由于最近需要对接一台服务器的文件夹,由于内容较大,且实时在写,所以想到了远程挂载。这里使用了sshfs。
sshfs 安装：
centos：
yum install sshfs
ubuntu：
sudo apt-get install sshfs
使用说明：
sshfs –help
usage: sshfs [user@]host:[dir] mountpoint [options]general options:
-o opt,[opt…] mount options
-h –help print help
-V –version print versionSSHFS options:
-p PORT equivalent to ‘-o port=PORT’
-C equivalent to ‘-o compression=yes’
-F ssh_configfile specifies alternative ssh configuration file
-1 equivalent to ‘-o ssh_protocol=1’
-o reconnect reconnect to server
-o delay_connect delay connection to server
-o sshfs_sync synchronous writes
-o no_readahead synchronous reads (no speculative readahead)
-o sync_readdir synchronous readdir
-o sshfs_debug print some debugging information
-o cache=BOOL enable caching {yes,no} (default: yes)
-o cache_max_size=N sets the maximum size of the cache (default: 10000)
-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 cache_clean_interval=N
sets the interval for automatic cleaning of the
cache (default: 60)
-o cache_min_clean_interval=N
sets the interval for forced cleaning of the
cache if full (default: 5)
-o workaround=LIST colon separated list of workarounds
none no workarounds enabled
[no]rename fix renaming to existing file (default: off)
[no]truncate fix truncate for old servers (default: off)
[no]buflimit fix buffer fillup bug in server (default: on)
[no]fstat fix fstat for old servers (default: off)
-o idmap=TYPE user/group ID mapping (default: none)
none no translation of the ID space
user only translate UID/GID of connecting user
file translate UIDs/GIDs contained in uidfile/gidfile
-o uidfile=FILE file containing username:remote_uid mappings
-o gidfile=FILE file containing groupname:remote_gid mappings
-o nomap=TYPE with idmap=file, how to handle missing mappings
ignore don’t do any re-mapping
error return an error (default)
-o ssh_command=CMD execute CMD instead of ‘ssh’
-o ssh_protocol=N ssh protocol to use (default: 2)
-o sftp_server=SERV path to sftp server or subsystem (default: sftp)
-o directport=PORT directly connect to PORT bypassing ssh
-o slave communicate over stdin and stdout bypassing network
-o disable_hardlink link(2) will return with errno set to ENOSYS
-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)FUSE options:
-d -o debug enable debug output (implies -f)
-f foreground operation
-s disable multi-threaded operation-o allow_other allow access to other users
-o allow_root allow access to root
-o auto_unmount auto unmount on process termination
-o nonempty allow mounts over non-empty file/dir
-o default_permissions enable permission checking by kernel
-o fsname=NAME set filesystem name
-o subtype=NAME set filesystem type
-o large_read issue large read requests (2.4 only)
-o max_read=N set maximum size of read requests-o hard_remove immediate removal (don’t hide files)
-o use_ino let filesystem set inode numbers
-o readdir_ino try to fill in d_ino in readdir
-o direct_io use direct I/O
-o kernel_cache cache files in kernel
-o [no]auto_cache enable caching based on modification times (off)
-o umask=M set file permissions (octal)
-o uid=N set file owner
-o gid=N set file group
-o entry_timeout=T cache timeout for names (1.0s)
-o negative_timeout=T cache timeout for deleted names (0.0s)
-o attr_timeout=T cache timeout for attributes (1.0s)
-o ac_attr_timeout=T auto cache timeout for attributes (attr_timeout)
-o noforget never forget cached inodes
-o remember=T remember cached inodes for T seconds (0s)
-o intr allow requests to be interrupted
-o intr_signal=NUM signal to send on interrupt (10)
-o modules=M1[:M2…] names of modules to push onto filesystem stack-o max_write=N set maximum size of write requests
-o max_readahead=N set maximum readahead
-o max_background=N set number of maximum background requests
-o congestion_threshold=N set kernel’s congestion threshold
-o async_read perform reads asynchronously (default)
-o sync_read perform reads synchronously
-o atomic_o_trunc enable atomic open+truncate support
-o big_writes enable larger than 4kB writes
-o no_remote_lock disable remote file locking
-o no_remote_flock disable remote file locking (BSD)
-o no_remote_posix_lock disable remove file locking (POSIX)
-o [no_]splice_write use splice to write to the fuse device
-o [no_]splice_move move data while splicing to the fuse device
-o [no_]splice_read use splice to read from the fuse deviceModule options:
[iconv]
-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)[subdir]
-o subdir=DIR prepend this directory to all paths (mandatory)
-o [no]rellinks transform absolute symlinks to relative
默认使用方式：
1. 在本地创建挂载文件夹
mkdir -p /home/demofs/
挂载远端服务器
sshfs root@[remoteServer]:/home/fs/ /home/demofs/ 按照提示操作即可
问题：
由于远程服务用GBK方式进行的文件写入,服务器的默认编码又是UTF-8,在挂载之后发现文件乱码。
在仔细阅读文件之后。
最终命令方式
sshfs root@[remoteServer]:/home/fs/ /home/demofs/ -o reconnect ,modules=iconv,from_code=GBK,to_code=UTF-8
