Jenkins Installation

 Manually installing Jenkins involves a series of steps, including downloading the Jenkins WAR file, configuring the server, and setting up plugins. This process can become repetitive and error-prone, especially when dealing with multiple installations or server rebuilds. By automating the installation via a shell script, you can ensure consistency, reduce the likelihood of human errors, and expedite the setup process.
