How to add new JENKINS slave nodes (clients)

Set up the jenkins user on the client node

• Create the user jenkins on the node

Passwordless ssh from jenkins server configuration

• If not already done, on the jenkins server enter ssh-keygen -t rsa without specifying a password

Passwordless ssh from jenkins client configuration

• mkdir /home/jenkins/.ssh
• chmod 700 /home/jenkins/.ssh/
• vim .ssh/authorized_keys (<< copy here the content of cat .ssh/id_rsa.pub run on jenkins server home)
• chmod 640 .ssh/authorized_keys
• service sshd restart (as root)

Create the node in Jenkins

• Point your browser to the jenkins instance: http://ci-01.cnaf.infn.it:8080/
• Log in as admin and go to Configura Jenkins -> Gestisci nodi
• Go to New Node
• Insert node name and select the Copy existing node radio button. Specify the node to be copied eg. ci-02
• Modify the following fields according to your desiderata: Name, Description, Labels (important for triggering builds on this node), Host
• Click on the Save button
• The user which performs ssh (jenkins) is already specified. If the node is created from scratch this is another option to be specified.

In order to trigger a build on the already created node, specify the corresponding label in the build options.
