登入金鑰對

1. 載入用戶 demo 的環境變數。

   [root@controller ~]# . demo.token
   

2. 如果 .ssh 目錄沒有金鑰對，就先執行 ssh-keygen 產生。

   [root@controller ~]# ssh-keygen -q -N ""
   Enter file in which to save the key (/root/.ssh/id_rsa): ^C
   [root@controller ~]# ll .ssh/
   total 16
   -r--------. 1 root root  788 May 22 17:50 authorized_keys
   -rw-------. 1 root root 1675 May 22 17:50 id_rsa
   -rw-r--r--. 1 root root  392 May 22 17:50 id_rsa.pub
   -rw-r--r--. 1 root root 1139 May 22 19:25 known_hosts
   

3. 將 public key 加到 openstack，設定名為 mykey。

   [root@controller ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
   +-------------+-------------------------------------------------+
   | Field       | Value                                           |
   +-------------+-------------------------------------------------+
   | fingerprint | 2d:0a:a2:58:e1:e7:f6:bd:55:c8:6f:27:9d:64:be:d9 |
   | name        | mykey                                           |
   | user_id     | 0d7bb3820384452abb97ec0b40c445b1                |
   +-------------+-------------------------------------------------+
   

4. 確認 openstack 有 mykey 的金鑰對。

   [root@controller ~]# openstack keypair list
   +-------+-------------------------------------------------+
   | Name  | Fingerprint                                     |
   +-------+-------------------------------------------------+
   | mykey | 2d:0a:a2:58:e1:e7:f6:bd:55:c8:6f:27:9d:64:be:d9 |
   +-------+-------------------------------------------------+
