Mac下挂载远程目录到本地

挂载远程目录到本地，目的是希望能够跟查看本地文件一样，可以方便地浏览远程目录下的文件。

sshfs就是能够满足这项需求的程序，不仅适用于ubuntu/centos等linux系统，也同样适用于Mac.

使用brew安装sshfs

brew install sshfs

brew下Mac下最常见的套件管理工具,如果你的电脑没有安装该程序,请参考Homebrew进行安装.

上面过程中,你可能会遇到如下的提示:

只需要按照提示一步一步操作即可.

先执行brew cask install osxfuse. 该过程实际上是去github下载安装osxfuse.dmg.

安装好osxfuse后，按照提示需要重启电脑(不过我试过了，不重启电脑也是可以的)。

再重新执行brew install sshfs.

安装sshfs结束后,就可以使用sshfs挂载远程目录到本地：

sshfs -C -o reconnect <user>@<host>:<remote_dir> <local_dir>

比如,我想要将远程主机192.168.1.101上的/mnt/images/目录，挂载到本地~/Desktop/images/目录下。过程中使用root账号登陆.

sshfs -C -o reconnect root@192.168.1.101:/mnt/images/ ~/Desktop/images/

如果ssh不是默认的22端口,则还需要带上选项: -p <端口号>

挂载到本地时, 请避免挂载在根目录，或者当前角色的主目录下, 会报错。比如如下的错误操作:

mkdir ~/ImageFolder
sshfs -C -o reconnect root@192.168.1.101:/mnt/images/ ~/ImageFolder/

会看到错误提示:

mount_osxfuse: mount point /Users/xxxx/ImageFolder is itself on a OSXFUSE volume
fuse: failed to mount file system: Invalid argument

This question is answered on https://serverfault.com/questions/6709/sshfs-mount-that-survives-disconnect/639735. I am duplicating it here.

sshfs -o reconnect,ServerAliveInterval=15,ServerAliveCountMax=3 server:/path/to/mount

As explained at the Server Fault link, the ServerAliveInterval=15 option asked sshfs to check if the server is alive every 15 seconds. ServerAliveCountMax=3 allows the server to not respond for up to three alive checks. The result is that if the server is unavailable for 1 minute, sshfs will reconnect to the server.

重启断网休眠之后remount：

You simply need to unmount the sshfs volume. Try running

umount /Users/xxxx/ImageFolder 

in Terminal. You can get a list of all mounts by running

mount

in Terminal.
