I've just installed Jenkins on my Ubuntu 15.04. The installation was using 'apt-get' command which ended successfully. But now when I browse 'http://localhost:8080' or 'http://localhost:8080/jenkins' nothing worked. Just tomcat server's page is displayed. How can I browse the Jenkins????? Following is the log file errro:

hudson.util.BootFailure publish

  • Is there any error message in /var/log/jenkins/jenkins.log? – David Levesque Nov 9 '15 at 19:22
  • Hi David, errors are give above from the log file. I've also installed Jave 8 along with Java 7 – MKJ Nov 10 '15 at 2:21

It could be that another instance of Tomcat is already running on port 8080. Try changing the http port in /etc/default/jenkins, e.g. replace this line:


by this one:


then restart Jenkins:

sudo service jenkins restart
