By default, Jenkins stores all of its data in this directory on the file system.
There are a few ways to change the Jenkins home directory:
JENKINS_HOME
variable in your Jenkins configuration
file (e.g. /etc/sysconfig/jenkins
on Red Hat Linux).
JENKINS_HOME
environment variable.
JENKINS_HOME
before launching
your web container, or before launching Jenkins directly from the WAR file.
JENKINS_HOME
Java system property when launching your
web container, or when launching Jenkins directly from the WAR file.
web.xml
in jenkins.war
(or its expanded image in
your web container). This is not recommended.
