SSH Issue with Ambari 2.1 & Debian 7

[#1]

Doing the install on Debian7, but we keep running into problems with SSH. Here is the description of issue:

We are able to SSH to all of the instances from the terminal.

But the Host registration in Ambari fails. Please scroll all the way down for the error.

We tried modifying the directory permissions as per our recommended guide and it still did not work.

Looks like Ambari copies the RSA file to a folder under /var/run/ambari-server/bootstrap under a filename called SSHKEY

That file contains the private key. In our case however, the file shows NULL

We are wondering if this may be a glitch on the Ambari side.

Just to confirm, ssh from ambari server to all the host works fine "password less ssh". Correct?

Did you use correct private key in ambari console while installing?

[#3 · Accepted solution]

Using that key and signed into the Ambari Server as 'root', can you SSH to the target hosts from a command line?

If you can't, double check the permissions of the "public" key on the target hosts.

~/.ssh should be 700

and the authorized_keys file should be 600.
