I am unable to start the Jenkins server

Can someone help with the steps how set up this jenkins server and please let me know which java version required for set-up jenkins server.

  1. Install jenkins on jenkins server using yum utility only, and start its service. You might face timeout issue while starting the Jenkins service, please refer this link for help.

  2. Jenkin’s admin user name should be theadmin, password should be Adm!n321, full name should be Mark and email should be [email protected].

Note:

  1. For this task, access the Jenkins server by SSH using the root user and password S3curePass from the jump host.

  2. After Jenkins server installation, click the Jenkins button on the top bar to access the Jenkins UI and follow on-screen instructions to create an admin user.

The likely problem here is the java version; I believe it requires at least Java 17, and the standard java install IIRC is either Java 8 or Java 11, neither of which is new enough. So you need to install an appropriate version of Java, or Jenkins will fail to start up. You should see an error in the system logs if your java version is too old; if you install Jenkins as a service, then you can probably see the logs by doing journalctl -u jenkins.
