Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
解决 Permanently added 'hdp21,192.168.163.21' (ECDSA) to the list of known hosts. 其实仔细看问题很好解决,know hosts 是不是很眼熟,不错,就是.ssh 目录下的文件.

 

问题的关键在于要把hdp21 那条数据放在第一行,(PS原先hdp21 的数据在末尾一行)

第二个问题:
==========================
Creating target directory...
==========================

Command start time 2018-11-19 21:14:19

Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
SSH command execution finished
host=hdp21, exitcode=255
Command end time 2018-11-19 21:14:19

ERROR: Bootstrap of host hdp21 fails because previous action finished with non-zero exit code (255)
ERROR MESSAGE: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

STDOUT:
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
问题其实已经很明显了 ,Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

解决方案:请看一下authorized_keys 文件是否有服务器自己的公钥内容.免密登录不但需要把自己的公钥给其他服务器,还要设置一份给自己的公钥. 

[root@hdp21 ~]# ssh-copy-id -i .ssh/id_rsa.pub root@hdp21
