setting up jenkins with jenkins.war-download Jenkins war

Question

I have installed the latest Jenkins.war from https://updates.jenkins-ci.org/download/war/ after that I have triggered that WAR file as java -jar Jenkins.war in command prompt. As I could understand from the logs that, the port which Jenkins trying to operate on is already in use. I would appreciate if any help on this!

Answer 1

By default, Jenkins will bind on port 8080 (listening address will be http://localhost:8080), you can change this port by editing the jenkins.xml file that is located in the directory where you installed Jenkins. Change it for another value and relaunch. (or try to find who is already listening on this 8080 port, probably a web server)
