Setting up jenkins on centos: problems with ssh keys and git

Question

Went through a lot of questions, but nothing seems to be solving my issue. Or to be more precise I am not sure if I am doing the whole thing correctly. So here it is:

Have installed centos 6.3 OS. Then I followed the following guide to install jenkins:

https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+RedHat+distributions

Jenkins works fine. Now I am trying to set up a simple build job, which requires to clone a git repository. (I've installed git plugin)

In repository URL i type the following: git@gitserver:myrepo.git Of course I get an error: stderr: Host key verification failed.

ok, I need to generate ssh keys and all will be good. So I do the following:

su - jenkins

but unfortunately it doesn't switch to jenkins user.

cat /etc/passwd

shows the following:

jenkins:x:496:492:Jenkins Continuous Build Server:/var/lib/jenkins:/bin/false

so seems that it doesn't have a usual home directory.

The question is how do I generate keys for jenkins or if the above steps where not the right way to do it, how do I fix it?

Thanks a lot!

Update: I generated keys (as a root user) and placed them in jenkins home and did exactly and copied public key to git server. Still didn't help.

When I look at the log of the build it says:

Started by user anonymous
Building in workspace /var/lib/jenkins/jobs/myrepo/workspace

this user anonymous is this another user created by jenkins, or is it still jenkins that runs the commands?

Answer 1

I'm assuming that you have root access if you were able to install the Jenkins RPM. Were you su-ing to the jenkins user while logged in as root ? If not, you should do so or use

sudo su - jenkins

if your logged in user has sudo access.

Then run

ssh-keygen -t rsa

to generate an RSA keypair for the jenkins user, and you can upload the public key to your git server. The key will be generated as /var/lib/jenkins/.ssh.id_ra.pub if you take the defaults.

Answer 2

1 change user jenkins login setting

vi /etc/passwd

update /bin/false to /bin/bash

2 su - jenkins

jekins user home would be /var/lib/jenkins

3 ssh-keygen

cat .ssh/id_rsa.pub

copy this key to bitbucket

4 ssh [email protected]

this is going to set the bitbucket ssh key in .ssh/known_hosts

Now you should be able to access
