1、在linux伺服器生成公鑰和私鑰

[root@localhost .ssh]# ssh-keygen 
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:
02:54:da:3a:4e:d4:21:44:9c:f6:47:22:db:50:71:77 [email protected]
The key's randomart image is:
+--[ RSA 2048]----+
|   +=+=.. . E    |
|   .*=.o.. .     |
|   .+*oo         |
|   ..oo .        |
|    + ..S        |
|   o . .         |
|    .            |
|                 |
|                 |
+-----------------+

2、配置檔案開啟祕鑰登入

cat/etc/ssh/sshd_config

RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile   .ssh/authorized_keys

systemctl restart sshd

3、建立認證檔案

touch .ssh/authorized_keys
chmod 700 .ssh/authorized_keys
cat .ssh/id_rsa.pub >> .ssh/authorized_keys

4、將.ssh/id_rsa下載到win客戶端

通過Xshell等工具將祕鑰匯入

選擇匯入祕鑰登入即可
