In CentOS/RedHat (assuming you installed the jenkins package)

vim /etc/sysconfig/jenkins

....
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8080"

change it to any port you want.

Correct, use --httpPort parameter. If you also want to specify the $JENKINS_HOME, you can do like this:

java -DJENKINS_HOME=/Users/Heros/jenkins -jar jenkins.war  --httpPort=8484

On OSX edit file:

/usr/local/Cellar/jenkins-lts/2.46.1/homebrew.mxcl.jenkins-lts.plist

and edit port to you needs.

Answer 6

For the benefit of Linux users who find themselves here: I found /etc/sysconfig/jenkins has a JENKINS_PORT="8080", which you should probably change too.
