐不采用 root 用户使用 SSHFS. 挂载的目标位置必须是属于 user 的.

(2) - 如果 user 参数忽略,SSHFS 会使用本地用户名(local username).

(3) - 如果 directory 参数忽略,SSHFS 会使用远程服务器的 home 目录路径.

(4) - 类似于 SSH, SSHFS 可能要求输入密码.

3.2. 挂载时自动输入密码

如:

sshfs -o ssh_command='sshpass -p 123456 ssh' -o cache=yes, allow_other [user@]hostname mountpoint

3.3. 卸载(unmont)服务器目录(文件系统)

fusermount -u mountpoint

3.4. 查看 sshfs 参数

sshfs --help

如:

通用参数:
    -o opt,[opt...]        mount options
    -h   --help            print help
    -V   --version         print version
