Enter same passphrase again:
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:
b4:51:7e:1e:52:61:cd:fb:b2:98:4b:ad:a1:8b:31:6d root@node1.ehowstuff.local
The key's randomart image is:
+--[ RSA 2048]----+
| . ++ |
| o o o |
| o o o . |
| . o + .. |
| S . . |
| . .. .|
| o E oo.o |
| = ooo. |

用 ssh-copy-id 命令将公钥复制或上传到远程主机，并将身份标识文件追加到节点2的 ~/.ssh/authorized_keys 中：
复制代码
[root@node1 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.0.10
root@192.168.0.10's password:
Now try logging into the machine, with "ssh '192.168.0.10'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
步骤四：
验证免密码 SSH 登录节点2：
复制代码
[root@node1 ~]# ssh root@192.168.0.10
