使用sshfs挂载远程文件系统

1|0什么是sshfs

ssfhs是一个客户端，可以让我们通过SFTP（SSH文件传输协议）挂载远程的文件系统，从而实现本机和远程的文件系统的交互

2|0安装sshfs

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

3|0有密码挂载远程文件系统

[root@localhost opt]# sshfs root@192.168.0.126:/opt share/   #将远程的/opt目录挂载在本机的share目录下，注意本机的share要是空目录
root@192.168.0.126's password:     #这种情况下要输入密码

4|0无密码挂载远程文件系统

1.生成rsa公钥

[root@localhost opt]# ssh-keygen -t rsa    #一路回车生成id_rsa.pub公钥
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.   #公钥路径
The key fingerprint is:
SHA256:rQhwm//R5d70BBiyZ/fm8Z2y++4aa9AQhjkKnK07sKY root@localhost.localdomain
The key's randomart image is:
+---[RSA 2048]----+
|    . o   o      |
|     + . + o     |
|  . . o . + o    |
|   + + . . + o   |
|    * . S o B o  |
|   o = . o * o o |
|  o   + o . o...+|
| E     . . . =o==|
|        .   o=X==|
+----[SHA256]-----+

2.将公钥复制到服务器上，期间会输入密码一次

[root@localhost opt]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.0.126   
usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@192.168.0.126's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'root@192.168.0.126'"
and check to make sure that only the key(s) you wanted were added.

3.然后再挂载，就不会输入密码

[root@localhost share]# sshfs root@192.168.0.126:/opt/pyexecnetcache/APP_AutoTest/allure_reports ../share/

5|0查看挂载点

[root@localhost share]# df -hT

6|0卸载挂载点

[root@localhost opt]# umount share/
