通过SSHFS在RHEL中安全的挂载远程Linux/UNIX目录或文件系统

You can easily mount remote server file system or your own home directory using special sshfs and fuse tools.

FUSE - Filesystem in Userspace

FUSE is a Linux kernel module also available for FreeBSD, OpenSolaris and Mac OS X that allows non-privileged users to create their own file systems without the need to write any kernel code. This is achieved by running the file system code in user space, while the FUSE module only provides a “bridge” to the actual kernel interfaces. FUSE was officially merged into the mainstream Linux kernel tree in kernel version 2.6.14.

You need to use SSHFS to access to a remote filesystem through SSH or even you can use Gmail account to store files.

Following instructions are tested on CentOS, Fedora Core and RHEL 4/5 only. But instructions should work with any other Linux distro without a problem.

Step # 1: Download and Install FUSE

Visit fuse home page and download latest source code tar ball. Use wget command to download fuse package:
# wget http://superb-west.dl.sourceforge.net/sourceforge/fuse/fuse-2.6.5.tar.gz
Untar source code:
# tar -zxvf fuse-2.6.5.tar.gz
Compile and Install fuse:
# cd fuse-2.6.5
# ./configure
# make
# make install


Step # 2: Configure Fuse shared libraries loading

You need to configure dynamic linker run time bindings using ldconfig command so that sshfs command can load shared libraries such as libfuse.so.2:
# vi /etc/ld.so.conf.d/fuse.conf
Append following path:
/usr/local/lib
Run ldconfig:
# ldconfig

Step # 3: Install sshfs

Now fuse is loaded and ready to use. Now you need sshfs to access and mount file system using ssh. Visit sshfs home page and download latest source code tar ball. Use wget command to download fuse package:
# wget http://easynews.dl.sourceforge.net/sourceforge/fuse/sshfs-fuse-1.7.tar.gz
Untar source code:
# tar -zxvf sshfs-fuse-1.7.tar.gz
Compile and Install fuse:
# cd sshfs-fuse-1.7
# ./configure
# make
# make install


Mounting your remote filesystem

Now you have working setup, all you need to do is mount a filesystem under Linux. First create a mount point:
# mkdir /mnt/remote
Now mount a remote server filesystem using sshfs command:
# sshfs [email protected]: /mnt/remote
Where,

• sshfs : SSHFS is a command name
• [email protected]: - vivek is ssh username and rock.nixcraft.in is my remote ssh server.
• /mnt/remote : a local mount point

When promoted supply vivek (ssh user) password. Make sure you replace username and hostname as per your requirements.

Now you can access your filesystem securely using Internet or your LAN/WAN:
# cd /mnt/remote
# ls
# cp -a /ftpdata . &


To unmount file system just type:
# fusermount -u /mnt/remote
or
# umount /mnt/remote
