ssh Permission denied (publickey)

 

ssh链接机器是报错：

 

ssh -p 29418 [email protected]
Permission denied (publickey).

 

 

ssh-keygen -t rsa -c "admin" -f ~/.ssh/root

 

原因是上面这个命令生成密钥的时候指定了密钥的文件root，而系统默认的密钥文件名为：id_rsa，所以系统会出现以上错误。

 

解决办法：

1、使用默认密钥文件名id_rsa

2、vim /etc/ssh/ssh_config文件IdentityFile项设置密钥文件为：

IdentityFile  ~/.ssh/root

 

 

 

如下成功：

 

[root@localhost .ssh]# ssh -p 29418 [email protected]
