Jenkins Gerrit 触发器 - “/var/lib/jenkins/.ssh/id_rsa”不是有效的密钥文件

Question

I've installed Jenkins in an Ubuntu server by following the documentation from Jenkins Install documentation and I am trying to set up Gerrit Trigger Plugin . While setting up Administrative Settings section the SSH Keyfile section always gives the error "/var/lib/jenkins/.ssh/id_rsa" is not a valid key file.

I've generated the ssh keys as the Jenkins user in the default location "/var/lib/jenkins/"

I've tried generating the keys with ssh-keygen , ssh-keygen -t rsa , ssh-keygen -t rsa -b 2048 and the keys are generated with and without a passphrase also as pem file but still shows as invalid key file.

The files are present in the "/var/lib/jenkins/.ssh/" location

jenkins@jenkins:~/.ssh$ ls -la
total 16
drwx------  2 jenkins jenkins 4096 Oct  9 14:18 .
drwxr-xr-x 17 jenkins jenkins 4096 Oct  9 14:18 ..
-rw-------  1 jenkins jenkins 2602 Oct  9 14:05 id_rsa
-rw-r--r--  1 jenkins jenkins  569 Oct  9 14:05 id_rsa.pub

I didn't find any log entries regarding this in jenkins log file also not in the web portal System Log section.

Answer 2

我遇到了同样的问题， ssh-keygen -m PEM 为我工作

Answer 3

Following are the steps worked for me.

1. Currently my Jenkins home directory is pointing to /home/home_for_jenkins .And I need to use a different BOT user to fetch the Gerrit events.

2. In order to achieve the above requirement, I have generated ssh keys for BOT user by using ssh-keygen -m PEM command and copied the generated keys to /home/home_for_jenkins folder and changed the permissions accordingly
