ssh私鑰登入putty篇

1、安裝openssh、openssh-server

2、啟動sshd：service sshd start

3、設定開機自動啟動sshd：chkconfig --level 35 sshd on

4、建立私鑰公鑰：ssh-keygen -t rsa

[user@centos64 ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/wspjing/.ssh/id_rsa):       //此處直接按回車即可

Enter passphrase (empty for no passphrase):                                //設定私鑰使用密碼，要求4個字元以上

Enter same passphrase again: 

Your identification has been saved in /home/wspjing/.ssh/id_rsa.

Your public key has been saved in /home/wspjing/.ssh/id_rsa.pub.

The key fingerprint is:

fa:a2:fe:4e:8b:ab:dc:cb:73:ab:6f:42:a7:4a:94:52 user@centos64

The key's randomart image is:

+--[ RSA 2048]----+

|                 |

|  E              |

| . .             |

|. o     S        |

| o  . ..         |

|  .. oo          |

| o o+o+o         |

|  ++X&*o.        |

+-----------------+

5、設定公鑰

[user@centos64 ~]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

[user@centos64 ~]$ rm -f ~/.ssh/id_rsa.pub

6、将私鑰 id_rsa 下載下傳到windows系統裡。

7、用puttygen轉換id_rsa，“load”--“All files”--找到“id_rsa”檔案，打開，輸入上面的密碼，會提示“Successfully imported...“，“确定”--“Save private key”，此過程中的其他選項均為預設。

8、打開putty軟體，左邊“Connection”--“Data”，右邊"Auto-login username“後面輸入私鑰對應的使用者名；左邊“Connection”--"SSH"--"Auth“，右邊"Browse..."，找到私鑰檔案，擴充名為"ppk"的檔案；左邊"Session",右邊Host Name下輸入伺服器IP位址，"Save Sessions"下輸入要儲存的快捷名，如"auto",再點選“Save”。

9、點選"open"，提示

Using username "username".

Authenticating with public key "imported-openssh-key"

Passphrase for key "imported-openssh-key":

輸入上面設定的密碼即可
