解决linux中ssh登录Warning:Permanently added (RSA) to the list of known hosts
远程登录==>
[root@i-nbje0lea .ssh]# ssh 192.168.9.10
Warning: Permanently added '192.168.9.10' (RSA) to the list of known hosts.
Last login: Fri Sep 25 15:37:49 2015 from 192.168.9.11
报Warning:Permanently added (RSA) to the list of known hosts错误
因:在执行ssh 时,没在本机的~/.ssh下生成known_hosts文件。
解决方案:
# vi/etc/ssh/ssh_config //注意是客户端设置文件
最后有两行是
StrictHostKeyChecking no #登录时是否询问
UserKnownHostsFile /dev/null #表示隐藏known_hosts文件
两行解释如下:
StrictHostKeyChecking
If this flag is set to “yes”, ssh(1) will never automatically add host keys to the
~/.ssh/known_hosts file, and refuses to connect to hosts whose host key has changed.The default is “ask”.
UserKnownHostsFile
Specifies a file to use for the user host key database instead of ~/.ssh/known_hosts.
把这两行注释掉并保存文件
再次执行ssh 192.168.9.10
出现提示
[admin@i-nbje0lea .ssh]$ ssh 192.168.9.10
The authenticity of host '192.168.9.10 (192.168.9.10)' can't be established.
RSA key fingerprint is 50:e9:44:87:86:c3:0f:85:ab:41:5e:33:1e:5b:6a:c1.
Are you sure you want to continue connecting (yes/no)? yes

输入yes后,则可看到在/root/.ssh目录下生成了known_hosts文件:
[root@host100.ssh]# ls
id_rsa id_rsa.pub known_hosts
