How to change port for jenkins window service when 8080 is being used

Question

I installed Jenkins on a windows virtual server and want to run it as window service.

Since the port 8080 is being used by other service, I changed the http port to 8081 in jenkins.xml file. However, I am not able to launch localhost:8081/jenkins at all. I need detail instruction/steps to configure port 8081 or something to run Jenkins.

I follow the answer to change port to 8090 but Jenkins still runs at 8080 port. Anybody knows why? (note: I even clear Windows virtualstore files of my current account) — Scott Chu, May 08 '17 at 03:19

Go to the directory where you installed Jenkins (by default, it's under Program Files/Jenkins)
Open the Jenkins.xml configuration file
Search --httpPort=8080 and replace the 8080 with the new port number that you wish
Restart Jenkins for changes to take effect

The running instance of Jenkins does not see the changes done in this file. They are only applied at startup time. – Thorbjørn Ravn Andersen Jun 14 '19 at 10:11

4. To restart Jenkins, go to the directory Jenkins is installed(e.g.: C:/Program Files(x86)/Jenkins) via Command Prompt & type 'jenkins.exe restart' (without quotes of course). https://stackoverflow.com/a/14869398/8696237 – Sandun Jul 20 '19 at 07:03

You can restart the jenkins from url like "http://jenkins_host_url:port/restart" after Jenkins.xml is updated. – fgul Dec 27 '19 at 07:34

Restart Jenkins service

Just restart the Jenkins service after you changed the port in jenkins.xml.

Press Win + R
Type "services.msc"
Right click on the "Jenkins" line > Restart
Type http://localhost:8081/ in your browser to test the change.

On Ubuntu 16.04 LTS you can change the Port like that:

Change port number in the config file /etc/default/jenkins to 8081 (or the port you like) HTTP_PORT=8081
Restart Jenkins: service jenkins restart

If you are running on Redhat, do following

Stop Jenkins
$sudo service jenkins stop
change port number in /etc/sysconfig/jenkins like i did for port 8081
JENKINS_PORT="8081"
start Jenkins again
$sudo service jenkins start

make sure your FW has correct burn rules.

You should follow 2 steps:

This step can be followed by running the cmd in the specific folder location where there will be .war file. This step helpful as Jenkins needs some disk space to perform builds and keep archives.
```
set JENKINS_HOME=c:\folder\Jenkins
```
This step will be helpful to change the port number, and works can be performed accordingly.
```
java -jar jenkins.war --httpPort=8585
```

While this code may solve the question, [including an explanation](//meta.stackexchange.com/q/114762) of how and why this solves the problem would really help to improve the quality of your post, and probably result in more up-votes. Remember that you are answering the question for readers in the future, not just the person asking now. Please [edit] your answer to add explanations and give an indication of what limitations and assumptions apply. – double-beep Aug 05 '19 at 07:32

Changing Jenkins Port (METHOD 1)

sudo nano /etc/default/jenkins

Scroll down until you find the following lines:

# port for HTTP connector (default 8080; disable with -1)

HTTP_PORT=8080

Edit the second line to include the port number you want to specify. For instance:

HTTP_PORT=8081

Restart Jenkins:

sudo systemctl restart jenkins

Changing Jenkins Port (METHOD 2)

Populate /lib/systemd/system/jenkins.service with configuration parameters for the launch To change jenkins port, set Jenkins to listen on port <PORT_NUMBER>:

Open systemd service file:
sudo vi /lib/systemd/system/jenkins.service

change port:

[Service]
Environment="JENKINS_PORT=9191"

Reload units:
sudo systemctl daemon-reload

Restart jenkins:
sudo systemctl restart jenkins

1 ) Open the jenkins.xml file
2 ) Search for the "--httpPort=8080" Text and replace the port number 8080 with your custom port number (like 7070 , 9090 )
3 ) Go to your services running your machine & find out the Jenkins service and click on restart.

Use Default Port

If the default port 8080 has been bind with other process, Then kill that process.

DOS> netstat -a -o -n

Find the process id (PID) XXXX of the process which occupied 8080.

DOS> taskkill /F /PID XXXX

Now, start Jenkins (on default port)

DOS> Java -jar jenkins.war

Use Custom Port

DOS> Java -jar jenkins.war --httpPort=8008

There are multiple ways to run Jenkins when the default port "8080" is already bind with other process. Option-1: Kill the process which occupies 8080 Example: C:\Users\maris>netstat -a -n -o | find "8080" TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 2900 TCP [::]:8080 [::]:0 LISTENING 2900 C:\Users\maris>taskkill /PID 2900 /F SUCCESS: The process with PID 2900 has been terminated.

edit HTTP_PORT in config file:

sudo nano /etc/default/jenkins
# update
# HTTP_PORT=1234
# set any port you want

If this doesn't resolve the issue, set the port in jenkins.service file:

sudo nano /lib/systemd/system/jenkins.service
# update
# Environment="JENKINS_PORT=1234"
# set any port you want
sudo nano /etc/systemd/system/jenkins.service.d/override.conf
# update
# Environment="JENKINS_PORT=1234"
# set any port you want

Then restart the service by:

sudo systemctl daemon-reload
sudo systemctl restart jenkins.service
# check status by:
sudo systemctl status jenkins.service

Note: to check if a port is available to use, run:

sudo lsof -i -P -n | grep 'port_number'
# no result will show if port_number is not being used.

For Ubuntu there is a small change in paths etc:

First, you need to open the Jenkins config file:

Path for GUI:

/etc/default/jenkins

Command for terminal:

sudo nano /etc/default/jenkins

Note: instead of nano you can use vi, cat, etc

find HTTP_PORT

replace 8080 to any port like:

HTTP_PORT=8282

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>

For jenkins in a docker container you can use port publish option in docker run command to map jenkins port in container to different outside port.

e.g. map docker container internal jenkins GUI port 8080 to port 9090 external

docker run -it -d --name jenkins42 --restart always \
   -p <ip>:9090:8080 <image>

Note that since Jenkins 2.332.1, this won't work anymore, as described in the accepted answer of this post. Basically, you have to configure Jenkins using systemctl by typing

systemctl edit jenkins

then, pass in:

[Service]
Environment="JENKINS_PORT=<anyPort>"
