#                                                             SSH免密登录 #

### 1、客户端生成公钥、私钥 ###

yang@yang MINGW64 ~
    $ cd ~     //进入家目录
    
    yang@yang MINGW64 ~
    $ rm -r .ssh                             //删除原先的目录.ssh
    rm: cannot remove '.ssh': No such file or directory
    
    yang@yang MINGW64 ~
    $ ssh-keygen -t rsa -C 907486852@qq.com                         //生成公钥、私钥
    Generating public/private rsa key pair.
    Enter file in which to save the key (/c/Users/yang/.ssh/id_rsa):
    Created directory '/c/Users/yang/.ssh'.
    Enter passphrase (empty for no passphrase):
    Enter same passphrase again:
    Your identification has been saved in /c/Users/yang/.ssh/id_rsa.
    Your public key has been saved in /c/Users/yang/.ssh/id_rsa.pub.
    The key fingerprint is:
    SHA256:pPSUKaoux0qw9t66ynPdkt2FOn0vNISfZx+v6H5MAIE 907486852@qq.com
    The key's randomart image is:
    +---[RSA 2048]----+
