Answer 1

If you have configured jenkins on ec2 instance with linux AMI and looking to change the port. Edit the file at

sudo vi /etc/sysconfig/jenkins

Edit

JENKINS_PORT="your port number"

Exit vim

:wq

Restart jenkins

sudo service jenkins restart

Or simply start it, if its not already running

sudo service jenkins start

To verify if your jenkins is running on mentioned port

netstat -lntu | grep "your port number"

Answer 2

With Ubuntu 14.4 I had to change the file /etc/default/jenkins

E.g.

   #HTTP_PORT=8080
   HTTP_PORT=8083

and restart the service

service jenkins restart

Answer 3

For Fedora, RedHat, CentOS and alike, any customization should be done within /etc/sysconfig/jenkins instead of /etc/init.d/jenkins. The purpose of the first file is exactly the customization of the second file.

So, within /etc/sysconfig/jenkins, there is a the JENKINS_PORT variable that holds the port number on which Jenkins is running.

Answer 4

You can call

java -jar jenkins.war --help

to see a list of all available parameters.

Answer 5

Change the '/etc/init.d/jenkins' shell

check_tcp_port "http" "$HTTP_PORT" "8080" || return 1

Change 8080 to whichever you want

Answer 6

In *nix In CentOS/RedHat

vim /etc/sysconfig/jenkins

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

In windows open XML file C:\Program Files (x86)\Jenkins\jenkins.xml

<executable>%BASE%\jre\bin\java</executable>
  <arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --**httpPort=8083**</arguments>
 i made  above bold  to show you change then 
 <executable>%BASE%\jre\bin\java</executable>
  <arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=8083</arguments>

now you have to restart it doesnot work unless you restart http://localhost:8080/restart then after restart http://localhost:8083/ all should be well so looks like the all above response which says it does not work We have restart.
