明明没有错,为什么一直Faild.(PS:如图所示,假装是个Faild)
这一步困扰了一天多的时间,网上有说设置.shh权限的,有说修改sshd_config 文件的...通通不适用我的问题.
先看第一个问题:
==========================
Creating target directory...
==========================
Command start time 2018-11-19 00:35:59
Warning: Permanently added 'hdp21,192.168.163.21' (ECDSA) to the list of known hosts.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
SSH command execution finished
host=hdp21, exitcode=255
Command end time 2018-11-19 00:35:59
ERROR: Bootstrap of host hdp21 fails because previous action finished with non-zero exit code (255)
ERROR MESSAGE: Warning: Permanently added 'hdp21,192.168.163.21' (ECDSA) to the list of known hosts.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
STDOUT:
Warning: Permanently added 'hdp21,192.168.163.21' (ECDSA) to the list of known hosts.
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
大功告成.希望为这个问题困扰良久的你带来快乐!
