We can follow the below steps to upgrade Jenkins in Unix OS -
Step 1
Stop the jenkins service:
sudo systemctl stop jenkins
Step 2
Navigate to the directory where the jenkins.war file is located, and take its backup. You can maybe rename that file:
sudo mv jenkins.war jenkins.war.bk_6_17_2022
Step 3
Download the latest jenkins.war file in the same directory:
sudo wget https://updates.jenkins-ci.org/latest/jenkins.war
Step 4
Change the ownership of the file to root user:
sudo chown root:root jenkins.war
Step 5
Finally, start the jenkins service:
sudo systemctl start jenkins
We can check the status of the service:
sudo systemctl status jenkins
