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
miao@u32-192-168-1-110:~/.ssh$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase): (忽略)
Enter same passphrase again: (忽略)
Your identification has been saved in /home/miao/.ssh/id_rsa.
Your public key has been saved in /home/miao/.ssh/id_rsa.pub.
2、复制公密到服务器
miao@u32-192-168-1-110:~/.ssh$ scp id_rsa.pub
[email protected]:/home/miao/.ssh/192.168.1.110
[email protected]'s password:
id_rsa.pub 100% 404 0.4KB/s 00:00
miao@u32-192-168-1-110:~/.ssh$
3、添加公密到192.168.112的信任区域
miao@debian-192-168-1-112:~/.ssh$ cat 192.168.1.110 >> authorized_keys
miao@debian-192-168-1-112:~/.ssh$
4、启动ssh-agent
如果ssh 192.168.112返回 Agent admitted failure to sign using the key
ps -Af|agent查看有无ssh-agent有无运行,若没有
miao@u32-192-168-1-110:~/.ssh$ ssh-agent
5、添加id_rsa到ssh-agent
miao@u32-192-168-1-110:~/.ssh$ ssh-add id_rsa
6、完成
