Update Jenkins from a war file

Question

I have a machine with Ubuntu 12 04 and have installed Jenkins ver  1 424 6 using apt-get based on this guide  but there is a new version   New version of Jenkins  1 447 2  is available for download  changelog     If I press download  I get a jenkins war file    but how do I use that for upgrading my current installation  or is that not possible before the apt repositories gets updated

You can overwrite the existing jenkins war file with the new one and then restart Jenkins   This file is usually located in  usr share jenkins   If this is not the case for your system  in Manage Jenkins - gt  System Information  it will display the path to the  war file under executable-war

Though I wouldn t consider this as a valid answer to OP s question  I d still emphasize that the best way to deploy Jenkins  and likely most if not all libraries packages software  on Ubuntu is to leverage aptitude  or apt-get  management system   It is documented here  https   wiki jenkins-ci org display JENKINS Installing Jenkins on Ubuntu  notice that if you want to use the LTS build  hit on this repo http   pkg jenkins-ci org debian-stable    So if by any chance you actually did use this approach  you d simply do a apt-get upgrade jenkins

https   wiki jenkins io display JENKINS Installing Jenkins on Ubuntu  Once installed like this  you can update to the later version of Jenkins  when it comes out  by running the following commands  ------- sudo apt-get update sudo apt-get install jenkins -------  aptitude or apt-get doesn t make any difference   What does this package do  Jenkins will be launched as a daemon up on start  See  etc init d jenkins for more details  The  jenkins  user is created to run this service  Log file will be placed in  var log jenkins jenkins log  Check this file if you are troubleshooting Jenkins   etc default jenkins will capture configuration parameters for the launch like e g JENKINS HOME By default  Jenkins listen on port 8080  Access this port with your browser to start configuration

I didn t want to install the x11-common and other components that come bundled in the apt-get install approach  so I just downloaded the  war file and ran the command Francois mentioned  That worked nicely  but you have to write your own daemon script with that approach  Full details here  http   strem in stream 9488 Using-the-war-file-for-jenkins-ci

when you open the Jenkins panel it will show available package from their latest version  you can download it via wget command in the server after download the latest package you should take  war backup file   Eg-  wget http   updates jenkins-ci org download war 2 205 jenkins war  Jenkins war file path for Ubuntu -  usr share jenkins   Jenkins war file path for centos -  usr lib jenkins   after taking backup overwrite the war file and restart the jenkins service   Ubuntu - service jenkins restart   centos - systemctl restart jenkins service
