简单好用的sshfs — 通过ssh映射远程路径

来自 http://wendal.net/457.html

最近习惯性访问N个Linux机器,在不同机器间跳来跳去,很是麻烦,最终,找到了sshfs,可以把远程目录直接映射到本地,无需修改远程机器的设置,仅要求有ssh连接的权限

官网地址: http://fuse.sourceforge.net/sshfs.html

安装:

#如果是ubuntu
apt-get install sshfs
#如果是Fedore
yum install fuse-sshfs
#如果是CentOS,貌似只能自己安装了
wget http://nchc.dl.sourceforge.net/project/fuse/sshfs-fuse/2.4/sshfs-fuse-2.4.tar.gz
tar xvf sshfs-fuse-2.4.tar.gz
cd sshfs-fuse-2.4
./configure
#如果缺glib2什么的,就自行装上
make install

先看看选项:

general options:
    -o opt,[opt...]        mount options
    -h   --help            print help
    -V   --version         print version

SSHFS options:
    -p PORT                equivalent to '-o port=PORT'
    -C                     equivalent to '-o compression=yes' #启用压缩,建议配上
    -F ssh_configfile      specifies alternative ssh configuration file #使用非默认的ssh配置文件
    -1                     equivalent to '-o ssh_protocol=1' #不要用啊
    -o reconnect           reconnect to server               #自动重连
    -o delay_connect       delay connection to server
    -o sshfs_sync          synchronous writes
    -o no_readahead        synchronous reads (no speculative readahead) #提前预读
    -o sshfs_debug         print some debugging information
    -o cache=BOOL          enable caching {yes,no} (default: yes) #能缓存目录结构之类的信息
    -o cache_timeout=N     sets timeout for caches in seconds (default: 20)
    -o cache_X_timeout=N   sets timeout for {stat,dir,link} cache
    -o workaround=LIST     colon separated list of workarounds
             none             no workarounds enabled
             all              all workarounds enabled
             [no]rename       fix renaming to existing file (default: off)
             [no]nodelaysrv   set nodelay tcp flag in sshd (default: off)
             [no]truncate     fix truncate for old servers (default: off)
             [no]buflimit     fix buffer fillup bug in server (default: on)
    -o idmap=TYPE          user/group ID mapping, possible types are:  #文件权限uid/gid映射关系
             none             no translation of the ID space (default)
             user             only translate UID of connecting user
    -o ssh_command=CMD     execute CMD instead of 'ssh'
    -o ssh_protocol=N      ssh protocol to use (default: 2) #肯定要2的
    -o sftp_server=SERV    path to sftp server or subsystem (default: sftp)
    -o directport=PORT     directly connect to PORT bypassing ssh
    -o transform_symlinks  transform absolute symlinks to relative
    -o follow_symlinks     follow symlinks on the server
    -o no_check_root       don't check for existence of 'dir' on server
    -o password_stdin      read password from stdin (only for pam_mount)
    -o SSHOPT=VAL          ssh options (see man ssh_config)

Module options:

[subdir]
    -o subdir=DIR	    prepend this directory to all paths (mandatory)
    -o [no]rellinks	    transform absolute symlinks to relative

[iconv]
    #字符集转换,对我这种UTF8控,默认已经是最好的
    -o from_code=CHARSET   original encoding of file names (default: UTF-8)
    -o to_code=CHARSET	    new encoding of the file names (default: UTF-8)

实际使用:

挂载(如果配上ssh key就可以完全自动化了):
sshfs [email protected]:/opt /opt/s109
卸载:
fusermount -u /opt/s109
