现有2台机器

1、服务器192.168.1.112

2、个人机192.168.1.110

要使110无需密码通过ssh登入112

步骤

1、创建密钥

  1. miao@u32-192-168-1-110:~/.ssh$ ssh-keygen -t rsa  
  2.   
  3. Generating public/private rsa key pair.  
  4. Enter passphrase (empty for no passphrase): (忽略)  
  5. Enter same passphrase again: (忽略)  
  6. Your identification has been saved in /home/miao/.ssh/id_rsa.  
  7. Your public key has been saved in /home/miao/.ssh/id_rsa.pub.  
2、复制公密到www.linuxidc.com服务器 
  1. miao@u32-192-168-1-110:~/.ssh$ scp id_rsa.pub [email protected]:/home/miao/.ssh/192.168.1.110  
  2. [email protected]'s password:   
  3. id_rsa.pub                                                                   100%  404     0.4KB/s   00:00      
  4. miao@u32-192-168-1-110:~/.ssh$   
3、添加公密到192.168.112的信任区域 
view plain
  1. miao@debian-192-168-1-112:~/.ssh$ cat 192.168.1.110 >> authorized_keys  
  2. miao@debian-192-168-1-112:~/.ssh$   

注: 2,3两步可由命令ssh-copy-id一步到位 
view plain
  1. miao@Ubuntu-192-168-1-110:~/.ssh$ ssh-copy-id [email protected]  
  2. Password:  
  3. Now try logging into the machine, with "ssh '[email protected]'", and check in:  
  4.   
  5.   .ssh/authorized_keys  
  6.   
  7. to make sure we haven't added extra keys that you weren't expecting.  

4、启动ssh-agent 

如果ssh 192.168.112返回 Agent admitted failure to sign using the key 
ps -Af|grep agent查看有无ssh-agent有无运行,
miao@u32-192-168-1-110:~/.ssh$ ps -Af|grep agent
5、若没有 添加id_rsa到ssh-agent
miao@u32-192-168-1-110:~/.ssh$ ssh-agent
