解决linux中ssh登录Warning:Permanently added (RSA) to the list of known hosts

原因:

在执行scp id_rsa.pub root@hostname:/root/.ssh这一步时,没在本机的/root/.ssh下生成known_hosts文件。

 

解决方案:

vi /etc/ssh/ssh_config

最后有两行是

         StrictHostKeyChecking no

         UserKnownHostsFile /dev/null

把这两行注释掉并保存文件

再次执行scp id_rsa.pub root@host141:/root/.ssh

出现提示

The authenticity of host 'host141 (172.20.0.141)' can't be established.

RSA key fingerprint is a0:09:89:d2:3b:aa:91:60:59:7f:7f:bc:03:31:b0:09.

Are you sure you want to continue connecting (yes/no)? 

输入yes后,则可看到在/root/.ssh目录下生成了known_hosts文件:

[root@SamuluIndex .ssh]# ls

id_rsa  id_rsa.pub  known_hosts
