Re: Is it necessary to have passwordless authentication with the jenkins user to other servers?

[Stephen Connolly]

Give Jenkins the SSH key by creating a Credentials in Jenkins that provides the key it is supposed to use.

Using two CentOS 7 servers, I set up passwordless authentication with root users.  I used the same method (with .pub and authorized_key files) with other local users.  But these methods didn't work.  SSH connections between the servers with these users still prompted for a password.

I started with this:  ssh-keygen -t rsa

What can I do to get Jenkins to work?  One of my two CentOS 7 servers has Jenkins installed. I want to do builds (file transfers at the least) with other CentOS 7 servers.  I think I need passwordless authentication for the jenkins user.  I tried appending the contents of the .pub files in /root/.ssh/authorized_keys.  I tried appending the contents of the .pub files in /home/jdoe/.ssh/authorized_keys.  Instead of authorized_keys I also tried authorized_keys2.  I expect passwordless authentication to work the same way with root as other users (as long as I don't enter a password when I generate the SSH key).  But this isn't what I am experiencing. What should I do?
