現有2臺機器
1、服務器192.168.1.112
2、個人機192.168.1.110
要使110無需密碼通過ssh登入112
步驟
1、創建密鑰
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、複製公密到服務器
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的信任區域
miao@debian-192-168-1-112:~/.ssh$ cat 192.168.1.110 >> authorized_keys
miao@debian-192-168-1-112:~/.ssh$ 注： 2，3兩步可由命令ssh-copy-id一步到位
miao@ubuntu-192-168-1-110:~/.ssh$ ssh-copy-id [email protected]
Password:
Now try logging into the machine, with "ssh '[email protected]'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
4、啓動ssh-agent
如果ssh 192.168.112返回 Agent admitted failure to sign using the key
ps -Af|grep agent查看有無ssh-agent有無運行，若沒有
miao@u32-192-168-1-110:~/.ssh$ ssh-agent5、添加id_rsa到ssh-agent
miao@u32-192-168-1-110:~/.ssh$ ssh-add id_rsa6、完成
