sshfs远程挂载

 

1 2 3 4 5

#常用命令 sshfs -o nonempty,reconnect,allow_other,exec -p22 zjy@172.21.0.10:/data/zjy /data/zjy   cat /etc/fstab sshfs#zjy@172.21.0.10:/data/zjy /data/zjy fuse nonempty,reconnect,allow_other,exec 0 0

一、什么是 SSHFS
SSHFS(Secure SHell FileSystem)是一个客户端,可以让我们通过 SSH 文件传输协议(SFTP)挂载远程的文件系统并且在本地机器上和远程的目录和文件进行交互。

1 2 3 4 5

centos： yum install sshfs   ubuntu： sudo apt-get install sshfs

二、准备两台任意操作系统

1 2 3 4 5

一台 mkdir   /test/zjy/      另一台 mkdir   /test/zjy/

三、挂载

1 2	sudo sshfs -o nonempty,allow_other,exec   root@xx.xx.xx.xx:/test/zjy/ /test/zjy/                        参数                用户@地址:挂载到               挂载到

nonempty 允许安装在非空文件/DIR上
allow_other 允许访问其他用户

mount -a       重新加载挂载信息

四、查看

1 2 3 4 5 6 7 8 9 10 11 12 13

查看当前系统挂载： [root@xiaoyuer ~]# cat /etc/mtab /dev/vda1 / ext3 rw,noatime,acl,user_xattr 0 0 proc /proc proc rw 0 0 sysfs /sys sysfs rw 0 0 devpts /dev/pts devpts rw,mode=0620,gid=5 0 0 none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0 root@192.168.1.121:/test/ /test/zjy fuse.sshfs rw,nosuid,nodev,allow_other 0 0       添加到自动挂载： root@192.168.1.121:/test/ /test/zjy fuse.sshfs rw,nosuid,nodev,allow_other 0 0

五、卸载命令

1	umount -f /test/zjy/

六、如果想免秘钥（可以做ssh免秘钥）

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

1.ssh免秘钥登录/挂载：   ssh-keygen -t rsa             [root@xiaoyuer ~]# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: b0:9d:41:56:b5:c4:b2:0e:0d:47:07:4d:fa:4c:47:03 root@xiaoyuer The key's randomart image is: +--[ RSA 2048]----+ |        oo+*E.o  | |       o. o+oo . | |      . .+.oo .  | |       +.oo+ .   | |      . So  o    | |          .      | |                 | |                 | |                 | +-----------------+   2.把公钥复制到服务器上   ssh-copy-id -i ~/.ssh/id_rsa.pub root@xx.xx.xx.xx   [root@xiaoyuer ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.1.121 root@192.168.1.121's password: Now try logging into the machine, with "ssh 'root@192.168.1.121'", and check in:     .ssh/authorized_keys   to make sure we haven't added extra keys that you weren't expecting.     3.测试 [root@xiaoyuer ~]# ssh root@xx.xx.xx.xx     测试成功在挂载就不需要数据密码<em id="__mceDel" style=" font-family: "PingFang SC", "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 14px">　</em>
