SSH提示Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

今天同事搞hadoop免密，把服务器搞垮了，ssh登陆提示：Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

还好，之前初始化已经再其他用户做了免密，才能登陆，网上找了好就都没有正确答案，最终按照自己的思路解决了

1、yum删除现有的openssh-server，然后重新安装openssh-server

#yum -y remove openssh-server

#yum -y install openssh-server

2、重启sshd服务

#systemctl restart sshd.service

 

就这两步解决
