What is Jenkins?

Jenkins is actually a very simple job monitor, very much like NETBATCH in Tandem.(What else Tandem professional can say J ). There, You create jobs that run either on

• a Calendar,
• an Interval
• OR Triggered by an external event.

What makes Jenkins is really useful, is the large set of plugins that have been written by Jenkins community.

PLUGINS

• There are plugins that monitor GIT – so that when someone pushes code to GITHUB enterprise or Bitbucket server, a Jenkins job will automatically gets started.
• There are SSH Plugins that allow you to run commands or even other parts of jobs on other systems.
• There are packaging plugins, email plugins that send results to a team.
• Hipchat plugins that can send a message to your phone when is job fails.

Jobs are run by executors like in NETBATCH.

How to setup?

• Download the Jenkins WAR file
• Run in using JAVA.

Nohup is there, to make sure Jenkins does NOT step when your terminal session ends.
