I am setting up Ambari.

After I give localhost.localdomain for FQDN and specify the Key.. I get following error:

~~~~~~~~~~~~~Copy from the screem~~~~~

========================== Creating target directory... ========================== Command start time 2016-07-25 09:58:07 Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

The issue is with ssh and keygen. Please verify if you are able to login to the machine without password as ssh.

[#3]

I am able to login "ssh admin@localhost" without giving any password

I am able to login without password, please refer attached image.

Is this a single node cluster? I can see that you are getting error related to ssh while bootstrapping ambari agent. Is there any reason why are you using localhost.localdomain? do you have localhost.localdomain entry in your /etc/hosts file which is pointing to 127.0.0.1 ? I would suggest double check your /etc/hosts file.

[#8]

Yes, I just verified the entry is there.

[#9]

Is the issue resolved?

Delete the .ssh folder. Create the new key and try it again.

One more suggestion Check the status selinux if it is not disable then you have to disable it or run following command "restorecon -R .ssh" and try to do ssh.
