I am using EC2 and am new to the world of Linux, and I've looked for an answer to this but I think I'm just not sure how to ask the question correctly.

I have installed Jenkins and git using yum, under the account ec2-user, and they install fine. Yum created an account called jenkins which runs the Jenkins process (checked this using ps -aux and the user is jenkins).

I have a remote git repository that uses public/private keys. When I ssh-keygen, and then connect to my remote git repository through ec2-user, everything is fine. I'm just not certain how or where to create a key for the jenkins user.

This is where my trouble starts. When I su jenkins and then cd ~, I wind up in ~ec2-user. When I run ssh-keygen as jenkins, it wants to put the key into /home/ec2-user/.ssh/id_rsa - and that doesn't seem right.

How can I create a key pair for jenkins, or should I just have it added to the ~ec2-user/.ssh/id_rsa?

Don't use su jenkins, use su - jenkins. Then you should inherit the environment of the jenkins user, and key creation etc. should proceed painlessly.

  • The prompt still shows me as ec2-user. Is that correct? – Triple Gilaman Feb 25 '13 at 18:10
  • Jenkins user will not have a shell set up by default (by design), which is why it's dropping immediately back to ec2-user. add -s /bin/bash to the su command to specify a shell. – J. Paulding Jun 04 '14 at 17:51
  • That is an excellent point; would you mind if I edited it into my answer? Or if you would prefer to do the edit, please do, and I'll approve it (though this is somewhat less reliable as I need a second user to approve it). – MadHatter Jun 05 '14 at 12:06
