How to start jenkins on different port rather than 8080 using command prompt in Windows?

Question

I have jenkins.war and I started it from command prompt in Windows as:

java -jar jenkins.war

It was started well and easily browsed as http://localhost:8080

I want to start on 9090 port. How can I do that?

Answer 1

Use the following command at command prompt:

java -jar jenkins.war --httpPort=9090

If you want to use https use the following command:

java -jar jenkins.war --httpsPort=9090

Details are here

Answer 2

Open the jenkins.xml in the jenkins home folder (usually C:\Program Files (x86)\Jenkins) and change the port number:
httpPort=xxxx
to
httpPort=yyyy
then restart the service. it should change the setting permanently.

Answer 3

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 4

In CentOS/RedHat

vim /etc/sysconfig/jenkins

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

change it to any port you want.

Answer 5

On Windows (with Windows Service).

Edit the file C:\Program Files (x86)\Jenkins\jenkins.xml with 8083 if you want 8083 port.

<arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=8083</arguments>

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.

Answer 7

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.

Answer 8

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 9

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

Answer 10

To change the default port of 8080. All you need to do:

1. Goto Jenkins folder present in C:\Program Files (x86)
2. Open a notepad or text pad and run them as administrator and then try opening the jenkins.xml file present in the jenkins folder.
3. Change the port number as below: <arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=9090</arguments>
4. Click Save.

Answer 11

You can call

java -jar jenkins.war --help

to see a list of all available parameters.

Answer 12

Add the following two lines after DAEMON_ARGS in the file /etc/init.d/jenkins

HTTP_PORT=8010
JENKINS_ARGS="--httpPort=$HTTP_PORT"

Answer 13

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 14

On OSX edit file:

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

and edit port to you needs.

Answer 15

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

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

Change 8080 to whichever you want
