Jenkins : JenkinsLinuxStartupScript

This is a startup script for Linux, and provides start/stop/restart/status functionality. This has been tested on Redhat, but should work on other Linuxes like Ubuntu or SuSE. You may need to change the environment variables at the top of the script to fit your system. This assumes that Jenkins is installed in /home/jenkins, Tomcat is installed in /home/jenkins/apache-tomcat-6.0.18, and that JENKINS_HOME is /home/jenkins/jenkins-home

To install, on Ubuntu:

Save the file to /etc/init.d/jenkins
chmod a+x /etc/init.d/jenkins
update-rc.d jenkins defaults
