How to Install Jenkins with a WAR File

Open Source Automation

Open source Jenkins is a popular tool for test automation and for implementing shifting left through continuous integration and continuous deployment. Install Jenkins on Windows (learn how on this BlazeMeter blog) or with a WAR (Web application ARchive) file version of Jenkins. This option can be used on any Java-supporting platform or OS.

First, install JDK. Jenkins supports Java 8. If you don’t know how to install Java, look at this blog. Now that Java is installed, we can proceed with installing a Jenkins WAR file.

Installing a Jenkins WAR File

1. Download latest Jenkins WAR file here.

2. Copy the jenkins.war file to the folder you want. I created a folder named Jenkins in the path C:\Program Files (x86) and copied the jenkins.war file to it.

3. Open the command prompt window and browse to the directory where the jenkins.war file is present, through the command cd C:\Program Files (x86)\Jenkins.

6. Take a look at the line “INFO: Jenkins is fully up and running” that indicates that Jenkins is running. Write down the random password that is auto generated. We will use this password for the initial login later.

8. To unlock Jenkins, paste the random password that you wrote down in the previous step or copy it from the the user account folder, from the file C:\Users\\.jenkins\secrets\initialAdminPassword. Paste it in the Administrator password field and click on the “Continue” button.
