  • 建立SSH的信任关系

    1、在Client上root用户执行ssh-keygen命令,生成建立安全信任关系的证书。 
      Client端
    # ssh-keygen  -t rsa
    Generating public/private rsa key pair.
    Enter file in which to save the key (/root/.ssh/id_rsa): 
    Enter passphrase (empty for no passphrase):            <-- 直接输入回车
    Enter same passphrase again:                           <-- 直接输入回车
    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:
    49:9c:8a:8f:bc:19:5e:8c:c0:10:d3:15:60:a3:32:1c root@Server
      注意:在程序提示输入passphrase时直接输入回车,表示无证书密码。
      上述命令将生成私钥证书id_rsa和公钥证书id_rsa.pub,存放在用户家目录的.ssh子目录中。
     
    2. 将服务器Client的公钥证书id_rsa.pub复制到机器Server的root家目录的.ssh子目录中
     
      Client端
    # scp -p /root/.ssh/id_rsa.pub root@121.40.125.251:/root/.ssh/
    root@192.168.0.20's password:          <-- 输入机器Client的root用户密码
    id_rsa.pub           100% |**************************|   218       00:00
      Server端
    # mv /root/.ssh/id_rsa.pub /root/.ssh/authorized_keys   <--  或者 
    cat id_rsa.pub >authorized_keys
      经过以上2步,就在机器Client的root和机器Server的root之间建立安全信任关系。下面我们看看效果:
     
      Client端
    # scp -i  /root/ .ssh/id_rsa text  root@192.168.0.20:/root
    text                 100% |**************************|    19       00:00
      若ssh端口非22端口,请使用-P参数后跟端口号:
