Instructions

  1. 在用戶端上生成金鑰對。
[user@rhel8 ~]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa):  <<<  keep empty
Enter passphrase (empty for no passphrase):                    <<<  keep empty
Enter same passphrase again:                                   <<<  keep empty
Your identification has been saved in /home/user/.ssh/id_rsa.
Your public key has been saved in /home/user/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:eVWNNWLhKu/CUTELDr6K4YwCnD1q1TfZG7MumlGW/JY user@rhel8.peeps.lab

The key's randomart image is:
+---[RSA 3072]----+
|             +o=.|
|       . . oo.o o|
|      . o . =.   |
|      ...o +.    |
|. o .  =S.o.     |
|.o = .o=.*+      |
|. * +.o oE*.     |
|.+ + .o..=.      |
|o    o. o...     |
+----[SHA256]-----+

 

  1. 變更為 .ssh 目錄。
[user@rhel8 ~]$ cd .ssh/

 

  1. 使用 ls 以查看檔。
[user@rhel8 .ssh]$ ls
id_rsa  id_rsa.pub  known_hosts

 

  1. 重新命名 id_rsa.pub 的輸出傳送至 authorized_keys。
[user@rhel8 .ssh]$ mv id_rsa.pub authorized_keys

 

  1. 使用 ls 以查看檔。
[user@rhel8 .ssh]$ ls
authorized_keys  id_rsa  known_hosts

 

  1. 使用 SCP 若要將金鑰上傳到「.ssh」目錄的問題。
[user@rhel8 .ssh]$ scp authorized_keys service@XX.XX.XX.XX:/home/service/.ssh

[root@rhel8 .ssh]# ssh service@x.x.x.xx

Additional Information

如果設定無密碼登入的目的是執行 uemcli 指令檔的命令，請參閱知識文章 Dell Unity：UEMCLI 命令停止執行。

新增 -sslpolicy 接受選項可避免 uemcli 指令檔中的命令，防止因憑證到期而停止。
