linux ubuntu jenkins

Solution 1

First open the /etc/default/jenkins file.
Then under JENKINS_ARGS section, you can change the port like this HTTP_PORT=9999.

Then you should restart Jenkins with sudo service jenkins restart.

Then to check the status use this command sudo systemctl status jenkins

Solution 2

For others still looking for answers you can go to /etc/sysconfig/jenkins in CentOS/RHEL or /etc/default/jenkins in Debian based distributions and change the JENKINS_PORT= variable to whatever port you want. Restart jenkins, and it should be running on your desired port.

Solution 3

First, run this command to open jenkins configurations:
```
 sudo nano /etc/default/jenkins
```

The only part you need to change is:

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

There you need to change to the desired port. For example:

 HTTP_PORT = 8081

Finally, Restart Jenkins service by running this command:
```
 sudo service jenkins restart
```

Then you're ready to open it with a new port.

Solution 4

In my case,I add

 HTTP_PORT="XXXX"
 JENKINS_ARGS="--httpPort=XXXX"

when defining the variables at the beginning of /etc/default/jenkins,it works .

Solution 5

step 1 : sudo nano /etc/default/jenkins open the nano file And change HTTP PORT:8080 to HTTP PORT : 8081

CTL+X and Click Y and ENTER

PORT will changing from 8080 to 8081 restart the jenkins

sudo service jenkins restart

I am trying to install jenkins in ubuntu. I have followed the commands below:
```
wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | apt-key add -

echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list
```
then
```
apt-get update
```
and
```
apt-get install jenkins
```
but It shows
- Starting Jenkins Continuous Integration Server Jenkins The selected http port (8080) seems to be in use by another program Please select another port to use for jenkins
Need help on how to set a different port for Jenkins to run.

i have set port 8081.How to invoke jenkins??

Just restart the service as specified above and then go in your browser at http://127.0.0.1:8081. The Jenkins page should be there if there were no errors.

I was able to do with localhost:8081.Thanks

This solution gave me the hint I needed - In my case I was able to edit this file and change the following line: HTTP_PORT=8080 which was referenced already in the JENKINS_ARGS line at the bottom of the file.

On Debian-based distros it's still /etc/default/jenkins. It's /etc/sysconfig/jenkins for RHEL/CentOS.

You only need HTTP_PORT, the JENKINS_ARGS is redundant.

On Debian-based distros the var is HTTP_PORT now
