Linux服务器上可以使用sshfs将远程文件系统映射到本地目录。使用起来更方便。

1.sshfs软件安装

Ubuntu

apt-get install sshfs -y

Fedore上安装

yum install fuse-sshfs -y

CentOS上安装

默认源无该工具，需要先安装EPEL源

yum install -y epel-release
yum -y install fuse-sshfs

2.挂载远程目录

如果你远程服务器设置了 key 登陆，那么 sshfs 也可以用这个私钥来实现免密登陆哦。指定证书登陆的参数是： -o IdentityFile=/root/.ssh/id_rsa.pub

完整的挂载命令就是：

sshfs -o allow_other,transform_symlinks -o IdentityFile=/root/.ssh/id_rsa.pub root@192.168.1.100:/data/backups /data/backups
