来源：互联网发布：淘宝怎么转零食店编辑：程序博客网时间：2024/06/07 02:32

1.ssh的安装
gavin@ubuntu:~$ sudo apt-get install ssh

2.生成密钥

gavin@ubuntu:~$ ssh-keygen

Generating public/private rsa key pair.Enter file in which to save the key (/home/gavin/.ssh/id_rsa):         Created directory '/home/gavin/.ssh'.         Enter passphrase (empty for no passphrase):                 Enter same passphrase again:                 Passphrases do not match.  Try again.                 Enter passphrase (empty for no passphrase):                         Enter same passphrase again:                         Your identification has been saved in /home/gavin/.ssh/id_rsa.                         Your public key has been saved in /home/gavin/.ssh/id_rsa.pub.                         The key fingerprint is:                         7f:47:de:fd:11:74:af:5c:89:a4:58:48:5d:c0:21:6a gavin@ubuntu                         The key's randomart image is:                         +--[ RSA 2048]----+                         |         ooo+.   |                         |        o oo     |                         |       E . . . ..|                         |      .   o o o +|                         |        S. . ..oo|                         |         .   + +o|                         |          . . =.o|                         |           . .  o|                         |                .|                         +-----------------+

上述过程会提示输入ssh的登录密码，默认密钥的位置在~/.ssh目录中，这里将公钥改名为authorized_keys

gavin@ubuntu:~/cd .sshgavin@ubuntu:~/.ssh$ mv id_rsa.pub authorized_keys

3.修改配置文件，/etc/ssh/sshd_config

 gavin@ubuntu:~/.ssh$ sudo vi /etc/ssh/sshd_config......# AuthorizedKeysFile  %h/.ssh/authorized_keys.....

这里将AuthorizedKeysFile前的#号去掉即可

4.到windows平台，启动Puttygen，导入先前生成的私钥id_rsa,转换成putty所识别的格式(*.ppk),得到文件id_rsa.ppk.

5.windows上启动putty，进行如下配置
Session-Logging-Hostname:填上你的linux的ip
Windows －Translation －在下拉菜单里选上UTF－8，这里不设置，登录后将会出现中文乱码。
Connection- Data - Auto login username:填上你登录ubuntu时用的用户名。
Connection- SSH-Auth-Private key file for authentication:选上id_rsa.ppk
保存Session配置

6.打开刚刚配置的ssh,成功登录

Using username "gavin".Authenticating with public key "imported-openssh-key"Passphrase for key "imported-openssh-key":Linux ubuntu 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:10:02 UTC 2010 i686 GNU/LinuxUbuntu 10.04 LTSWelcome to Ubuntu! * Documentation:  https://help.ubuntu.com/409 packages can be updated.171 updates are security updates.Last login: Wed Jul  6 06:05:40 2011 from 192.168.27.112gavin@ubuntu:~$

7.其它事项
git带有puttygen工具
密钥的生成也可以直接使用puttygen
也可以不使用密钥机制，这样可以直接使用linux的用户名及密码登录
