ECS Linux 服务器公钥秘钥SSH登录

Ubuntu 14.04.1为例,设置步骤如下:

 

一. 生成密钥的公钥和私钥

  1. # ssh-keygen -t rsa 

  2. Generating public/private rsa key pair.

    Enter file in which to save the key (/root/.ssh/id_rsa): 

    Created directory '/root/.ssh'.

    Enter passphrase (empty for no passphrase): #输入密码

    Enter same passphrase again:                #输入密码

    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:

                  1c:37:a8:a3:65:a2:4a:89:ab:46:30:ad:54:d1:40:eb root@iZ28vo50eu5Z

二. 将生成的私钥(id_rsa)下载到本地的windows机器上,并把公钥导入到.ssh/authorized_keys 文件中去

#  cd /root/.ssh/

  1. #cat id_rsa.pub > authorized_keys 

三. 设置sshd  服务器服务,打开以下设置:

 

  1. RSAAuthentication yes 

  2. PubkeyAuthentication yes

  1. AuthorizedKeysFile      /root/.ssh/authorized_keys 

  2.  修改以下设置: 

  3. ChallengeResponseAuthentication no 

  4. PasswordAuthentication no 

  5. UsePAM no 

四. 重启ssh服务

  1. #service ssh  restart 

五. 导入私钥到远程工具中,比如xshell。

     新建连接,点击左边用户身份验证:
