How to Add Jenkins Slave to Master

Still now we have setup the Jenkins and executed some sample now. This helps only building/running job only on master server. If we have parallel build or multiple jobs needs to be perform single server won’t help much, either we may need more hardware or additional server. For that Jenkins is giving master-slave feature, which helps to run then build or jobs on multiple servers.

Jenkins Master Slave

In this post we should like to demonstrate how to create a master-slave environment in Jenkins. Jenkins makes it possible to configure multiple nodes as slave.

# firewall-cmd –reload

Start Jenkins

# systemctl restart jenkins.service

Step2: Installing Slave Linux and Windows

Install java using following command,
