linux – 如何为sshfs指定密钥文件？

概述我查看了sshfs –help,没有提到密钥文件.我的计算机上有多个pub / priv密钥对(针对不同的服务器),我想指定使用哪个密钥.我该怎么办？ usage: sshfs [user@]host:[dir] mountpoint [options] general options: -o opt,[opt...] mount options -h --help 我查看了sshfs –help,没有提到密钥文件.我的计算机上有多个pub / priv密钥对(针对不同的服务器),我想指定使用哪个密钥.我该怎么办？

解决方法 注意这个选项：

-o SSHOPT=VAL ssh options (see man ssh_config)

如果你看看man ssh_config,可以选择设置私钥文件的路径,名为IDentityfile,这样你就可以这样做：

sshfs -oIDentityfile=/abs/path/to/ID_rsa server: path/to/mnt/point

身份文件的路径必须是绝对路径.
