证书生成

• 生成

C:\Users\qbit\.ssh>ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (C:\Users\qbit/.ssh/id_rsa): qbit_rsa
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in qbit_rsa.
Your public key has been saved in qbit_rsa.pub.
The key fingerprint is:
SHA256:N+DzINKI2Sua4p3VP8u4HU8MjFO9D6z842+neZnQnoE qbit@qhost
The key's randomart image is:
+---[RSA 2048]----+

拷贝公钥到服务器

• 在服务器创建目录

# bash
mkdir .ssh

• 在 Windows 10 上使用 scp 命令上传公钥

C:\Users\qbit\.ssh> scp qbit_rsa.pub [email protected]:/home/qbit/.ssh
[email protected]'s password:
qbit_rsa.pub                         100%  393    12.3KB/s   00:00

将密钥追加到 authorized_keys 文件

# zsh
qbit@qhost ~/.ssh
$ ls
qbit_rsa.pub

qbit@qhost ~/.ssh
$ cat qbit_rsa.pub >> authorized_keys

qbit@qhost ~/.ssh
$ ls
authorized_keys  qbit_rsa.pub

ssh 客户端配置文件

• 在 C:\Users\qbit\.ssh 目录下创建 config 文件，并添加如下内容

Host aliyun
    HostName 112.78.9.10
    Port 22
    User qbit
    IdentityFile C:/Users/qbit/.ssh/qbit_rsa
