解决linux中ssh登录Warning:Permanently added (RSA)

发布时间:2017-05-19 11:03:02来源:linux网站作者:天宇骑士
linux中ssh登录出现Warning:Permanently added (RSA) to the list of known hosts提示,以下是解决方法。
 
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
