Installing jenkins, lab: install jenkins on a vm

kishlay-raj · March 12, 2022, 11:44am

I am following this instruction on centos in lab to install jenkins and also updating port but i am getting some issue or unable to start jenkin service

sudo yum install epel-release -y
sudo yum install java -y
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo --no-check-certificate
sudo rpm --import http://pkg.jenkins.io/redhat-stable/jenkins.io.key
sudo yum install jenkins -y

I am getting error upon starting the service
Job for jenkins.service failed because the control process exited with error code. See “systemctl status jenkins.service” and “journalctl -xe” for details.

Please reply.

Can you share the output of systemctl status jenkins.service ?

This definitely does not work with the official instructions in the lab environment. I was able to get past the issue by installing the Jenkins Docker container.

Output of systemctl start jenkins is below

I have the same issue. Tried yesterday, tried today. So far I haven’t been able to solve the problem.

Hello, @kishlay-raj
Thanks for sharing an error screenshot. One of our team members is working on it.
Please be patience.

Regards,

@kishlay-raj
In case, If you wanna troubleshoot and fix this issue please follow the below instructions -

sudo journalctl -xe -u jenkins

You will see the error that it’s happening due to a failed to bind port.

sudo systemctl status jenkins

you will see the unit file of this jenkins.

sudo vi /usr/lib/systemd/system/jenkins.service

change the JENKINS_PORT=“8080” to “8090”
then reload the daemon because we made some changes in the unit files and then restart the jenkins service.

sudo systemctl daemon-reload

sudo systemctl restart jenkins

sudo systemctl status jenkins

after that it’s good to go to explore Jenkins UI.

Hello Tej_Singh_Rana

I am struggling with the same error message, I have changed the PORT to 8090 but still getting same error message on Jenkins installation.

that’s odd. Let me check and get back to you.

Tej_Singh_Rana · June 13, 2022, 6:05pm

I checked the lab and didn’t see any issues.

Please give it another try and let me know how’s it going this time.

Regards,

pratikesh-surve · August 13, 2022, 5:51am

Thanks it works for me.

hello,
i have the same error , i change the port and i restart jenkins but i still getting this error.
Any solution?

nabil_code · February 24, 2024, 9:44am

Ok, found the issue. Instead of editing /usr/lib/systemd/system/jenkins.service edit /lib/systemd/system/jenkins.service. And it should work fine.

rvsathiyavasagan · April 2, 2024, 4:16pm

I’m also getting same error, I couldnt start the service after changed port no.

al1 · April 2, 2024, 5:02pm

Please don’t post the same message or question in multiple threads.

rvsathiyavasagan · April 3, 2024, 2:27pm

I apologize, I’ve now shared the logs in an other post.
Kindly check .
