Install Jenkins on Redhat 9 with OpenJDK 17

Procedure

1) Configure Jenkins repository

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key
sudo yum upgrade

2) Add required dependencies for the jenkins package

sudo yum install fontconfig java-17-openjdk
sudo yum install jenkins
sudo systemctl daemon-reload

3) Configure to use java-17-openjdk

In my case I need to have java-11 and java-17, i will configure Jenkins service to use jdk 17

I prefere to use vim as system editor

export SYSTEMD_EDITOR=vim

Edit

systemctl edit jenkins --full

Uncomment and define JAVA_HOME

Environment="JAVA_HOME=/usr/lib/jvm/java-17-openjdk"

Save and Quit

4) Start and enable Jenkins service using following commands

sudo systemctl start Jenkins
sudo systemctl status jenkins
